Cyclone mitigation encompasses the actions and planning taken before a tropical cyclone strikes to mitigate damage and injury from the storm. Knowledge of tropical cyclone impacts on an area help plan for future possibilities. Preparedness may involve preparations made by individuals as well as centralized efforts by governments or other organizations. Tracking storms during the tropical cyclone season helps individuals know current threats. Regional Specialized Meteorological Centers and Tropical Cyclone Warning Centers provide current information and forecasts to help individuals make the best decision possible.

Tropical cyclone Is a rotating storm system

A tropical cyclone is a rapidly rotating storm system characterized by a low-pressure center, a closed low-level atmospheric circulation, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain. Depending on its location and strength, a tropical cyclone is referred to by different names, including hurricane, typhoon, tropical storm, cyclonic storm, tropical depression, and simply cyclone. A hurricane is a tropical cyclone that occurs in the Atlantic Ocean and northeastern Pacific Ocean, and a typhoon occurs in the northwestern Pacific Ocean; in the south Pacific or Indian Ocean, comparable storms are referred to simply as "tropical cyclones" or "severe cyclonic storms".

Tropical cyclones out at sea cause large waves, heavy rain, flood and high winds, disrupting international shipping and, at times, causing shipwrecks. [1] On land, strong winds can damage or destroy vehicles, buildings, bridges, and other outside objects, turning loose debris into deadly flying projectiles. The storm surge, or the increase in sea level due to the cyclone, is typically the worst effect from landfalling tropical cyclones, historically resulting in 90% of tropical cyclone deaths. [2] The broad rotation of a landfalling tropical cyclone, and vertical wind shear at its periphery, spawns tornadoes. Tornadoes can also be spawned as a result of eyewall mesovortices, which persist until landfall. [3]

Flood Overflow of water that submerges land that is not normally submerged

A flood is an overflow of water that submerges land that is usually dry. In the sense of "flowing water", the word may also be applied to the inflow of the tide. Floods are an area of study of the discipline hydrology and are of significant concern in agriculture, civil engineering and public health.

Wind Flow of gases or air on a large scale

Wind is the flow of gases on a large scale. On the surface of the Earth, wind consists of the bulk movement of air. In outer space, solar wind is the movement of gases or charged particles from the Sun through space, while planetary wind is the outgassing of light chemical elements from a planet's atmosphere into space. Winds are commonly classified by their spatial scale, their speed, the types of forces that cause them, the regions in which they occur, and their effect. The strongest observed winds on a planet in the Solar System occur on Neptune and Saturn. Winds have various aspects, an important one being its velocity ; another the density of the gas involved; another its energy content or wind energy. Wind is also a great source of transportation for seeds and small birds; with time things can travel thousands of miles in the wind.

A storm surge, storm flood, tidal surge or storm tide is a coastal flood or tsunami-like phenomenon of rising water commonly associated with low pressure weather systems, the severity of which is affected by the shallowness and orientation of the water body relative to storm path, as well as the timing of tides. Most casualties during tropical cyclones occur as the result of storm surges. It is a measure of the rise of water beyond what would be expected by the normal movement related to tides.

Over the past two centuries, tropical cyclones have been responsible for the deaths of about 1.9 million people worldwide. Large areas of standing water caused by flooding lead to infection, as well as contributing to mosquito-borne illnesses. Crowded evacuees in shelters increase the risk of disease propagation. [2] Tropical cyclones significantly interrupt infrastructure, leading to power outages, bridge destruction, and the hampering of reconstruction efforts. [2] [4] On average, the Gulf and east coasts of the United States suffer approximately US $5 billion (1995 US $) in cyclone damage every year. The majority (83%) of tropical cyclone damage is caused by severe hurricanes, category 3 or greater. However, category 3 or greater hurricanes only account for about one-fifth of cyclones that make landfall every year. [5]

Emergency shelter place for people to live temporarily when they cannot live in their previous residence

An emergency shelter is a place for people to live temporarily when they cannot live in their previous residence, similar to homeless shelters. The main difference is that an emergency shelter typically specializes in people fleeing a specific type of situation, such as natural or man-made disasters, domestic violence, or victims of sexual abuse. A more minor difference is that people staying in emergency shelters are more likely to stay all day, except for work, school, or errands, while homeless shelters usually expect people to stay elsewhere during the day, returning only to sleep or eat. Emergency shelters sometimes facilitate support groups, and/or provide meals.

Although cyclones take an enormous toll in lives and personal property, they may be important factors in the precipitation regimes of places they impact, as they may bring much-needed precipitation to otherwise dry regions. [6] Tropical cyclones also help maintain the global heat balance by moving warm, moist tropical air to the middle latitudes and polar regions, [7] and by regulating the thermohaline circulation through upwelling. [8] The storm surge and winds of hurricanes may be destructive to human-made structures, but they also stir up the waters of coastal estuaries, which are typically important fish breeding locales. Tropical cyclone destruction spurs redevelopment, greatly increasing local property values. [9]

Middle latitudes

The middle latitudes of Earth lie between 23°26'22" and 66°33'39" north, and between 23°26'22" and 66°33'39" south. They include Earth's subtropical temperate zones, which lie between the tropics and the polar circles. Weather fronts and extratropical cyclones are usually found in this area, as well as occasional tropical cyclones, which have traveled from their areas of formation closer to the Equator.

Thermohaline circulation A part of the large-scale ocean circulation that is driven by global density gradients created by surface heat and freshwater fluxes

Thermohaline circulation (THC) is a part of the large-scale ocean circulation that is driven by global density gradients created by surface heat and freshwater fluxes. The adjective thermohaline derives from thermo- referring to temperature and -haline referring to salt content, factors which together determine the density of sea water. Wind-driven surface currents travel polewards from the equatorial Atlantic Ocean, cooling en route, and eventually sinking at high latitudes. This dense water then flows into the ocean basins. While the bulk of it upwells in the Southern Ocean, the oldest waters upwell in the North Pacific. Extensive mixing therefore takes place between the ocean basins, reducing differences between them and making the Earth's oceans a global system. On their journey, the water masses transport both energy and mass of substances around the globe. As such, the state of the circulation has a large impact on the climate of the Earth.

Upwelling The replacement by deep water moving upwards of surface water driven offshore by wind

Upwelling is an oceanographic phenomenon that involves wind-driven motion of dense, cooler, and usually nutrient-rich water towards the ocean surface, replacing the warmer, usually nutrient-depleted surface water. The nutrient-rich upwelled water stimulates the growth and reproduction of primary producers such as phytoplankton. Due to the biomass of phytoplankton and presence of cool water in these regions, upwelling zones can be identified by cool sea surface temperatures (SST) and high concentrations of chlorophyll-a.

When hurricanes surge upon shore from the ocean, salt is introduced to many freshwater areas and raises the salinity levels too high for some habitats to withstand. Some are able to cope with the salt and recycle it back into the ocean, but others can not release the extra surface water quickly enough or do not have a large enough freshwater source to replace it. Because of this, some species of plants and vegetation die due to the excess salt. [10] In addition, hurricanes can carry toxins and acids onto shore when they make landfall. The flood water can pick up the toxins from different spills and contaminate the land that it passes over. The toxins are very harmful to the people and animals in the area, as well as the environment around them. The flooding water can also spark many dangerous oil spills. [11]

Salinity The proportion of salt dissolved in a body of water

Salinity is the saltiness or amount of salt dissolved in a body of water, called saline water. This is usually measured in . Salinity is an important factor in determining many aspects of the chemistry of natural waters and of biological processes within it, and is a thermodynamic state variable that, along with temperature and pressure, governs physical characteristics like the density and heat capacity of the water.

Recent windstorm activity, in the United States in particular[ citation needed ], has focused interest in measures that can be used to lower the likelihood of damage to structures. Billions of dollars of damages have resulted from such strong winds and the manner in which structures have been built in the affected areas in the United States. Some building codes address mitigation measures. For example, the Florida Building Code, [12] specifies the type of nail used to secure roof sheathing. [13] The specification was determined by scientific research conducted by Florida International University's International Hurricane Research Center. [14]

United States Federal republic in North America

The United States of America (USA), commonly known as the United States or America, is a country composed of 50 states, a federal district, five major self-governing territories, and various possessions. At 3.8 million square miles, the United States is the world's third or fourth largest country by total area and is slightly smaller than the entire continent of Europe's 3.9 million square miles. With a population of over 327 million people, the U.S. is the third most populous country. The capital is Washington, D.C., and the largest city by population is New York City. Forty-eight states and the capital's federal district are contiguous in North America between Canada and Mexico. The State of Alaska is in the northwest corner of North America, bordered by Canada to the east and across the Bering Strait from Russia to the west. The State of Hawaii is an archipelago in the mid-Pacific Ocean. The U.S. territories are scattered about the Pacific Ocean and the Caribbean Sea, stretching across nine official time zones. The extremely diverse geography, climate, and wildlife of the United States make it one of the world's 17 megadiverse countries.

There have been many lessons learned about individual preparedness since Hurricane Katrina. The biggest responsibility was helping the children of New Orleans. Supplies were sufficient until there was more damage than the hospitals were prepared for. People were afraid that their safety was in danger due to lack of security and support at hospitals. [15]

An important decision in individual preparedness is determining if and when to evacuate an area that will be affected by a tropical cyclone. [16] Tropical cyclone tracking charts allow people to track ongoing systems to form their own opinions regarding where the storms are going and whether or not they need to prepare for the system being tracked, including possible evacuation. This continues to be encouraged by the National Oceanic and Atmospheric Administration and National Hurricane Center. [17] Some agencies provide track storms in their immediate vicinity, [18] while others cover entire ocean basins. One can choose to track one storm per map, use the map until the table is filled, or use one map per season. Some tracking charts have important contact information in case of an emergency or to locate nearby hurricane shelters. [19] Tracking charts allow tropical cyclones to be better understood by the end user. [20] If evacuation is not possible or necessary, other preparedness actions include storing supplies, securing a home against extreme winds and rain, and making plans with others prior to the storm's landfall.

Hurricane preparedness kits usually include drinkable water, sealed pre-prepared meals MRE, first-aid kits, prescription medications in sealed containers, waterproof battery-powered or hand-crank-powered flashlights and radios, a whistle or other sound-signaling device, a multi-tool with a knife, identification and medical cards, any necessary medical records, waterproof bags or portable waterproof containers, and other supplies helpful to a survival situation. If your pets will be with you make sure you include canned or dry food for them as well(any dry food included should be rotated every 2 months). [21] You should also include veterinarian records and proof of vaccinations for all of your pets. [22]

Preparedness also may include having discussed evacuation plans and routes, and informing others of those plans before a disaster occurs.

Evacuation to hurricane shelters is an option of last resort[ citation needed ]. Shelter space is first-come, first-served and only intended preserve human life. Buildings designated as shelters in Florida are required to only have been constructed to meet minimum code requirements applicable at the time of design[ citation needed ]. Some shelters are expected to protect occupants from wind and water but are not expected to provide food, water, sanitation, or bedding. [23]

Based on preparedness of the people in a region, the preparedness level was greatly affected by the salary, race, age, etc. Many people are not prepared for the worst-case scenario, but they should be. Being prepared for a huge disaster is what will ultimately save your life if worse comes to worst. [24]

Hospitals are needed to be prepared in advance for huge natural disasters. Nurses are in high demand when people are in trouble. They need to be prepared for ready for any situation that enters the hospital. After hurricanes such as Katrina and Rita, nurses are needed to be fully capable of any possible scenario. [25]

Home retrofitting

An important decision a homeowner should make is to locate the building outside of range from the coast that is exposed to storm surge. Regardless of protection from the effects of wind, a building can be flooded or destroyed by storm surge waters.

To mitigate the effects of high winds and associated debris impact, the home can be examined out by an experienced hurricane mitigation professional. Many hurricane protection companies offer free consultations as part of their marketing strategy. The State of Florida has taken steps to help its homeowners in the area of hurricane preparedness through its My Safe Florida Home grant program. [26] Qualified homeowners receive a free in-home assessment of their home's hurricane readiness. The state matches funds spent by the homeowner, up to a $5,000 limit.[ citation needed ]

When making these types of home improvements, there are two major areas of focus: the roof and the openings.

Homes may be retrofitted to withstand the extreme conditions of a tropical cyclone. Common modifications include reinforcing gabled roofs, applying additional adhesives to roof shingles, installing hurricane straps and clips to ensure the roof stays in place despite high winds. [27] Hurricane resistant shutters, as well as impact resistant glass may help keep windows closed from driving rain, despite flying debris.

External patio and pool screen enclosures are especially vulnerable during a hurricane. A homeowner who anticipates sustained winds greater than 100 mph may use a razor knife taped to a telescopic pole to cut down the screens from the enclosure's skeleton structure. [28] This will prevent the screens from acting as a sail and pulling down the entire enclosure structure.

Reinforcing garage doors and entry doors is also common practice for hurricane preparing a home. [29] Garage doors may be protected by fabric screens, made of a strong woven fabric, to keep out projectiles and to reinforce the door.

The goal of these mitigation measures and products is to decrease the likelihood of severe damage to a home. There is no guarantee that these measures will safeguard any home against any kind of storm and the projectiles that may come with a storm, but a well-protected home is far more likely to come through a hurricane in better shape than a home that has little or no protection.

Organized preparation

Hurricane mitigation uses policies to make buildings and other infrastructure more resistant to the effects of tropical cyclones. In addition to facilities themselves being at risk, the internal contents of the structures can be damaged as result of exposure to water if the building envelope is breached, usually as a result of the strong winds associated with hurricanes and tropical storms. Although the negative pressure caused by high velocity wind flowing over a building roof can cause the roof to fail with the building envelope intact, [30] broken windows allow the air pressure to rise inside a building, creating an even greater pressure difference, and increasing the likelihood of roof failure. This pressure increase results after an opening, that is, a window or door, is breached after being struck and broken by wind blown debris.

Product certification

Few codes make the use of hurricane mitigation products mandatory[ citation needed ]. As the field is rather new to construction, few standards exist to address uniform testing or product certification of product installations[ citation needed ].

Test facilities

There is no single test standard or facility capable of qualifying the protection of an entire building. The Cyclone Testing Station [32] in Australia can test building systems (e.g., roofs, exterior cladding), and indirectly test entire small buildings with structural loading to simulate wind pressures. In the United States, the test facilities at the FM Global Research Campus includes both direct wind testing of roof components to speeds up to 160 mph (260 km/h), [33] and roof uplift simulation using suction tables per industry standards. [34]

Hurricane simulator

University of Florida's team led by Forrest Masters developed "the world's most powerful portable hurricane simulator, a giant machine capable of reproducing winds in excess of 120 mph (190 km/h) and recreating rain." [35] It consists of eight large fans driven by four diesel engines, with a 5,000-gallon (19,000 litre) water tank to keep the engines cooled. The university is currently designing water-resistant windows, wind-proof tiles and altogether stronger structures. [36] [37]

This machine was used in the MythBusters 2009 season to test the myth that it's better to leave the windows open during a hurricane than closed (the myth was declared Busted).

1979 Atlantic hurricane season hurricane season in the Atlantic Ocean

The 1979 Atlantic hurricane season was the first season to include both male and female names, as well as the common six-year rotating lists of tropical cyclone names. The season officially began on June 1, and lasted until November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. It was slightly below average, with nine systems reaching tropical storm intensity. The first system, an unnumbered tropical depression, developed north of Puerto Rico on June 9. Two days later, Tropical Depression One formed and produced severe flooding in Jamaica, with 40 deaths and about $27 million (1979 USD) in damage. Tropical Storm Ana caused minimal impact in the Lesser Antilles. Hurricane Bob spawned tornadoes and produced minor wind damage along the Gulf Coast of the United States, primarily in Louisiana, while the remnants caused flooding, especially in Indiana. Tropical Storm Claudette caused extensive flooding, due to torrential rainfall. There were two deaths and damaged totaled $750 million.

Hurricane Anita Category 5 Atlantic and Pacific hurricane in 1977

Hurricane Anita was a powerful Atlantic hurricane during an otherwise quiet 1977 Atlantic hurricane season. The first tropical cyclone of the season, Anita developed from a tropical wave on August 29 in the north-central Gulf of Mexico. It tracked westward into an area with conditions favorable for further development, and quickly intensified into a hurricane by late on August 30. Initially, Anita was forecast to strike Texas, though a building ridge turned it to the west-southwest. The hurricane rapidly strengthened to attain peak winds of 175 mph (280 km/h), and on September 2 Anita made landfall in eastern Tamaulipas as a Category 5 hurricane. It quickly weakened as it crossed Mexico, and after briefly redeveloping into a tropical depression in the eastern Pacific Ocean, Anita dissipated on September 4 to the south of the Baja California Peninsula.

2005 Atlantic hurricane season Summary of the relevant tropical storms

The 2005 Atlantic hurricane season was the most active Atlantic hurricane season in recorded history, shattering numerous records. The impact of the season was widespread and catastrophic. Its storms caused an estimated total of 3,960 deaths and approximately $180.7 billion in damage, making it the second costliest season on record, surpassed only by the 2017 season.

Hurricane Kenna Category 5 Pacific hurricane in 2002

Hurricane Kenna was at the time tied as the second-most intense Pacific hurricane to strike the west coast of Mexico. Kenna was the sixteenth tropical depression, thirteenth tropical storm, seventh hurricane, sixth major hurricane, and third Category 5 hurricane of the 2002 Pacific hurricane season. After forming on October 22 to the south of Mexico from a tropical wave, forecasters consistently predicted the storm to strengthen much less than it actually did. Moving into an area of favorable upper-level conditions and warm sea surface temperatures, Kenna quickly strengthened to reach peak winds of 165 mph (270 km/h) as a Category 5 hurricane, on October 25, while located about 255 mi (410 km) southwest of Puerto Vallarta, Jalisco. Weakening as it turned to the northeast, the hurricane made landfall near San Blas, Nayarit as a Category 4 hurricane, with sustained winds of 140 mph (220 km/h), before dissipating on October 26 over the Sierra Madre Occidental mountains.

Hurricane Catarina South Atlantic tropical cyclone of March 2004

Hurricane Catarina was an extremely rare South Atlantic tropical cyclone that hit Southern Brazil in late March 2004. The storm developed out of a stationary cold-core upper-level trough on March 12. Almost a week later, on March 19, a disturbance developed along the trough and traveled towards the east-southeast until March 22 when a ridge stopped the forward motion of the disturbance. The disturbance was in an unusually favorable environment with a slightly below-average wind shear and above-average sea surface temperatures. The combination of the two led to a slow transition from an extratropical cyclone to a subtropical cyclone by March 24. The storm continued to obtain tropical characteristics and became a tropical storm the next day while the winds steadily increased. The storm attained wind speeds of 75 mph (120 km/h)—equivalent to a low-end Category 1 hurricane on the Saffir–Simpson scale—on March 26. At this time it was unofficially named Catarina and was also the first hurricane-strength tropical cyclone ever recorded in the Southern Atlantic Ocean. Unusually favorable conditions persisted and Catarina continued to intensify and was estimated to have peaked with winds of 100 mph (155 km/h) on March 28. The center of the storm made landfall later that day at the time between the cities of Passo de Torres and Balneário Gaivota, Santa Catarina. Catarina rapidly weakened upon landfall and dissipated on the next day.

Hurricane Erin (1995) Category 2 Atlantic hurricane in 1995

Hurricane Erin was the fifth named tropical cyclone and the second hurricane of the unusually active 1995 Atlantic hurricane season. Erin began as a tropical wave off the west coast of Africa on July 22, but the storm crossed most of the Atlantic ocean without developing. On July 31, it developed a closed circulation and became a tropical storm. It made landfall on the central eastern Florida coastline as a Category 1 hurricane on August 2 and again along the Florida Panhandle as a Category 2 hurricane on August 3, causing a moderate amount of damage. The system reached its peak strength of 100 mph (155 km/h) and 973 millibars in central pressure just prior to the second landfall.

Meteorological history of Hurricane Katrina

Hurricane Katrina was an extremely destructive Category 5 hurricane that affected the majority of the Gulf Coast. Its damaging trek began on August 23, 2005 when it originated as Tropical Depression Twelve near the Bahamas. The next day, the tropical depression strengthened to a tropical storm, and was named Katrina; it proceeded to make landfall on the southern tip of the U.S. state of Florida as a minimal hurricane.

1926 Nassau hurricane Category 4 Atlantic hurricane in 1926

The 1926 Nassau hurricane also known as the San Liborio hurricane or The Great Bahamas Hurricane of 1926, in Puerto Rico, was a destructive Category 4 hurricane that affected the Bahamas at peak intensity. Although it weakened considerably before its Florida landfall, it was one of the most severe storms to affect the Bahamian capital Nassau and the island of New Providence in several years until the 1928 Okeechobee hurricane, which occurred just two years later. The storm also delivered flooding rains and loss of crops to the southeastern United States and Florida.

September 1948 Florida hurricane

The September 1948 Florida hurricane was the most intense tropical cyclone to make landfall in the state since the 1935 Labor Day hurricane. The fourth hurricane and third major hurricane of the season, this storm developed from a tropical wave over the Caribbean Sea on September 18. Early the next day, the system strengthened into a hurricane while moving westward. Thereafter, it curved northwestward and continued to deepen. By September 20, the system turned northward and later that day made landfall in Zapata Peninsula, Cuba as a Category 3 hurricane on the modern day Saffir–Simpson hurricane wind scale. Another landfall occurred in Cuba early the next day to the south of Güines. Severe destruction was reported on the island, with winds up to 90 mph (140 km/h) observed in Havana. Over 700 buildings were destroyed. Ten deaths occurred and damage totaled at least $2 million (1948 USD), while other sources estimate "several million dollars."

Effects of tropical cyclones effect of cyclone

The main effects of tropical cyclones include heavy rain, strong wind, large storm surges near landfall, and tornadoes. The destruction from a tropical cyclone, such as a hurricane or tropical storm, depends mainly on its intensity, its size, and its location. Tropical cyclones act to remove forest canopy as well as change the landscape near coastal areas, by moving and reshaping sand dunes and causing extensive erosion along the coast. Even well inland, heavy rainfall can lead to mudslides and landslides in mountainous areas. Their effects can be sensed over time by studying the concentration of the Oxygen-18 isotope within caves within the vicinity of cyclones' paths.

1851 Atlantic hurricane season hurricane season in the Atlantic Ocean

The 1851 Atlantic hurricane season was the first Atlantic hurricane season to be included in the official Atlantic tropical cyclone record. Six known tropical cyclones occurred during the season, the earliest of which formed on June 25 and the latest of which dissipated on October 19. These dates fall within the range of most Atlantic tropical cyclone activity. None of the cyclones existed simultaneously with another. Of the six storms, two only have a single point in their track known.

Effects of Hurricane Katrina in Florida

The effects of Hurricane Katrina in Florida were in both in the southern portion of the state and in the panhandle. After developing on August 23, Katrina made landfall near the border of Broward and Miami-Dade counties with 80 mph (130 km/h) winds on August 25. While it was crossing the state, the hurricane's convection was asymmetrical, primarily located to the south and east of the center. As a result, high rainfall totals occurred in the Miami area, peaking at 16.43 in (417 mm) in Perrine. The rains caused flooding, and the combination of rains and winds downed trees and power lines, leaving 1.45 million people without power. Damage in South Florida was estimated at $523 million (2005 USD), mostly as a result of crop damage. Further south, the hurricane spawned a tornado in the Florida Keys. In the island chain, Katrina dropped heavy rainfall and gusty winds.

1941 Florida hurricane Category 1 Atlantic hurricane in 1941

The 1941 Florida hurricane was a compact but strong tropical cyclone that affected the Bahamas, Florida, and the southeastern United States in October 1941. The fifth known storm of the 1941 Atlantic hurricane season, it was first observed to the north of the Virgin Islands on October 3. The storm tracked generally westward, reaching peak winds of 120 miles per hour (193 km/h) before passing through the Bahamas. After weakening somewhat, the storm later passed across southern Florida with winds of 100 mph (161 km/h). The hurricane then emerged into the Gulf of Mexico as a tropical storm, but regained hurricane intensity and made another landfall along the Florida Panhandle. Turning northeast, it crossed Georgia and South Carolina, and entered the Atlantic Ocean on October 8.

1948 Miami hurricane Category 4 Atlantic hurricane in 1948

The 1948 Miami hurricane(Air Weather Service designation: Fox) caused no fatalities in Florida, despite moving across the Miami area as a hurricane. The ninth tropical storm and fifth hurricane of the 1948 season, the storm developed from a large low pressure area over the northwestern Caribbean Sea on October 3. The storm intensified into a tropical storm early the next day and a hurricane several hours later. Fox then significantly deepened, peaking with winds of 125 mph (205 km/h) early on October 5. Around that time, Fox made landfall in eastern Pinar del Río Province of Cuba. Fox crossed the island and emerged into the Straits of Florida. Late on October 5, the hurricane struck Bahia Honda Key, Florida, with winds of 105 mph (165 km/h) and two hours later, hit Flamingo. Fox emerged into the Atlantic Ocean near Fort Lauderdale early on October 6. The storm moved northeastward and later curved to the east-northeast. Late on October 7, Fox made landfall on Bermuda with winds of 105 mph (165 km/h). Fox weakened over the next several days and later executed a large cyclonic loop. By October 16, it became extratropical while well east-southeast of Newfoundland.

Hurricane Kiko (1989) Category 3 Pacific hurricane in 1989

Hurricane Kiko was one of the strongest tropical cyclones to have hit the eastern coast of Mexico's Baja California peninsula during recorded history. The eleventh named storm of the 1989 Pacific hurricane season, Kiko formed out of a large mesoscale convective system on August 25. Slowly tracking northwestward, the storm rapidly intensified into a hurricane early the next day. Strengthening continued until early August 27, when Kiko reached its peak intensity with winds of 120 mph (195 km/h). The storm turned west at this time, and at around 0600 UTC, the storm made landfall near Punta Arena at the southern tip of Baja California Sur. The hurricane rapidly weakened into a tropical storm later that day and further into a tropical depression by August 28, shortly after entering the Pacific Ocean. The depression persisted for another day while tracking southward, before being absorbed by nearby Tropical Storm Lorena. Though Kiko made landfall as a Category 3 hurricane, its impact was relatively minor. Press reports indicated that 20 homes were destroyed and numerous highways were flooded by torrential rains.

Hurricane Rina Category 3 Atlantic hurricane in 2011

Hurricane Rina was a powerful but slow-moving tropical cyclone that caused minor impacts in the northwestern Caribbean Sea in late October 2011. The seventeenth named storm, seventh hurricane, and fourth major hurricane of the annual hurricane season, Rina developed from a tropical wave in the western Caribbean on October 23. The depression quickly intensified, and was upgraded to Tropical Storm Rina early on the following day. Further strengthening ensued as it tracked west-northwestward, with Rina becoming a hurricane on October 24. The hurricane eventually peaked as a Category 3 hurricane while it moved generally westward on October 25. However, on October 26, Rina weakened substantially and was downgraded to a Category 1 hurricane. Further weakening occurred, with Rina falling to tropical storm intensity on October 27. Rina then made landfall in northern Quintana Roo early the next day. The cyclone degenerated into a remnant low later on October 28 after emerging into the Yucatán Channel. The low dissipated near the western tip of Cuba on October 29.

Hurricane Andrew Category 5 Atlantic hurricane in 1992

Hurricane Andrew was a destructive Category 5 Atlantic hurricane that struck the Bahamas, Florida, and Louisiana in mid-to-late August 1992. It was the most destructive hurricane to ever hit Florida until Hurricane Irma surpassed it 25 years later. It was the strongest in decades and the costliest hurricane to make landfall anywhere in the United States until it was surpassed by Katrina in 2005. Andrew caused major damage in the Bahamas and Louisiana, but the greatest impact was felt in South Florida, where the storm made landfall as a Category 5 hurricane, with sustained wind speeds as high as 165 mph (270 km/h). Passing directly through the city of Homestead in Dade County, Andrew stripped many homes of all but their concrete foundations.

Hurricane Michael was the third-most intense Atlantic hurricane to make landfall in the United States in terms of pressure, behind the 1935 Labor Day hurricane and Hurricane Camille of 1969, as well as the strongest storm in terms of maximum sustained wind speed to strike the contiguous United States since Andrew in 1992. In addition, it was the strongest storm on record in the Florida Panhandle, and was the fourth-strongest landfalling hurricane in the contiguous United States, in terms of wind speed.
