The Beaufort scale is an empirical measure that relates wind speed to observed conditions at sea or on land. Its full name is the Beaufort wind force scale.
The National Hurricane Center (NHC) is the division of the United States' NOAA/National Weather Service responsible for tracking and predicting tropical weather systems between the Prime Meridian and the 140th meridian west poleward to the 30th parallel north in the northeast Pacific Ocean and the 31st parallel north in the northern Atlantic Ocean. The agency, which is co-located with the Miami branch of the National Weather Service, is situated on the campus of Florida International University in University Park, Florida.
Hurricane Fran caused extensive damage in the United States in early September 1996. The sixth named storm, fifth hurricane, and third major hurricane of the 1996 Atlantic hurricane season, Fran developed from a tropical wave near Cape Verde on August 23. Due to nearby Hurricane Edouard, the depression remained disorganized as it tracked westward, though it eventually intensified into Tropical Storm Fran on August 27. While heading west-northwestward, Fran steadily strengthened into a hurricane on August 29, but weakened back to a tropical storm on the following day. On August 31, Fran quickly re-intensified into a hurricane. By September 2, Fran began to parallel the islands of the Bahamas and slowly curved north-northwestward. Early on September 5, Fran peaked as a 120 mph (195 km/h) Category 3 hurricane. Thereafter, Fran weakened slightly, before it made landfall near Cape Fear, North Carolina early on September 6. The storm rapidly weakened inland and was only a tropical depression later that day. Eventually, Fran curved east-northeastward and transitioned into an extratropical cyclone over Ontario early on September 9.
Hurricane Donna, known in Puerto Rico as Hurricane San Lorenzo, was the strongest hurricane of the 1960 Atlantic hurricane season, and caused severe damage to the Lesser Antilles, the Greater Antilles, and the East Coast of the United States, especially Florida, in August–September. The fifth tropical cyclone, third hurricane, and first major hurricane of the season, Donna developed south of Cape Verde on August 29, spawned by a tropical wave to which 63 deaths from a plane crash in Senegal were attributed. The depression strengthened into Tropical Storm Donna by the following day. Donna moved west-northwestward at roughly 20 mph (32 km/h) and by September 1, it reached hurricane status. Over the next three days, Donna deepened significantly and reached maximum sustained winds of 130 mph (210 km/h) on September 4. Thereafter, it maintained intensity as it struck the Lesser Antilles later that day. On Sint Maarten, the storm left a quarter of the island's population homeless and killed seven people. An additional five deaths were reported in Anguilla, and there were seven other fatalities throughout the Virgin Islands. In Puerto Rico, severe flash flooding led to 107 fatalities, 85 of them in Humacao alone.
Hurricane Iniki was the most powerful hurricane to strike the U.S. state of Hawaii in recorded history. Forming on September 5, 1992, during the strong 1990–1995 El Niño, Iniki was one of eleven Central Pacific tropical cyclones during that season. It attained tropical storm status on September 8 and further intensified into a hurricane the next day. After turning north, Iniki struck the island of Kauaʻi on September 11 at peak intensity; it had winds of 145 mph and reached Category 4 status on the Saffir–Simpson hurricane scale. It had recorded wind gusts of 225 mph as evidenced by an anemometer that was found blown into the forest during clean up. It was the first hurricane to hit the state since Hurricane Iwa in the 1982 season, and the first major hurricane since Hurricane Dot in 1959. Iniki dissipated on September 13 about halfway between Hawaii and Alaska.
Tropical cyclone warnings and watches are alerts issued by national weather forecasting bodies to coastal areas threatened by the imminent approach of a tropical cyclone of tropical storm or hurricane intensity. They are notices to the local population and civil authorities to make appropriate preparation for the cyclone, including evacuation of vulnerable areas where necessary. It is important that interests throughout the area of an alert make preparations to protect life and property, and do not disregard it on the strength of the detailed forecast track. Tropical cyclones are not points, and forecasting their track remains an uncertain science.
Hurricane Frances was the second most intense tropical cyclone in the Atlantic during 2004 and proved to be very destructive in Florida. It was the sixth named storm, the fourth hurricane, and the third major hurricane of the 2004 Atlantic hurricane season. The system crossed the open Atlantic in late August, moving to the north of the Lesser Antilles while strengthening. Its outer bands struck Puerto Rico and the British Virgin Islands while passing north of the Caribbean Sea. The storm's maximum sustained wind peaked at 145 mph (233 km/h), achieving Category 4 on the Saffir-Simpson Hurricane Scale. As the system's forward motion slowed, the eye passed over San Salvador Island and very close to Cat Island in the Bahamas. Frances was the first hurricane to impact the entire Bahamian archipelago since 1928 and almost completely destroyed their agricultural economy.
Hurricane Allen was a rare and extremely powerful Cape Verde hurricane that affected the Caribbean, eastern and northern Mexico, and southern Texas in August 1980. The first named storm and second tropical cyclone of the 1980 Atlantic hurricane season, it was the fifth most intense Atlantic hurricane on record in terms of barometric pressure, behind Hurricane Rita, the 1935 Labor Day hurricane, Hurricane Gilbert, and Hurricane Wilma. It was one of the few hurricanes to reach Category 5 status on the Saffir–Simpson Hurricane Scale on three occasions, and spent more time as a Category 5 than all but two other Atlantic hurricanes. Allen is the only hurricane in the recorded history of the Atlantic basin to achieve sustained winds of 190 mph (305 km/h), thus making it the strongest Atlantic hurricane by wind speed. Until Hurricane Patricia in 2015, these were also the highest sustained winds in the Western Hemisphere.
Hurricane Jeanne was a Category 3 hurricane that struck the Caribbean and the Eastern United States in September 2004. It was the deadliest hurricane in the Atlantic basin since Mitch in 1998. It was the tenth named storm, the seventh hurricane, and the fifth major hurricane of the season, as well as the third hurricane and fourth named storm of the season to make landfall in Florida. After wreaking havoc on Hispaniola, Jeanne struggled to reorganize, eventually strengthening and performing a complete loop over the open Atlantic. It headed westwards, strengthening into a Category 3 hurricane and passing over the islands of Great Abaco and Grand Bahama in the Bahamas on September 25. Jeanne made landfall later in the day in Florida just two miles from where Hurricane Frances had struck a mere three weeks earlier.
Hurricane Cleo was the strongest tropical cyclone of the 1964 Atlantic hurricane season. It was the third named storm, first hurricane, and first major hurricane of the season. Cleo was one of the longest-lived storms of the season. This compact yet powerful hurricane travelled through the Caribbean Sea and later hit Florida before moving offshore Georgia into the Carolinas, killing 156 people and causing roughly $187 million in damage. Major damage was seen as far north as east-central Florida, with the heaviest rains falling along the immediate coast of the Southeast United States into southeast Virginia.
Hurricane Luis was a long lived and powerful Category 4 hurricane. It was the strongest hurricane to make landfall, and the third-most intense hurricane recorded during the 1995 Atlantic hurricane season. The storm, along with Humberto, Iris, and Karen, was one of four simultaneous tropical systems in the Atlantic basin.
The 1919 Florida Keys hurricane was a massive and damaging tropical cyclone that swept across areas of the northern Caribbean Sea and the United States Gulf Coast in September 1919. Remaining an intense Atlantic hurricane throughout much of its existence, the storm's slow-movement and sheer size prolonged and enlarged the scope of the hurricane's effects, making it one of the deadliest hurricanes in United States history. Impacts were largely concentrated around the Florida Keys and South Texas areas, though lesser but nonetheless significant effects were felt in Cuba and other areas of the United States Gulf Coast. The hurricanes peak strength in Dry Tortugas in the lower Florida keys, also made it one of the most powerful Atlantic hurricanes to make landfall in the United States.
Hurricane Ophelia was the fifteenth named tropical cyclone and the eighth hurricane of the 2005 Atlantic hurricane season. It was a long-lived storm that was most memorable for its very erratic and extremely slow track off the East Coast of the United States, alternating several times between tropical storm and hurricane intensity.
Tropical cyclones are ranked on one of five tropical cyclone intensity scales, according to their maximum sustained winds and which tropical cyclone basin(s) they are located in. Only a few scales of classifications are used officially by the meteorological agencies monitoring the tropical cyclones, but other scales also exist, such as accumulated cyclone energy, the Power Dissipation Index, the Integrated Kinetic Energy Index, and the Hurricane Severity Index.
Hurricane Juliette was a long-lasting Category 4 hurricane in the 2001 Pacific hurricane season. It caused 12 deaths and $400 million in damage when it hit Baja California in late September.
Hurricane Rick was the second-latest hurricane ever to make landfall in Mexico. The eighteenth named storm, ninth and final hurricane of the 1997 Pacific hurricane season, Rick was a short-lived Category 2 hurricane on the Saffir-Simpson Hurricane Scale that weakened before making landfall in Mexico on November 10. It hit almost a month after the more powerful Hurricane Pauline made landfall in the same country. Most of the damage associated with Pauline was exacerbated by the weaker Rick, which struck during rebuilding efforts.
Hurricane Hanna was a moderately powerful but deadly tropical cyclone that caused extensive damage across the Western Atlantic, particularly in the Turks and Caicos Islands and the East Coast of the United States. The eighth named storm and fourth hurricane of the 2008 Atlantic hurricane season. It formed east-northeast of the northern Leeward Islands on August 28. Initially, the storm struggled to intensify due to moderate wind shear as it moved westwards towards the Bahamas. By August 31, Hanna had drifted southwards and began intensifying while over the Bahamas; it attained its peak intensity as a Category 1 hurricane while over the Turks and Caicos Islands. Due to the outflow of the nearby Hurricane Gustav, Hanna weakened back into a tropical storm the next day as it began to drift northwestwards towards the Southeastern United States. The storm struck Myrtle Beach, South Carolina, before moving up the Eastern Seaboard to become an extratropical cyclone as it moved by New England into Atlantic Canada early on September 7. The system raced across the North Atlantic, sweeping west of Great Britain on September 10 before turning north and becoming absorbed by a stronger extratropical cyclone between Iceland and Greenland late on September 12.
Hurricane Kyle was a Category 1 hurricane that caused heavy rain and flooding in Puerto Rico in its formative stage and brought hurricane-force winds to Nova Scotia while extratropical. The eleventh tropical storm and sixth hurricane of the 2008 Atlantic hurricane season, Kyle formed from a strong tropical disturbance that tracked across the northeastern Caribbean Sea in the third week of September. As a low pressure area, it moved slowly across Puerto Rico and Hispaniola, dumping torrential rains across those islands.

Hurricane Ophelia was regarded as the worst storm to affect Ireland in 50 years, and was also the easternmost Atlantic major hurricane on record. The tenth and final consecutive hurricane and the sixth major hurricane of the very active 2017 Atlantic hurricane season, Ophelia had non-tropical origins from a decaying cold front on 6 October. Located within a favorable environment, the storm steadily strengthened over the next two days, drifting north and then southeastwards before becoming a hurricane on 11 October. After becoming a Category 2 hurricane and fluctuating in intensity for a day, Ophelia intensified into a major hurricane on 14 October south of the Azores, brushing the archipelago with high winds and heavy rainfall. Shortly after achieving peak intensity, Ophelia began weakening as it accelerated over progressively colder waters to its northeast towards Ireland and Great Britain. Completing an extratropical transition early on 16 October, Ophelia became the second storm of the 2017–18 European windstorm season. Early on 17 October, the cyclone crossed the North Sea and struck western Norway, with wind gusts up to 70 kilometres per hour (43 mph) in Rogaland county, before weakening during the evening of 17 October. The system then moved across Scandinavia, before dissipating over Norway on the next day.
