Tropical Storm Georgette was a short-lived tropical storm that struck the Baja California Sur in September 2010. Georgette originated from an area of disturbed weather over the eastern Pacific on September 20. The next day, the system was upgraded into a tropical storm a short distance south of Baja California Sur. As the storm moved over the peninsula, it weakened to a tropical depression. It continued north and as such made landfall on mainland Mexico on September 22. Georgette dissipated early the next day while located inland over Sonora. Although officials noted the threat for heavy rainfall across northwest Mexico and Baja California, damage was minimal and no deaths were reported in the country. However, remnant moisture moved into New Mexico, producing flooding that killed one person.
Baja California Sur, officially the Estado Libre y Soberano de Baja California Sur, is the second-smallest Mexican state by population and the 31st admitted state of the 31 states which, with Mexico City, make up the 32 Federal Entities of Mexico.
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 or squalls. 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".
Sonora, officially Estado Libre y Soberano de Sonora, is one of 31 states that, with Mexico City, comprise the 32 federal entities of United Mexican States. It is divided into 72 municipalities; the capital city is Hermosillo. Sonora is bordered by the states of Chihuahua to the east, Baja California to the northwest and Sinaloa to the south. To the north, it shares the U.S.–Mexico border primarily with the state of Arizona with a small length with New Mexico, and on the west has a significant share of the coastline of the Gulf of California.
The origins of Tropical Storm Georgette were from a tropical wave that moved off the west coast of Africa on September 1. Lacking organization, the wave was difficult to track as it moved across the Atlantic basin. Convection eventually increased on September 7, as the system approached the Lesser Antilles. On September 14, Hurricane Karl developed from the northern portion of the system over the western Caribbean Sea; however, the southern portion of the wave crossed northern Central America and entered the Pacific Ocean on September 17. The area of disturbed weather was first mentioned on the National Hurricane Center (NHC) around that time, but signification development was initially not anticipated. Wind shear was forecast to decrease slightly; however, and based on this the NHC gave the system a medium chance of undergoing tropical cyclogenesis during the next two days.
A tropical wave, in and around the Atlantic Ocean, is a type of atmospheric trough, an elongated area of relatively low air pressure, oriented north to south, which moves from east to west across the tropics, causing areas of cloudiness and thunderstorms. Tropical waves form in the easterly flow along the equatorward side of the subtropical ridge or belt of high air pressure which lies north and south of the Intertropical Convergence Zone (ITCZ). Tropical waves are generally carried westward by the prevailing easterly winds along the tropics and subtropics near the equator. They can lead to the formation of tropical cyclones in the north Atlantic and northeastern Pacific basins. A tropical wave study is aided by Hovmöller diagrams, a graph of meteorological data.
Africa is the world's second largest and second most-populous continent, being behind Asia in both categories. At about 30.3 million km2 including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area. With 1.2 billion people as of 2016, it accounts for about 16% of the world's human population. The continent is surrounded by the Mediterranean Sea to the north, the Isthmus of Suez and the Red Sea to the northeast, the Indian Ocean to the southeast and the Atlantic Ocean to the west. The continent includes Madagascar and various archipelagos. It contains 54 fully recognised sovereign states (countries), nine territories and two de facto independent states with limited or no recognition. The majority of the continent and its countries are in the Northern Hemisphere, with a substantial portion and number of countries in the Southern Hemisphere.
Atmospheric convection is the result of a parcel-environment instability, or temperature difference layer in the atmosphere. Different lapse rates within dry and moist air masses lead to instability. Mixing of air during the day which expands the height of the planetary boundary layer leads to increased winds, cumulus cloud development, and decreased surface dew points. Moist convection leads to thunderstorm development, which is often responsible for severe weather throughout the world. Special threats from thunderstorms include hail, downbursts, and tornadoes.
Gradual development took place as convection consolidated around the center of circulation while located west of Sonora. During the afternoon of September 20, an area of low pressure developed within the system, prompting the NHC to classify it as a tropical depression. At this time, the depression was situated roughly 240 mi (390 km) south-southeast of Cabo San Lucas. Situated along the western edge of a subtropical ridge, the system was steered towards the north-northwest throughout its existence.
Atmospheric circulation is the large-scale movement of air, and together with ocean circulation is the means by which thermal energy is redistributed on the surface of the Earth.
Cabo San Lucas, or simply Cabo, is a resort city at the southern tip of the Baja California Peninsula, in the Mexican state of Baja California Sur. As of 2015, the population of the city was 81,111 inhabitants. Cabo San Lucas together with San José del Cabo is known as Los Cabos. Together they form a metropolitan area of 305,983 inhabitants.
Within hours of becoming a depression on September 20, strong wind shear caused convection to diminish. However, data from an ASCAT scatterometer pass revealed that the system attained gale-force winds, resulting in the depression being upgraded to a tropical storm on 0000 UTC September 21. Operationally, the first advisory on storm was not issued until 1200 UTC, where it was named Georgette. Meanwhile, thunderstorm activity increased near the center of the storm. Little change took place throughout the day as the storm approached Baja California Sur. Around 1800 UTC, Georgette made landfall near San Jose del Cabo with winds of 40 mph (65 km/h). Additionally, a barometric pressure of 999 mbar (hPa; 29.5 inHg) was measured. Shortly before entering the Gulf of California, Georgette weakened to a tropical depression. Maintaining winds of 35 mph (55 km/h), the storm later made a second landfall near San Carlos in Sonora. Shortly after moving inland, the low-level circulation dissipated over the mountains of western Mexico.
A scatterometer or diffusionmeter is a scientific instrument to measure the return of a beam of light or radar waves scattered by diffusion in a medium such as air. Diffusionmeters using visible light are found in airports or along roads to measure horizontal visibility. Radar scatterometers use radio or microwaves to determine the normalized radar cross section of a surface. They are often mounted on weather satellites to find wind speed and direction, and are used in industries to analyze the roughness of surfaces.
Coordinated Universal Time is the primary time standard by which the world regulates clocks and time. It is within about 1 second of mean solar time at 0° longitude, and is not adjusted for daylight saving time. In some countries where English is spoken, the term Greenwich Mean Time (GMT) is often used as a synonym for UTC and predates UTC by nearly 300 years.
The bar is a metric unit of pressure, but is not approved as part of the International System of Units (SI). It is defined as exactly equal to 100,000 Pa, which is slightly less than the current average atmospheric pressure on Earth at sea level.
Prior to the arrival of Georgette, the Mexican government issued a tropical storm warning for extreme southern Baja California Sur., mm) of rainfall, especially over the higher terrain. The forecasters also noted potential for deadly flooding and mudslides. Officials evacuated over 1,000 families from floodplains and opened four shelters in Los Cabos.but was dropped when Georgette moved inland. Officials warned rural areas in Baja California Sur of heavy rain and high wind. Forecasters at the NHC noted the potential for up to 10 in (25
Rain is liquid water in the form of droplets that have condensed from atmospheric water vapor and then become heavy enough to fall under gravity. Rain is a major component of the water cycle and is responsible for depositing most of the fresh water on the Earth. It provides suitable conditions for many types of ecosystems, as well as water for hydroelectric power plants and crop irrigation.
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: velocity ; the density of the gas involved; energy content or wind energy. Wind is also an important means of transportation for seeds and small birds; with time things can travel thousands of miles in the wind.
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.
In Sonora, the state's civil protection committee placed the south portion of the state under an "orange" alert,and a "red" alert soon after; the alert was lifted that same evening, after Georgette moved inland. A total of 52 shelters were opened in the Cajeme municipality. In Guaymas, 300 people from the city and surrounding areas were placed in shelters; 250 more people sought shelter from Georgette in Empalme. Schools in Bahía Kino and coastal areas of the Hermosillo Municipality suspended classes as a precaution. Classes resumed statewide on September 23.
Cajeme is one of the municipalities of the northwestern state of Sonora, Mexico. It is named after Cajemé, a Yaqui leader. The municipality has an area of 3,312.05 km² and with a population of 433,050 inhabitants as of 2015.
Empalme is a city surrounded by a municipality located on the south-central coast of the Mexican state of Sonora. According to the 2005 census the population of the city was 40,630 inhabitants, while the municipality, which has an area of 708.53 km², reported 50,663 inhabitants. Except for its coastline on the Gulf of California, the municipality is entirely surrounded by the much larger municipality of Guaymas.
Bahía de Kino is a town in the Mexican state of Sonora, Hermosillo (municipality), on the Sea of Cortez ; it was named after Eusebio Kino. The name also applies to the adjacent bay between Tiburón Island and Punta San Nicolás, Sonora. The names Bahía de Kino, Bahía Kino and Kino Bay are used interchangeably.
Georgette caused the heaviest rains on Baja California Sur in the last 15 years, leaving many people homeless. 5.9 in (150 mm) fell in Todos Santos. Throughout Sonora, rainfall up to 4.7 in (120 mm) triggered flooding that damaged 220 homes. Georgette caused 2.61 in (66 mm) of rainfall in Guaymas Flooding was reported in several places (Empalme, Etchojoa, Navojoa, Guaymas, Los Mochis), causing 500,000 people to be evacuated. Heavy runoff caused inflows of 18,000 cu ft/s (510 m3/s) into El Novillo Dam, forcing the Comisión Nacional del Agua, the local water authorities, to release water from the dam.Georgette also produced high waves. The tropical cyclone worsened Mexico's flooding problem which started when Hurricane Karl made landfall several days earlier. A peak rainfall total of
Moisture from the system combined with an approaching trough to produce heavy rainfall and thunderstorms across New Mexico. A total of 6.42 in (163 mm) was reported in Gladstone. The rains caused flooding that killed a person along the Rio Grande near Carnuel.
Hurricane Nora was only the third tropical cyclone on record to reach Arizona as a tropical storm, and one of the rare cyclones to make landfall in Baja California. Nora was the fourteenth named tropical cyclone and seventh hurricane of the 1997 Pacific hurricane season. The September storm formed off the Pacific coast of Mexico, and aided by waters warmed by the 1997–98 El Niño event, eventually peaked at Category 4 intensity on the Saffir–Simpson hurricane scale.
Hurricane Marty was the deadliest tropical cyclone of the 2003 Pacific hurricane season. Forming on September 18, it became the 13th tropical storm and fourth hurricane of the year. The storm moved generally northwestward and steadily intensified despite only a marginally favorable environment for development, and became a Category 2 hurricane before making two landfalls on the Baja California peninsula and mainland Mexico.
Hurricane Javier was a very wet tropical cyclone whose remnants brought above-average rainfall totals across the western United States in September 2004. Javier was the tenth named storm and the sixth and final hurricane of the 2004 Pacific hurricane season. Javier was also the strongest hurricane of the 2004 season, with 150 mph (240 km/h) winds and a central pressure of 930 millibars. However, because of high wind shear in the East Pacific, Javier weakened rapidly before making landfall in Baja California as a tropical depression. The remnants of the storm then continued moving northeast through the Southwestern United States. Javier caused no direct fatalities, and the damage in Mexico and the United States was minimal.
Hurricane John was the eleventh named storm, seventh hurricane, and fifth major hurricane of the 2006 Pacific hurricane season. Hurricane John developed on August 28 from a tropical wave to the south of Mexico. Favorable conditions allowed the storm to intensify quickly, and it attained peak winds of 130 mph (210 km/h) on August 30. Eyewall replacement cycles and land interaction with western Mexico weakened the hurricane, and John made landfall on southeastern Baja California Sur with winds of 110 mph (175 km/h) on September 1. It slowly weakened as it moved northwestward through the Baja California peninsula, and dissipated on September 4. Moisture from the remnants of the storm entered the southwest United States.
Hurricane Isis was the only hurricane to make landfall during the 1998 Pacific hurricane season. The ninth tropical storm and sixth hurricane of the season, Isis developed on September 1 from an interaction between a tropical wave and a large surface circulation to the southwest of Mexico. It moved northward, striking the extreme southeastern portion of the Baja California peninsula before attaining hurricane status in the Gulf of California. Isis made landfall at Topolobampo in the Mexican state of Sinaloa on September 3, and quickly lost its low-level circulation. The remnants persisted for several days before dissipating over the U.S. state of Idaho on September 8.
Hurricane Lester was the first Pacific tropical cyclone to enter the United States as a tropical storm since 1967. The twelfth named storm and seventh hurricane of the 1992 Pacific hurricane season, Lester formed on August 20 from a tropical wave southwest of Mexico. The tropical storm moved generally northwestward while steadily intensifying. After turning to the north, approaching the Mexican coast, Lester attained hurricane status. The hurricane reached peak winds of 85 mph (140 km/h) before making landfall on west-central Baja California. The system weakened while moving across the peninsula and then over northwestern Mexico. Not long after entering Arizona, Lester weakened to a tropical depression, and degenerated into an extratropical low on August 24, 1992, over New Mexico. The storm's remnants later merged with the remnants of Hurricane Andrew and another frontal system on August 29.
Tropical Storm Julio was a tropical storm that made landfall on the southern tip of Baja California Sur in August 2008. The tenth named storm of the 2008 Pacific hurricane season, it developed from a tropical wave on August 23 off the coast of Mexico. It moved parallel to the coast, reaching peak winds of 50 mph (85 km/h) before moving ashore and weakening. On August 26 it dissipated in the Gulf of California. Julio was the third tropical cyclone to make landfall in the Pacific Ocean basin during the season, after Tropical Storm Alma, which struck Nicaragua in May, and Tropical Depression Five-E, which moved ashore along southwestern Mexico in July. The storm brought locally heavy rainfall to southern Baja California, killing one person and leaving several towns isolated. Moisture from Julio reached Arizona, producing thunderstorms, including one which damaged ten small planes in Chandler.
Hurricane Norbert is tied with Hurricane Jimena as the strongest tropical cyclone to strike the west coast of Baja California Sur in recorded history. The fifteenth named storm, seventh hurricane, and second major hurricane of the 2008 hurricane season, Norbert originated as a tropical depression from a tropical wave south of Acapulco on October 3. Strong wind shear initially prevented much development, but the cyclone encountered a more favorable environment as it moved westward. On October 5, the National Hurricane Center (NHC) upgraded the depression to Tropical Storm Norbert, and the system intensified further to attain hurricane intensity by October 6. After undergoing a period of rapid deepening, Norbert reached its peak intensity as a Category 4 on the Saffir–Simpson hurricane wind scale, with maximum sustained winds of 135 mph (215 km/h) and a minimum barometric pressure of 945 mbar. As the cyclone rounded the western periphery of a subtropical ridge over Mexico, it began an eyewall replacement cycle which led to steady weakening. Completing this cycle and briefly reintensifying into a major hurricane, a Category 3 or higher on the Saffir–Simpson hurricane wind scale, Norbert moved ashore Baja California Sur as a Category 2 hurricane late on October 11. After a second landfall at a weaker intensity the following day, the system quickly weakened over land and dissipated that afternoon.
Tropical Storm Lowell was a moderate tropical storm that developed during the 2008 Pacific hurricane season. The fourteenth tropical cyclone and thirteen named storm of the season, Lowell formed out of a western side of a trough on September 6. It quickly intensified into Tropical Storm Lowell, peaking as a moderate tropical storm. It pass directly over Socorro Island and began a weakening trend. It weakened into depression before landfall in Baja California Sur and dissipated before striking Sonora. It later joined with a frontal boundary and Hurricane Ike which caused severe damage as far inland as Chicago. In all, the storm had caused 6 deaths and $15.5 million damage.
Hurricane Jimena was the second-strongest hurricane of the 2009 Pacific hurricane season, and tied with Hurricane Norbert as the strongest tropical cyclone to make landfall on western portion of the Baja California Peninsula. Forming from a tropical wave late on August 28, 2009, off of Mexico's Pacific coast, the system rapidly intensified into a Category 2 hurricane on the next day. Two days after developing, Jimena strengthened into a Category 4 hurricane. After peaking close to Category 5 intensity on September 1, it encountered cold water and began to weaken. When the hurricane made landfall on the Baja California Peninsula on September 3, it was only a Category 2 hurricane. On the next day, the tropical cyclone entered the Gulf of California, though the storm weakened into a remnant low after looping back eastward towards Baja California. The storm's remnants drifted westward into the Pacific afterward, before dissipating on September 8.
Tropical Storm Patricia was a short-lived tropical cyclone that briefly affected parts of Baja California Sur before rapidly degenerating over water. Developing from a tropical wave that traversed the Atlantic Ocean during September 2009, Patricia was first classified as a tropical depression on October 11 several hundred miles south of the Baja California Peninsula. The system quickly intensified into a tropical storm as it tracked in a general northward direction. By October 12, Patricia attained its peak intensity with winds of 60 mph (95 km/h) and a minimum barometric pressure of 996 mbar. The following day, increasing wind shear and unfavorable conditions caused the storm to rapidly weaken. By the morning of October 14, Patricia had degenerated into a non-convective remnant low pressure area near the southern coastline of Baja California Sur. The remnants of the storm persisted until October 15, at which time they dissipated over open waters.
Hurricane Odile is tied for the most intense landfalling tropical cyclone in the Baja California Peninsula during the satellite era. Sweeping across the peninsula in September 2014, Odile inflicted widespread damage, particularly in the state of Baja California Sur, in addition to causing lesser impacts on the Mexican mainland and Southwestern United States. The precursor to Odile developed into a tropical depression south of Mexico on September 10 and quickly reached tropical storm strength. After meandering for several days, Odile began to track northwestward, intensifying to hurricane status before rapidly reaching its Category 4 hurricane peak intensity on September 14. The cyclone slightly weakened before making landfall near Cabo San Lucas with winds of 125 mph (205 km/h). Odile gradually weakened as it tracked across the length of the Baja California Peninsula, briefly crossing into the Gulf of California before degenerating into a remnant system on September 17. These remnants tracked northeastward across the Southwestern United States before they were no longer identifiable on September 19.
Hurricane Blanca was the earliest recorded tropical cyclone to make landfall in Baja California in any given year. Forming as a tropical depression on May 31, Blanca initially struggled to organize due to strong wind shear. However, once this abated, the system took advantage of high sea surface temperatures and ample moisture. After becoming a tropical storm on June 1, Blanca rapidly intensified on June 2–3, becoming a powerful Category 4 hurricane on the Saffir–Simpson hurricane wind scale; maximum sustained winds reached 145 mph (230 km/h) at this time. The hurricane's slow motion resulted in tremendous upwelling of cooler water, resulting in a period of weakening. Blanca gradually recovered from this and briefly regained Category 4 status on June 6 as it moved generally northwest toward the Baja California peninsula. Cooler waters and increased shear again prompted weakening on June 7 and the system struck Baja California Sur on June 8 as a weak tropical storm. It quickly degraded to a depression and dissipated early the next day.
Hurricane Newton was the first hurricane to make landfall on the Baja California Peninsula since Odile in 2014. The fifteenth named storm and the ninth hurricane of the 2016 Pacific hurricane season, Newton formed as a tropical depression out of an area of low pressure off of the coast of Mexico on September 4. Despite only moderately favorable conditions, the storm quickly intensified while moving north and became a hurricane roughly a day after being designated. Attaining peak intensity early on September 6, Newton then proceeded to make landfall on the Baja California Peninsula shortly afterwards. It quickly weakened and degenerated into a remnant low on September 7, before dissipating the next day.
Tropical Storm Lidia was a large tropical cyclone that produced flooding in Baja California Peninsula and parts of western Mexico. The fourteenth tropical cyclone and twelfth named storm of the 2017 Pacific hurricane season, Lidia developed from a large area of disturbed weather west of the Pacific Coast of Mexico on August 31. The storm intensified while moving generally northward or northwestward, peaking with maximum sustained winds of 65 mph (100 km/h) later that day. On September 1, Lidia made landfall in Mexico near Puerto Chale, Baja California Sur, at peak intensity. The storm weakened while traversing the peninsula, ultimately emerging over the Pacific Ocean on September 3, where the storm degenerated into a remnant low. The system brought thunderstorms and wind gusts to Southern California, before dissipating on September 4.
Tropical Depression Nineteen-E was a weak yet very costly tropical cyclone that caused significant flooding throughout Northwestern Mexico and several states within the United States in September 2018. The storm was also the first known tropical cyclone to form over the Gulf of California. Nineteen-E originated from a tropical wave that left the west coast of Africa on August 29 to 30. It continued westward, crossed over Central America, and entered the northeastern Pacific Ocean by September 7. It then meandered to the southwest of Mexico for the next several days as it interacted with a mid-to-upper level trough. The National Hurricane Center (NHC) continued to track the disturbance for the next several days as it traveled northward. A surface trough developed over the Baja California peninsula on September 18. Despite disorganization and having close proximity to land, the disturbance developed into a tropical depression in the Gulf of California on September 19, after having developed a circulation center and more concentrated convection. The system peaked with maximum sustained winds of 35 mph (55 km/h) and a minimum central pressure of 1002 mbar.
Hurricane Rosa brought widespread flooding to northwestern Mexico and the Southwestern United States in late September 2018, and was the first tropical cyclone to make landfall in Baja California since Nora in 1997. The seventeenth named storm, tenth hurricane, and seventh major hurricane of the 2018 Pacific hurricane season, Rosa originated from an Atlantic tropical wave that crossed the West African coast on September 6. The wave proceeded westward across the Atlantic, traversing Central America before entering the Gulf of Tehuantepec on September 22. There, the weather system acquired cyclonic features and became a tropical storm on September 25. Within a favorable atmosphere, Rosa entered a period of rapid intensification on September 27, peaking as a Category 4 hurricane with maximum sustained winds of 150 mph a day later. Over the next few days, Rosa turned north and then northeast while steadily weakening, making landfall in Baja California as a tropical depression on October 2. After crossing over into the Gulf of California, the remnant system split apart and merged with an upper-level low off the coast of California by October 3.
Hurricane Sergio was a powerful and long-lived tropical cyclone that affected the Baja California Peninsula as a tropical storm and caused significant flooding throughout southern Texas in early October 2018. Sergio became the eighth Category 4 hurricane in the East Pacific for 2018, breaking the old record of seven set in 2015. The twentieth named storm, eleventh hurricane, and ninth major hurricane of the season, Sergio originated from a system that was located over northwestern South America on September 24. The National Hurricane Center monitored the disturbance for several days as the system organized into a tropical storm on September 29. Sergio gradually strengthened for the next couple of days as it traveled west-southwestward, becoming a hurricane on October 2. The storm then turned towards the northwest as it underwent rapid intensification and an eyewall replacement cycle, before peaking as a Category 4 hurricane on October 4, with maximum sustained winds of 140 mph (220 km/h). The hurricane maintained peak intensity for 12 hours before undergoing a second eyewall replacement and turning towards the southwest. The system then began another period of intensification, achieving a secondary peak with winds of 125 mph (205 km/h) on October 6. The next day, Sergio began a third eyewall replacement cycle, falling below major hurricane strength. At the same time, the system unexpectedly assumed some annular characteristics. Over the next few days, the cyclone curved from the southwest to the northeast, weakening into a tropical storm on October 9. Sergio made landfall as a tropical storm on October 12 on the Baja California Peninsula, and later in northwestern Mexico as a tropical depression before dissipating early on October 13.
Hurricane Lorena was a strong tropical cyclone that brought heavy rainfall, flooding, and mudslides to Southwestern Mexico and the Baja California Peninsula in September 2019. Lorena was the thirteenth named storm and seventh hurricane of 2019 Pacific hurricane season. Lorena formed from the stronger of two disturbances off the coast of Mexico. The disturbance closest to Mexico became Tropical Storm Lorena, while the other disturbance became Tropical Storm Mario. Lorena strengthened in a favorable environment, and made landfall as a 75 mph Category 1 hurricane in southwestern Mexico on September 18th, but weakened back to a tropical storm due to land interaction. However, after moving back over water between Baja California Sur and mainland Mexico, Lorena re-strengthened into a hurricane, and reached its peak intensity with 85 mph winds and a minimum barometric pressure of 986 millibars. Lorena made a second landfall on Baja California Sur, and quickly weakened thereafter. Lorena degenerated to a remnant low over the Gulf of California. The remnant low moved inland over Mexico and quickly dissipated.
