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.

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.
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.
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.
Prior to the arrival of Georgette, the Mexican government issued a tropical storm warning for extreme southern Baja California Sur., 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 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.
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.
Georgette caused the heaviest rains on Baja California Sur in the last 15 years, leaving many people homeless. 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 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.
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.
The name Georgette has been used for ten tropical cyclones in the Eastern Pacific Ocean.

Tropical Depression Nineteen-E was a weak and short-lived tropical cyclone that caused flooding throughout Northwestern Mexico and several states within the United States. Nineteen-E originated from a tropical wave that left the west coast of Africa on August 29 to 30, 2018. 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 (29.59 inHg).
One day after forming, the depression quickly deteriorated and dissipated after making landfall in Sonora. Overall, the depression affected eleven Mexican states, with torrential rainfall and flooding ensuing in Baja California Sur, Sinaloa, and Sonora. Thirteen individuals were killed in Chihuahua, Sinaloa, and Sonora, and over $40 million USD in agricultural losses were recorded. Excessive rainfall led to the inundation of at least 300,000 structures in Sinaloa. Flood damage there is estimated to be in the hundreds of millions (USD). Remnant moisture from Nineteen-E led to severe flooding within the U.S. states of Arizona, Texas, Oklahoma, and Arkansas and the death of one person. Damage estimates totaled about $250 million (USD) in the aforementioned states. Minor damage was also reported in New Mexico.Tropical Storm Patricia (2009)
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 (hPa; 29.41 inHg). 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.
Although the center of Patricia did not impact land, the outer bands caused significant rainfall in portions of western Mexico. In Sonora, up to 240 mm (9.4 in) of rain fell, leading to significant flooding that left 600 people homeless. Other Mexican states received similar impact. Overall, the effects of Patricia were minor and resulted in no loss of life.
