Tropical Storm Georgette was a short-lived tropical storm that struck

Pacific ocean 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

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.[1] The area of disturbed weather was first mentioned on the National Hurricane Center (NHC) around that time, but signification development was initially not anticipated.[2] 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.[3]

Gradual development took place as convection consolidated around the

subtropical ridge, the system was steered towards the north-northwest throughout its existence.[1]

Within hours of becoming a depression on September 20, strong wind shear caused convection to diminish. However, data from an

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.[1]

Preparations and impact

Rainfall from Georgette in western Mexico

Prior to the arrival of Georgette, the Mexican government issued a

Los Cabos.[7]

In

Guaymas, 300 people from the city and surrounding areas were placed in shelters; 250 more people sought shelter from Georgette in Empalme.[11] Schools in Bahía Kino and coastal areas of the Hermosillo Municipality suspended classes as a precaution.[12] Classes resumed statewide on September 23.[13]

Georgette caused the heaviest rains on Baja California Sur in the last 15 years, leaving many people homeless.

Los Mochis), causing 500,000 people to be evacuated.[1] 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.[18]

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.[19] The rains caused flooding that killed a person along the Rio Grande near Carnuel.[20]
