Calexico, the town this property stands in, in 11 storm reports between 2011 and 2025: 10 thunderstorm wind, 1 flash flood.
The reports record 1 injury. Each account below is quoted exactly as the forecast office
filed it, from the NOAA Storm Events Database, and each date
opens the federal record of that event.
A tree fell into a home due to strong winds near Encanto Drive and 8th street. The tree caused very minor damage to the eaves of the home and the resident suffered minor injuries that did not need to be treated by authorities. Additional details of the injury were not provided. Winds were estimated around 45-50 mph based on area weather stations and radar. Timing estimated from radar.
A strong thunderstorm with damaging microburst winds moved across the community of Calexico, south of Imperial, during the late afternoon on July 7th. Law enforcement and emergency management personnel reported that a number of trees were downed, and there was transformer damage as well. In addition, winds with gusts estimated to 70 knots damaged 30 homes, and 2 homes were destroyed by falling trees.
Very strong thunderstorms developed across the higher terrain of northern Baja during the early afternoon hours, and then moved north into south-central Imperial County. Some of the storms generated gusty and damaging microburst winds estimated to be as high as 70 mph. According to a local emergency manager, at 1300PST gusty winds blew down 20 to 23 power poles along Carr Road, approximately 4 miles east of the town of Calexico and just north of the Mexican border. This caused the road to become closed from California Highway 7 to Barbara Worth Road.
A thunderstorm with damaging microburst winds moved through the community of Calexico during the late afternoon on July 7th. As reported by law enforcement personnel, wind gusts estimated to be at least 60 knots toppled at least 6 power poles. The winds also knocked over several trees in central Calexico. In addition, heavy rain associated with the thunderstorm caused street flooding in town.
Strong thunderstorms developed over the higher terrain of northwestern Mexico during the afternoon hours on September 7th, and they generated very strong and damaging outflow winds which spread north and into the community of Calexico. According to a trained weather spotter about 1 mile west of Calexico, gusty outflow winds estimated to be at least 75 mph in strength blew down numerous trees and cause some damage to roofs in the area. Street flooding was also reported. No injuries were reported as a result of the strong winds.
Thunderstorms developed south of the Mexican border during the afternoon on August 13th. Due to the excessive heat and dry conditions, the storms were able to generate strong, gusty and damaging outflow winds. The strong winds spread to the north and into the southern portion of Imperial county, including the towns of Calexico and Heber. At 410 pm, a trained weather spotter in Calexico reported a number of trees downed, including some that were blocking a road. Additionally, at 405 pm an emergency manager in Heber reported trees downed by winds estimated to be 50 mph. The strong winds also created dust storm conditions, which lowered visibility to near zero in dense blowing dust. Fortunately, no accidents or injuries were reported due to the strong winds or dense blowing dust.
A tree fell in the area of Sterling Court and Rockwood Avenue due to strong winds. The tree reportedly fell through a fence and took down a power pole. Wind gusts estimated around 45-50 mph based on area weather stations and radar. Timing estimated from radar. No injuries were reported.
Downed powerlines/poles led to the closure of Highway 111 near Cole Blvd. Wind gusts were estimated at 60-65 mph. Timing estimated from radar. No injuries reported.
A line of thunderstorms developed across central Imperial County during the early afternoon hours and some of the stronger storms produced very heavy rainfall which impacted areas from the Imperial Valley south to the Mexican Border. Peak rain rates were in excess of 2 inches per hour and led to episodes of flash flooding. At 1339PST a local emergency manager reported significant flooding on California Highway 98 to the east of Calexico and west of Highway 7. A Flash Flood Warning was in effect at the time of the flooding; it was issued at 1316PST and remained in effect through 1600PST.
Calexico Public Works Department reported a couple street lights/lamps came down in strong winds, with one on the 800 block of Third Street and the other on Emilia Drive. Winds were estimated around 45-50 mph based on area weather stations and radar. Timing estimated from radar. No injuries reported.
