When was the last time a tropical storm hit Southern California?
The last time a tropical storm made landfall in California was 84 years ago — before there was
The 1939 storm, called El Cordonazo, became the first and only tropical storm to make landfall in the state in the 20th century, according to the National Weather Service. NWS says the storm, which was at one point a hurricane, originated off the southern coast of Central America before moving north and eventually coming ashore at San Pedro, California.
Resulting floods from the storm killed at least 45 people across the Southern California region and caused $2 million in damage to structures and crops, the weather service reports. Another 48 people were also killed at sea. Cities across the Southern California region experienced torrential rains because of the tropical storm — Los Angeles, for example, saw 5.24″ in just 24 hours.
“Californians were generally unprepared and were alerted to their vulnerability to tropical storms,” NWS said of the storm in its report about significant weather events in Southern California. The weather bureau established a forecast office in Southern California in 1940 after the disaster.
Has California ever had a hurricane?
Other powerful storms have hit Southern California, including a hurricane in 1858 that hit San Diego with 75 mph winds — what would now be considered a. The hurricane, which caused extensive wind damage, is considered the only actual hurricane to hit the West Coast, according to National Weather Service.
In 1997, NWS says Hurricane Linda in the Pacific became the strongest storm recorded in the region, with 180 mph winds and 218 mph gusts. However, it didn’t make landfall in California, but as a nearby tropical storm it did cause heavy rain and thunderstorms in the area.
That hurricane occurred during an El Niño, which is a weather pattern that is caused when warmer water in the Pacific Ocean effects the jet stream, making it move south. This phenomenon can bring heavy rainfall and flooding to California and drier and warmer weather to the northern U.S. and Canada. The pattern also affects the U.S. Gulf Coast and Southwest, bringing wetter weather than usual.

Where and when will Hurricane Hilary make landfall?
On Friday morning, Hilary was off the coast of Cabo San Lucas, Mexico, according to the Weather Channel. Hilary grew from a tropical storm to a Category 3 on Wednesday, and then a Category 4 on Thursday. It was expected to continue its path to Southern California and weaken back to a tropical storm — with the remnants still expected to bring flash flooding and gusty winds.
The Los Angeles Basin and the desert Southwest are expected to feel its impact over the weekend, with heavy rainfall in the area starting Friday and “peaking on Sunday and Monday,” according to the National Hurricane Center.. Hilary will continue to drench parts of California early next week while weakening.
How can Californians prepare for Hilary?
According to the National Weather Service, all people living along the coast are at risk of being affected by a hurricane or a tropical storm brewing in their region. The best thing those residents can do is prepare ahead of time.
That preparation includes developing an evacuation and communication plan, stocking up on disaster supplies, preparing your home by cutting down vulnerable trees, and staying up to date on weather forecasts and warnings. Homeowners may want to consider installing a generator and storm shutters, and check your home’s insurance status.
