How rare are hurricanes and tropical storms in California?
Hurricanes and tropical storms are rare in the Golden State due to the cold water temperatures in the Pacific, according to the NWS.
For hurricanes to happen, water temperatures need to be around at least 80 degrees and California’s coast doesn’t get that warm because of the current that comes from the Gulf of Alaska, FOX40 Chief Meteorologist Adam Epstein said.
Although these storms are rare occurrences, tropical storms and hurricanes have happened before.
The last time a tropical storm made landfall in the state was in the Long Beach area on Sept. 25, 1939.
According to the NWS, the Long Beach tropical storm resulted in 45 deaths due to flooding and 48 deaths at sea. The storm also resulted in $2 million in damage, which equals to $43 million today.
The last hurricane to reach landfall in California occurred in San Diego on Oct. 2, 1858, which had winds estimated at 75 mph, the NWS said.
The hurricane resulted in houses unroofed or blown down, trees uprooted, and ships grounded ashore.
