Yes. Although Los Angeles County has never experienced the monsters that terrorize the midwest, tornadoes, albeit smaller ones, are not unknown here. Since 1950, at least 42 tornadoes were reported to have occurred in Los Angeles County. Most were quite small, covering short distances and doing little or no damage. Two, however (in 1966 and 1983), swept accross several miles, causing double-digit injuries and significant damage. On March 1, 1983, a twister tore its way from Mid-Wilshire through Ladera Heights, causing 30 injuries and at least $5 million in damage. It holds the record for the most destructive tornado to have occured in Los Angeles County. Tornadoes in Los Angeles County are more likely to appear from November through January. Long Beach, South Los Angeles and South Whittier lead in having seen the most twisters.

Tornado Events in Los Angeles County, 1950 Through 2018

NOTE: Although National Weather Service (NWS) data list 43 tornado events for Los Angeles County since 1950, we list only 42 below. Not shown is a February 19, 1966 tornado event recorded for Los Angeles County (SPC#22). Geographic coordinates provided by NWS, however, placed the event in Tulare County, California, and we could not otherwise confirm a tornado for that date in Los Angeles County. These data are used by the NWS for verification purposes and may not accurately reflect all storm events. Monetary loss information is also highly suspect and should be used with caution, if at all.
