Waterspouts & Weak Tornadoes In Southern CA
Areas of Southern California were placed under tornado warnings on Tuesday January 19th, 2010, including Long Beach, Seal Beach, Huntington Beach, Costa Mesa, Anaheim, Santa Ana, Laguna Beach and San Diego.
Shortly before noon on Tuesday, rotation was indicated on radar near Catalina Island. This developed into a large mesocyclone in 15 min. to a half hour. 4 waterspouts were spotted and as the thunderstorm cell moved onshore near Long Beach there were reports of a tornado touchdown causing damage, one was in Costa Mesa and another in Sunset Beach. One very excited guy caught the roof being peeled off of a building. The video is below and pardon his french.

January 19th, 2010. I used to do the weather on KCBS in Los Angeles 2001-2002 before getting an bigger offer in New York City. By the way this severe weather outbreak is rare for Southern CA. Blame it on the storm track and El Nino. More severe weather is likely Wednesday and Thursday.
Below is one of the tornadoes captured on video as it weakens, even a woman in the video is questioning where it is a tornado, it was a tornado in Orange County and it was in it’s weakening phase January 19th, 2010.
