A slow-moving weather system passed through Southern California Sunday, leaving a trail of tiny hailstones, funnel clouds and brief but violent rain squalls that dumped record rainfall in San Diego.
According to the National Weather Service, 1.13 inches of rain fell Sunday at Lindbergh Field, washing out the old April 6 record of .40 of an inch of rain in 1984.
Forecaster Harvey Hastrup said .49 of an inch of Sunday's rain fell in just one hour--between 3 and 4 a.m.
An upper-level, low-pressure area over the ocean just west of Vandenberg Air Force Base in Central California was blamed for the storm. Meteorologists said the disturbance would probably keep pushing cold and unstable air ashore until it moves eastward into the desert sometime tonight.
Meanwhile, it was impressive enough to cause the weather service to issue a severe thunderstorm watch for Los Angeles, Ventura, Orange, San Diego, Riverside, San Bernardino and Kern counties and coastal waters Sunday afternoon.
