Rainclouds hover over the San Gabriel Valley this morning. Isolated showers are expected to continue through the morning over Los Angeles County. Local dense fog will reduce visibility to one quarter mile or less in coastal areas through midmorning.
Scattered storms that formed overnight in Orange County were shifting north, bringing lightning, thunder and showers to Los Angeles and surrounding areas throughout the day, weather forecasters said this morning. Pasadena residents reported a short burst of rain this morning. Shortly before 8 a.m., storm clouds hung over Mt. Wilson in Pasadena, areas north of Santa Clarita and as far east as Pomona, said Stuart Seto, a meteorologist with the National Weather Service in Oxnard. The storms are expected to bring a quarter inch of rainfall or less to some areas into the evening and early nighttime, but will clear up tonight as the likelihood of rain drops to 20%, Seto said. Parts of northern San Diego County were clearing up this morning after thunder and lightning over Mt. Palomar, and a large rainbow stretched all the way to Mission Beach.
Isolated and scattered showers brought less than one tenth of an inch in rain in the San Diego area, and lightning strikes were starting minor fires, said National Weather Service forecaster Robert Balfour. Balfour said storms there were also slowly headed toward Los Angeles at just over 10 mph.
Seto said the storms were caused by southern winds pushing in moisture, adding to unstable atmosphere over Los Angeles and Ventura counties. Temperatures were expected to be warmer than Sunday, with highs in the 80s and 90s. The rest of the week will be mostly sunny with some foggy skies, Seto said.
