Posted: Sun Feb 22, 2004 3:45 pm
The National Weather Service in San Diego, California has issued a flash flood warning, in effect for burned areas of San Diego County until 5 PM PST, and for burned areas of southwestern San Bernardino County in effect until 5 PM PST.
A urban a small stream flood advisory is in effect and has been extended until 5 PM PST for the San Diego County coastal areas, the inland empire, and Orange County, California.
Through 5 PM PST, expect Heavy rain showers with isolated thunderstorms in the burned areas of San Diego and southwestern San Bernardino Counties. Rainfall rates of over 1/2 inch an hour is possible over the burned areas. This type of rain on top of burned areas will likely cause flash flooding as well as deadly mudslides and rockslides.
Residents and persons driving in the burned areas need to be on the alert for heavy mud and debris flows, which may block roads and culverts. Potentially dangerous flooding and property loss could be occurring with this storm.
A flash flood warning is issued when flash flooding is immient or is occurring. Move to higher ground and do not drive or walk through flooded roadways because of unknown depth. Also water weighs 60 pounds a cubic foot. That's alot of water that's overtaking your body when combined with the swift current. Bottom line, don't take any chances. Flash flood watch continues until 3 am for Los Angeles and San Diego areas.
Additional heavy rain is expected this evening as another upper disturbance moves into southern California. Rain could be heavy at times with isolated thunderstorms in LA and San Diego. In addition snow levels are expected to drop between 4500 and 5000 feet later today in southern California.
