Flash Flood Warning 3, NWS Los Angeles, CA

SOUTHWEST CALIFORNIA AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
150 PM PST SUN FEB 20 2000

STILL GETTING SOME VERY GOOD SHOWERS OVER VENTURA COUNTY THIS
AFTERNOON ASSOCIATED WITH THE FIRST UPPER LOW THAT MOVED THROUGH OUR
AREA THIS MORNING. SECOND FRONTAL BAND IS STILL WEST OF THE AREA AND IS
POISED TO MOVE ONSHORE VERY SOON ALONG THE CENTRAL COAST AND BY AROUND
6 PM IN THE LA BASIN. VISIBILE IMAGERY SHOWS SOME VERY GOOD VERTICAL
DEVELOPMENT ALONG THE FRONT WHICH WILL RESULT IN ABOUT A 6 HOUR PERIOD
OF PERSISTENT MODERATE TO HEAVY RAIN THROUGHOUT OUR CWA. THIS INITIAL
FRONTAL BAND COULD PRODUCE VERY HEAVY RAINFALL AMOUNTS AND AM CERTAINLY
CONCERNED ABOUT THE BURN AREAS IN LA AND VENTURA COUNTIES TONIGHT AND
MONDAY. A FLASH FLOOD WATCH HAS BEEN POSTED FOR THESE AREAS.

ALTHOUGH THE STEADY RAIN WILL BECOME MORE SHOWERY OVERNIGHT...RAINFALL
WILL STILL BE POTENTIALLY VERY HEAVY AS THE AIRMASS BEHIND THE FRONT IS
VERY UNSTABLE. IN FACT...WE WILL HAVE TO WATCH FOR THE POSSIBILITY OF
STRONG OR SEVERE THUNDERSTORMS DEVELOPING LATER TONIGHT AND MONDAY. AT
THIS POINT SAT IMAGERY SEEMS TO INDICATE THAT THE BEST CHANCE FOR
THUNDERSTORM ACTIVITY BEHIND THE FRONT WILL BE IN THE SOUTHERN PORTION
OF OUR CWA. THE TRACK OF THE LOW IS DEFINITELY HEADED MORE TOWARDS
ORANGE AND SAN DIEGO COUNTIES...HOWEVER THAT CERTAINLY DOESN'T LEAVE
OUR AREA OUT OF THE WOODS.

SNOWFALL WILL ALSO BE SIGNIFICANT...ESPECIALLY AT THE HIGHER
ELEVATIONS. INITIALLY THE SNOW LEVELS WILL BE AROUND 6000 FEET...BUT
SHOULD LOWER QUITE RAPIDLY AS THE FRONT APPROACHES...REACHING ABOUT
4000 FEET BY MONDAY MORNING...AND POSSIBLY A LITTLE LOWER...ESPECIALLY
IN AND NEAR CONVECTION. THE WINTER STORM WATCH HAS BEEN UPGRADED TO A
WARNING SINCE THE SNOW IS EXPECTED TO BEGIN IN EARNEST VERY SHORTLY.
THIS WILL ADD TO THE FEW INCHES OF SNOW THAT HAS ALREADY FALLEN AT
HIGHER ELEVATIONS TODAY.

WE SHOULD BE DRYING OUT TEMPORARILY LATE MONDAY AND TUESDAY.
HOWEVER...MODELS ARE BRINGING ANOTHER GOOD CHANCE OF RAIN TO MOST OF
THE AREA BY WEDNESDAY AND POSSIBLY FRIDAY AS WELL. SINCE TIMING IS
STILL A LITTLE UNCERTAIN...WILL LIKELY BROAD BRUSH THE EXTENDED WITH
PERIODS OF RAIN EVEN THOUGH THE WHOLE EXTENDED PERIOD WILL NOT BE WET.
