NATIONAL WEATHER SERVICE LOS ANGELES/OXNARD CA
845 PM PST FRI FEB 11 2000

LATEST RADAR/ALERT GAUGES INDICATE MAIN RAIN MOVING ACROSS SLO AND
WESTERN SBA COUNTIES AT THIS TIME. LATEST WATER VAPOR IMAGERY SHOWS
MAIN UPPER LOW HEADING EAST TOWARDS THE SFO BAY AREA...ALTHOUGH
ACTUAL TRACK IS BIT FURTHER SOUTH THAN THE 00Z ETA/NGM INDICATE.
AT ANY RATE...ETA/NGM CROSS SECTIONS STILL INDICATE STRONG DYNAMICS
AND DEEP MOISTURE MOVING THROUGH THE FORECAST AREA TONIGHT. CURRENT
TIMING OF RAIN STILL ON TRACK...WITH MAIN RAIN BAND ENTERING VTU
COUNTY AFTER 10 PM...AND INTO LAX AFTER MIDNIGHT.

OVERALL...CURRENT FLASH FLOOD WATCH FOR BURN AREAS STILL LOOKS GREAT
AS RAIN SHOULD BE MODERATE TO HEAVY OVERNIGHT. VAD WIND PROFILE FROM
RADARS INDICATE STRONG SOUTHERLY FLOW 25-40 KT WHICH SHOULD HELP
ENHANCE OROGRAPHIC RAINFALL...ESPECIALLY ACROSS SOUTHERN SBA COUNTY.

AS FOR WINTER STORM WARNING...SNOW LEVELS DROPPING TO AROUND 5000
FEET STILL OK...WITH SIGNIFICANT SNOW EXPECTED FOR RESORTS. ALSO...
HAVE STARTED TO GET SOME REPORTS OF SOUTHERLY WINDS GUSTING AROUND
35-40 MPH...WHICH MATCHES PRETTY WELL WITH VAD WIND PROFILE ON RADAR.

WILL ISSUE MINOR ZONE UPDATE AROUND 9 PM TO BUMP UP WINDS IN THE
MOUNTAIN ZONES. OTHERWISE...CURRENT FORECAST/WARNINGS/WATCHES ARE
ON TRACK.

LAX ++35.  THOMPSON.
