...THE FIRST RAINS OF 2009 ARE EXPECTED ACROSS SOUTHWESTERN
CALIFORNIA TODAY AND TONIGHT...

AN UPPER LEVEL TROUGH OF LOW PRESSURE SEVERAL HUNDRED MILES OFF
THE SOUTHWESTERN CALIFORNIA COAST IS FORECAST TO MOVE SLOWLY EAST
THROUGH TODAY...TRACKING OVER EXTREME SOUTHERN CALIFORNIA TONIGHT.
THIS SYSTEM IS EXPECTED TO BRING SHOWERS WITH SIGNIFICANT RAINFALL
TO THE REGION THROUGH THURSDAY NIGHT.

THERE WILL BE AN INCREASING CHANCE OF SHOWERS OVER MUCH OF
SOUTHWESTERN CALIFORNIA EARLY THIS MORNING. WIDESPREAD SHOWERS WILL
PERSIST ACROSS THE REGION THROUGH THE DAY TODAY THEN GRADUALLY TAPER
TO SCATTERED SHOWERS TONIGHT. SOME SHOWERS MAY LINGER INTO FRIDAY
MORNING...ESPECIALLY ACROSS VENTURA AND LOS ANGELES COUNTIES.

ESTIMATES OF RAINFALL TOTALS FOR THE STORM ARE FOR ONE HALF TO
ONE AND A HALF INCHES IN COASTAL AND VALLEY AREAS...WITH THE HIGHEST
AMOUNTS EXPECTED SOUTH OF POINT CONCEPTION. FOOTHILL AND MOUNTAIN
AREAS ARE GENERALLY EXPECTED TO RECEIVE BETWEEN ONE AND TWO INCHES
OF RAIN. IT LOOKS AS THOUGH SOUTHERLY FLOW WILL PROVIDE SOME
OROGRAPHIC ENHANCEMENT OF THE RAINFALL...SO THE HIGHEST TOTALS ARE
EXPECTED ON SOUTH FACING SLOPES OF SANTA BARBARA...VENTURA AND LOS
ANGELES COUNTIES WHERE LOCAL AMOUNTS OVER THREE INCHES ARE POSSIBLE.

THERE IS A CHANCE THAT RAINFALL RATES WILL BE HIGH ENOUGH TO BRING A
THREAT OF LOCAL FLASH FLOODING AND DEBRIS FLOWS IN AND AROUND THE
RECENTLY BURNED AREAS.

DUE TO THE SUBTROPICAL NATURE OF THE SYSTEM...SNOW LEVELS ARE
EXPECTED TO BE RATHER HIGH...MAINLY ABOVE RESORT LEVELS FOR MUCH OF
THE STORM.

STAY TUNED TO NOAA WEATHER RADIO OR YOUR FAVORITE MEDIA OUTLET FOR
THE LATEST UPDATES ON THE STORMY WEATHER EXPECTED TO AFFECT
SOUTHWESTERN CALIFORNIA.
