...POWERFUL WINTER STORM EXPECTED FOR SOUTHWEST CALIFORNIA
LATE THURSDAY INTO FRIDAY...

A POWERFUL WINTER STORM IS EXPECTED TO BRING PERIODS OF MODERATE
TO HEAVY RAINFALL...STRONG WINDS...MOUNTAIN SNOW...AND HIGH SURF
TO THE REGION LATE THURSDAY INTO FRIDAY. THE INITIAL COLD FRONT
IS EXPECTED TO BRING A 4 TO 6 HOUR PERIOD OF MODERATE TO HEAVY
RAINFALL TO THE CENTRAL COAST THURSDAY EVENING...SPREADING TO THE
LOS ANGELES BASIN LATE THURSDAY NIGHT INTO EARLY FRIDAY MORNING.
BEHIND THE MAIN FRONT...A COLD AND UNSTABLE AIR MASS WILL CONTINUE
TO BRING THE THREAT OF SHOWERS INTO FRIDAY EVENING...CAPABLE OF
PRODUCING BRIEF HEAVY DOWNPOURS. RAINFALL TOTALS WITH THIS SYSTEM
FROM THURSDAY AFTERNOON THROUGH FRIDAY NIGHT ARE EXPECTED TO RANGE
FROM 1 TO 2 INCHES FOR COASTAL AND VALLEY LOCATIONS AND 2 TO 4
INCHES ACROSS THE FOOTHILLS AND MOUNTAINS. THE HIGHEST RAINFALL
TOTALS ARE EXPECTED ACROSS SAN LUIS OBISPO AND SANTA BARBARA
COUNTIES...ESPECIALLY SOUTH AND SOUTHWEST FACING SLOPES.

THIS WEATHER SYSTEM WILL ALSO BRING A SLIGHT CHANCE OF THUNDERSTORMS
TO THE REGION...WHERE THERE WILL BE THE POTENTIAL FOR BRIEF HIGH
INTENSITY RAINFALL...SMALL HAIL...AND GUSTY WINDS. RAINFALL RATES
BETWEEN ONE HALF AND THREE QUARTERS OF AN INCH PER HOUR WILL BE
POSSIBLE WITH THE COLD FRONT AND THUNDERSTORM DEVELOPMENT. THESE
PROJECTED RAINFALL RATES ARE HIGHER THAN LAST WEEK`S STORM...BRINGING
A GREATER THREAT OF FLASH FLOODING WITH MUD AND DEBRIS FLOWS IN
AND NEAR RECENT BURN AREAS. AS WE DRAW CLOSER TO THE EVENT...A FLASH
FLOOD WATCH WILL LIKELY BE REQUIRED FOR THE RECENT BURN AREAS.
DUE TO THE INSTABILITY AND WIND SHEAR ASSOCIATED WITH THIS SYSTEM...
CONDITIONS WILL ALSO BE FAVORABLE FOR ISOLATED WATERSPOUTS ACROSS
THE COASTAL WATERS.

THIS PACIFIC STORM IS ALSO EXPECTED TO PACK POWERFUL WINDS. HIGH
WIND WATCHES HAVE ALREADY BEEN POSTED FOR THE MOUNTAINS...WHERE
THERE WILL BE THE POTENTIAL FOR STRONG SOUTHERLY WINDS WITH DAMAGING
WIND GUSTS OVER 70 MPH POSSIBLE. ELSEWHERE...WINDY CONDITIONS WILL
LIKELY DEVELOP AHEAD OF THE FRONT WITH WIND GUSTS BETWEEN 35 AND 50
MPH ACROSS MANY COASTAL AND VALLEY LOCATIONS...AND ISOLATED GUSTS
TO 60 MPH ACROSS FOOTHILL LOCATIONS. WINDS THIS STRONG MAY DOWN
TREES AND POWER LINES...AND CAUSE PROPERTY DAMAGE. DANGEROUS DRIVING
CONDITIONS ARE ALSO EXPECTED.

THE SNOW LEVEL WILL INITIALLY BE ABOVE RESORT LEVEL DUE TO THE STRONG
SOUTHERLY WINDS AHEAD OF THE FRONT. HOWEVER...SNOW LEVELS ARE EXPECTED
TO FALL RAPIDLY ON FRIDAY...LOWERING TO BETWEEN 4000 AND 5000 FEET
ON FRIDAY AFTERNOON AND EVENING. MOST OF THE SNOW ACCUMULATION IS
EXPECTED ABOVE 5000 FEET BUT COULD SEE SOME IMPACT ALONG INTERSTATE
5 NEAR THE GRAPEVINE ON FRIDAY NIGHT AS THE COLDER AIR MOVES INTO
THE REGION.

RESIDENTS OF SOUTHWEST CALIFORNIA...ESPECIALLY THOSE WHO LIVE NEAR
THE RECENT BURN AREAS...SUCH AS THE COLBY AND SPRINGS BURN
AREAS...SHOULD MONITOR THE LATEST NATIONAL WEATHER SERVICE FORECASTS
AND STATEMENTS ABOUT THIS POTENTIALLY SIGNIFICANT STORM SYSTEM.

LISTEN TO NOAA WEATHER RADIO OR YOUR FAVORITE LOCAL MEDIA OUTLET
FOR THE LATEST UPDATES ON THIS STORM SYSTEM.
