TODAY. AT THIS TIME...THE COMPOSITE RADAR IMAGERY SHOWS WIDESPREAD
LIGHT TO MODERATE RAIN ACROSS THE REGION. HOWEVER...A BAND OF MUCH
STRONGER SHOWERS IS NOW MOVING ONSHORE ACROSS ORANGE COUNTY...WITH

LINE. MEANWHILE...SNOW LEVELS THIS MORNING HAVE INCREASED TO AROUND
9000 FEET...WITH SNOW ONLY POSSIBLE ABOVE THE HIGHEST PEAKS.
HOWEVER...SNOW LEVELS WILL SLOWLY LOWER TODAY BEHIND THE COLD
FRONT...TO AROUND 6500 LATE THIS AFTERNOON AND EVENING.
NEEDLESS TO SAY...IT WILL BE A WET AND SOGGY DAY TODAY...WITH STRONG
AND GUSTY WINDS POSSIBLE. OUR LOCAL WRF SHOWS 850 MB WINDS RANGING
BETWEEN 40 AND 55 KTS THROUGH THIS EVENING...WITH THE HIGHEST GUSTS

THUNDERSTORMS WILL ALSO BE CAPABLE OF PRODUCING DAMAGING STRAIGHT
LINE WINDS AS WELL AS ISOLATED WATER SPOUTS OR TORNADOES.
ANOTHER DISTURBANCE WILL MOVE ACROSS SOUTHERN CALIFORNIA ON

CONTINUE INTO SATURDAY...BUT WILL LIKELY BE MORE SHOWERY IN NATURE.
THESE SHOWERS WILL CONTINUE TO BE MODERATE IN NATURE...WITH PERIODS

POSSIBILITY OF GUSTY AND ERRATIC WINDS...SMALL HAIL...HEAVY RAIN AND
A WATERSPOUT OR TWO THROUGH SATURDAY. SEE LAXMWSSGX FOR ADDITIONAL
DETAILS. A GALE WARNING IN IS EFFECT FOR THE COASTAL WATERS FOR
STRONG S-SW WINDS TO 35 KT AND LARGE SEAS TO 14 FEET. SEE LAXMWWSGX
FOR FURTHER INFORMATION. THE LARGE SWELL WILL CREATE HIGH SURF ALONG
THE BEACHES...WITH SETS TO 12-15 FEET POSSIBLE...ESPECIALLY ON
WESTERLY FACING BEACHES. SURF IS EXPECTED TO FALL BELOW 7 FEET BY
MONDAY...THEN INCREASE AGAIN LATE TUESDAY. STRONG AND DANGEROUS RIP
CURRENTS WILL BE POSSIBLE THROUGH EARLY NEXT WEEK. HIGH
SURF...HIGHER THAN NORMAL HIGH TIDES AND PRECIPITATION RUN-OFF WILL
INCREASE THE CHANCES OF COASTAL FLOODING OF LOW-LYING AREAS ALONG
THE BEACHES...AS WELL. SEE LAXCFWSGX FOR INFORMATION ON HIGH SURF

.HYDROLOGY...
A STRONG PACIFIC STORM SYSTEM OFF THE CALIFORNIA COAST WILL SLOWLY
MOVE INLAND THROUGH SUNDAY...BRINGING LIGHT TO MODERATE SHOWERS TO
THE REGIONS. PERIODS OF HEAVY RAIN WILL BE POSSIBLE...ESPECIALLY AS
THUNDERSTORMS DEVELOP. RAINFALL TOTALS THROUGH SUNDAY WILL RANGE
FROM 2 TO 3 INCHES NEAR THE COAST TO 5 TO 8 INCHES ON THE COASTAL
MOUNTAIN SLOPES...WITH LOCALLY GREATER AMOUNTS ON THE SOUTH SLOPES
OF THE SAN BERNARDINO COUNTY MOUNTAINS. DESERT AREAS COULD SEE UP
TO AN INCH OF PRECIPITATION. SNOW LEVELS DID INCREASE THIS MORNING
TO AROUND 9000 FEET...BUT WILL FALL LATE THIS AFTERNOON AND EVENING
TO BETWEEN 6000 AND 6500 FEET...AS THE COLD FRONT MOVES ACROSS THE
REGION. SNOW LEVELS WILL CONTINUE TO FALL TO BETWEEN 5000 TO 5500
FEET SATURDAY AFTERNOON INTO SUNDAY. SNOWFALL OF 10 TO 20 INCHES IS
POSSIBLE ABOVE 6500 FEET AND COULD LOCALLY EXCEED 4 FEET ABOVE 7500
TO 8000 FEET.
STEADY LIGHT TO MODERATE RAIN CONTINUES ACROSS THE SOUTHLAND THIS
MORNING. HOWEVER...RADAR IMAGERY NOW SHOWS A BAND OF MODERATE TO
HEAVY SHOWERS...EXTENDING FROM DUATE THROUGH AZUSA AND ANAHEIM DOWN
TO COSTA MESA AND HUNTINGTON BEACH. THIS LINE OF MODERATE AND HEAVY
SHOWERS IS JUST THE BEGINNING OF WHAT WE WILL LIKELY SEE TODAY...AS
STRONG SOUTH TO SOUTHWEST INCREASE...BRINGING STRONG OROGRAPHIC LIFT
TO A SUBTROPICAL PLUME OF MOISTURE. RAINFALL RATES OF 1 TO 2 INCHES
PER HOUR ARE POSSIBLE AT TIMES THROUGH THIS AFTERNOON ON SOUTH
FACING SLOPES OF THE SAN BERNARDINO COUNTY MOUNTAINS. SHOWERS WILL
CONTINUE AT TIMES FOR TONIGHT INTO SUNDAY. COLDER MID LEVEL AIR WILL
DESTABILIZE THE ATMOSPHERE AS WELL...WITH SCATTERED THUNDERSTORMS
FOR THIS AFTERNOON INTO SATURDAY.
THE WIDESPREAD AND HEAVY PRECIPITATION AMOUNTS AND RAINFALL RATES
TODAY COULD BE SUFFICIENT TO CAUSE FLASH FLOODING...ESPECIALLY ON
COASTAL MOUNTAIN SLOPES AND NEAR AND DOWNSTREAM OF RECENT BURN
AREAS. HIGH INTENSITY RAINFALL FROM SHOWERS AND ISOLATED
THUNDERSTORMS ON TOP OF NEWLY SATURATED SOIL WILL CONTINUE THE FLASH
FLOODING THREAT FOR TONIGHT THROUGH LATE SATURDAY NIGHT.

FASHION VALLEY...AS IT WILL LIKELY RISE TODAY FROM 1.8 FEET THIS
MORNING TO 7.8 FEET BY 7 PM THIS EVENING. MONITOR STAGE IS AT 7.5
