...A STRONG PACIFIC STORM WILL AFFECT SOUTHWEST CALIFORNIA MONDAY
AND TUESDAY...

A MOISTURE LADEN...LOW PRESSURE SYSTEM OVER THE EASTERN PACIFIC WILL
BRING POTENTIALLY HEAVY RAINS AS IT TAPS INTO A DEEP LAYER OF
SUBTROPICAL MOISTURE.

LIGHT RAIN COULD BEGIN AS EARLY AS SUNDAY NIGHT...THEN INTENSIFY
LATER MONDAY AS SOUTHERLY WINDS DRAW MORE MOISTURE INTO SOUTHERN
CALIFORNIA. THE BEST CHANCES FOR HEAVY RAIN WILL BE MONDAY NIGHT
WHEN THE COLD FRONT SWEEPS ACROSS THE REGION.

RAINFALL AMOUNTS WILL RANGE FROM 1 TO 3 INCHES IN THE COASTAL AND
VALLEY AREAS...AND FROM 3 TO 6 INCHES IN THE MOUNTAINS AND ALONG THE
COASTAL SLOPES. THE SOUTH AND SOUTHWEST FACING SLOPES WILL LIKELY
RECEIVE THE MOST RAIN.

RAINFALL INTENSITIES MONDAY NIGHT COULD EXCEED ONE HALF INCH PER
HOUR AT TIMES ACROSS LOWER ELEVATIONS...WITH RATES IN EXCESS OF ONE
INCH PER HOUR POSSIBLE ACROSS FOOTHILL AND MOUNTAIN LOCATIONS. WITH
SUCH HIGH RAINFALL RATES...FLASH FLOODING...MUD SLIDES AND DEBRIS
FLOWS WILL BE LIKELY...ESPECIALLY IN AND BELOW RECENTLY BURNED AREAS
AND ON STEEP TERRAIN. URBAN AND SMALL STREAM FLOODING WILL ALSO BE
POSSIBLE AT THE LOWER ELEVATIONS.

THE WARM TROPICAL AIR ASSOCIATED WITH THIS SYSTEM WILL KEEP SNOW
LEVELS ABOVE RESORT LOCATIONS UNTIL MONDAY NIGHT SO THAT ANY SNOW
ACCUMULATIONS WILL BE RESTRICTED TO THE HIGHEST PEAKS OF THE SAN
BERNARDINO AND RIVERSIDE MOUNTAINS. AFTER THE PASSAGE OF THE COLD
FRONT...THE SNOW LEVELS WILL DROP TO ABOUT 6000 FEET ON TUESDAY
MORNING BUT SNOW ACCUMULATIONS WILL BE MINOR.

ON MONDAY...STRONG SOUTH TO SOUTHWEST WINDS GUSTING TO 45 MPH WILL
BE POSSIBLE ACROSS THE MOUNTAINS...AND WIND ADVISORIES WILL LIKELY
BE NEEDED FOR SOME AREAS OF THE SAN BERNARDINO...RIVERSIDE AND SAN
DIEGO COUNTY MOUNTAINS.

ALL INTERESTS SHOULD KEEP INFORMED ON THE LATEST DEVELOPMENT OF THIS
STORM BY MONITORING THE LATEST WEATHER STATEMENTS. A FLOOD WATCH
WILL LIKELY BE ISSUED LATER THIS WEEKEND FOR THE HEAVY RAIN EXPECTED
TO FALL MONDAY NIGHT.
