THIS HAZARDOUS WEATHER OUTLOOK IS FOR SOUTHWESTERN CALIFORNIA.

.DAY ONE... TODAY THROUGH 6 AM SUNDAY

THE COMBINATION OF LONG PERIOD SWELL AND HIGH WIND WAVES WILL
CONTINUE TO GENERATE DANGEROUS AND CHOPPY SEA CONDITIONS
TODAY. HIGH SURF CONDITIONS WILL PREVAIL NORTH OF POINT
CONCEPTION...WITH ABOVE NORMAL SURF CONDITIONS ACROSS WEST FACING
BEACHES SOUTH OF POINT CONCEPTION. THERE WILL CONTINUE TO BE A HIGH
RISK FOR RIP CURRENTS AS WELL AS LOCAL BEACH EROSION TODAY.

ANOTHER UPPER LEVEL IMPULSE WILL INCREASE THE THREAT OF SHOWERS
THIS AFTERNOON...WITH A GOOD CHANCE OF SHOWERS AND EVEN A FEW
THUNDERSTORMS TONIGHT. AT THIS TIME...IT APPEARS THE BEST THREAT
OF SHOWERS WILL BE ACROSS LOS ANGELES COUNTY AND IN THE MOUNTAINS.
DUE TO THE SCATTERED NATURE OF THE SHOWER ACTIVITY...RAINFALL
AMOUNTS WILL REMAIN QUITE VARIABLE. HOWEVER...SINCE THIS
PRECIPITATION WILL BE ASSOCIATED WITH A COLD AND UNSTABLE AIR
MASS...THERE WILL BE THE POSSIBILITY OF BRIEF HEAVY SHOWERS AND
THUNDERSTORMS WHICH COULD CONTAIN SMALL HAIL. IF HEAVY SHOWERS
DO DEVELOP...THEY COULD BE CAPABLE OF PRODUCING MUD AND DEBRIS
FLOWS.

MODERATE SNOWFALL ACCUMULATIONS ARE POSSIBLE IN THE
MOUNTAINS...ESPECIALLY ON NORTHERN SLOPES...AND IN THE EASTERN SAN
GABRIEL MOUNTAINS. SNOW LEVELS ARE EXPECTED TO LOWER TO 3000 FEET
TONIGHT. SNOWFALL COULD LOCALLY FALL TO 2000 FEET IF HEAVIER SHOWERS
OR THUNDERSTORMS DEVELOP...WHICH COULD BRING SNOW AT TIMES TO THE
VALLEY FLOOR IN THE ANTELOPE VALLEY...AS WELL AS PORTIONS OF THE
CUYAMA VALLEY AND INTERIOR VALLEYS OF SAN LUIS OBISPO COUNTY.

DUE TO THE COLD AND UNSTABLE NATURE OF THIS SYSTEM...THERE WILL
ALSO BE THE THREAT OF WATERSPOUTS ACROSS THE COASTAL WATERS...MAINLY
SOUTH OF POINT CONCEPTION...FROM SATURDAY AFTERNOON THROUGH SATURDAY
NIGHT.
