Los Angeles CA Weather Forecast Los Angeles Current Weather

...TWO STORMS TO AFFECT CENTRAL AND SOUTHERN CALIFORNIA THROUGH
SUNDAY...

A PERIOD OF WET WEATHER IS EXPECTED ACROSS CENTRAL AND SOUTHERN
CALIFORNIA AS TWO DIFFERENT STORMS MOVE ACROSS THE AREA.

THE FIRST STORM IS CURRENTLY MOVING INTO SAN LUIS OBISPO AND
SANTA BARBARA COUNTIES THIS AFTERNOON AND WILL AFFECT VENTURA AND
LOS ANGELES COUNTIES TONIGHT AND FRIDAY MORNING. WITH THIS STORM
SYSTEM...MODERATE RAINFALL AMOUNTS ARE EXPECTED AT TIMES THROUGH
FRIDAY MORNING...BUT THERE IS THE POTENTIAL FOR BRIEF HEAVY SHOWERS
AND EVEN A THUNDERSTORM OR TWO CANNOT BE RULED OUT. AT THIS TIME...
THE BEST THUNDERSTORM POTENTIAL WILL BE ACROSS THE CENTRAL COAST
THIS AFTERNOON AND EVENING...THEN THE ENTIRE COASTAL WATERS TONIGHT.
RAINFALL AMOUNTS ARE EXPECTED TO RANGE BETWEEN ONE QUARTER AND THREE
QUARTERS OF AN INCH OF RAINFALL...WITH LOCAL AMOUNTS AROUND ONE
INCH POSSIBLE IN FAVORED UPSLOPE AREAS AND NEAR HEAVIER SHOWERS OR
THUNDERSTORMS. SNOW LEVELS WITH THIS STORM ARE ANTICIPATED TO REMAIN
ABOVE 6000 FEET...SO THE RESORT AREAS WILL LIKELY RECEIVE SEVERAL
INCHES OF SNOWFALL. AT THIS TIME SNOWFALL ACCUMULATIONS OF 3 TO 6
INCHES ARE EXPECTED ABOVE 6000 FEET ACROSS THE MOUNTAINS OF
VENTURA AND LOS ANGELES COUNTIES...WHERE A WINTER WEATHER ADVISORY
HAS BEEN POSTED (PLEASE REFER TO LAXWSWLOX FOR THE LATEST ON THE
SNOWFALL POTENTIAL).

ANY THUNDERSTORMS THAT DEVELOP OVER THE COASTAL WATERS WILL BE
CAPABLE OF PRODUCING WATERSPOUTS (PLEASE REFER TO LAXMWSLOX FOR
THE LATEST MARINE INFORMATION).

DURING THE DAY ON FRIDAY...THERE WILL BE A RELATIVE PRECIPITATION
LULL AS THE AREA WILL BE BETWEEN STORM SYSTEMS. HOWEVER...A MOIST
AND UNSTABLE WESTERLY FLOW WILL PRODUCE SCATTERED SHOWERS THROUGH
FRIDAY EVENING.

LATE FRIDAY NIGHT INTO SATURDAY NIGHT...THE SECOND...AND MORE
POTENT...STORM SYSTEM WILL MOVE THROUGH CENTRAL AND SOUTHERN
CALIFORNIA. THIS SECOND STORM SYSTEM IS ANTICIPATED TO PRODUCE
MORE RAINFALL DUE TO A SUBTROPICAL MOISTURE SOURCE AND STRONG
SOUTH TO SOUTHWEST FLOW AHEAD OF THE STORM. AT THIS TIME... THE
PERIOD OF HEAVIEST RAINFALL IS ANTICIPATED TO BE LATE SATURDAY
AFTERNOON AND EVENING...WITH THE PRECIPITATION TAPERING OFF
THROUGH THE DAY ON SUNDAY. PRELIMINARY RAINFALL ESTIMATES WITH
THIS SECOND SYSTEM ARE EXPECTED TO RANGE FROM 0.50 TO 1.50 INCHES
ACROSS COASTAL AND VALLEY AREAS TO 1.50 TO 2.50 INCHES IN THE
FOOTHILLS AND MOUNTAINS. SNOW LEVELS WITH THIS STORM ARE EXPECTED
TO REMAIN RELATIVELY HIGH THROUGH SATURDAY NIGHT...GENERALLY ABOVE
6000 FEET...DUE TO THE SOUTHERLY WINDS. HOWEVER ON SUNDAY...THE
SNOW LEVELS SHOULD DROP TO AROUND 5500 FEET AS SOME COLDER AIR
FILTERS INTO THE AREA. SIGNIFICANT SNOWFALL ACCUMULATIONS WILL BE
POSSIBLE ABOVE 6000 FEET. SOUTHERLY WINDS BETWEEN 25 AND 35 MPH
WITH GUSTS TO 50 MPH CAN BE EXPECTED ON SATURDAY AND SATURDAY
NIGHT...WITH POSSIBLE DANGEROUS WINTER STORM CONDITIONS IN THE
MOUNTAINS. A WINTER STORM WATCH MAY BE REQUIRED FOR THIS SECOND
SYSTEM.

WITH RAIN CURRENTLY IN THE FORECAST...THERE IS CONCERN ABOUT THE
RECENT BURN AREAS DUE TO POSSIBLE MUD AND DEBRIS FLOWS. AT THIS
TIME...THE FIRST SYSTEM TODAY AND TONIGHT IS NOT ANTICIPATED TO
CAUSE ANY SIGNIFICANT PROBLEMS AS HOURLY RAINFALL RATES ARE NOT
EXPECTED TO EXCEED CRITICAL USGS THRESHOLDS. WITH THE SECOND STORM
ON SATURDAY AND SATURDAY NIGHT...THERE IS MORE CONCERN ABOUT
POTENTIAL MUD AND DEBRIS FLOWS. THE FORECAST PRECIPITATION
TOTALS...AS WELL AS THE POTENTIAL FOR HIGHER HOURLY RAINFALL
RATES...MAY REQUIRE THE ISSUANCE OF FLASH FLOOD WATCHES FOR THE
BURN AREAS.

THIS WILL BE A RAPIDLY DEVELOPING WEATHER SITUATION THE NEXT FEW
DAYS ACROSS CENTRAL AND SOUTHERN CALIFORNIA. STAY TUNED TO NOAA
WEATHER RADIO OR YOUR FAVORITE LOCAL NEWS SOURCE FOR THE LATEST
STATEMENTS CONCERNING THIS WEATHER SYSTEM.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR SOUTHWESTERN CALIFORNIA.

.DAY ONE... TODAY

A STORM SYSTEM WILL MOVE ACROSS THE AREA THIS AFTERNOON AND
TONIGHT...BRINGING RAIN AND SNOW TO CENTRAL AND SOUTHERN CALIFORNIA.
ACROSS SAN LUIS OBISPO AND SANTA BARBARA COUNTIES...THE BEST CHANCE
FOR RAINFALL WILL BE THIS AFTERNOON AND EVENING. ACROSS VENTURA
AND LOS ANGELES COUNTIES...THE BEST CHANCE OF RAIN WILL BE THIS
EVENING AND OVERNIGHT. AT THIS TIME...RAINFALL AMOUNTS ARE EXPECTED
TO RANGE BETWEEN 0.25 AND 0.75 INCHES WITH LOCALLY HIGHER AMOUNTS
POSSIBLE IN THE FOOTHILLS AND MOUNTAINS THROUGH FRIDAY MORNING.
SNOW LEVELS WILL REMAIN AROUND 6000 FEET OR HIGHER WITH 3 TO
6 INCHES OF SNOWFALL EXPECTED ABOVE 6000 FEET. AS THIS STORM
MOVES THROUGH...IT MAY PRODUCE AN ISOLATED THUNDERSTORM TONIGHT
OVER THE CENTRAL COAST.

ACROSS THE COASTAL WATERS...THERE WILL ALSO BE A THUNDERSTORM
THREAT. ANY THUNDERSTORMS THAT DEVELOP TONIGHT WILL BE CAPABLE
OF PRODUCING A WATERSPOUT. IN ADDITION...A LARGE WESTERLY SWELL
WILL CONTINUE THROUGH TONIGHT...PRODUCING HIGH SURF CONDITIONS
ALONG THE BEACHES AND DANGEROUS RIP CURRENTS.
