PRECAUTIONARY/PREPAREDNESS ACTIONS...
People with interests along the river should prepare for flood
conditions and be ready to move to higher ground. Follow emergency
official instructions.
River flooding can cause additional hazards like bank collapse and
shifting channels. Avoid areas adjacent to a flooding river since the
earth underneath may be eroded. Do not let children play near
floodwaters...especially around culverts and storm drains.
Do not drive through flood prone areas...low water crossings...or go
around barricades. The road ahead may be undermined or washed out and
the water depth too great to allow your car to cross safely.
For the latest developments listen to NOAA Weather Radio or tune to
your local tv or radio station. Information can also be obtained from
the NWS website at www.wrh.noaa.gov/mtr
The next statement will be issued by Dec 15, 2016 at 5pm or
sooner as conditions warrant.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN FRANCISCO BAY AREA
346 PM PST THU MAR 10 2016
...HEAVY RAIN LIKELY INTO THE WEEKEND ESPECIALLY FOR THE NORTH
BAY...
.SYNOPSIS...CONTINUED MODERATE TO LOCALLY HEAVY RAINFALL WILL
PERSIST THIS EVENING ACROSS THE NORTH BAY AND GREATER SAN
FRANCISCO BAY AREA. WIDESPREAD RAINFALL WILL THEN SPREAD ACROSS
THE ENTIRE REGION FRIDAY MORNING AS A COLD FRONT PUSHES INLAND.
AFTER A BRIEF BREAK IN RAINFALL FRIDAY NIGHT INTO SATURDAY
MORNING, PERIODS OF MODERATE TO LOCALLY HEAVY RAINFALL AND BREEZY
TO GUSTY WINDS WILL BE POSSIBLE THROUGH THE WEEKEND INTO EARLY
MONDAY AS ADDITIONAL SYSTEMS IMPACT THE REGION.
&&
.DISCUSSION...AS OF 03:45 PM PST THURSDAY...AN ATMOSPHERIC RIVER,
OR DEEP PLUME OF ATMOSPHERIC MOISTURE, REMAINS AIMED AT THE REGION
THIS AFTERNOON, ESPECIALLY OVER THE NORTH BAY. AS THE MAIN
MID/UPPER LEVEL SYSTEM THAT PUSHED THIS PLUME OF MOISTURE DOWN
INTO THE REGION HAS LIFTED INTO BRITISH COLUMBIA AND ALLOWED FOR
THE BOUNDARY TO STALL, GENERALLY NORTH OF THE SAN FRANCISCO BAY
AREA. AFTER A BRIEF LET UP IN PRECIPITATION OVER THE NORTH BAY,
THE LATEST RADAR AND SATELLITE IMAGERY INDICATES AN INCREASE IN
COVERAGE AND INTENSITY OF PRECIPITATION EXTENDING FROM OFF THE
COAST FEEDING UP INTO THE NORTH BAY AND OVER MUCH OF THE SAN
FRANCISCO BAY AREA. WITH RAINFALL AMOUNTS OF AROUND 0.25" PER
HOUR, DO EXPECT CONTINUED FLOODING CONCERNS OVER THE NORTH BAY
THROUGH THE AFTERNOON/EVENING. THE FORECAST MODELS GENERALLY SHOW
A SLIGHT LET UP IN PRECIPITATION OVERNIGHT ACROSS THE SAN
FRANCISCO BAY AREA WITH THE FOCUS FOR CONTINUED RAINFALL SHIFTING
BACK OVER THE NORTH BAY.
AN APPROACHING MID/UPPER LEVEL SYSTEM WILL THEN DRIVE A FRONTAL
BOUNDARY THROUGH THE ENTIRE REGION TOMORROW MORNING THAT WILL BRING
WIDESPREAD RAINFALL TO MUCH OF THE REGION. SOUTHERLY WINDS WILL
BECOME BREEZY TO LOCALLY GUSTY TONIGHT AND INTO FRIDAY MORNING AHEAD
OF THE APPROACHING SYSTEM. WINDS WILL GENERALLY BE IN THE 15 TO 25
MPH RANGE WITH GUSTS OVER 30 MPH. COULD SEE HIGHER WIND GUSTS IN THE
HIGHER ELEVATIONS, ESPECIALLY COASTAL RANGES. IN ADDITION, AS THE
MAIN MID/UPPER LEVEL LOW PUSHES INLAND, THE ATMOSPHERE WILL BECOME
MORE UNSTABLE AND LEAD TO THE POSSIBILITY OF THUNDERSTORMS FROM LATE
FRIDAY MORNING INTO FRIDAY AFTERNOON. IN WAKE OF THE FRONTAL
PASSAGE, LINGERING SHOWERS WILL BE LIKELY THROUGH FRIDAY AFTERNOON
AND EVENING. WIDESPREAD RAINFALL HOWEVER WILL TAPPER OFF FRIDAY
NIGHT WITH A BRIEF BREAK IN PRECIPITATION POSSIBLE, ESPECIALLY INTO
EARLY SATURDAY MORNING.
ADDITIONAL RAINFALL FROM THIS AFTERNOON THROUGH FRIDAY NIGHT WILL
RANGE FROM AROUND 2 INCHES OVER THE NORTH BAY VALLEYS TO 2.50" TO
4.50" IN THE NORTH BAY MOUNTAINS. FURTHER DOWN THE COAST, RAINFALL
AMOUNTS OF 0.50" TO 1.50" WILL BE POSSIBLE IN THE URBAN AREAS AROUND
THE SAN FRANCISCO AND MONTEREY BAY REGIONS (MOSTLY FRIDAY MORNING AS
THE MAIN FRONT PUSHES THROUGH). COASTAL RANGES OUTSIDE OF THE NORTH
BAY COULD SEE RAINFALL AMOUNTS OF 1.50" TO 2.50" TROUGH FRIDAY
NIGHT.
BY SATURDAY AFTERNOON AND EVENING, A WEAK SYSTEM WILL DROP SOUTHWARD
OVER THE REGION BEGINNING OVER THE NORTH BAY AND SPREADING INTO THE
SAN FRANCISCO BAY AREA LATE SATURDAY NIGHT INTO SUNDAY MORNING. THE
AVAILABLE MOISTURE WILL BE LESS THAN WHAT WE HAVE WITH THE CURRENT
ATMOSPHERIC RIVER, GENERALLY WITH PWAT VALUES BETWEEN 0.75" TO
1.00". THIS WILL RESULT IN ADDITIONAL RAINFALL OVER THE REGION WITH
THE HEAVIEST AGAIN OVER THE NORTH BAY AND DOWN THE COASTAL RANGES. A
THIRD SYSTEM IS THEN EXPECTED TO PUSH THROUGH THE REGION SUNDAY
AFTERNOON WITH ADDITIONAL WIDESPREAD RAINFALL EXPECTED. LINGERING
SHOWERS WILL THEN BE POSSIBLE INTO MONDAY MORNING WITH PRECIPITATION
TAPERING OFF REGION-WIDE MONDAY NIGHT INTO TUESDAY MORNING. CAN
ALSO EXPECT BRIEF BREEZY TO LOCALLY GUSTY WINDS AHEAD OF AND BEHIND
EACH OF THESE PASSING SYSTEMS. FROM EARLY SATURDAY MORNING INTO
MONDAY MORNING, ADDITIONAL RAINFALL AMOUNTS WILL RANGE FROM 1" TO 3"
ACROSS THE COASTAL RANGES FROM THE NORTH BAY DOWN THROUGH THE
CENTRAL COAST. NORTH BAY VALLEYS COULD PICK UP AN ADDITIONAL 1" TO
2" WITH MOST URBAN AREAS ACROSS THE SAN FRANCISCO AND MONTEREY BAY
REGIONS PICKING UP 0.50" TO 1.00" (LESSER AMOUNTS POSSIBLE DOWN THE
SOUTHERN SALINAS VALLEY).
DRY WEATHER CONDITIONS THEN RETURN FOR THE REMAINDER OF NEXT WEEK AS
MID/UPPER LEVEL HIGH PRESSURE BUILDS ALONG THE WEST COAST.
&&
.AVIATION...AS OF 9:55 AM PST THURSDAY... WET AND UNSETTLED WEATHER
THROUGH THE NEXT 30 HOURS WILL BRING HEAVY RAINS... GUSTY WINDS...
IFR TO MVFR CIGS AND VISBYS... AND POTENTIALLY SMALL HAIL AND
THUNDERSTORMS. A TROPICAL MOISTURE PLUME WILL TAKE AIM AT THE NORTH
BAY THIS MORNING BEFORE SHIFTING INTO THE GREATER BAY AREA INTO
MIDDAY AND THE EARLY AFTERNOON. THE SURFACE FRONT ASSOCIATED WITH
THIS MOISTURE PLUME IS FORECAST TO STALL INTO THE EARLY AFTERNOON
AND RETREAT NORTHWARD INTO THE EVENING. THIS COULD LEAVE PORTIONS OF
THE SOUTH AND EAST BAY ON THE FRINGE OF THE WET/DRY LINE THROUGH
TODAY. KMRY AND KSNS WILL LIKELY STAY DRY TODAY WITH ONLY A FEW
LINGERING SHOWERS PRECEDING THE FRONT PUSHING THAT FAR SOUTHWARD.
SOUTHERLY WINDS PICK UP OVERNIGHT AS THE UPPER TROUGH
BEGINS TO PUSH INLAND. AS THE UPPER TROUGH PUSHES INLAND... EXPECT
TO SEE A SECOND HEAVY PUSH OF PRECIPITATION ORIGINATING FROM LARGE
SCALE UPPER LEVEL FORCING. THIS WILL LEAD TO WIDESPREAD RAIN BY
15Z FRIDAY... WITH THUNDERSTORMS POSSIBLE FROM THE BAY AREA AND
SOUTHWARD BETWEEN 18FRI TO 00Z SAT. LIGHT TO MODERATE RAIN
SHOWERS WILL THEN PUSH ACROSS THE REGION THROUGH FRIDAY AFTERNOON.
VICINITY OF KSFO...RAINY BY 19Z THU. PREDOMINATELY MVFR CIGS
THROUGH THE FORECAST PERIOD... WITH POSBL IFR VISBYS THIS
AFTERNOON. THERE IS A CHANCE THERE WILL BE A WINDOW OF VFR CIGS
BETWEEN 04Z FRI THROUGH 15Z FRI AFTER THE FRONTAL BOUNDARY WEAKENS
AND BEFORE THE UPPER TROUGH ARRIVES. GUSTY WINDS FRIDAY MORNING.
SLIGHT CHANCE OF TSTORMS AFTER 18Z FRI.
CONFIDENCE IS MODERATE.
KSFO BRIDGE APPROACH...SIMILAR AS KSFO.
MONTEREY BAY AREA TERMINALS...MIXED BAG OF CIGS THIS MORNING...
WITH VFR EXPECTED BY THE AFTERNOON. THIS AREA SHOULD MISS MOST OF
THE HEAVY RAIN EXPECTED IN THE BAY AREA ON THURSDAY. UPPER TROUGH
WILL BRING MVFR TO IFR FLIGHT CONDS AND WIDESPREAD RAIN TO THE
REGION BY FRIDAY MORNING... WITH A SLIGHT CHANCE OF TSTORMS AFTER
15Z FRI.
CONFIDENCE IS MODERATE.
&&
.MARINE...AS OF 03:45 PM PST THURSDAY...SOUTHERLY WINDS ARE
FORECAST TO STRENGTHEN OVERNIGHT AHEAD OF AN APPROACHING UPPER
LEVEL SYSTEM. THE STRONGEST SOUTHERLY WINDS WILL BE SOUTH OF POINT
REYES AROUND SUNRISE FRIDAY. BY FRIDAY AFTERNOON... WINDS VEER
TOWARDS THE WEST AND REMAIN MODERATE TO STRONG. A LARGE LONG
PERIOD SWELL WILL MOVE INTO THE COASTAL WATERS FROM SUNDAY INTO
MONDAY.
