A very strong cyclone slammed into the San Francisco and Monterey Bay Areas bringing flooding rains, high winds, record high surf and coastal flooding. Hundreds of thousands of residences and businesses were without power, some for several days due to high winds toppling power lines.

NATIONAL WEATHER SERVICE SAN FRANCISCO CA
1000 PM PST THU JAN 3 2008
UPDATED AVIATION
.DISCUSSION...FORECAST REMAINS ON TRACK THIS EVENING. A FEW NEW
ADVISORIES/WATCHES TO HIGHLIGHT FOR FRIDAY. AN URBAN AND SMALL STREAM
FLOOD ADVISORY HAS BEEN ISSUED FOR SONOMA...MARIN...AND NAPA
COUNTIES BEGINNING AT 4 AM PST FRIDAY MORNING UNTIL 4 PM PST FRIDAY
AFTERNOON. A SECOND URBAN AND SMALL STREAM FLOOD ADVISORY WAS
ISSUED FOR THE REMAINING COUNTIES IN OUR CWA FROM SAN FRANCISCO SOUTH
BEGINNING AT 4 AM PST FRIDAY MORNING UNTIL 10 PM FRIDAY EVENING.
RAINFALL TOTALS WILL EASILY REACH 2 TO 6 INCHES BY FRIDAY AFTERNOON
AS THE FRONT MOVES ACROSS THE REGION. HIGHER ELEVATIONS HAVE THE
POTENTIAL FOR HIGHER RAINFALL TOTALS. BECAUSE OF THE POTENTIAL FOR
HEAVY RAINFALL WITH THIS SYSTEM WE HAVE ALSO ISSUED A FLASH FLOOD
WATCH FOR THE NORTH BAY COUNTIES OF SONOMA...MARIN AND NAPA FROM 4 AM
FRIDAY MORNING TO 1 PM FRIDAY AFTERNOON.
RAINFALL TOTALS THUS FAR HAVE BEEN ANYWHERE FROM HALF AN INCH TO
NEARLY 1.5 INCHES IN THE NORTH BAY TO HALF AN INCH TO 1.25 INCHES IN
THE SANTA CRUZ MOUNTAINS. WE HAVENT EVEN SEEN HALF OF THE RAINFALL
WE ARE GOING TO GET WITH THIS STORM. RAINFALL TOTALS WILL CONTINUE
TO IMPRESS US THROUGH THE NEXT 48 HOURS. SOME TOTALS TO HIGHLIGHT
IN THE NORTH BAY MOUNTAINS INCLUDE OLEMA VALLEY AND HAWKEYE WHICH
REPORTED 1.12 AND 1.88 INCHES RESPECTIVELY AS OF 8 PM. SINCE THE
LAST DISCUSSION RAIN HAS SWEPT INTO THE SANTA CRUZ MOUNTAINS
DROPPING AN IMPRESSIVE 1.25 INCHES AT BEN LOMOND...1.0 INCHES IN
SCOTTS VALLEY AND 0.79 INCH IN BOULDER CREEK.
WINDS HAVE REMAINED STEADY WITH SOUTH WINDS AROUND 15 TO 30 MPH WITH
GUSTS TO 50 MPH. STRONGEST WINDS HAVE BEEN OBSERVED MAINLY IN THE
HILLS WITH GUSTS AS HIGH AS 62 MPH IN THE NORTH AND EAST BAY
MOUNTAINS AS WELL AS THE SANTA CRUZ MOUNTAINS.
FROM PREVIOUS DISCUSSION...BEHIND THE FRONT...A YET EVEN STRONGER
STORM IS DEVELOPING. A RATHER IMPRESSIVE 180KT JET NEAR 140W WILL
CONTINUE TO DIG AS A RESULT A STRONG LOW PRESSURE WILL BUILD. THE
STRONG WINDS CURRENTLY ON GOING WILL REMAIN AND ACTUALLY INCREASE TO
HIGH WIND WARNING LEVELS(SEE SFONPWMTR) OR 25 TO 45 MPH WITH GUSTS TO
60 MPH PLUS IN THE HILLS WITH THE APPROACHING SECOND SYSTEM. ALSO...
AS THE LOW DEEPENS(960MB) OFF THE PACNW COAST AND THE NOSE OF A 140KT
MOVES OVER NORCAL...LIFT INCREASES DRAMATICALLY LATE TONIGHT/EARLY
TOMORROW. THIS WILL LIKELY BE THE PERIOD OF THE HIGHEST RAINFALL
RATES(08Z-20Z). IN FACT...SIX HOURLY RAINFALL RATES EARLY FRIDAY WILL
LIKELY BE IN EXCESS OF 2 INCHES IN TERRAIN FAVORED AREAS.
ELSEWHERE...1 TO 2 INCHES WILL LIKELY BE THE NORM. AS THE COLD FRONT
MOVES ONSHORE MIDDAY FRIDAY...LOW LEVEL SHEAR...LAPSE RATES AND SFC
CAPE ALL INCREASE COMBINED WITH THE VERTICAL VELOCITIES/COOL AIR
ALOFT WILL MAKE IT POSSIBLE FOR THUNDER. HAVE ADDED THUNDER TO THE
FORECAST FRIDAY AND FRIDAY EVENING. BY LATE FRIDAY...THE INTENSE
RAINFALL SHOULD DIMINISH...BUT SHOWERS WILL REMAIN FRIDAY NIGHT.
FOR SATURDAY/SATURDAY NIGHT...THE HEART OF THE COLD AIR ASSOCIATED
WITH UPPER TROUGH WILL MOVE OVERHEAD FURTHER DESTABILIZING THE
AIRMASS. THEREFORE...WILL CONT THE MENTION OF THUNDER. PRECIP
AMOUNTS WILL NOT BE AS HIGH AS THE FRIDAY SYSTEM AND SHOULD BE
MORE SHOWER LIKE IN NATURE...BUT STILL MEASURABLE. SNOW LEVELS WILL
ALSO LOWER THROUGH THIS PERIOD...BUT NOT LOW ENOUGH TO MENTION FROZEN
PRECIP YET. THIS WILL HAVE TO BE MONITORED OVER THE NEXT DAY.
YET ANOTHER STORM SYSTEM WILL MOVE IN ON SUNDAY CONTINUING THE
CHANCE OF SHOWERS.
LONG TERM(MONDAY-THURSDAY)...
NO REAL BREAK IN AN ACTIVE WEATHER PATTERN IS EXPECTED DURING THE
EXTENDED. LATEST MEDIUM RANGE MODELS CONTINUE TO SHOW AN ACTIVE
STORM TRACK OVER MUCH OF THE WEST COAST. THE SYSTEM SLATED FOR
TUESDAY INTO WEDNESDAY LOOKS TO BE GAINING SOME STRENGTH WITH
ANOTHER ROUND OF DECENT RAIN. HAVE INCREASED POPS TUESDAY AND
WEDNESDAY. THERE AFTER...HIGH PRESSURE TRIES TO BUILD LATE IN THE
PERIOD.
