THE LONG PERIOD WESTERLY SWELL WILL SUBSIDE TO BELOW 10 FEET THIS
EVENING. 

A COLD FRONT WILL APPROACH TUESDAY WITH RAPIDLY INCREASING
SOUTHERLY WINDS OF 20 TO 30 KT WITH GUSTS TO 35 KT AHEAD OF IT
DURING THE LATE MORNING AND AFTERNOON. THE WINDS WILL RAPIDLY EASE
AFTER THE FRONTAL PASSAGE LATE TUESDAY EVENING.

&&


PRECAUTIONARY/PREPAREDNESS ACTIONS...

A GALE WARNING MEANS WINDS OF 34 TO 47 KNOTS ARE IMMINENT OR
OCCURRING. OPERATING A VESSEL IN GALE CONDITIONS REQUIRES
EXPERIENCE AND PROPERLY EQUIPPED VESSELS. IT IS HIGHLY
RECOMMENDED THAT MARINERS WITHOUT THE PROPER EXPERIENCE SEEK SAFE
HARBOR PRIOR TO THE ONSET OF GALE CONDITIONS.

A SMALL CRAFT ADVISORY FOR HAZARDOUS SEAS MEANS THAT WAVES ARE
EXPECTED TO BE HAZARDOUS TO SMALL CRAFT. MARINERS SHOULD AVOID
SHOALING AREAS. LONG PERIOD SWELL CAN SHARPEN INTO LARGE BREAKING
WAVES IN SHOALING AREAS. IT IS NOT UNUSUAL FOR WAVES TO BREAK
MUCH FARTHER FROM SHOALING AREAS THAN IS NORMALLY EXPERIENCED.
REMEMBER...BREAKING WAVES CAN EASILY CAPSIZE EVEN LARGER VESSELS.

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE EUREKA CA
810 AM PST SUN DEC 27 2009

.SYNOPSIS...A LOW PRESSURE SYSTEM WILL CONTINUE TO GENERATE SHOWERS
OVER NORTHWEST CALIFORNIA TODAY AND THIS EVENING. A COLD FRONT WILL
BRING ANOTHER CHANCE OF RAIN TUESDAY AND TUESDAY NIGHT.

&&

.UPDATE...FCST IN GOOD SHAPE THIS MORNING...JUST A QUICK UPDATE TO
REFINE PRECIP COVERAGE AND TIMING A BIT. THE LOW THAT IS CAUSING
THE PRECIP THIS MORNING IS CURRENTLY NEAR 43N 130W AND IS EXPECTED
TO FILL AND SLOWLY LIFT NE. ADDITIONALLY...AN NEGATIVELY TILTED
SHORTWAVE JUST OFF OF CAPE MENDOCINO WILL LIFT NE ALSO. BOTTOM
LINE...THE BAND OF SHOWERS CURRENTLY LIFTING THROUGH THE AREA WILL
ALSO LIFT NE WITH SHOWERS BEHIND THE MAIN BAND...CONFINED MAINLY
NORTH OF THE CAPE. SNOW LEVELS ARE CURRENTLY RUNNING 3000-3500 FT
WITH REPORTS OF 3 INCHES AT SOUTHFORK MTN AT 4300 FT. JCA

&&

.PREV DISCUSSION... /ISSUED 241 AM PST SUN DEC 27 2009/

.DISCUSSION...A SURFACE LOW NEAR 43N 132W WILL CONTINUE TO PRODUCE
SHOWERS ACROSS NORTHERN CA TODAY. SLIGHT NEGATIVE TILTING OF THE
TROUGH ASSOCIATED WITH THE LOW SUGGESTS INSTABILITY WITH A FEW
THUNDERSTORMS POSSIBLE THIS MORNING AND EARLY AFTERNOON. THE LOW
WILL WEAKEN AND SLOWLY MOVE NE TODAY AND TONIGHT WITH SHOWERS
TAPERING OFF IN THE AFTERNOON...AND BECOMING ISOLATED BY THE
EVENING. THE LOW WILL ADVECT COOLER AIR OVER THE REGION TONIGHT
WITH SNOW LEVELS DROPPING TO NEAR 3500 FEET...BUT DO NOT
ANTICIPATE MUCH IF ANY SNOW ACCUMULATION SINCE THE SHOWERS WILL
DECREASE IN COVERAGE AND INTENSITY BEFORE THE COOLER AIR ARRIVES.
ISOLATED SHOWERS MAY CONTINUE NORTH OF CAPE MENDOCINO INTO MON
MORNING AS THE SOUTHERN PORTION OF THE TROUGH SWINGS ACROSS NE CA.

MODELS ARE IN BETTER AGREEMENT ON THE NEXT RAIN PRODUCER EXPECTED ON
TUESDAY. DECENT ISENTROPIC LIFT AND GFS MODELED PRECIPITABLE WATER
SUGGEST THAT THE FRONT MAY GENERATE MORE PRECIPITATION THAN
PREVIOUSLY THOUGHT. HAVE INCREASED POPS AND QPF SLIGHTLY FOR TUE AND
TUE NIGHT...AND WOULD NOT BE SURPRISED IF THIS UPWARD TREND
CONTINUES THE NEXT COUPLE OF SHIFTS.

AN UPPER LEVEL RIDGE WILL MOVE OVER THE NE PACIFIC MID WEEK...BUT
THE MODELS ARE CONSISTENT IN FORECASTING A SURFACE FRONT TO UNDERCUT
THE RIDGE LATE IN THE WEEK AND HAVE MAINTAINED CHANCE POPS INTO THE
WEEKEND. TH

&&

.AVIATION....MAINLY VFR CONDITIONS TO PREVAIL TODAY...ALTHOUGH
OCCASIONAL MVFR CEILINGS AND VISIBILITIES CAN BE EXPECTED IN RAIN
SHOWERS. THERE WILL CONTINUE TO BE PROLONGED DRY PERIODS...FEATURING
VFR CEILINGS AND UNRESTRICTED VISIBILITIES. RAIN SHOWER
ACTIVITY...ALONG WITH SOME LOCALLY GUSTY WINDS...WILL DIMINISH AFTER
00Z. A GENERAL IMPROVEMENT IN FLYING CONDITIONS CAN BE EXPECTED
TONIGHT...ALTHOUGH AREAS OF FOG MAY FORM LATE. BETTWY

&&

.MARINE...SOUTH-SOUTHEAST WINDS HAVE REMAINED GENERALLY JUST UNDER
SMALL CRAFT CRITERIA ACROSS THE INNER WATERS FOR THE PAST SEVERAL
HOURS...AND WE EXPECT WINDS SPEEDS TO BEGIN TO SLOWLY SLACKEN OVER
THE OUTER WATERS BY DAYBREAK AS A COLD FRONT PUSHES EAST. THE CLOSED
LOW IN ASSOCIATION WITH THE FRONT WILL CONTINUE TO MEANDER OR SLOWLY
PUSH NORTHEAST AWAY FROM OUR WATERS THROUGH MONDAY...GENERALLY
RESULTING IN CONTINUED CHANCES FOR RAIN SHOWERS...SOME THAT COULD BE
QUITE CONVECTIVE AND OCCASIONALLY HEAVY. A FEW THUNDERSTORMS WILL
ALSO BE POSSIBLE...ESPECIALLY THROUGH MIDDAY TODAY. OTHERWISE...THE
LONG PERIOD WESTERLY SWELL WILL CONTINUE TO TRAVERSE THROUGH WATERS
AND BEGIN TO SUBSIDE TONIGHT. THE MODELS ARE STILL HIGH WITH ACTUAL
SWELL HEIGHTS...AND WE MAINTAINED SLIGHTLY LOWER VALUES.
HOWEVER...LARGE BREAKERS UP TO 18 FEET WILL STILL BE POSSIBLE
THROUGH THE DAY.  BETTWY
