PRECAUTIONARY/PREPAREDNESS ACTIONS...

A GALE WARNING MEANS WINDS OF 34 TO 47 KNOTS ARE IMMINENT OR

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
NATIONAL WEATHER SERVICE EUREKA CA
317 PM PDT THU APR 23 2009

.SYNOPSIS...A TROUGH WILL MOVE INTO THE WEST COAST TONIGHT INTO
FRIDAY...BRINGING COOLER TEMPERATURES AND THE SLIGHT CHANCE OF
SHOWERS AND THUNDERSTORMS INLAND FRIDAY AFTERNOON AND EVENING. DRY
CONDITIONS WILL PREVAIL THROUGH THE WEEKEND.

&&

.DISCUSSION...A TROUGH IS CURRENTLY MOVING OVER THE WEST COAST AND
WILL CONTINUE TO MOVE FURTHER OVERHEAD INTO FRIDAY, SKIES WILL BE
PARTLY CLOUDY TONIGHT WITH FAIRLY LIGHT WINDS. HAVE HELD OFF ON
ISSUING ANY FROST ADVISORIES BECAUSE DO NOT BELIEVE WE WILL HAVE
WIDESPREAD TEMPERATURES IN THE LOW TO MID 30S FOR A FEW HOURS. BUT
THE LOCAL COLD SPOTS COULD SEE SOME FROST.

TEMPERATURES WILL BE COOLER FRIDAY AS THE TROUGH AXIS MOVES
OVERHEAD. THERE WILL BE THE SLIGHT CHANCE OF SOME AFTERNOON SHOWERS
AND THUNDERSTORMS INLAND. TEMPERATURES WILL NOT BE TOO HOT...60S
INLAND...SO INSTABILITY WILL NOT BE STRONG. THEREFORE AM NOT TOO
OPTIMISTIC ON SEEING THUNDERSTORMS FRIDAY BUT STILL DECIDED TO KEEP
THEM IN THE FORECAST BECAUSE ONE COULD POP UP. ANY RAIN THAT DOES
FALL WILL BE MINIMAL...LESS THAN 0.1 INCH. ANY PRECIPITATION WILL
WIND DOWN IN THE EVENING AS THE DAYTIME HEATING ENDS AND THE TROUGH
AXIS MOVES INLAND. THE WEEKEND WILL BE DRY AND COOL.

ON SUNDAY HIGH PRESSURE OVER THE EAST PACIFIC WILL BUILD WHILE BRISK
NORTHERLY FLOW CONTINUES ACROSS THE WEST COAST.  ON MONDAY A SHORT
WAVE BEGINS TO DIG TOWARD THE SOUTHERN OREGON AND NOR CAL AND WITH
IT A CHANCE OF PRECIPITATION MAINLY IN THE FORM OF RAIN BUT SNOW IS
POSSIBLE AT HIGHEST ELEVATIONS (>5K).  THE WAVE EVOLVES INTO A
CLOSED CIRCULATION OVER WYOMING WHILE EMBEDDED VORT MAXES CONTINUE
TO SPIN OVER THE CWA THROUGH THURSDAY...THUS HAVE KEPT A CHANCE OF
SHOWERS TO REFLECT THIS THROUGH THURSDAY. THE THREAT OF RAIN THROUGH
THIS PERIOD WILL BE ACCOMPANIED BY A 8 TO 12 DEGREE DROP IN
TEMPERATURES MAINLY OBSERVED ACROSS THE INTERIOR. MS/JT

&&

.AVIATION...A DRIER NORTHERLY FLOW WILL BRING PREDOMINATE VFR CONDITIONS
TO ALL AIR TERMINALS THROUGH THE NEXT TAF CYCLE. THERE IS A CHANCE
OF SOME LOCALIZED STRATUS AND PATCHY FOG DURING THE EARLY MORNING HOURS
ALONG THE NORTH COAST BUT HIGH RESOLUTION GUIDANCE INDICATES A LOW
PROBABILITY OF THAT OCCURRING.

&&

.MARINE...GALE FORCE WIND CONDITIONS WILL CONTINUE THROUGHOUT ALL
EUREKA COASTAL WATERS THOUGHT THIS EVENING...HOWEVER WINDS WILL
REMAIN BRISK INTO NEXT WEEK AND WILL POSE A THREAT TO SMALL CRAFT IN
COASTAL WATERS.  THE WINDS WILL GENERATE SHORT PERIOD WIND WAVES IN
THE WATERS OF UP TO 7 FEET FOR THE NEXT WEEK. LOCALLY RUN MODELS
INDICATE THE PRESENCE OF A SMALL SOUTHWEST SWELL OF AROUND 1 TO 3
FEET AT 18 SECONDS...DIMINISHING TO 12 SECONDS BY NEXT WEEK.
HOWEVER...THIS SWELL FROM THE OUTSIDE OUR WATERS WILL BE DWARFED BY
THE LOCALLY GENERATED FRESH SWELL.  MSB

&&

.EKA WATCHES/WARNINGS/ADVISORIES...

CA...NONE.

GALE FROM PT ST GEORGE TO PT ARENA 10 TO 60 NM.
