AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HONOLULU HI
1000 AM HST FRI FEB 27 2009

.UPDATE...
WE HAVE UPDATED THE FORECASTS TO ISSUE A GALE WARNING FOR THE
ALENUIHAHA CHANNEL...CANCEL THE WIND ADVISORY FOR MAUNA KEA AND
MAUNA LOA AND TO DECREASE THE PROBABILITY OF SHOWERS FOR ALL ISLANDS.

&&

.SYNOPSIS...
HIGH PRESSURE TO THE NORTH WILL KEEP MAINTAIN TRADE WINDS OVER THE
ISLANDS THROUGH NEXT WEEK. THE HIGH PRESSURE IS QUITE STRONG...SO
THERE WILL BE WIDESPREAD BREEZY CONDITIONS AND IT WILL BE LOCALLY
WINDY. THE ATMOSPHERE IS DRY AND STABLE SO RAINFALL WILL BE QUITE
SPARSE.

&&

.DISCUSSION...
A VERY STRONG HIGH...WITH A CENTRAL PRESSURE AROUND 1048 MB...SITS
NORTH OF THE ISLANDS. A TIGHT PRESSURE GRADIENT SOUTH OF THE HIGH
WILL MAINTAIN STRONGER THAN NORMAL NORTHEAST TRADE WINDS OVER THE
ISLANDS. THE GFS MODEL SHOWS THE STRONGEST TRADES TODAY THROUGH
SUNDAY AND AGAIN ON TUESDAY...BUT THE TRADES WILL BE BREEZY THROUGH
MOST OF NEXT WEEK. STRONG NORTHWEST WINDS THAT HAD BEEN BLOWING OVER
MAUNA KEA AND MAUNA LOA HAVE TAPERED OFF BUT THE STRONG WINDS MAY
SPREAD UP TO HIGHER ELEVATIONS OVER THE WEEKEND SO A WIND ADVISORY
MAY BE NEEDED FOR HALEAKALA.

THE TRADE WINDS WILL CARRY SOME SHOWERS OVER THE ISLANDS BUT THE
ATMOSPHERE IS DRY AND STABLE...SO RAINFALL WILL BE LIGHT. WHAT
SHOWERS THAT DO OCCUR WILL BE MOST ACTIVE NIGHTS AND MORNINGS...
FOCUSED MAINLY OVER WINDWARD AREAS. SINCE THE WINDS ARE SO STRONG
ISOLATED SHOWERS WILL SPREAD LEEWARD ON THE SMALLER ISLANDS.

ALTHOUGH TEMPERATURES HAVE NOT BEEN EXCEPTIONALLY LOW...STRONG WINDS
AND LOW HUMIDITIES ARE MAKING IT FEEL CHILLY. THOSE CONDITIONS WILL
CONTINUE THROUGH AT LEAST EARLY NEXT WEEK.

&&

.MARINE...
A QUIKSCAT PASS THIS MORNING SHOWED SOME 35 KT WINDS IN THE
ALENUIHAHA CHANNEL SO WE HAVE UPGRADED THE SMALL CRAFT ADVISORY TO A
GALE WARNING FOR THE ALENUIHAHA CHANNEL. WITH STRONG TRADE WINDS AND
ROUGH SEAS ELSEWHERE...THE SMALL CRAFT ADVISORY WILL CONTINUE.
ALSO...A HIGH SURF ADVISORY CONTINUES FOR EAST FACING SHORES OF ALL
THE ISLANDS. THE THREAT FOR MODERATE HARBOR SURGES AT KAHULUI AND
HILO HARBORS WILL ALSO CONTINUE.

&&

.HFO WATCHES/WARNINGS/ADVISORIES...
GALE WARNING UNTIL 6 PM SATURDAY FOR THE ALENUIHAHA CHANNEL.

SMALL CRAFT ADVISORY UNTIL 6 AM HST MONDAY FOR ALL OTHER HAWAIIAN
WATERS.

HIGH SURF ADVISORY UNTIL 6 AM HST MONDAY FOR EAST FACING SHORES OF
ALL ISLANDS.
