AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HONOLULU HI
1040 AM HST TUE SEP 29 2009

UPDATED WWA SECTION

.SYNOPSIS...
A LARGE SURFACE HIGH LOCATED FAR NORTH NORTHEAST OF HAWAII WILL
CONTINUE TO PRODUCE BREEZY TRADE WINDS THROUGH THE WEEK. STABLE
ATMOSPHERIC CONDITIONS WILL LIMIT MOST OF THE SHOWERS TO WINDWARD
AND MAUKA LOCATIONS. THERE WILL BE A SLIGHT INCREASE IN TRADE
SHOWERS ACROSS PARTS OF THE STATE LATER THIS WEEK.

&&

.DISCUSSION...
MODERATE TRADE WINDS CONTINUE ACROSS THE ISLANDS THIS MORNING
BRINGING A FEW SHOWERS TO MAINLY WINDWARD AND MOUNTAIN AREAS.
RAINFALL AMOUNTS HAVE REMAINED ON THE LIGHT SIDE WITH GENERALLY LESS
THAN .10 OF AN INCH AT THE AUTOMATED RAIN GAGE NETWORK.

IN THE SHORT TERM...THE LARGE 1039 MB HIGH CENTERED FAR NORTHEAST OF
THE STATE IS RESPONSIBLE FOR THE MODERATE TRADE WINDS...AND THIS
HIGH IS EXPECTED TO REMAIN IN THIS POSITION THROUGH TODAY.
CONTINUED TRADE FLOW WILL BRING SCATTERED CLOUDS SEEN UPSTREAM OF
THE ISLANDS ON SATELLITE IMAGERY ACROSS WINDWARD AND MAUKA LOCATIONS
TODAY.

FOR THE REST OF THE WEEK...THE HIGH IS FORECAST TO REMAIN NORTHEAST
OF THE STATE BUT WEAKEN SLOWLY THURSDAY AND FRIDAY. THE MODELS SHOW
AN INCREASE OF MOISTURE OVER THE ISLANDS...SO TRADE SHOWERS WILL BE
A LITTLE MORE PERSISTENT OVER WINDWARD AND MAUKA AREAS THURSDAY AND
FRIDAY.

OVER THE WEEKEND...THE GLOBAL MODELS SHOW A COLD FRONT AND TROUGH
DROPPING TO THE NORTHWEST OF THE STATE. THE MODELS DIVERGE LATE IN
THE WEEKEND AND EARLY NEXT WEEK WITH THE STRENGTH AND POSITION OF
THE FRONT. THE GFS IS THE STRONGEST WITH THE FRONT AND TROUGH JUST
NORTHWEST OF KAUAI...BRINGING SOUTH WINDS TO THE ISLANDS. THE EC
HAS A VERY WEAK FRONT FURTHER NORTHWEST OF KAUAI...KEEPING LIGHT
EAST TO SOUTHEAST WINDS OVER THE ISLANDS. WILL KEEP FORECAST
TRENDED TOWARDS THE MORE TRUSTED ECM FOR THE WEEKEND AND EARLY NEXT
WEEK...WITH WINDS BECOMING LIGHT AND INCREASING MOIST CONVECTION.

&&

.MARINE...
A SMALL CRAFT ADVISORY...SCA...REMAINS IN EFFECT FOR THE WINDIER
COASTAL WATERS AND CHANNELS ADJACENT TO MAUI AND THE BIG ISLAND. THE
SCA WILL LIKELY BE EXTENDED FOR THESE MARINE ZONES THROUGH THE REST
OF THIS WEEK. ADDITIONAL MARINE ZONES...SUCH AS THE KAIWI AND KAUAI
CHANNELS...MAY ALSO NEED TO BE INCLUDED IN THE SCA BY THURSDAY OR
FRIDAY WHEN THE PRESSURE GRADIENT ACROSS THE STATE MAY TIGHTEN
SLIGHTLY.

A SHORT PERIOD NORTHEAST SWELL ORIGINATING FROM THE RELATIVELY LONG
FETCH OF 20 TO 25 KT WINDS ALONG THE EASTERN PERIPHERY OF THE LARGE
HIGH TO THE NORTH NORTHEAST OF THE STATE WILL ARRIVE WEDNESDAY. THIS
SWELL...ALONG WITH LOCALLY GENERATED TRADE WIND WAVES...WILL LIKELY
RESULT IN ROUGH AND CHOPPY SURF ALONG EAST FACING SHORES OF MOST
ISLANDS. SURF HEIGHTS MAY APPROACH THE HIGH SURF ADVISORY THRESHOLD
OF 8 FEET FOR EAST FACING SHORES OF SOME ISLANDS BY FRIDAY OR
SATURDAY.

&&

.FIRE WEATHER...
SIMILAR TO YESTERDAY...BREEZY TRADE WINDS WITH RELATIVE HUMIDITY
VALUES JUST MARGINALLY TOO MOIST FOR RED FLAG WARNINGS ARE
EXPECTED. MORNING TRENDS AND NUMERICAL GUIDANCE SUGGESTS THAT
MINIMUM HUMIDITIES WILL BE IN THE 45 TO 48 PERCENT RANGE AT HNL.
GUIDANCE SHOWS THE FORECAST PARAMETERS FOR WEDNESDAY AS LITTLE
CHANGE TO THE TRADE WIND SPEEDS...AND A SLIGHT INCREASE IN RELATIVE
HUMIDITY VALUES BY 2 OR 3 PERCENT. OVERALL...NOT MUCH CHANGE IN FIRE
WEATHER CONDITIONS EXPECTED THROUGH WEDNESDAY.

&&

.HFO WATCHES/WARNINGS/ADVISORIES...
TSUNAMI ADVISORY ALL COASTAL AREAS TODAY UNTIL 700 PM.

SMALL CRAFT ADVISORY UNTIL 600 PM HST WEDNESDAY FOR THE PAILOLO AND
ALENUIHAHA CHANNELS...MAALAEA BAY AND THE WATERS SOUTH OF THE BIG
ISLAND.
