High Surf in Hawaii, August 14 to 16, 2003

HAWAIIAN ISLANDS SYNOPTIC DISCUSSION AND GUIDANCE
NATIONAL WEATHER SERVICE HONOLULU HI
10 AM HST THU AUG 14 2003

SUMMARY...BREEZY TRADE WINDS WILL CONTINUE THROUGH THE WEEKEND AS
THE MAIN HAWAIIAN ISLANDS REMAIN SANDWICHED BETWEEN HIGH PRESSURE TO
THE NORTH AND A SERIES OF TROPICAL DISTURBANCES TO THE SOUTH. TRADES
WILL DECREASE SLIGHTLY BEGINNING MONDAY. TRADE SHOWERS WILL BE
ISOLATED OVER LEEWARD AREAS AND SCATTERED OVER WINDWARD AND MAUKA
AREAS TODAY. FEWER SHOWERS ARE EXPECTED FRIDAY AND THEREAFTER.

DISCUSSION...THE SUBTROPICAL RIDGE ALONG 34N WILL REMAIN IN PLACE
FOR A FEW DAYS BEFORE STRENGTHENING AND RETREATING SLIGHTLY
NORTHEASTWARD SUNDAY. AT THE SAME TIME...A SERIES OF WEAK TROPICAL
DISTURBANCES WILL ROLL ON WESTWARD TO THE SOUTH OF HAWAII. THE
PRESSURE GRADIENT BETWEEN THE HIGH AND THE SERIES OF DISTURBANCES
WILL KEEP TRADE WINDS BREEZY ACROSS THE STATE AT LEAST THROUGH
SUNDAY. IT SEEMS THAT THE SLIGHT MOVEMENT OF THE HIGH TOWARDS THE
NORTHEAST SUNDAY WILL COUNTERACT ITS EXPECTED STRENGTHENING.
THEREFORE...TRADE WINDS WILL DECREASE INTO THE 10 TO 20 MPH RANGE
BEGINNING MONDAY IN RESPONSE TO THE SLIGHT WEAKENING OF THE PRESSURE
GRADIENT. AFTER THAT...WINDS WILL CONTINUE IN THIS SPEED RANGE
THROUGH THE REST OF THE NEXT SEVEN DAYS.

SATELLITE LOOPS SHOW BROKEN TO OVERCAST LOW CLOUDS SOUTH OF 22N
BETWEEN THE MAIN HAWAIIAN ISLANDS AND 135W. THESE CLOUDS APPEAR TO
BE RATHER STABLE...WITH UNIFORMLY WARM CLOUD TOPS NOTED IN INFRARED
IMAGERY. THESE CLOUDS WILL BLOCK THE SUN OVER WINDWARD AND MAUKA
AREAS OF THE ISLANDS FOR MUCH OF THE FORECAST PERIOD. SHOWERS WILL
BE SCATTERED OVER WINDWARD AND MAUKA AREAS OF THE SMALLER ISLANDS
TODAY...WITH FEWER SHOWERS EXPECTED TOMORROW AND THEREAFTER. LEEWARD
AREAS WILL BE CLEARER AND DRIER...ALTHOUGH THE BREEZY TRADES MAY
PUSH A SHOWER OR TWO ACROSS LEEWARD AREAS FROM TIME TO TIME.
