AREA FORECAST DISCUSSION...CORRECTED
NATIONAL WEATHER SERVICE HONOLULU HI
1000 AM HST SAT FEB 2 2008

.SYNOPSIS...
WET WEATHER PREVAILS AS SCATTERED MODERATE TO HEAVY SHOWERS TRAVERSE
THE ISLANDS CARRIED BY FRESH TRADE WINDS. UNSTABLE CONDITIONS WILL
CONTINUE DUE TO AN UPPER LOW PRESSURE CENTER THAT WILL MOVE JUST
SOUTHWEST OF KAUAI. TRADE WINDS WILL WEAKEN SOMEWHAT SUNDAY AND
MONDAY AND THEN MORE TYPICAL TRADE WIND WEATHER SHOULD RETURN BY THE
FIRST PART OF NEXT WEEK.

&&

DISCUSSION...
THE UPPER LOW AND PROXIMITY OF THE JET STREAM ARE EXPECTED TO
CONTINUE PRODUCING INSTABILITY AND PROLONGING THE WET WEATHER. THE
UPPER LOW WILL SHIFT SOUTHWEST KAUAI AND GFS MODEL DEPICTS SHORT
WAVES ROTATING AROUND THE BASE OF THE LOW AND OVER OUR ISLANDS
THROUGH SUNDAY. MOISTURE AND CONVERGENCE THROUGH THE LOWER HALF OF
THE ATMOSPHERE WILL CONTINUE TO FUEL THE SCATTERED MODERATE TO
LOCALLY HEAVY SHOWERS OR THUNDERSTORMS THROUGH SUNDAY. DYNAMICS
WEAKEN SOMEWHAT MONDAY BUT POPS FOR THE BIG ISLAND WILL BE INCREASED
MONDAY DUE TO JET STREAM CORE REMAINING OVER THAT AREA AND CONTINUED
MODERATE PRECIPITATION DEPICTED BY MODELS. THERE IS CONSIDERATION
OF A FLASH FLOOD WATCH FOR ENTIRE STATE THIS WEEKEND BUT UNDER
THESE CONDITIONS OF MODERATE TRADE WIND FLOW THE HEAVY
PRECIPITATION TYPICALLY WILL CONTINUE MOVING ACROSS ISLANDS. THE
EXCEPTION HOWEVER ARE CERTAIN LOCATIONS WHERE ECHOS MAY CONTINUE
TRAINING OVER THE SAME SPOT. AS OF LATE MORNING THE BIG ISLAND AND
EAST MAUI CONTINUE ON THE RECEIVING END OF THE WESTWARD MOVING
SHOWERS. HEAVY SHOWERS HAVE MOVED ACROSS MAUI AND OAHU THROUGH THE
MORNING AND MAY BEGIN INCREASING THIS AFTERNOON OVER KAUAI. SERIOUS
FLOODING HAS OCCURRED OVER PART OF THE NORTHEAST BIG ISLAND AND
ESPECIALLY AROUND HILO WHERE RAIN GAGES HAVE REPORTED 12 HOUR
AMOUNTS OF THREE TO FIVE INCHES AND AS MUCH AS 9 INCHES AT WAIAKEA
UKA ENDING AT 8 AM.

THE WINTER WEATHER ADVISORY FOR THE BIG ISLAND SUMMITS HAS BEEN
EXTENDED THROUGH SUNDAY MORNING BUT THERE IS STILL THE EXPECTATION
OF SOUTHERLY ADVECTION OF WARMER AIR RAISING THE FREEZING LEVEL.

THE STRONG SURFACE HIGH TO THE NORTH WILL WEAKEN GRADUALLY AS IT
SHIFTS EASTWARD THEREFORE SLOW DECREASE IN TRADES EXPECTED THROUGH
THE NEXT FEW DAYS... BECOMING LIGHT TO MODERATE BY MID WEEK. WINDS
ARE JUST STRONG ENOUGH TO EXTEND GALES OVER WINDIER CHANNELS AND
SMALL CRAFT ADVISORIES FOR REMAINING AREAS THROUGH SUNDAY MORNING.
SIMILARLY THE TRADE WIND DRIVEN SHORT PERIOD EAST SWELL IS
DECREASING SLOWLY AND MAY LINGER INTO MONDAY.
