EXCESS OF 21 INCHES AS OF 2 PM. COASTAL WATERS NORTHWEST OF KAUAI

KAUAI FRIDAY NIGHT. IT WILL THEN MOVE DOWN THE ISLAND CHAIN TO EAST
OF THE BIG ISLAND BY SATURDAY NIGHT. THE MOIST AIR WILL SHIFT TO THE
EAST IN ADVANCE OF THE FRONT.

INSTABILITY ASSOCIATED WITH AN UPPER LEVEL TROUGH NORTHWEST OF THE
STATE WILL SET OFF HEAVY SHOWERS AND THUNDERSTORMS IN THE MOIST AIR
AHEAD OF THE FRONT. THE TROUGH IS FORECAST TO MOVE TO THE SOUTHEAST
AND IS EXPECTED TO BE EAST OF THE ISLANDS SATURDAY NIGHT. THE FLASH
FLOOD WATCH PRESENTLY IN EFFECT FOR NIIHAU...KAUAI AND OAHU WILL

THE ISLANDS FROM THE WEST RESULTING IN A MORE STABLE ATMOSPHERE.

THE LARGE NORTH SWELL. SEAS WILL DECREASE BELOW SCA CRITERIA TONIGHT
FOR MOST COASTAL WATERS. HOWEVER...INCREASING SOUTH TO SOUTHWEST
WINDS...AS WELL AS LARGER SEAS DUE TO LOCALLY GENERATED WIND
WAVES...WILL REQUIRE THE SCA TO REMAIN IN EFFECT THROUGH FRIDAY

WITH PREVAILING MVFR/IFR CIGS AND VIS. LOCAL LIFR CONDITIONS ARE
