NWS Honolulu, HI wrote its last area forecast discussion before this flash flood warning went out at Feb 26, 8:45 PM HST, 3 hours 30 minutes earlier.

HAWAIIAN ISLANDS FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HONOLULU HI
845 PM HST THU FEB 26 2004

.SYNOPSIS...
STRONG WINDS...HEAVY SHOWERS AND THUNDERSTORMS ARE EXPECTED ALONG
AND AHEAD OF A COLD FRONT THROUGH FRIDAY. THE FRONT WILL CROSS KAUAI
FRIDAY MORNING...OAHU BY AFTERNOON...AND MAUI COUNTY EARLY TONIGHT.
FRESH AND COOLER NORTH WINDS ARE FORECAST BEHIND THE FRONT.

&&

.DISCUSSION...
TIMING OF THE COLD FRONT STILL LOOKS REASONABLE. THE FRONT IS ABOUT
240 MILES NORTHWEST OF KAUAI AND MOVING TO THE SOUTHEAST AT AROUND
25 MPH. IT WILL LIKELY MAINTAIN THIS SPEED...ENDING UP ON KAUAI
FRIDAY MORNING...OAHU AROUND MIDDAY...THEN INTO MAUI COUNTY IN THE
AFTERNOON AND EVENING. THE FRONT IS ATTACHED TO A DEVELOPING LOW
LOCATED ABOUT 650 MILES NORTHWEST OF KAUAI. THE LOW WILL MOVE OFF TO
THE NORTHEAST...BUT WILL STILL BE CLOSE ENOUGH TO MAKE FOR A VERY
ACTIVE FRONTAL PASSAGE WITH LOTS OF HEAVY RAIN AND THUNDER.

THOUGH STILL LIGHT...THE SOUTHERLY WINDS WILL PICK UP AS THE FRONT
NEARS. THE STRONGEST WINDS WILL OCCUR WITHIN ABOUT 150 MILES EAST OF
THE FRONT...STARTING SEVERAL HOURS BEFORE FRONTAL PASSAGE.

THE MODELS ARE NOW MOVING AN UPPER LOW NORTH OF THE STATE RATHER
THAN DIRECTLY OVERHEAD AS WAS THE CASE YESTERDAY. THIS MEANS THAT
MID-LEVEL TEMPERATURES MAY NOT BE AS COLD AS EARLIER THOUGHT. IF THE
MODELS ARE INDEED CORRECT...WE MAY BE ABLE TO BACK OFF ON THE
POST-FRONTAL ISOLATED THUNDERSTORMS SATURDAY.

&&

.MARINE...
A NORTHWEST SWELL GENERATED BY A LARGE LOW NEAR THE KAMCHATKA
PENINSULA WILL ARRIVE NEAR KAUAI TONIGHT AND SPREAD DOWN THE CHAIN
FRIDAY. A HIGH SURF ADVISORY IS IN EFFECT...BUT THE SWELL IS
EXPECTED TO RISE HIGH ENOUGH TO WARRANT THE ISSUANCE OF A
HIGH SURF WARNING FRIDAY NIGHT AND SATURDAY.

&&

.HFO WATCHES/WARNINGS/ADVISORIES...
HIGH WIND WATCH THROUGH FRIDAY FOR ALL ISLANDS
FLOOD WATCH THROUGH FRIDAY FOR ALL BUT THE BIG ISLAND
HIGH SURF ADVISORY FOR ALL NORTH AND WEST FACING SHORES
