AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HONOLULU HI
830 PM HST THU MAR 23 2006

.SYNOPSIS...
A DEEP TROUGH WEST OF KAUAI WILL MAINTAIN KONA WEATHER OVER THE
ISLANDS THROUGH AT LEAST EARLY NEXT WEEK. THE TROUGH WILL KEEP
TROPICAL MOISTURE STREAMING OVER THE ISLANDS. IMPULSES MOVING OVER
THE ISLANDS FROM THE SOUTHWEST WILL KEEP THE ATMOSPHERE UNSTABLE
ENOUGH FOR HEAVY RAIN AND THUNDERSTORMS TO CONTINUE.

&&

.DISCUSSION...
SATELLITE IMAGERY AND UPPER AIR ANALYSES SHOW A DEEP NORTH NORTHEAST
TO SOUTH SOUTHWEST TROUGH NEARLY STATIONARY WEST OF KAUAI. A SERIES
OF IMPULSES KEEP DROPPING INTO THE TROUGH FROM THE NORTHWEST...
SWINGING AROUND THE TROUGH AXIS AND MOVING NORTHEASTWARD JUST WEST
OF THE MAIN HAWAIIAN ISLANDS.

LATEST SATELLITE IMAGERY SHOWS AN AREA OF LAYERED CLOUDS WITH
EMBEDDED HEAVY SHOWERS AND THUNDERSTORMS OVER THE ISLANDS FROM OAHU
TO MAUI. OVER THE PAST 6 HOUR...THIS AREA HAS BEEN MOVING TOWARDS
THE EAST NORTHEAST AROUND 20 MPH AND INTENSIFIED. THIS
INTENSIFICATION IS PROBABLY DUE TO A STRONG IMPULSE MOVING BY ABOUT
250 MILES NORTHWEST OF KAUAI. WEATHER OVER THE ISLANDS WILL REMAIN
RATHER ACTIVE OVERNIGHT BUT MAY QUIET DOWN A BIT EARLY FRIDAY
MORNING AS THE IMPULSE MOVES OFF TO THE NORTHEAST.

WEATHER OVER THE MAIN HAWAIIAN ISLANDS WILL REMAIN UNSETTLED AS LONG
AS THE TROUGH REMAINS NORTHWEST OF KAUAI. THE COMPUTER MODELS ARE
CONSISTENT IN IN KEEPING THE TROUGH THERE THROUGH NEXT MONDAY. AFTER
THAT...THE MODELS DIVERGE SIGNIFICANTLY. UNTIL THE MODELS BECOME
MORE CONSISTENT WE WILL LOOK FOR THE TROUGH TO REMAIN IN PLACE FOR
THE NEXT SEVEN DAYS.

&&

.HFO WATCHES/WARNINGS/ADVISORIES...
FLASH FLOOD WATCH THROUGH LATE FRIDAY NIGHT FOR NIIHAU KAUAI OAHU
MOLOKAI LANAI MAUI AND KAHOOLAWE.
