...HEAVY RAINS FOR THE WESTERN HAWAIIAN ISLANDS SATURDAY NIGHT
THROUGH WEDNESDAY...
A COLD FRONT THAT IS THROUGH KAUAI OVERNIGHT DRIFTS EAST, REACHING
MAUI LATE TODAY BEFORE DIMINISHING. THIS FRONT WEAKENS THE TRADES,
BUT PROVIDES SOME FOCUS FOR BRIEFLY HEAVY RAINFALL ALONG THE
BOUNDARY.
A LOW PRESSURE SYSTEM TRACKS EAST ALONG 30N STARTING FRIDAY WITH
THE ATTENDANT COLD FRONT REACHING THE WESTERN MAIN ISLANDS
SATURDAY NIGHT THEN STALLING INTO MONDAY. HEAVY RAIN CAN BE
EXPECTED ALONG THIS FRONTAL ZONE WHICH LIFTS NORTH AHEAD OF THE
NEXT WAVE THAT BRINGS ANOTHER FRONTAL ZONE TO THE WESTERN MAIN
ISLANDS THEN THROUGH WEDNESDAY IF NOT LONGER. CONTINUED CONFIDENCE
IN A PROLONGED HEAVY RAIN EVENT. IF ANYTHING, DROUGHT RELIEF CAN
BE EXPECTED OVER THE NEXT WEEK FOR ALL BUT THE BIG ISLAND WHICH
LOOKS TO STAY EAST OF THE FRONTAL ZONES.
