...FAUSTO TO TRACK NORTH THE ISLANDS LATE TUESDAY THROUGH
WEDNESDAY NIGHT...
A DISRUPTION IN THE TYPICAL TRADE WIND PATTERN IS EXPECTED OVER
THE STATE OVER THE NEXT COUPLE OF DAYS, AS HURRICANE FAUSTO
CONTINUES TO TRACK WNW AND WEAKEN TO A TROPICAL STORM AS IT
PASSES NORTH OF THE ISLANDS. THE LATEST GUIDANCE AND OFFICIAL NHC
FORECAST TRACK OF FAUSTO CONTINUES TO SUPPORT A RELATIVELY SHORT-
LIVED DISRUPTION TO THE NORMAL EAST-NORTHEASTERLY TRADES THROUGH
WEDNESDAY. MEANWHILE, DESPITE THE BULK OF THE MOISTURE ASSOCIATED
WITH FAUSTO'S CDO REMAINS NORTH OF THE ISLANDS, A BRIEF PERIOD OF
SOUTH-SOUTHEASTERLY 850-500 FLOW OVER THE ISLANDS SOUTH OF
FAUSTO'S TRACK WILL TEMPORARILY DRAW IN MUCH HIGHER PWS ALONG WITH
MORE NUMEROUS SHOWERS AND ACCOMPANYING GUSTY WINDS, ESPECIALLY
DURING PEAK DAYTIME HEATING AND ACROSS (THOUGH NOT LIMITED TO)
WINDWARD AREAS.
THE POTENTIAL FOR HEAVY RAINFALL WILL BE RELATIVELY SHORT-LIVED,
AS BY THURSDAY THE STATE WILL SEE A RETURN OF THE MORE TYPICAL
EAST-NORTHEASTERLY TRADES AND ASSOCIATED WINDWARD AND MAUKA
RAINFALL DISTRIBUTION/INTENSITY. THIS MORE STABLE PATTERN WILL
THEN PERSIST THROUGH THE WEEKEND AND INTO EARLY NEXT WEEK.
