..FAUSTO TO TRACK NORTH THE ISLANDS BY MIDWEEK
THE WEATHER PATTERN FOR THE STATE INTO TUESDAY WILL BE DOMINATED
BY THE INFLUENCE OF STRONG HIGH PRESSURE BRIDGING TO THE NORTH OF
THE STATE. THIS WILL SUPPORT MODERATE TO STRONG/BREEZY MEAN ISLAND
TRADES. THIS PATTERN WILL FOCUS LIMITED MOISTURE AND RAINFALL
CHANCES MAINLY INTO WINDWARD TERRAIN UNDER RIDGING ALOFT.
MEANWHILE, PER THE LATEST TRACK FROM THE NATIONAL HURRICANE
CENTER, HURRICANE FAUSTO IS FORECAST TO MAINTAIN A STEADY WNW
TRAJECTORY TOWARDS HAWAII, AGAIN EXPECTED TO WEAKEN TO A TROPICAL
STORM AND PASS NORTH OF THE EASTERN AND CENTRAL ISLANDS LATER
TUESDAY AFTERNOON INTO WEDNESDAY MORNING, WHILE PASSING NORTH OF
KAUAI BY LATE WEDNESDAY. THE GUIDANCE AND OFFICIAL NHC FORECAST
TRACK OF FAUSTO HAS TRENDED TOWARD A TRACK FARTHER NORTH OF THE
ISLANDS OVER THE PAST DAY OR SO. THEREFORE, CONTINUE TO EXPECT A
RELATIVELY SHORT-LIVED DISRUPTION TO THE NORMAL EAST-NORTHEASTERLY
TRADES BY TUE-WED WITH THE PASSAGE OF FAUSTO TO THE NORTH. WHILE
THE BULK OF THE MOISTURE ASSOCIATED WITH FAUSTO'S CDO REMAINS
NORTH OF THE ISLANDS, DEEPENING SOUTH-SOUTHEASTERLY FLOW OVER THE
ISLANDS (SOUTHERN PERIPHERY OF FAUSTO'S CIRCULATION) WILL AT LEAST
TEMPORARILY DRAW IN MUCH HIGHER PWS ALONG WITH MORE NUMEROUS
SHOWERS AND ACCOMPANYING GUSTY WINDS WITHIN FAUSTO'S SOUTHERN
OUTER BANDS. THE GOOD NEWS IS THAT THE POTENTIAL FOR HEAVY
RAINFALL WILL BE RELATIVELY SHORT-LIVED, WITH A RETURN IN THE MORE
TYPICAL EAST-NORTHEASTERLY TRADES AND ASSOCIATED WINDWARD AND
MAUKA RAINFALL DISTRIBUTION/INTENSITY BY LATE WEEK AND THROUGH
NEXT WEEKEND.
