HAWAII EXTENDED FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
356 AM EDT SAT JUL 15 2023
VALID 00Z SUN JUL 16 2023 - 00Z SUN JUL 23 2023
THE PATTERN OVER HAWAII REMAINS RATHER STAGNANT INTO EARLY NEXT
WEEK WITH SURFACE HIGH PRESSURE ANCHORED NORTH/NORTHWEST OF HAWAII
AND AN UPPER LEVEL RIDGE EXTENDING WESTWARD OVER THE STATE FROM
THE EASTERN PACIFIC. THIS SHOULD RESULT IN MAINLY DRY WEATHER,
EXCEPT FOR THE TYPICAL TRADE WIND ENHANCED SHOWERS, AND MODERATE
TO LOCALLY BREEZY TRADE WINDS THROUGH ABOUT EARLY WEDNESDAY.
LOOKING AHEAD TO THE MIDDLE OF THE WEEK, WHAT IS NOW HURRICANE
CALVIN WILL LIKELY TRACK TOWARDS THE GENERAL DIRECTION OF THE BIG
ISLAND AS EITHER A WEAK TROPICAL STORM OR DEPRESSION BASED ON THE
LATEST FORECASTS FROM THE NATIONAL HURRICANE CENTER. THIS WOULD
RESULT IN A ROUND OF HEAVY RAINFALL FOR THE BIG ISLAND AND MAUI
FOR THE WEDNESDAY-THURSDAY TIME PERIOD, ALONG WITH HIGH SURF AND
GUSTY WINDS. SEVERAL INCHES OF RAIN IS LOOKING INCREASINGLY
LIKELY FOR PARTS OF THE BIG ISLAND WITH THIS EVENT. AS THE SYSTEM
CONTINUES TO WEAKEN, LIGHTER IMPACTS ARE LIKELY FOR THE CENTRAL
AND WESTERN ISLANDS.
