HAWAII EXTENDED FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
335 AM EDT FRI JUL 14 2023
VALID 00Z SAT JUL 15 2023 - 00Z SAT JUL 22 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 WEDNESDAY AND THURSDAY, WHAT IS NOW HURRICANE
CALVIN WILL LIKELY TRACK TOWARDS THE GENERAL DIRECTION OF THE BIG
ISLAND AS A TROPICAL STORM 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 STRONG WINDS. AS THE SYSTEM
CONTINUES TO WEAKEN, LIGHTER IMPACTS ARE LIKELY FOR THE CENTRAL
AND WESTERN ISLANDS.
