HAWAII EXTENDED FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
234 AM EDT THU JUL 13 2023
VALID 00Z FRI JUL 14 2023 - 00Z FRI JUL 21 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 OVER THE STATE. THIS SHOULD RESULT IN DRY
WEATHER AND MODERATE TO LOCALLY BREEZY TRADE WINDS. THE LATEST
GUIDANCE CONTINUES TO SUGGEST THAT TROPICAL STORM CALVIN COULD
IMPACT HAWAII (AS A TROPICAL DEPRESSION OR A WEAK TROPICAL STORM)
AROUND TUESDAY OF NEXT WEEK WITH THE LATEST OFFICIAL TRACK FROM
THE NATIONAL HURRICANE CENTER BRINGING THE CENTER OF THE STORM
OVER THE BIG ISLAND. THERE DOES REMAIN PLENTY OF UNCERTAINTIES IN
THE DETAILS AND PLACEMENT OF THIS SYSTEM (THE CMC AND UKMET HAVE
IT PASSING JUST SOUTH OF THE BIG ISLAND), BUT REGARDLESS OF EXACT
TRACK, CONFIDENCE INCREASES THIS SYSTEM WOULD BRING GUSTY WINDS
AND HEAVY RAINFALL TO MUCH OF THE STATE, ESPECIALLY THE BIG ISLAND
AND MAUI. SEE THE LATEST INFORMATION FROM THE NATIONAL HURRICANE
CENTER FOR ADDITIONAL INFORMATION ON CALVIN.
