HAWAII EXTENDED FORECAST DISCUSSION
NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
510 AM EDT TUE SEP 1 2026
VALID 00Z WED 02 SEP 2026 - 00Z WED 09 SEP 2026
A BREEZY TRADE WIND PATTERN CONTINUES INTO WEDNESDAY AS STRONG
HIGH PRESSURE TO THE NORTH OF THE STATE REMAINS ANCHORED IN PLACE.
SHOWERS WILL MOSTLY BE LIMITED TO THE TYPICAL WINDWARD AND MAUKA
AREAS INITIALLY, THOUGH MOISTURE DRAWN IN FROM LOWELL SHOULD
INCREASE SHOWER ACTIVITY ACROSS THE ENTIRE ISLAND CHAIN THROUGH
THURSDAY AND FRIDAY, EVEN AS LOWELL TRACKS SOUTH OF THE STATE.
THIS INCREASE IN MOISTURE SHOULD ALSO ALLOW SHOWERS TO WORK INTO
THE TYPICALLY DRIER LEEWARD AREAS. AS LOWELL PASSES TO THE SOUTH,
A TIGHTENING PRESSURE GRADIENT WILL LIKELY LEAD TO STRONGER TRADE
WINDS ACROSS THE ISLAND CHAIN THROUGH AT LEAST FRIDAY. THEN ONCE
LOWELL EXITS OVER THE WEEKEND (WITH THE POTENTIAL FOR A SHARP
NORTHWARD TURN WEST OF THE ISLAND CHAIN), ATTENTION TURNS TO
HURRICANE KARINA THROUGH EARLY NEXT WEEK. PLEASE REFER TO THE
NATIONAL HURRICANE CENTER FOR MORE INFORMATION REGARDING THE
FORECAST TRACK AND INTENSITY OF LOWELL AND KARINA.
