306 AM EDT FRI AUG 7 2026
VALID 00Z SAT 08 AUG 2026 - 00Z SAT 15 AUG 2026
THE TRADE WINDS STRENGTHEN AS AN UPPER LEVEL TROUGH RETROGRADES
AWAY FROM THE NORTHWESTERN MAIN ISLANDS THROUGH THE
PAPAHANAUMOKUAKEA MARINE NATIONAL MONUMENT. THE STRONGER TRADES
ARE EXPECTED TO CONTINUE THROUGH THE WEEKEND AND INTO LATE NEXT
WEEK. A DISTURBANCE IN THE TROPICAL EASTERLIES TO THE SOUTH OF
THE SUBTROPICAL RIDGE INCREASES MOISTURE THIS WEEKEND WHICH
SHOULD INCREASE HEAVY RAIN POTENTIAL PRIMARILY ON THE ISLAND OF
HAWAI'I. OTHERWISE, MAUKA SHOWERS ARE EXPECTED DURING THE NEXT
WEEK.
