Hurricane Lala will move over or just south of Big Island today and continue to the west northwest or west through the remainder of the weekend. High winds, potentially flooding rains, and high surf impacts will be felt statewide. A Hurricane Warning is in effect for Big Island and a Tropical Storm Warning is in effect for the rest of the state. Trade wind weather will return Monday.
The center of Hurricane Lala is approximately 80 nm SSE of Hilo this morning and is moving west northwest at around 11 knots. Lala is forecast to pass in the vicinity of South Point, Big Island this afternoon. Island-wide TAF sites will experience strong northeast winds gusting to tropical storm force peaking through 02-12Z southern Islands and 10Z-17Z northwestern islands. For PHKO low confidence in wind shift timing. IFR to MVFR cigs/vsbys will be common in heavier showers and nearest Lala.
A Big Island and Maui AIRMET for surface winds greater than 30 knots and IFR conditions is currently in effect.
AIRMET SIERRA is currently in effect for north through east areas of Big Island, Maui, Lanai and Molokai for mountain obscuration above 2500 feet.
AIRMET TANGO for moderate turbulence remains in effect immediately south and west of mountains due to low level winds. TANGO likely continue the next couple of days.
Ne winds ramp up as Hurricane Lala approaches the Big Island. The strongest winds are expected this evening into tonight for the waters of Big Island and Maui County and on Sunday for Kauai and Oahu. Hurricane and Tropical Storm Warnings remain in effect. Trades return from Tuesday onward.
Surf is rapidly building along SE facing shores of the Big Island where very large surf is anticipated in the front right quadrant of the hurricane. Surf is also building along E facing shores for which High Surf Warnings are in effect except for Kauai where advisory level surf is expected. Surf rapidly declines tonight for the eastern end of the state but will take through Sunday to fall below the advisory threshold for the smaller islands.
Choppy conditions for N shores as short period swell wraps from the east through the weekend. For S shores, surf remains below the advisory threshold but will receive a small boost as short period swell associated with Lala works through the area. Long period energy from a distant Southern Ocean swell maintains S shore surf Sunday into Monday.
