Tropical Storm Lala will move over or just south of the islands this weekend but wind, rain and 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.
Tropical Storm Lala will approach Big Island from the southeast through tomorrow morning, passing just south of the island tomorrow afternoon. Northeast winds will remain strong, reaching tropical storm force in gust at the Big Island, Maui and Molokai TAF sites during this period. Sky and visibilities will deteriorate from east to west across the island chain, as well, with many sites falling to MVFR decks overnight. Heavy rain limiting visibilities to as low as IFR categories are also anticipated for Big Island and Maui County tonight and early Saturday morning, for Oahu and Kauai sites Saturday and afternoon and evening.
AIRMET SIERRA is currently in effect for north through east sections of Molokai, Lanai, Maui, and Big Island above 2500 feet due to low clouds and scattered showers.
AIRMET TANGO for moderate turbulence remains in effect immediately south and west of mountains due to low-level winds and will likely continue for the next couple of days. As wind speeds strengthen, an AIRMET for strong winds greater than 30 knots will likely be needed.
Issued at 514 PM HST Fri Aug 14 2026 NE winds will strengthen areawide through Saturday as Tropical Storm Lala passes over or immediately south of the Big Island. The strongest winds are anticipated Saturday evening into Saturday night for the waters surrounding the Big Island and Maui. Winds peak for the waters surrounding Kauai and Oahu during Sunday. Hurricane Warnings, Tropical Storm Warnings, and Tropical Storm Watches are in effect. Expect dangerous conditions including torrential rainfall, a few thunderstorms, and high surf. Lala will track WNW through the weekend, clearing the western islands by Monday. Tuesday into the rest of the week, a return to easterly trades is expected.
Surf initially trends slowly upward for E shores in response to strengthening trades, but will quickly build tonight as Lala approaches. The High Surf Warning remains in effect for E facing shores of the Big Island and Maui as well as the SE facing coasts of the Puna and Ka'u Districts where surf will be maximized. Surf is also forecast to reach low end warning critiera for E facing shores of Oahu and the advisory threshold for Kauai. Accordingly, the High Surf Warning has been expanded to include Oahu and a High Surf Advisory has been issued for E facing shores of Kauai.
For N shores, anticipate choppy conditions with swell energy wrapping from the east through the weekend. For S shores, surf will remain below the advisory threshold and will slowly diminish until another long period south swell arrives late Sunday into Monday providing a small boost to existing surf.
