A strong high far north of the state will produce windy and rough conditions across all area waters through at least the middle of next week. The current strong trade winds will strengthen another notch on Sunday with widespread strong to near gales expected across the coastal and offshore waters. The windier channels around Maui County should see wind speeds increasing during the day tomorrow to gale force speeds. A Gale Warning has been issued for Sunday and Sunday night for the Alenuihaha and Pailolo channels. Elsewhere, a Small Craft Advisory (SCA) remains in effect due to a combination of winds and seas. Winds may ease slightly by Monday, but overall strong to near gales will continue across the state through the middle of next week.

Nearshore buoys such as the Mokapu buoy has been showing a steady rise over the past 12 hours. Surf along east facing shores have now reached advisory thresholds and will continue to build through Sunday night as the trade winds strengthen another notch. High Surf Advisory is now in effect for east facing exposures of Kauai, Oahu, Molokai, Maui and the Big Island through Monday night. This advisory could very well get extended through the middle of next week due to the strong trade winds persisting across the state.

The current small medium period northwest to north-northwest swell will steadily decline this evening through Sunday. Minimal energy is expected from the northwest during the first half of next week, although select exposures should see some wind swell. A small northwest bump is possible towards the second half of next week. Surf along south shores will remain small but a slight increase is expected for areas exposed to the trade wind swell.
