Mostly dry and breezy northeast trade wind conditions will prevail across the island chain over the next 24 h. As a result, AIRMET Tango continues for low-level turbulence across leeward areas of all islands. Brief periods with MVFR CIGS/VSBYS are possible in passing showers, mostly through the early morning hours today.

A low pressure system north-northeast of the islands and a high pressure system to the north-northwest of the Hawaii region will keep northeasterly trade winds in the forecast through the week.A Small Craft Advisory (SCA) has decreased in coverage to most eastern coastal waters through early Thursday morning for winds. Winds will briefly ease on Thursday and Friday, likely falling below SCA thresholds. A new high pressure develops far northwest of Hawaii by Friday night, strengthening trade winds into the fresh to strong range this weekend with returning SCA conditions from Saturday into the first half of next week.
A short to medium period north-northeast swell will slowly decline today. The forerunners of another small northwest swell will arrive at the buoys later today, with the medium period swell peaking around 3 feet on Thursday, before gradually declining through the weekend. For east facing shores, short period wind wave energy from northeasterly trade winds will hold into the weekend. Strengthening northeasterly winds this weekend and potential gales associated with a low around one thousand miles northeast of the islands will lead to the potential for high surf advisories along north and east facing shores from Sunday into early next week.
For south facing shores, small background energy pulses will keep surf heights just above flat conditions into early next week.
Small Craft Advisory until 6 AM HST Thursday for Alenuihaha Channel-Big Island Leeward Waters-Big Island Southeast Waters- Big Island Windward Waters-Maalaea Bay-Maui County Leeward Waters-Pailolo Channel.
