South swell in the islands continues – Hawaii

Moderate to locally fresh trade winds will continue to weaken as a stronger surface trough north of Kauai weakens the local pressure gradient. The trough will strengthen Thursday night and Friday and spread across the islands and linger into the weekend, disrupting local winds. A strong disturbance in the air will pose a threat to strong to heavy thunderstorms, especially from Friday to Saturday. These thunderstorms can produce dangerous wind gusts, hail and frequent lightning. Moderate easterly to southeasterly trade winds will gradually build back up Sunday or Monday.

South: A prolonged southerly swell will hit the islands in the coming days. Low, long-lasting precursors of 19 to 21 seconds have begun arriving at the local buoys this afternoon and will build over the area this evening. Surf on the south coast is expected to reach near or possibly reach the High Surf Advisory level of 10 feet from Thursday afternoon through Friday during the peak of the swell. We have postponed issuing advice for the time being, but will keep a close eye on the buoys tonight. This long-lived swell will gradually diminish Saturday through Monday, with a small south-southwest pulse expected to follow early next week.
