Marine Weather Message in Effect for the Coastal Waters
From the Marine section from the Area Forecast Discussion
issued at: Nov 24, 2009 4:00 PM HST
A large northwest swell will arrive late tonight. A high surf warning has been issued for north and west facing shores of Niihau Kauai Oahu and Molokai, and for north facing shores of Maui. Based on the expected swell direction of 320 degrees, we do not expect that surf will reach advisory thresholds for north or west facing shores of the Big Island due to shadowing by the smaller islands. The swell will peak Wednesday then slowly decrease, but surf heights will likely remain near or above advisory thresholds through Friday.
A small craft advisory is in effect for both the large northwest swell and for increasing trade winds starting tonight.

The marine forecasts issued are based on marine observations and model data. Marine observations include buoy and ship reports. Ship reports are invaluable to the NWS, and are reported through the U.S. Voluntary Observing Ship Project. If you are a mariner, please consider joining the nearly 1,000 volunteer ships from around the world that observe the weather at their location.
