...High Surf Warnings and Advisories are in Effect for the Hawaiian Islands...

A strong area of high pressure to the northeast of the Hawaiian Islands is bringing windy conditions and high surf to the islands. Waves reaching up to 35 feet in height are possible in some areas. Wave activity will peak overnight tonight, and then subside over the next couple of days. The public is being urged to stay away from the shoreline until the dangerous conditions have ended.
