Hazards Feed: RSS Feed  Forecast Feed: RSS Feed

Synopsis for Hawaiian coastal waters:
A front located just northwest of Kauai will be approaching the Hawaiian islands today and will begin impacting the Kauai waters early this afternoon. The front will then reach Oahu this evening into tonight and stall and gradually dissipate near Maui on Friday. Locally strong northeast trades will briefly return Saturday as a surface high passes north of the islands. Then another front will enter the far western offshore waters Sunday night. This will cause the winds to veer to the south Sunday and Monday.
