Small craft advisory remains in effect for Big Island

A small craft advisory remains in effect for waters off Hawaii Island effective through 6 p.m.

National Weather Service forecasters in Honolulu said the advisory was prompted by a large north swell producing rough seas. The service forecast northeast winds reaching 15 knots or 17 mph. Rough seas of 7 to 15 feet are also expected.

The service also warned of large breaking waves and strong harbor surges at Hilo Harbor.

A small craft advisory means that wind speeds of 25 to 33 knots — 29 to 38 mph — and/or seas are expected to be 10 feet or greater and expected to produce conditions hazardous to small craft, according to the service. Inexperienced mariners, especially those operating smaller vessels, should avoid navigating in such conditions.
