Wind advisory Monday

High winds forecast for the islands have prompted the National Weather Service to continue a wind advisory for most of the state Tuesday.

The strong trade winds are also causing choppy ocean conditions, with a gale warning issued, a high surf advisory for windward shores and a small craft advisory for all Hawaiian waters.

Wind speeds are forecast to remain around the 20-35 mph level Monday, with gusts reaching up to 50 mph. High terrain and downslope areas are likely to see those stronger, gustier winds.

The wind advisory is scheduled to last until 6:00 p.m. Tuesday. A strong high pressure system lingering north of the state will drive the gusty conditions for the entire state through Tuesday. That system is expected to slightly weaken Tuesday night.

Though the system may weaken, the steadily strong breezes will likely continue for most of the week. This will maintain choppy ocean conditions during that time.

The high surf advisory for windward coasts is scheduled to last until at least 6:00 p.m. Thursday. The wind swell is forecast to rise through Monday and expected to continue bringing overhead waves around five to eight feet, face value, for most of the week.

A small craft advisory is similarly issued for all Hawaiian waters, with gale warnings for all coastal waters within 40 miles of the shore. The gale warning is set to expire by sundown Tuesday, though the breezy trades will likely continue past that warning.
