The National Weather Service warns that strong northeast winds of 20 to 30 mph, with gusts over 50 mph, are expected for portions of Kahoolawe, Lanai, Maui and Hawaii island due to a strong high pressure system north of the state.

While rough and choppy surf will bring advisory level surf to eastern shores, surf on all other shores will remain well below advisory levels, forecasters said.

Surf is expected to remain at 0 to 2 feet for southern and western shores,, and at 2 to 4 feet for northern shores, today through Friday.
