30-foot waves expected
at north and west shores
A high-surf warning remains in effect for all of Oahu's north- and west-facing shores today as waves of up to 30 feet were expected to hit early this morning.
National Weather Service officials said 20- to 30-foot surf was to hit Oahu about midnight yesterday and continue to rise today.
Forecasters said the hurricane-force winds of a storm located west-northwest of Hawaii generated the high surf.
While surf along north-facing shores was expected to increase to heights of 20 to 30 feet, surf along west-facing shores was expected to increase to heights of 12 to 20 feet for the same period.
Forecasters said another west-northwest swell is expected to arrive late tomorrow, and by Thursday could peak with surf heights above the high-surf warning level of 25 feet.
This swell is expected to diminish slowly Friday and Saturday.
Another west-northwest swell is expected Sunday with surf heights of 15 feet.
