Swell Summary
A small, medium period northwest (310-330 degrees) swell will continue to slowly lower through tomorrow morning. A new moderate, long period northwest swell (330 degree) will then fill in and peak just below advisory levels tomorrow night into Saturday. A potentially extra large, long period northwest swell (330 degree) originating from a hurricane force low is expected to reach the islands Sunday and peak Sunday night into Monday. This swell could produce warning level surf along exposed north and west- facing shores during the peak. In addition sea levels will likely rise above SCA criteria.
Expect east shore surf to remain elevated and choppy through tomorrow and ease slightly over the weekend as winds decrease. Small south shore surf sets will persist through the forecast period as several very small, long period south swells move through.
