Swell Summary
A large northwest swell will continue to produce dangerously high surf today, but gradually diminishing wave heights and period will lead to a much reduced threat for significant shoreline impacts. A High Surf Advisory is in effect for exposed north and west facing shores through early Sunday.
A powerful low will pass very close to the islands early next week, thereby producing a long-lived and very large northwest swell that will impact the islands from Sunday night through Tuesday. A High Surf Warning is likely for most north and west facing shores, with a High Surf Advisory also likely for those north and west facing shores less exposed to the swell. Another large northwest swell is possible around the middle of next week. Small surf will prevail along S and E facing shores.
