Swell Summary
A powerful low northwest of the islands will produce a long-lived and extra-large northwest swell that will bring surf heights well above High Surf Warning levels. There is high potential for wave run-up onto vulnerable roadways and coastal areas in the Warning areas, with the most likely time for these impacts being Monday night into Tuesday morning during high tide. This swell is expected to drop below warning thresholds Tuesday night into Wednesday, but a large northwest swell is possible during the second half of the week. Surf along south and west facing shores will also see an increase in short-period wind waves this evening into Tuesday due to the strong onshore winds.
