today and peaking at 20 to 25 feet late tonight and Tuesday.
Along east facing shores, surf building to 7 to 10 feet this

* WHERE...North and east facing shores of Niihau, Kauai, Oahu,
Molokai, Maui, and Big Island.
* WHEN...From noon today to 6 PM HST Tuesday.
* IMPACTS...Very High...Expect ocean water surging and sweeping
across beaches, creating the potential for impacts to coastal
roads and infrastructure, mainly along windward coasts.
Powerful longshore and rip currents will be present at most
beaches. Large breaking waves and strong currents may impact
harbor entrances and channels causing challenging boat
handling, mainly in Hilo and Kahului.
Stay away from the shoreline along the affected coasts. Be
prepared for road closures. Postpone entering or leaving channels
affected by the high surf until the surf subsides.
