Molokai, and north facing shores of Maui.

* WHEN...Until noon HST Monday.

* IMPACTS...Very High...Expect ocean water surging and sweeping
across beaches, coastal benches, and lava flows creating the
potential for impacts to coastal properties and infrastructure,
including roadways. 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.

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.
