Hawaii County Civil Defense said in an alert message (click above to hear) that the warning will be in effect until at least 6 p.m. Saturday.

The National Weather Service says the large northwest swell will keep hazardous surf through Saturday. “The swell has more of a westerly component than normal,” meteorologists say, “so west facing shores of the Big Island will see much larger than normal surf.”

From the high surf warning posted to the National Weather Service website:

National Weather ServiceNational Weather Service, Dec. 20, 2013

“* Surf… 20 to 30 feet for north and west facing shores of Niihau and Kauai and north facing shores of Oahu, Molokai and Maui with locally higher sets. The larger sets will be more frequent on north and west facing shores of Kauai and Niihau.

* timing… Surf will build rapidly across the area today.

* impacts… High… Expect ocean water occasionally sweeping across portions of beaches… Very strong breaking waves and strong longshore and rip currents. Breaking waves may make navigating some harbor channels dangerous.
