High Surf Warning
Effective: Saturday, January 13, 2018 - 3:27pm to Monday, January 15, 2018 - 6:00am
.An extremely large, long-period northwest swell will peak overnight and early Sunday, producing surf well above the warning levels along most north and west facing shores. Surf will likely decline below warning levels on Monday but remain elevated above advisory levels into Tuesday.
...HIGH SURF WARNING NOW IN EFFECT UNTIL 6 AM HST MONDAY...
* SURF...Building to 20 to 30 feet for exposed north facing shores of the Big Island, mainly in the Puna District.
* TIMING...Surf will rapidly build this evening, then hold at warning levels through Sunday night.
* 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.
A High Surf Warning is issued when waves reach threshold criteria for a particular island and shoreline. High Surf Warnings may be issued up to 24 hours ahead of the arrival of the swell and may remain in effect for several days.
Unmonitored lands and waters in the impact area described in the alert will also be impacted.
If conditions change before expiration or the event needs to be extended, an update or cancellation will be issued from Hawaii Beach Safety Website.
