*** START NOTIFICATION ***

Effective: Tuesday, December 18, 2018 - 3:55pm to Wednesday, December 19, 2018 - 6:00pm

Alert:
...HIGH SURF WARNING FOR NORTH AND WEST FACING SHORES OF NIIHAU KAUAI OAHU MOLOKAI AND NORTH FACING SHORES OF MAUI...

...HIGH SURF ADVISORY FOR NORTH FACING SHORES OF THE BIG ISLAND...

.A large north-northwest (340 degree) swell will peak this evening and tonight and gradually decrease Wednesday afternoon. The combination of strong north to northeast winds, large surf, and above normal high tide levels, will increase the risk for significant beach erosion and possibly lead to some minor overwash onto coastal roadways.

...HIGH SURF WARNING REMAINS IN EFFECT UNTIL 6 PM HST WEDNESDAY...

* SURF...24 to 30 feet through Wednesday morning along north and west facing shores of Niihau and Kauai, and north facing shores of Oahu, Molokai and Maui. Decreasing to 20 to 26 feet Wednesday afternoon. 18 to 24 feet through Wednesday morning along west facing shores of Oahu and Molokai. Decreasing to 15 to 20 feet Wednesday afternoon.

* TIMING...Through 6 PM Wednesday.

* 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.
Notes (optional):

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.

Warning Instruction:
Large breaking surf, significant shorebreak, and dangerous currents make entering the water very hazardous. Anyone entering the water could face significant injury or death. Boaters should be aware of an increased number of surfers and body boarders utilizing the harbor channel to access surfing areas.

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.
