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 AND WEST FACING SHORES OF THE BIG ISLAND STARTING NOON TODAY...

.A giant northwest swell will build today, peaking on Kauai during the late morning, on Oahu shortly after midday, and mid- to late- afternoon on Maui. Some of the swell`s energy is expected to reach portions of the Big Island later in the day, peaking tonight. A gradual decrease in wave heights is expected on Sunday, but another large swell is expected to arrive by Monday.

...HIGH SURF WARNING REMAINS IN EFFECT UNTIL 6 AM HST SUNDAY...

* WHAT...Surf 40 to 50 feet along north facing shores, and 25 to 35 feet along west facing shores.

* WHERE...North and west facing shores of Niihau, Kauai, Oahu and Molokai, and north facing shores of Maui.

* WHEN...Until 6 AM HST Sunday.

* 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.

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.
