...HIGH SURF WARNING FOR NORTH FACING SHORES OF NIIHAU KAUAI OAHU MOLOKAI AND MAUI... .A very large north, mid-period swell will build tonight into Thanksgiving Day. This swell will produce surf reaching warning level heights along north facing shores of Niihau, Kauai, Oahu, Molokai and Maui through Thursday night. The swell coincides with strong to gale force northeast winds, as well as the spring high tide during the early morning hours on both Thursday and Friday. There could be significant overwash issues and large wave run up along north facing shorelines as a result.

* WHAT...Dangerously large breaking waves of 20 to 25 feet along
north facing shores of Niihau, Kauai, Oahu, Molokai and Maui.

Maui. Areas exposed to north swells on other shorelines should
see a significant rise in surf.

* IMPACTS...High. Expect very strong breaking waves and powerful
currents. Waves breaking in channel entrances may make
navigating the channels dangerous. Significant overwash and
large wave run up may bring coastal flooding and damage.


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.
