High surf warning issued for portions of Kaua‘i, Ni‘ihau; wind advisory also in effect
The National Weather Service in Honolulu has issued a high surf warning for north-facing shores of Kaua‘i and Ni‘ihau through 6 p.m. Friday.
Dangerous surf of 20 to 25 feet is forecast along north-facing shores. A very large north swell will build tonight into Thanksgiving Day, producing surf that will reach warning-level heights along those shores. The swell coincides with strong gale-force northeast winds, as well as high tide during the early morning hours Thursday and Friday. Significant overwash issues and large wave runups along north-facing shorelines could occur.
Entering the water in these areas during the warning is hazardous and could cause serious injury or death. Beachgoers are advised to use extreme caution as large breaking waves could make it dangerous for those standing along the shoreline.
The warning could be extended or modified as conditions develop.
A high surf advisory is also in effect until 6 p.m. Friday for west-facing shores of both islands. Large breaking waves of 12 to 16 feet is forecast along these shores. Strong breaking waves and strong currents will make swimming dangerous in these areas.
A wind advisory is also in effect for both islands until 6 a.m. Friday. Northeast winds 25 to 35 mph, with gusts up to 55 mph, are expected.
Winds this strong can tear off shingles, knock down tree branches, blow away tents and awnings and make it difficult to drive, especially for drivers in high profile vehicles. People are advised to watch out for falling tree branches when walking or driving, make sure tents and awnings are secure or take them down and be prepared for power outages.
