The National Weather Service has issued a high-surf warning for north- and west-facing shores of Niihau, Kauai, Oahu, Molokai, Lanai and Maui and west-facing shores of the Big Island.

The warning remains in effect until 6 p.m. Thursday.
The weather service says a large northwest swell is entering Hawaiian waters today and will gradually make its way down the chain.
Surf along north-facing shores is expected to be 25 to 35 feet today, the weather service says. Waves on west-facing shores will be in the 15- to 20-foot range.
The swell also has prompted the weather service to issue a small-craft advisory for most state waters.
Meanwhile, it will be another hazy day as southwest winds continue to carry vog across the state.
The haze is expected to linger through tomorrow before trade winds return Thursday and Friday.
