Volcanic haze over Oahu and other western islands will continue with varying degrees of haziness as surf rises to giant levels Monday night.

The National Weather Service expects to issue a high surf warning Monday night as two new swells bring extra-large surf to north and west shores of most islands. The surf should remain at warning levels Tuesday and a new swell should keep huge surf coming in through Wednesday.

The current swell remains at advisory levels through 6 a.m. Monday for north and west shores of Kauai County and north shores of Oahu, Molokai and Maui.

Forecasters are expecting a series of weak fronts to pass over or near the islands over the next week, creating variable winds and periods of vog.

The fronts could bring a few more showers to the islands, but is not expected to bring heavy rain.

The forecast for Honolulu and south shores of Oahu calls for cool nights, light winds and hazy conditions.
