A high surf advisory is in effect for the south shores of all islands until 6 a.m. Sunday, the National Weather Service said.

Surf was forecast to reach 5 to 8 feet and remain elevated tonight due to a long-period swell, the weather service said.

Higher than normal tides were also expected through the holiday weekend, possibly causing some run up and beach flooding when combined with the high surf.

Forecasters said the surf will slowly trend down over the next few days.

Vog will likely begin blowing over the smaller islands on Sunday, the Weather Service said.

A cold front to the northwest of the state is causing the shift in winds. Forecasters said this change in winds will also bring moisture and muggy conditions through the middle of the week.
