A high surf advisory for the east facing shores of Kauai, Oahu, Molokai, Maui and the Big Island is in effect until 6 a.m. Tuesday.

A large, short-period east swell combined with strengthening easterly winds over windward coastal waters will maintain elevated rough surf along east facing shores this week, according to weather officials.

Surf along east facing shores is expected to reach six to 10 feet through this afternoon, and increase to eight to 12 feet tonight. Expect strong breaking waves, shore break, and strong longshore and rip currents making swimming difficult and dangerous.

In the forecast, showers are expected to decrease gradually across the state today and tonight as the upper trough west of the area weakens and a ridge aloft builds in from the northeast. East winds will increase through midweek, with very windy conditions expected in some areas.
