Strong winds continue to whip across parts of Oahu, Kauai and Maui today.

Meanwhile, warning-level surf is still building along north- and west-facing shores and was expected to peak this afternoon.

A wind advisory was in effect for the windward sides of Oahu and Kauai and Maui’s central valley until 6 p.m. today, the Weather Service said.

Southwest winds were forecast to be 25 to 30 mph today with higher gusts, the advisory said. An advisory means sustained winds of at least 30 mph or gusts of at least 50 mph are expected. Motorists should use extra caution, the Weather Service said.

A high surf warning remains in effect until 6 p.m. Wednesday for north- and west-facing shores of the islands from Niihau to Molokai, and along with north-facing shores of Maui.

The northwest swell will build across the state tonight and peak today, bringing dangerously high surf to most north- and west-facing shores of the smaller islands, the Weather Service said.

Surf was forecast to hit 25 to 35 feet for north-facing shores and 18 to 23 feet for west-facing shores.

Ocean water will occasionally sweep across portions of beaches, and beachgoers can expect strong breaking waves and rip currents, the Weather Service said.

Anyone entering the water could face significant injury or death, and boaters should be aware of more surfers or body boarders in the water, the Weather Service said.
