Strong winds and waves are buffeting the islands as a high surf warning goes into effect.

The National Weather Service posted a high surf warning for the east shores of all islands except Lanai and Niihau this morning. Surf along affected shores is expected to reach 10 to 15 feet through tonight, easing to 8 to 12 feet Thursday.

The high surf warning is in effect through 6 a.m. Friday.

“Large breaking surf, significant shorebreak, and dangerous currents make entering the water very hazardous. Anyone entering the water could face significant injury or death,” weather officials said in a bulletin.

Strong winds are whipping through windward areas of Molokai, Maui and Hawaii island, resulting in a wind advisory until 6 p.m. today.

Weather officials caution the public of easterly winds of 20 to 35 miles per hour, with localized gusts over 50 miles per hour in interior areas of Hawaii island through the Humuula Saddle, with the strongest over the western end. Winds are also expected on the windward side of Hawaii island from Laupahoehoe northwards around Upolu Point, and over the Kohala mountains, and around South Point in the Kau district. Winds are also expected over Molokai, Maui and Kahoolawe.

Residents are advised to use extra caution when driving, secure loose belongings on properties and be prepared for power outages.

A high surf advisory also remains in effect for the east shores of Kauai, Oahu, Molokai, Maui and Hawaii island through Friday morning.

Strong onshore winds combined with large seas will continue to generate rough surf along east-facing shores. Surf will gradually trend down through the upcoming weekend.

Beachgoers, swimmers and surfers should heed all advice given by ocean safety officials and exercise caution. If in doubt, do not go out.

Forecasters say gusty trades associated with a strong high-pressure system will hold through the upcoming weekend. Mostly cloudy skies are expected for the rest of the week, with scattered showers windward and mauka.
