Strong and gusty winds are expected to move over the western waters of the Hawaiian islands today, according to forecasters, with the winds carrying low clouds and rain showers over the smaller islands.

Forecasters said rainfall will be heaviest over the windward areas and the winds are strong enough to possibly spread the showers leeward to the smaller islands.

Today will be mostly sunny with scattered showers in Honolulu and north winds around 11 mph, according to the National Weather Service.

Scattered showers are forecasted today in Hilo with a chance of 50 percent precipitation, while isolated showers are forecasted in Kailua-Kona with a chance of 20 percent precipitation.

Showers are likely on Kauai with a chance of 60 percent precipitation. On Maui, scattered showers are forecasted with a chance of 50 percent precipitation.

Showers will move from the northeast of the Hawaiian islands to the leeward and interior areas Sunday due to afternoon sea breezes. Although rain will likely increase early next week, thunderstorms and heavy rain will be possible, especially for Hawaii island, through the middle of the week, forecasters said.

The National Weather Service in Honolulu has also issued a high-surf advisory for the north-facing shores and a high-surf warning for the east-facing shores through this evening. The high-surf advisory may likely be extended tonight through Sunday for the east-facing shores, forecasters said.

A high-surf warning is in effect for the east-facing shores of Oahu, Hawaii island, Kauai, Maui and Molokai until 6 a.m. Sunday. A high-surf advisory is in effect for the north-facing shores of Oahu, Hawaii island, Kauai, Maui, Molokai and Niihau until 6 a.m. Sunday.

Surf of 10 to 16 feet is expected along the north- and east-facing shores of Oahu, Hawaii island, Kauai, Maui, Molokai and Niihau.

Beachgoers, swimmers and surfers should exercise caution and heed all advice given by Ocean Safety officials. Expect strong breaking waves, longshore and rip currents. Ocean water may occasionally sweep across portions of Hawaiian isle beaches, forecasters warned.

“Anyone entering the water could face significant injury or death,” the warning said. “Boaters should be aware of an increased number of surfers and body boarders utilizing the harbor channel to access surfing areas.”

As a result of the freezing drizzle, snow and ice-covered roads on the summits, the National Weather Service advises visitors to postpone travel plans to the summits until conditions improve. The National Park Service closed the road leading to the Haleakala summit as well as the road leading to the summit of Mauna Kea.
