Forecast: Winds will gradually decrease, but remain strong through mid-week

Winds should ease a bit on Oahu and Kauai, but Maui and Hawaii island continue to see advisory-level wind gusts.

The National Weather Service has extended its high surf advisory for the east shores of Oahu, Kauai, Molokai, Maui and Hawaii until 6 p.m. Monday. 

Surf along those eastern shores is expected to reach seven to 10 feet, and strong tradewinds will continue to make ocean conditions very rough, the service reported. 

A wind advisory for Molokai, Lanai, Kahoolawe, Maui, and parts of Hawaii Island will remain in effect until 6 p.m. today. 

And small craft advisories until 6 a.m. Monday have been issued for the northwest, windward and leeward waters of Kauai, the Kauai Channel, windward and leeward waters of Oahu, the Kaiwi Channel, Maui County windward and leeward, Maalaea Bay, and Hawaii island windward waters.

The National Weather Service says a high pressure system northeast of the state continues to generate strong tradewinds over all islands.

The strongest winds are in Maui county and Hawaii island, which should see winds of 25 to 45 mph through this evening. The highest gusts are in the mountain areas of Haleakala and Hawaii island. The advisory-level winds are expected to continue through tonight.

The winds could bring down tree branches and make driving hazardous.

Oahu and Kauai are also seeing strong trade winds in the 20 to 30 mph range.

The weather service says the winds could blow in some showers to all islands and there is the possibility of thunderstorms on Hawaii island.

Forecasters expect the winds to gradually decline as the high pressure system moves away, but expect a windy start to the work week.
