The National Weather Service is warning that wind gusts of 50 mph could hit most of the Hawaiian Islands Monday.

A high wind advisory is in effect for Oahu, Kauai, Molokai, Maui and Lanai, the weather service said.

An approaching front will generate southwest winds of 15 to 30 mph Monday afternoon and possibly into Monday evening in Maui County, forecasters warn.

The summits of Hawaii island, meanwhile, are under a high wind warning until 6 p.m. Wednesday.

Winds of 55 to 65 mph Sunday are expected to increase to 65 to 80 mph Monday, the weather service said.

Forecasters advise delaying travel to the summits of Mauna Loa and Mauna Kea until the winds die down.

There is also a small craft advisory in effect for all Hawaiian waters through 6 p.m. Tuesday because of the winds and rough seas.

Southerly winds will gradually strengthen through early Monday morning, especially on Kauai and Oahu as the “vigorous” front approaches from the northwest, the weather service said. Strong and gusty southwest winds will continue across areas to the north and east of the higher terrain on the smaller islands starting on Monday as the front nears. 

Moisture ahead of the front will bring showers to portions of the Big Island on Monday, while rainfall along the front will be focused on Kauai by Monday afternoon, before the wet weather moves down the rest of the island chain from Monday night through Tuesday.
