First Alert Forecast: Threat of thunderstorms, wind continues as front sweeps through islands

A strong cold front will continue through the islands into the evening, with a threat for severe thunderstorms and damaging winds, especially for Maui County and the island of Hawaii.

Weather conditions are forecast to improve for Kauai and Oahu into the evening, but strong west winds will remain a concern and bring some lingering shower bands over leeward areas into Tuesday.

By Wednesday, lighter winds and drier conditions are expected. Trade winds will remain absent for the rest of the week as a cold front passes to the north late in the week. This front is forecast to remain well to the north of the state.

In surf, extra-large and rough waves generated by the storm system are forecast to peak overnight into Tuesday morning near 30 to 40 feet for north shores and 20 to 30 feet for west shores. A high surf warning will remain posted for those shores through 6 p.m. Tuesday.

Here’s a list of weather alerts:
