Winter storm watch issued above 12K feet for Big Island summits of Mauna Kea, Mauna Loa

National Weather Service forecasters has issued a winter storm watch that will be in effect from 6 p.m. Thursday (March 12) to 6 p.m. Saturday (March 14) for above the Big Island summits of Mauna Kea and Mauna Loa above 12,000 feet.

A powerful Kona low storm located northwest of the state will bring periods of heavy snow, thunderstorms and strong winds Thursday night through Saturday to the island and summits.

Heavy snow is forecast atop both mountains, with total snow accumulations up to 8 inches possible.

A winter storm watch means there is potential for significant snow or ice accumulations that can impact the summits.

Anyone planning travel to the summits, including hikers and campers, should monitor the latest weather forecasts and consider postponing their trip until weather conditions improve.

Travel could be very difficult to impossible. Blowing snow will significantly reduce visibility at times, including periods of zero visibility.
