A light layer of snow could be seen at the “MK Visitor Center” cam at Halepohaku, commonly referred to as the Mid-Level area. The spot, located at the 9,300 ft elevation of the 13,800 ft. mountain, is usually without snow even when the summit gets covered.
In a 9:27 a.m. HST message, the National Weather Service in Honolulu maintained the Winter Weather Advisory for the Big Island summits until 6 a.m. Tuesday, saying “additional snow accumulations of up to two inches, and ice accumulations of around one-tenth of an inch” are possible. Forecasters said:
Although temperatures may rise above freezing today on the Haleakala Summit, sub-freezing temperatures are expected again tonight, increasing the potential for freezing rain and black ice. Temperatures on the Big Island Summits are expected to remain below freezing through at least tonight, with bouts of wintry weather.
A High Wind Warning is also in effect, and the Mauna Kea Acess Road is closed at Halepohaku. Mauna Loa Summit is also temporarily closed due to the winter weather hazard.
