New winter weather advisory issued for Big Island summits atop Mauna Kea, Mauna Loa

Forecasters at the National Weather Service Honolulu office issued another winter weather advisory for the summits of Mauna Kea and Mauna Loa on the Big Island after a previous advisory was canceled early this morning (Jan. 24).

The new winter weather advisory will be in effect from noon today through 6 a.m. Sunday (Jan. 25). The previous advisory was set to be in effect until 6 a.m. today; however, forecasters canceled it just before 3 a.m., as the threat of impactful winter weather ended.

Snow showers will again fall over the summits this afternoon and through the evening as another short-wave trough passes over the island. Snow showers should decrease overnight, but slick road conditions likely will continue through the morning hours Sunday.

Snow of up to 1 to 2 inches and freezing fog are expected in the advisory areas.

Travel could be very difficult at the summits because of the winter weather.

Freezing fog will significantly reduce visibility at times, including periods of dropping to zero.

Slick road conditions are expected.

A winter weather advisory means periods of snow, sleet or freezing rain will cause travel difficulties.

The public is advised to be prepared for slippery roads and limited visibilities; use caution while driving — if you must — in the advisory locations.
