Update 6:30 a.m.
An earlier winter storm warning has been canceled, but a winter weather and wind advisories is in effect for the higher summits of Hawaii island this morning.
The potential for freezing drizzle and fog prompted forecasters at the National Weather Service to issue the winter weather advisory early this morning for Big Isle summits over 12,000 feet.
Winds of 25 to 45 mph with gusts up to 70 mph on summits above 8,000 feet prompted the wind advisory, which is in effect through 6 p.m.
Temperatures are expected to hover between the upper 20s to lower 30s, rising to the mid-30s around noon.
Weather officials warn of hazardous driving with up to a quarter-inch of ice on affected roads and visibility of less than a quarter-mile at times.
The slopes of Hawaii island were under a winter storm warning today as several inches of snow were expected to fall this evening.
The warning is in effect until 6 a.m. Sunday for Big Island summits above 12,000 feet and above 8,000 feet on Mauna Loa and Mauna Kea, the National Weather Service said.
An upper-level disturbance was bringing moderate to heavy snow as it moved over the eastern part of the state.
Cameras on Mauna Kea showed snow covering the ground and poor visibility this afternoon.
Heavy, blowing and drifting snow and gusts of up to 45 mph were forecast for the area. Visibility was expected to be poor — at times falling below a quarter-mile.
Two to four inches of new snow was expected to fall this evening, with light snow possible after midnight, the Weather Service said.
Travel may be hazardous or impossible in the area, and summit visits should be postponed until conditions improve, the Weather Service said. Driving or hiking in the area can be very dangerous, and anyone camping in the area should consider moving to lower elevation.
