The Honolulu Star Bulletin reports that storms with subzero temperatures and 80 mph winds dumped 6 to 12 inches of snow on the Mauna Kea and Mauna Loa summits prompting closing of the road. The storms also resulted in 30 foot waves on Oahu’s north coast and pushed a foot of sand onto the road leading into Kaena Point State Park
The American Observatory webpage has links to some dramatic webcams of the snow.
