A winter weather advisory has been posted for the Big Island’s Mauna Loa and Maunakea summits through noon Monday.
National Weather Service forecasters in Honolulu said Friday a trough aloft will linger near the islands for the next couple of days, bringing sub-freezing temperatures to the Big Island summits. Additionally, the trough will destabilize the island atmosphere, and moisture moving in with the trade winds will occasionally extend above the summits.
“This will lead to periods of freezing rain and snow showers the next couple of nights and days,” forecasters said.
Forecasters cautioned of icy roadways, making for very dangerous driving at the summits, which could prompt road closures. The Maunakea Access Road was closed as of Friday evening.
