Aloha Visitors,

Currently the road to the summit of Maunakea is closed at the Visitor Information Station (VIS), at the 9,000' level, due to snow and ice beginning to build up on the summit roads. It's been raining most of the night, and as temperatures drop leading up to sunrise this morning, we anticipate possible further formation of dangerous black ice on the summit roads. As a precaution, we've closed the road. As conditions change, rangers will update this message. You can also call 808-935-6268 for the latest information on summit road conditions.

Mahalo for your patience,

Maunakea Rangers
