Aloha,

The road to the summit of Maunakea remains closed to the public at the Visitor Information Station at an elevation of 9,200 feet due to a high wind warning issued by the National Weather Service that extends until Monday, February 8th, 2016 at 6:00 a.m. Sustained winds have been over 60+ mph continually with 90+ mph gusts at the Summit. This message will be updated as conditions change. Thank you for your patience and understanding.

Mahalo and have a nice day!
Maunakea Rangers



More Information: Mauna Kea weather varies widely. A calm sunny day may quickly become treacherous with hurricane force winds and blizzard conditions. Summit winds above 120 mph are not uncommon. Snowstorms have even occurred during the summer months.

When conditions are too dangerous, the Summit Access road is closed at the Visitor Information Station to ensure everyone's safety. The road is re-opened as soon as the weather and the roads are safe again.

Traffic delays and road closures on the summit access road may also occur due to the use and transport of heavy equipment, slow vehicle movements, deliveries, road maintenance, stalled or abandoned vehicles, hikers and bikers. Remember that dust, fog or snow can reduce visibility and slow traffic. Specific road closure criteria is listed below:

1. Any ice or snow on the road.
2. Winds greater than 55 mph for one hour and/or gusts greater than 65 mph.
3. Visibility less than 50 feet.
4. Any emergent condition that makes the road unsafe for travel.

Mahalo for your understanding.
