(BIVN) – Very strong flow associated with an upper level trough will produce warning level winds over the Big Island summits through tonight, as the National Weather Service in Honolulu issued a High Wind Warning.

Southwest winds will blow at 35 to 65 mph with localized gusts over 70 mph, forecasters say. Travel to the summits is not recommended until winds have subsided.

The road to the summit of Mauna Kea is closed to the public at the Visitors Information Station at an elevation “due to high winds, high humidity, fog and wet road conditions,” rangers say.

The summit of Mauna Loa is also closed to backcountry hiking due to the high wind conditions.
