  Park Service has closed the road leading to the summit of 
  Haleakala. The road to the summit of Mauna Kea remains closed to
  the public at this time as well. Travel to the summits should

  times, along with icy and snow covered roads. This is a 
  potentially life threatening situation for anyone traveling to 
  the summits and should be avoided until conditions improve.

cause travel difficulties. Be prepared for snow covered roads and
limited visibilities, and use extreme caution while driving.
