A whiteout is the term that refers to a severe storm condition with blowing snow, wind drifts, and high winds with reduced visibility.

  • When the sky is overcast and the ground is snow-covered, the landscape may appear entirely white, with no visible horizon.
  • Distances are difficult to judge. Variations in terrain are not easy to recognize.

Do not ride in a whiteout if you can avoid it, but if you must:

  • Be extremely cautious, and maintain a low speed.
  • Stay in familiar areas only, and watch for indications of hazards such as drop-offs beneath the snow.
