  1. Contrast vanishes, so you cannot tell the horizon or snow surface ✔
  2. The sky turns black while the snow glows
  3. Everything looks closer and sharper than it really is

Why: A whiteout happens when light bounces between snow and an overcast sky. Shadows disappear, so slopes, bumps and the horizon blend together. Slow down and stay near people you know.

Huh, didn't know that: A whiteout needs a snow surface plus an overcast sky, because the light keeps bouncing between the two.

The dad joke
What happens when the snowman cannot see properly? The snowman rubs his ice!
