What is a “white-out”?

An official definition for “white-out” does not exist. It is a colloquial term that can describe any condition during snowfall that severely restricts visibility. That may mean a blizzard, or snow squall, etc. If you get some sunlight in the mix, that makes the situation even worse—it’s like driving in fog with your headlights on high-beam. The light gets backscattered right into your eyes and you can’t see.
