Etymology
Origin of whiteout
1940–45; whiteout ( defs. 2, 3, 4 ) noun use of verb phrase white out; whiteout ( def. 1 ) white + (black)out
Explanation
A whiteout happens when snow falls so fast and heavily that you can't see very far in front of you. It's not safe to drive in a whiteout. Whiteout is an official meteorological term, also known as "milky weather." A true whiteout occurs when there's snow on the ground, falling or blowing snow, and a hazy sky that contributes to an observer's inability to see anything but vague shapes. It was coined in the mid-20th century to describe an extremely heavy U.S. prairie snowfall. In 1977, people started calling the white correction fluid used to cover typewritten mistakes whiteout, though the brand name is "Wite-Out."
