Severe impacts from snow squalls threaten lives and property on our Nation's high speed interstates and highways every winter season. Travel delays, disruptions to commerce, and damage to highway infrastructure cost millions of dollars nationwide. Beginning November 1, 2018, Snow Squall Warnings will be issued when whiteout conditions from heavy snowfall and gusty winds coincide with FLASH FREEZES. Poor visibility and flash (sudden) freezes on highway road surfaces can be deadly. Snow squalls can develop and move quickly, similar to warm season severe weather. Snow Squall Warnings will be active for 30 to 60 minutes, similar to Severe Thunderstorm Warnings. A Snow Squall Warning means: DELAY HIGHWAY TRAVEL or SAFELY EXIT before the snow squall arrives. Snow squalls pose serious threats to personal safety and property and produce costly transportation disruptions due to multi-vehicle pileups. There is no safe place on a highway when snow squalls are approaching.
