The National Weather Service issued a 'life-threatening' snow squall warning for parts of Colorado and Wyoming on Tuesday morning, alerting people to heavy snow and strong winds that could cause visibilities to plummet rapidly. Snow squalls can lead to deadly traffic accidents due to the sudden white-out conditions and icy roads.

Why it matters

Snow squalls are a dangerous wintertime weather hazard that can strike suddenly and last less than an hour. The sudden white-out conditions combined with falling temperatures can produce icy roads in just a few minutes, posing a serious threat to motorists. This warning highlights the need for residents in the affected areas to stay vigilant and monitor local weather forecasts closely.

The details

The snow squall warning was issued for southeastern Albany County and southwestern Laramie County in Wyoming, as well as northeastern Larimer County in Colorado. The alerts warned of 'intense bursts of heavy snow' accompanied by strong winds that could quickly become 'dangerous and life-threatening' for travel. Gusty winds over 50 mph were also expected, which could knock down tree limbs and blow around unsecured objects.

  • The snow squall warnings were issued at 7:45 a.m. local time on Tuesday, February 17, 2026.
  • The warnings were expected to remain in effect for around 30 minutes, although similar warnings could be issued in surrounding areas as the storm continues to progress.
