On his Longmont Rain & Snow Facebook page, retired National Weather Service meteorologist Dave Larison reported 18 inches of snow in north Longmont as of 6 p.m. Sunday, moving it to third place on his list of double-digit snowstorms since 1990.

All Regional Transportation District bus routes also were suspended Monday morning.

Crews have been plowing and applying chemical treatments to Longmont streets since Saturday evening, with a focus on keeping through-travel lanes open, the city stated on its storm update webpage. Focus was set to turn to widening through-lanes on snowpacked arterial roads as the snowfall abated, according to the post, which also stated lower-traffic streets are snowpacked and urged motorists to use caution on overpasses, bridges, and at intersections.

Longmont Public Safety in a Facebook post on Sunday advised residents not to tackle the roads, stating it had to put chains on its 50,000- to 80,000-pound fire trucks for mobility. 

A number of roads and highways throughout the state were closed Monday morning in response to the storm, according to the Colorado Department of Transportation, as were the runways at Denver International Airport. The runways are expected to be closed through at least 2 p.m., according to DIA.
