Spring storm hits Colorado

April 29, 2019 - Weather could impact travel across much of the state

US 40 east of Steamboat

Unsettled weather is moving into the state. Just before 3 p.m. April 29, roads were slick on many high mountain highways, like US 40 southeast of Steamboat Springs.

Travelers may encounter hazardous driving conditions across the state due to an advancing spring snowstorm. Heavy snow is expected through Tuesday, April 30.

Snow may impact travel on interstates 70 and 25, and foothill regions from western Colorado through the central mountains, and across the Front Range. Snow totals will vary greatly depending on elevation and storm track.

Commercial traffic can expect chain laws to be enforced, and traction laws may be in place for passenger vehicles traveling along high mountain corridors. High winds are likely.
