Colorado road and utility crews are preparing for a heavy May snowstorm expected to bring rain and snow from Tuesday into Wednesday [1].

This late-season storm poses significant risks because the expected snow is heavy and wet. Such conditions often lead to tree branches snapping and falling onto power lines, which can cause widespread electrical outages and hazardous road conditions across the state [3].

State and city road crews, fire crews, and Xcel Energy teams have begun mobilization to manage the impact [1]. The storm system is moving from the Sierra Nevada and is projected to hit Southern Colorado, the Colorado foothills, and the Front Range, including Denver [1].

Snowfall totals vary by region. Denver could see between three and six inches of snow [4]. However, the Colorado foothills may experience more severe accumulations, with forecasts suggesting a foot or more of snow [5].

Weather officials expect rain and snow to persist through Tuesday and Wednesday, coinciding with Cinco de Mayo on May 5 [1]. The combination of rain and heavy snow during a period when residents have typically transitioned to spring activities increases the likelihood of traffic disruptions and infrastructure stress.

Utility crews from Xcel Energy are specifically preparing for the potential of power failures caused by the weight of the wet snow on vegetation [2]. Local authorities said residents should remain vigilant as the storm moves through the region mid-week [1].

“Colorado foothills could receive a foot or more of snow”

A significant snow event in May is atypical for the region and creates a unique set of hazards. Because spring foliage may have already begun to bloom, the surface area of tree branches is larger, making them more susceptible to breaking under the weight of heavy, wet snow compared to mid-winter storms. This increases the probability of power grid failures and requires a more intensive mobilization of utility crews than a typical late-season flurry.
