Avalanche conditions are generally safe. You can trigger small, wet avalanches in isolated steep terrain. Avalanches that you trigger will typically be small and manageable by avoiding consequential terrain and avoiding unsupportive snow.
A trough of low pressure over the Great Basin is driving weather across Colorado Monday afternoon. Banded precipitation transitions to convective snow showers Monday afternoon. These favor the Northern and Central Mountains with 3 to 6 inches of snow possible by Tuesday morning. The Southern Mountains will not see appreciable snowfall.
Snowfall continues along the Front Range into Tuesday morning, aided by upslope easterly winds and abundant moisture. 6 to 10 inches of snowfall with localized amounts over a foot does not seem unrealistic, especially above treeline. Some snowfall spills further west to the Mosquito and eastern Sawatch Ranges, with a few inches possible Tuesday morning. High temperatures will be in the 30s Fahrenheit across the North, with 40s common in the South. Snowfall ends with gradual clearing Tuesday night and lows in the 20s. Temperatures gradually warm through the rest of the week as a breezy northwesterly flow becomes more westerly.
Snowpack and Avalanche Discussion
After a weak freeze, temperatures will make it into the low 50s on Tuesday, so expect wet avalanche problems to arise early in the day. These are managed by timing your travel early and exiting terrain when signs of instability like unsupportive, wet snow start appearing. Unless you find yourself in steep, high consequence terrain, avalanche problems are generally manageable.
