The storm poses significant risks, including flash flooding, damaging winds, and heavy snowfall in higher elevations. Over four million people in central and northern Arizona are under a Level 3 out of 4 flash flood risk. In Colorado, the San Juan River near Pagosa Springs is expected to rise to dangerous levels, prompting mandatory evacuations. Heavy snow in the San Juan, Sawatch, Wasatch, and Uinta mountain ranges could lead to power outages and hazardous travel conditions. Strong winds, with gusts up to 50 mph, may further exacerbate the situation by reducing visibility and causing travel disruptions.
