A spring storm began Monday, May 4, 2026, bringing rain, sleet, and heavy snow to the Colorado foothills and California's Bay Area mountain peaks.
The system disrupts regional infrastructure and travel during a transition season, posing risks to power grids and local school schedules. Heavy, wet snow in May can cause significant damage to trees and power lines due to its weight.
Two cold fronts moving through the region triggered the weather event [1]. This activity prompted the issuance of a Winter Storm Watch for Tuesday afternoon [1].
Forecasts for snow accumulation vary by region. Some reports indicate an accumulation of four to eight inches of heavy, wet snow [1]. However, other forecasts suggest that the Colorado foothills could see a foot or more of snow [2].
In California, the storm's impact is more localized, with snow primarily dusting the mountain peaks of the Bay Area [3]. Meanwhile, Xcel Energy crews in Colorado have been preparing for the arrival of rain and snow throughout the week [5].
The storm has already led to multiple power outages and school delays [4]. These disruptions are common when spring storms bring unseasonable freezing temperatures and heavy precipitation to areas not fully prepared for winter-like conditions.
Local officials continue to monitor the situation as the cold fronts pass. Residents in affected areas are advised to stay updated on the Winter Storm Watch as the system moves through the region.
“Colorado foothills could see a foot or more of snow”
This weather event highlights the volatility of spring transitions in high-altitude regions. When heavy, wet snow falls in May, it often creates a higher risk of power outages compared to mid-winter storms because trees have already begun to leaf out, making them more susceptible to breaking under the weight of the snow.
