Denver Weather Alert: Rain and Possible Snow Expected May 18–19, 2026 – Here’s What to Expect
Denver and surrounding areas are under a late-season weather alert as a powerful system brings rain to the city and the potential for significant snowfall in higher elevations. Meteorologists warn of 3–12 inches of snow above 9,000 feet in the northern Front Range, including popular ski resorts and mountain communities. Residents should prepare for wet roads, reduced visibility and possible travel disruptions.
Key Forecast Details: Rain in Denver, Snow in the Mountains
- Denver metro: ½–1 inch of rain expected, with temperatures hovering in the mid-50s (°F).
- Northern Front Range (above 9,000 ft): 3–12 inches of snow likely, with accumulation dependent on elevation and timing.
- Timing: Precipitation begins late Sunday night, intensifying Monday morning and tapering by evening.
- Road conditions: Icy patches possible on mountain highways (e.g., I-70, US-36) and elevated roads in Denver.
This system is unusual for late May, as Denver typically sees its last snowfall in early April. The combination of moisture from the Pacific and a cold air mass dropping from the north is creating unpredictable conditions.
Who Is Most Affected?
Urban Areas (Denver/Aurora)
Residents should expect heavy rain, which may lead to localized flooding in low-lying areas. The National Weather Service (NWS) has issued a flash flood watch for the Denver metro area, particularly for basins like Sand Creek and Bear Creek.
Mountain Communities (Above 9,000 ft)
Towns like Breckenridge, Keystone, and Vail are under a winter storm warning. Snowfall could disrupt hiking, trail access, and early-season mountain activities. The Colorado Department of Transportation (CDOT) has pre-positioned crews on I-70 and US-36.
Suburban and Exurban Zones
Areas like Boulder, Golden, and the foothills may see a mix of rain and snow, particularly on higher elevations. Wind gusts up to 40 mph could create blowing snow in open areas.
What Should You Do to Prepare?
For Denver Residents:
- Check Denver’s emergency alerts for real-time updates.
- Clear gutters and drains to prevent basement flooding.
- Keep an emergency kit with flashlights, batteries, and non-perishable food.
- Avoid driving through flooded roads—turn around, don’t drown.
For Mountain Travelers:
- Monitor CDOT’s road conditions before heading out.
- Carry chains or an AWD vehicle if traveling above 9,000 feet.
- Notify someone of your travel plans and expected return time.
- Pack warm layers, even for short trips—temperatures can drop rapidly.

As of now, no widespread closures have been announced. However, check Denver Public Schools and local employers for updates.
Is this a record-breaking event?

Looking Ahead: What’s Next?
After Monday’s storm, a ridge of high pressure will bring drier, warmer conditions to Colorado by midweek. However, meteorologists are monitoring a possible return of unsettled weather by the end of next week. Stay tuned to NWS Boulder for updates.
Pro Tip: If you’re planning outdoor activities in the mountains, consider rescheduling until conditions stabilize. Safety should always be the priority.
