RED FLAG WARNING: Dangerous Winds Expected Across Boulder and the Front Range Today

Severity: Severe
Significant threat to life and property
Onset: 11:00 AM (MDT), March 12

Boulder is under a Red Flag Warning today, and this is not just another windy Front Range afternoon. Forecasters are warning of dangerous wind conditions combined with extremely dry air, creating an elevated wildfire threat along with the potential for flying debris, travel hazards, and scattered power outages.

Conditions are expected to intensify late morning and continue through the day, with the strongest gusts likely along the foothills, open spaces east of town, and exposed roadways like Highway 36. Sudden crosswinds, blowing dust, and debris may create rapidly changing conditions with little warning.

Days like this demand attention. Even longtime Boulder residents who are used to wind events know how quickly situations can escalate.

What Makes Today Different

This Red Flag Warning signals a high-risk combination of strong winds, low humidity, and dry fuels — the exact conditions that allow fires to ignite and spread rapidly.

Expect:

• Powerful gusts capable of knocking down branches and unsecured objects
• Blowing dust and debris reducing visibility on roads and trails
• Isolated power outages where lines are impacted
• Sudden shifts in wind direction throughout the day

Calm periods may occur, but they can change quickly.

Immediate Steps to Take at Home

Preparation matters more on days like this. Take action now:

• Bring inside or secure patio furniture, umbrellas, and loose outdoor items
• Close and latch gates, windows, and garage doors
• Fully charge phones, laptops, and backup batteries
• Move vehicles away from trees and power lines
• Keep pets indoors during peak winds

A few minutes of preparation can prevent serious problems later.

If You’re Heading Out

Travel conditions may change quickly across Boulder and the Front Range:

• Use caution on exposed routes, especially Highway 36 and open north-south roads
• Watch for falling branches and sudden debris
• Cyclists and runners should expect strong crosswinds in open areas
• Avoid parking under trees or near power lines
• On trails, stay alert and avoid heavily wooded sections during peak gusts

Fire Danger Is the Biggest Concern

Today’s biggest risk isn’t inconvenience — it’s fire.

Under Red Flag conditions:

• Avoid outdoor burning or grilling
• Never discard cigarettes outdoors
• Do not use equipment that creates sparks
• Report any smoke or fire immediately

Fires can spread extremely fast in these conditions.

If Power Goes Out

Outages are possible today. Be ready:

• Keep flashlights and batteries accessible
• Use portable chargers for phones
• Keep refrigerator and freezer doors closed
• Check on neighbors if safe to do so

A Serious Reminder for Boulder

High winds are nothing new along the Front Range — but Red Flag days demand extra caution. Staying alert, preparing early, and making smart decisions today can protect homes, trails, and the entire Boulder community.
