The Red Flag Warning, issued by the National Weather Service (NWS) Pueblo CO, is in effect for critical fire weather conditions. It was sent on April 10, 2026, at 11:47 PM MDT and becomes active from 11 AM MDT on April 12, 2026.
Affected Areas
This warning impacts the Upper Arkansas River Valley including Lake County and Chaffee County; Teller County/Rampart Range including Pikes Peak and Florissant Fossil Beds National Monument; and the Southern Front Range including Sangre De Cristo Mountains/Wet Mountains/La Veta Pass. It covers Fire Weather Zones 220, 221, and 225 in Colorado.
What You Should Do
Residents should prepare for critical fire weather conditions, as strong winds, low relative humidity, and warm temperatures can lead to extreme fire behavior. Take steps to mitigate fire risks in the affected areas.
Expected Conditions
Gusty southwest winds of 20 to 30 mph with gusts up to 45 mph are anticipated, along with relative humidity as low as 11 percent. These conditions will elevate fire danger, causing fires to spread rapidly and erratically.
