Update: Red flag warning affecting Central Colorado Tuesday – increased fire danger

Published Jun 30, 2026

On Monday at 8:57 p.m. an updated red flag warning was released by the National Weather Service valid for Tuesday between noon and 9 p.m. for South and Southeast Grand/West Central and Southwest Boulder/Gilpin/Clear Creek/Summit/North and West Park counties above 9,000 feet, Grand and Summit counties below 9,000 feet, Central and Southeast Park County and Jefferson and West Douglas counties above 6,000 feet/Gilpin/Clear Creek/Northeast Park counties below 9,000 feet.

Winds are forecasted to be southwest 10 to 20 mph with gusts up to 35 mph and relative humidity as low as 9%.

“A warm and dry airmass will coincide with gusty west and southwest winds today and Tuesday, and could potentially continue through Friday. Sustained winds are expected to be 15 to 30 mph across much of the high country this afternoon, with gusts up to 45 mph, strongest for exposed areas and higher elevations. These conditions will drive very high fire danger across the warned area. Any new starts or established fires will likely spread rapidly under these conditions,” describes the NWS. “Conditions will be favorable for rapid fire spread. Avoid outdoor burning and any activity that may produce a spark and start a wildfire.”

What does a red flag warning indicate?

A red flag warning means that extreme fire weather conditions are either occurring now or will shortly, according to the NWS. Warm temperatures, very low humidities, and stronger winds are expected to combine to produce an increased risk of fire spreading rapidly.

What are the recommended measures to take during a red flag warning?

During a red flag warning, it is crucial to exercise extreme caution and be prepared to take immediate action in case a fire starts. The NWS offers these steps you can take to lower the risk of fires igniting and ensure your safety:

1. Bolster burn barrel safety:

In areas where controlled burning is sanctioned, make certain that burn barrels sport a weighty metal cover, equipped with holes no larger than 3/4 of an inch.

2. Responsible disposal of smoking materials:

Steer clear of haphazardly discarding lit cigarette butts and avoid flinging cigarettes or matches from moving vehicles. These innocuous-seeming actions can kindle dry vegetation, potentially spawning a wildfire.

3. Prudent fire extinguishing practices:

To safeguard against accidental fires, diligently extinguish all outdoor fires. Drown them with an ample amount of water and stir to confirm that everything is cold to the touch. Submerge charcoal in water until it’s thoroughly cooled. Never dispose of live charcoal on the ground.

4. Never leave fires unattended:

Refrain from leaving any fire unattended. Even minor parks or embers might be carried into leaves or grass, kindling a fire that can swiftly expand.

Understanding the gravity of a red flag warning and adhering to these precautions is pivotal in mitigating the risk of wildfires during these perilous conditions. Prioritize safety, stay well-informed, and act responsibly to safeguard lives and property.
