Red flag warning for Northwest Colorado for Tuesday – high fire danger

Published Aug 3, 2026

On Monday at 12:01 p.m. the National Weather Service issued a red flag warning valid for Tuesday between 1 p.m. and 7 p.m. for White River and Colorado River Headwaters as well as Routt County.

The NWS states that the warning was issued for gusty winds, low relative humidity and dry fuels. Expect winds to be west 10 to 20 mph with gusts up to 30 mph and relative humidity 7 to 12%.

“Any fire that develops will catch and spread quickly. Outdoor burning is not recommended,” says the NWS.

What is the significance of a red flag warning?

A red flag warning signifies that either extreme fire weather conditions are currently in effect or will be shortly, as stated by the NWS. Warm temperatures, very low humidities, and stronger winds are expected to combine to produce an increased risk of fire to spread 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:

If burning is permitted in your area, ensure that all burn barrels have a weighted metal cover, complete with holes no larger than 3/4 of an inch.

2. Mindful handling of smoking materials:

Never discard lit cigarette butts outside, and avoid tossing cigarettes or matches from a moving vehicle. These seemingly small actions can lead to dry grass ignition, potentially sparking a wildfire.

3. Properly extinguish outdoor fires:

To thwart accidental fires, diligently extinguish all outdoor fires. Suffocate them with an ample deluge of water and stir to ensure complete cooling. Submerge charcoal in water until it’s entirely devoid of heat. Never leave live charcoal unattended.

4. Never desert a blaze:

Avoid abandoning any fire without supervision. Even minor sparks or drifting embers can incite nearby foliage or grass, setting off a rapidly spreading fire.

Understanding the gravity of a red flag warning and adhering to these precautions is pivotal in reducing the risk of wildfires during these hazardous conditions. Prioritize safety, stay informed, and act responsibly to protect lives and property.
