Update: Red flag warning for Colorado River and Colorado River Headwaters until Thursday evening

Published Jul 10, 2025

At 2:16 a.m. on Thursday, the National Weather Service released an updated red flag warning valid between noon and 8 p.m. for Lower Colorado River and Colorado River Headwaters.

Expect winds to be west 10 to 15 mph with gusts up to 30 mph and relative humidity 8 to 13 percent.

“Any fire that develops will catch and spread quickly. Outdoor burning is not recommended,” comments 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 steps should you follow 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. Secure burn barrels:

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 disposal of smoking materials:

Prudently discard cigarette butts and avoid flinging cigarettes or matches from a moving vehicle. These seemingly innocuous actions can kindle dry grass, potentially triggering a wildfire.

3. Prudent fire extinguishing practices:

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:

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 paramount in averting wildfires during these perilous conditions. Prioritize safety, stay impeccably informed, and assume responsibility to shield lives and property.
