Red flag warning in place for Colorado River for Saturday – increased fire danger

Published Aug 1, 2025

At 1:22 p.m. on Friday, the National Weather Service released a red flag warning valid for Saturday between 1 p.m. and 7 p.m. for Lower Colorado River.

The NWS states that the warning was issued for gusty winds, low relative humidity and dry fuels. Winds are forecasted to be southwest 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,” states the NWS.

What is the significance of a red flag warning?

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 actions are necessary during a red flag warning?

A red flag warning demands vigilance and immediate readiness to respond to potential fires. The NWS provides these vital guidelines to minimize fire hazards 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. 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. Properly extinguish outdoor fires:

To prevent inadvertent fires, diligently douse all outdoor fires. Quench them with a copious deluge of water and stir to guarantee complete cooling. Submerge charcoal until it’s thoroughly bereft of residual heat. Never depart from live charcoal unattended.

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.
