Update: Colorado River under a red flag warning until Saturday evening, increased fire danger

Published May 24, 2025

At 3:08 a.m. on Saturday, the National Weather Service issued an updated red flag warning valid between noon and 8 p.m. for Lower Colorado River.

Expect winds to be southwest 10 to 20 mph with gusts up to 35 mph and relative humidity 7 to 12 percent.

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

What is the significance of a red flag warning?

A red flag warning indicates that either extreme fire weather conditions are currently happening or will happen soon, as per 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 should you do under 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. 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. Responsible 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 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.
