Published Jul 10, 2025

At 2:08 p.m. on Thursday, the National Weather Service released an updated red flag warning in effect until 9 p.m. for Upper Arkansas River Valley including Lake County and Chaffee County, Eastern San Juan Mountains and La Garita Mountains including Wolf Creek Pass and Creede and San Luis Valley including Alamosa/Del Norte/Fort Garland/Saguache.

“Fires will catch and spread quickly. Exercise extreme caution with any outdoor burning,” states the NWS.

What does a red flag warning mean?

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?

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 authorized in your vicinity, ensure that all burn barrels feature a weighted metal cover with holes no larger than 3/4 of an inch.

2. Responsible disposal 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. 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:

Avoid leaving any fire unattended. Even sparks or embers carried by the wind can ignite nearby leaves or grass, triggering a fire that spreads rapidly.

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.
