Published Jun 9, 2026

A red flag warning was issued by the National Weather Service on Tuesday at 1:36 a.m. valid between noon and 8 p.m. for San Luis Valley including Alamosa/Del Norte/Fort Garland/Saguache.

“Elevated fire danger is expected. Fires will catch and spread rapidly and erratically,” explains the NWS.

What does a red flag warning mean?

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 should you do under 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 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. Mindful 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 safeguard against accidental fires, diligently extinguish all outdoor fires. Drown them with an ample amount of water and stir to confirm that everything is cold to the touch. Submerge charcoal in water until it’s thoroughly cooled. Never dispose of live charcoal on the ground.

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 pivotal in mitigating the risk of wildfires during these perilous conditions. Prioritize safety, stay well-informed, and act responsibly to safeguard lives and property.
