Update: Red flag warning in place for San Juan and Gunnison Basin for Sunday – gusts may reach 45 mph

Published Jun 7, 2026

At 8:57 p.m. on Saturday, the National Weather Service released an updated red flag warning valid for Sunday between 10 a.m. and 10 p.m. for Northern San Juan and Gunnison Basin.

Expect winds to be southwest 20 to 30 mph with gusts up to 45 mph and relative humidity 11 to 16%.

“Elevated fire danger is expected. Fires will catch and spread rapidly and erratically,” comments 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:

In areas where controlled burning is sanctioned, make certain that burn barrels sport a weighty metal cover, equipped 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 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 reducing the risk of wildfires during these hazardous conditions. Prioritize safety, stay informed, and act responsibly to protect lives and property.
