Update: Arkansas River Valley placed under a red flag warning Thursday – increased fire danger

Published Apr 23, 2026

On Wednesday at 11:02 p.m. the National Weather Service released an updated red flag warning valid for Thursday between 11 a.m. and 9 p.m. for Upper Arkansas River Valley including Lake County and Chaffee County.

Winds are expected to be west 20 to 30 mph with gusts up to 60 mph and relative humidity as low as 10%.

“Extreme fire danger is expected. Fires will uncontrollably spread and be very destructive,” explains the NWS.

What does a red flag warning mean?

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. Secure burn barrels:

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. Mindful 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 desert a blaze:

Avoid abandoning any fire without supervision. Even minor sparks or drifting embers can incite nearby foliage or grass, setting off a rapidly spreading fire.

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.
