Red flag warning in place for Northern Colorado until Monday evening – enhanced fire threat

Published Oct 20, 2025

A red flag warning was issued by the National Weather Service on Monday at 2:34 a.m. valid between 9 a.m. and 6 p.m. for Larimer County below 6,000 feet/Northwest Weld County, Northeast Weld County and Central and South Weld County as well as Morgan and Logan counties.

The NWS states that the warning was issued for wind and low relative humidity. Residents can expect winds to be northwest 25 to 35 mph with gusts up to 50 mph and relative humidity as low as 16 percent.

“Conditions will be favorable for rapid fire spread. Avoid outdoor burning and any activity that may produce a spark and start a wildfire,” 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 steps should you follow 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. Secure burn barrels:

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