What does a red flag warning indicate?

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. 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. Mindful handling 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:

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.
