This warning is in effect until Thursday at 10 a.m.

What does a red flag warning indicate?

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?

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. 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.
