The NWS Reno NV released a red flag warning at 9:53 a.m. on Thursday valid for Friday between 2 p.m. and 9 p.m. for Surprise Valley California and Eastern Lassen County.

Residents can expect winds to be west 15 to 25 mph with gusts to 35 mph and humidity afternoon minimums 7 to 15%.

"The combination of gusty winds and dry fuels can cause fire to rapidly grow in size and intensity before first responders can contain them," adds the NWS.

This warning is in effect until Friday at 9 p.m.

What is the significance of a red flag warning?

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 steps should you follow during 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:

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. 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 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 paramount in averting wildfires during these perilous conditions. Prioritize safety, stay impeccably informed, and assume responsibility to shield lives and property.
