What is a Red Flag Warning?

A “Red Flag Alert” from the National Weather Service (NWS) is a critical warning indicating extreme fire danger due to a combination of weather conditions. This alert is issued when the forecasted weather includes low humidity, strong winds, dry fuels, or the potential for dry lightning strikes, creating a heightened risk for wildfire ignition and rapid spread. The criteria for a Red Flag Warning can vary by region, reflecting local climate, vegetation, and topography, but the underlying concern is consistently the potential for explosive fire growth.

When a Red Flag Warning is in effect, it signals to firefighting agencies, land managers, and the public to be on high alert. Residents in affected areas are advised to exercise caution with any outdoor activities that could produce a spark or flame. This includes postponing yard work, avoiding outdoor burning, and properly disposing of cigarettes. Additionally, local authorities might implement temporary restrictions to further reduce fire risks, such as bans on open fires or fireworks.

Understanding and adhering to the precautions during a Red Flag Alert is crucial for community safety, helping to prevent the outbreak and spread of wildfires, and protecting both people and property from the devastating effects of uncontrolled fires.

Why does low relative humidity increase the danger of fire?

The National Park Service published the following explanation of why low relative humidity increases the danger of fires:

“Relative humidity is important because dead forest fuels and the air are always exchanging moisture. Low humidity takes moisture from the fuels, and fuels in turn, take moisture from the air when the humidity is high. 

“Light fuels, such as grass and pine needles, gain and lose moisture quickly with changes in relative humidity. When the RH drops, fire behavior increases because these fine fuels become drier. 

“Heavy fuels, on the other hand, respond to humidity changes more slowly. To see significant changes in heavy fuel moisture, there must be significant moisture, usually from more than a single storm.”
