The National Weather Service warned of high fire danger in Cobb County for the afternoon and evening today due to low relative humidity. The forecast is for humidity 25 percent and below.

According to the National Parks Service, low humidity increases the risk of fire because of the loss of moisture in flammable plant life.

The NPS website has a fire hazard page that describes the process as follows:

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 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.air when the humidity is high.
