NORTH GEORGIA DUE TO LOW RELATIVE HUMIDITIES…

Relative Humidities of 30 percent or less can be expected for

4 or more hours this afternoon into the evening. Winds will be E

to SE at 5 to 10 MPH.

With dry fuels, high fire danger conditions can be expected.

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.”

What counties are affected?

The following counties are included in the hazardous weather outlook:

Banks, Barrow, Bartow, Carroll, Catoosa, Chattooga, Cherokee, Clarke, Cobb, Dade, Dawson, DeKalb, Douglas, Fannin, Floyd, Forsyth, Gilmer, Gordon, Greene, Gwinnett, Hall, Haralson, Jackson, Lumpkin, Madison, Morgan, Murray, Newton, North Fulton, Oconee, Oglethorpe, Paulding, Pickens, Polk, Rockdale, South Fulton, Taliaferro, Towns, Union, Walker, Walton, White, Whitfield, Wilkes
