Crews battling wildfires in North Georgia are expected to endure another day of winds and dry conditions Saturday as several problem areas continue.

Relative humidity will fall to about 30 percent Saturday, Georgia Forestry Commission spokeswoman Heather Cowart said Friday. Also, winds will be out of the north at 8-12 mph. No rain is in the forecast.

The biggest headaches continue to be the Rough Ridge fire in Fannin County and the Rock Mountain fire in Rabun County.

Rough Ridge is reported at 27,870 acres and 75 percent contained, Cowart said in a media release.

The Rock Mountain fire, which has prompted some evacuations, is reported at 19,184 acres and 40 percent contained, according to the U.S. Forest Service.

Crews are using strategic burnout operations, which will depend on weather and may be delayed if conditions are not favorable, the USFS said.

More than 560 people are involved in battling this fire, and equipment includes 44 engines and seven helicopters, according to the USFS.

Pre-evacuations have been issued for some areas in Rabun County stretching to the North Carolina state line.

GFC crews responded to four new fires statewide Friday.
