Wildfire spreads in Caldwell County, NC

 A wildfire that started Friday evening continued growing Sunday in northwest Caldwell County and has spread to 150 acres, authorities say.

The U.S. Forest Service is working to control the blaze, off Globe Mountain Road, near Blowing Rock. Forest Service officials said Sunday morning they have set up a containment line around the fire. That containment line covers a 250-acre area, and Forest Service officials said they expect all that area to burn over the next few days.
The fire started late Friday night. It had spread to about 50 acres Saturday, then grew again Sunday morning.
The National Weather Service issued an advisory Sunday for an increased wildfire threat. Humidity levels are very low across the region, and rainfall for the last few months has been well below average. Breezy conditions also are forecast Sunday.
Authorities say no buildings have been consumed by the fire.
