CHEYENNE, Wyo. (AP) — More firefighting resources are being sent to help battle a 2,000-acre wildfire burning in the Medicine Bow National Forest.

The fire is located about 30 miles south of Glenrock in Converse County. It was spotted on Sunday and tripled in size on Monday because of strong winds.

Residents of widely scattered ranches and cabins in the area were advised to evacuate Monday afternoon. A shelter has been set up in Douglas.

There are more than 200 firefighters on the scene, aided by six helicopters and two bulldozers.

On Tuesday, two single-engine air attack planes are joining in.

The firefighting effort will be challenged again by another day of hot, dry, windy conditions. The National Weather Service has posted a red flag warning for much of southern Wyoming.
