CHEYENNE, Wyo. (AP) — A wildfire burning in the Bridger-Teton National Forest in western Wyoming has become the largest in the state to date this year.

The Fontenelle Fire in the Wyoming Range made a 3-mile run on Wednesday and has now burned about 36 square miles of forest. An undetermined number of campers in the area were forced to flee but no structures have been lost or injuries reported.

Officials say more hot, dry and windy conditions are expected Thursday. There is no containment and more firefighting resources have been requested to help the more than 100 on hand.

Elsewhere, new fires have been reported in Albany and Platte counties, joining ongoing fires in Converse, Park and Washakie counties.

Red flag warnings have been posted for most of western, central and southern Wyoming.
