YELLOWSTONE NATIONAL PARK, Wyo. (AP) — Yellowstone National Park is reinstating fire restrictions and closing some hiking trails and backcountry campsites as hot, dry conditions raise the potential for wildfires.

Five small fires are burning within the park, the largest of which is the 25-acre Dewdrop Fire. As a precaution, the park closed some campsites and trail segments north and east of the blaze Monday.

As of noon Wednesday, charcoal grills will be prohibited in the park, and backcountry fires will be prohibited. Campfires will be allowed only in established fire grates or fire rings in picnic areas or campgrounds. Smoking will be allowed only in vehicles or along roads, near buildings, and in developed campgrounds or picnic areas if there is nothing on the ground within three feet that could burn.
