Interagency fire officials on the Bridger-Teton National Forest, in Grand Teton National Park and throughout Teton County have elevated the fire danger rating to extreme due to the lack of precipitation. Fire officials use several indices when determining fire danger such as the moisture content of grasses, shrubs and trees; projected weather conditions (including temperatures and possible wind events); the ability of fire to spread after ignition; and available fire-fighting resources. Partial Fire Restrictions remain in effect for both the Bridger-Teton National Forest and Grand Teton National Park including the use of open fire in all but permanent fire rings in established camping and picnic grounds. Meanwhile, personnel staffing the Little Horsethief Canyon Fire have been reduced to 262 now as fire activity continues to calm. 91% of the 3373 acre fire is now considered contained with full containment now anticipated by Saturday morning.
