JACKSON, Wyo. \u2014 Teton Interagency fire managers have amped up the fire danger rating to "high" for the Bridger-Teton National Forest, Grand Teton National Park, National Elk Refuge, and remaining portions of the Teton Interagency Dispatch area. Hot temperatures and dry, windy conditions, combined with summer vegetation curing, increase the potential for fire activity. A high fire danger rating means fires can start easily and spread quickly. Unattended campfires and brush fires are likely to escape. Fires can become serious and difficult to control unless they are quickly extinguished. When determining fire danger, fire managers use several indicators 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 availability of firefighting resources across the country. In areas where campfires are allowed, fires should never be unattended and must be completely extinguished. The charred remains of a campfire must be repeatedly doused with water and stirred into the campfire ring in order to be completely extinguished. All embers and logs should be broken up. Campers should \u201ccold trail\u201d the remains of the fire, which refers to carefully placing the back of your hand near the ashes and campfire debris to feel for any remaining heat before leaving the site.
