JACKSON, Wyo. — High temperatures and gusty winds doubled the size of the Lone Star Fire in Yellowstone over the weekend.

Smoke from the fire temporarily closed Grand Loop Road between Old Faithful and West Thumb on Saturday. That section of the road has reopened but could close again at any time.

The fire spread on Sunday by torching and limited crowning as it burned to the east and northeast, with a significant column building in the afternoon. It has now grown to an estimated 3,346 acres.

Joe Rock, of West Yellowstone Smoke Jumpers, is now assigned to the fire along with 52 personnel. Mother Nature is expected to assist Monday night through Tuesday as a severe cold system is expected to bring rain and perhaps snow to the area.

Firefighters continue to keep a watchful eye on assets in the Old Faithful area.
