An evacuation zone extended from north of Big Arm to Dayton along U.S. 93, along Montana 28, and along Lake Mary Ronan Road from mile marker 5 to U.S. 93.

Elmo was considered to be a level 3 evacuation status, which means people in that area should leave immediately. Others in the evacuation zone should be prepared to leave, the Polson Fire Department alerted.
