GRANITE FALLS — A brush fire near Granite Falls burned around 146 acres of land on Sunday afternoon, the Granite Falls Fire Department said. While the cause of the fire is under investigation, foul play and intentional open burning are not suspected, the Fire Department said.

In a news release, the Fire Department said power poles, fence posts, and multiple hunting stands burned, but no structure fires were involved. No injuries were reported.

Several residential and grass fires were reported around Minnesota over the weekend. Most of the state remained in a Red Flag warning on Monday, and the National Weather Service issued a fire weather watch for Tuesday, due to high winds and dry conditions.

The Granite Falls Fire Department got a call of a brush fire near Highway 167 in Yellow Medicine County around 2:23 p.m. Sunday, the Fire Department said in a news release. Multiple agencies were called in for aid, including fire departments from Hanley Falls, Sacred Heart, Wood Lake, Clarkfield, Renville, Maynard, Montevideo and Upper Sioux Emergency Management and Wildland Fire. The Minnesota Department of Natural Resources, Granite Falls Police, the Yellow Medicine County Sheriff’s Office, Minnesota State Patrol, MnDOT and Xcel Energy also responded to the fire.

Several defensive operations were established near buildings, but there were no structure fires in the incident, the Fire Department said.

“At final count, 23 grass rigs, dozens of tankers and engines and two helicopters responded to the scene,” the Fire Department said. DNR airborne resources and wildland engines stayed in the area to monitor the fire scene.

Yellow Medicine County was one of a few different locations around Minnesota that reported fires over the weekend. The list of incidents included house fires in Minneapolis and Alexandria. A grass fire Sunday in St. Louis County north of Duluth caused dozens of people to be evacuated, the Minneapolis Star Tribune reported.

The fire in St. Louis County, located near Brimson, was still out of control on Monday, the Star Tribune reported. The Minnesota Interagency Fire Center said Monday that the fire was about 1 square mile, or 750 acres, in size.

The NWS Office in Sioux Falls said a fire weather watch will be in effect Tuesday morning through Tuesday evening, due to windy and dry conditions. In Marshall, temperatures are forecast to reach a high of 93 degrees on Tuesday, with wind gusts as high as 30 miles per hour.

Lower temperatures and a chance of rain are still on the horizon. NWS forecasts said there is a chance of showers and thunderstorms Wednesday night and Thursday, with temperatures getting back down into the 60s and 70s.
