The Department of Natural Resources is issuing a fire weather advisory for many of the northern counties in Wisconsin, including Marathon.
The DNR lists Marathon County as a county with high fire danger, along with Barron, Chippewa, Menominee, Rusk, Shawano and Taylor counties.
Many northern counties are listed as very high danger, including Ashland, Bayfield, Burnett, Douglas, Florence, Forest, Iron, Langlade, Lincoln, Marinette, Oconto, Oneida, Polk, Price, Sawyer, Vilas and Washburn counties.
Northern sandy pine areas are always the slowest to green up, DNR officials say, and mixed with low humidity and potential for high winds, fire danger is at its highest.
The DNR has responded to 281 wildfires burning more than 3,358 acres so far this year, according to a press release posted on the DNR website.
The DNR has also suspended annual burning permits in areas where it has jurisdiction to issue them.
