A week of warmer and dry weather brings a welcome dose of spring to the region — but the combination this time of year can increase the risk of wildfires.

The Wisconsin Department of Natural Resources on Tuesday asked the public to check fire conditions before conducting any outdoor burning activities. Those in an area of High or Very High fire danger should stay vigilant and avoid outdoor burning, they advised in a news release.

A quick check of the DNR’s website showed Florence, Marinette and Forest counties all considered High fire danger, with Vilas, Oneida and other counties to the west rated Very High.

Spring is the most critical fire season in Wisconsin, according to the DNR. So far in 2025, 658 wildfires have burned 2,220 acres of land in that state.

Monday, the Ackley fires burned an estimated 23 acres of swamp grass and cattails over a 4.5-mile stretch of highway near Ackley Road east of Ashland, the DNR stated in the release. Air patrol identified several different start points along the highway ditch, which grew into four separate fires. Ten threatened structures were saved through the joint efforts of DNR fire crews, the Ashland County sheriff’s department and the Bad River, Ashland, Saxon and Kimball fire departments.

Even a few days between precipitation can dry out grasses, pine needles and leaf litter, creating hazardous conditions. Add low humidity and variable winds to the mix, and fire danger increases significantly, the DNR advises.

The seven-day forecast shows no precipitation for much of central and northern Wisconsin, exacerbating the conditions in areas already in High or Very High fire danger.

What’s true for northern Wisconsin probably applies to much of the Upper Peninsula as well.

This elevated fire danger will continue until there is significant rainfall, and the DNR is continuing to suspend burn permits in 30 counties where it has burn restriction authority.

Actions the public can take to help prevent wildfires include:

— Embers from any fire — especially burn piles and campfires — can easily get out of control and cause a wildfire if not properly extinguished. The DNR asks that all outdoor burning be avoided until conditions improve.

— Outdoor enthusiasts should be extra careful with off-road vehicles or equipment that can create a spark and start a fire. Operate equipment — chainsaws, off-road vehicles, lawnmowers, etc. — early in the morning or late in the day to avoid sparks at peak burn hours. Secure dragging trailer chains.
