St. Croix and Pierce counties' fire outlook is a bit better than much of the state. But at "high" risk instead of "very high," the danger is real. The Department of Natural Resources on May 14 asked the public to stay vigilant and avoid burning because of wildfire danger across Wisconsin, particularly in the northern two-thirds of the state. The increased fire danger is due to the low relative humidities expected across the state, with the lowest values expected across northern Wisconsin. Temperatures will be warm and the air over Wisconsin will be dry, which are weather conditions that aid in the spread of fires.
