Even though much of Minnesota received late-season snowfall, fire danger is expected to rapidly increase when the weather warms up, the snow melts and winds dry the dead standing grass and brush in open areas. Because of that, the Minnesota Department of Natural Resources (DNR) is placing burning restrictions over the east-central part of the state beginning at 4 p.m. Sunday, April 21. The restrictions cover 10 counties, including Anoka, Chisago and Washington. The burning restrictions mean the state will not issue permits for burning brush or yard waste. The restrictions normally last from four to six weeks until sufficient green vegetative growth occurs.
