Forest Preserve District of Cook County posted a statement to Facebook Thursday, regarding trail use amid the heavy rainfall:

"Due to substantial rainfall over the past few days, many of our trails are flooded. Never attempt to cross flooded areas, as they may be deeper than they appear. Please refrain from using unpaved trails until conditions improve—if you are leaving prints (boot, tire or hoof), the trail is too wet to use.
