In Kane County a large tree limb was down in Batavia at Millview Drive and Town Avenue, several trees were reported down in East Dundee at Route 25 and Sunset Park Drive, wires on trees with fires were reported east of Maple Park at Route 38 and Schrader Road, and a large tree was down in the roadway in Elgin at Liberty Street and Sherman Avenue.
