*Small Stream Flood Advisory* for minor flooding of poor drainage areas for Southcentral St. Louis county in Northeast Minnesota...This includes the city of Duluth until 815 PM CDT Tonight.

At 2 PM CDT a trained weather spotter reported that Keene Creek in Duluth had overflowed its banks and water was flooding private property.  The flooding was occurring near the intersection of Getchell and Saint Louis River Roads.

Minor flood will continue along portions of Keene Creek and possibly other creeks in the Duluth area through early This Evening.  This includes the following streams and drainages...Chester Creek...Rocky Run...Mission Creek...Stewart Creek...Midway River...Buckingham Creek...Keene Creek...Pine River...Tischer Creek...Amity Creek...and East Branch Amity Creek.

In hilly terrain there are hundreds of low water crossings which are potentially dangerous in heavy rain.  Do not attempt to travel across flooded roads.  Find alternate routes.  It takes only a few inches of swiftly flowing water to carry vehicles away.
