...URBAN AND SMALL STREAM FLOODING EXPECTED...
Thunderstorms with heavy rain will cause minor flooding in the
following counties...
Freeborn...Faribault...Sibley...Blue Earth...Waseca...Nicollet...
* Until 700 PM CDT.
* At 223 PM CDT, Doppler radar and automated rain gauges indicated
heavy rain due to thunderstorms. This will cause urban and small
stream flooding in the area. As much as 2 to 3 inches of rain have
already fallen across portions of the area, and additional
rainfall is expected through the afternoon.
* Some locations that will experience flooding include...
Mankato, Albert Lea, North Mankato, Lake Crystal, Eagle Lake,
Wells, Mapleton, Winthrop, New Richland, Nicollet, St. Clair and
Gibbon.
PRECAUTIONARY/PREPAREDNESS ACTIONS...
Turn around, don't drown when encountering flooded roads. Most flood
deaths occur in vehicles.
Excessive runoff from heavy rainfall will cause flooding of small
creeks and streams, urban areas, highways, streets and underpasses as
well as other drainage areas and low lying spots.
In hilly terrain there are hundreds of low water crossings which are
potentially dangerous in heavy rain. Do not attempt to cross flooded
roads. Find an alternate route.
