HOLMES COUNTY...

At 951 PM EDT, local law enforcement reported flooding across 
portions of Holmes County.  The worst of the flooding appears to be 
north of Millersburg into the Holmesville area.  Little additional

recede.  Several roads remain closed and at least one vehicle has 
already been swept off the road by flood waters.  Over 3.5 inches of 
rain was measured in the area. Area streams and creeks...including 
Killbuck Creek will likely continue to rise for a few more hours 
before beginning to subside.  

Some locations that will experience flooding include...
Millersburg, Berlin, Walnut Creek, Sugarcreek, Killbuck, Holmesville,
Winesburg, Farmerstown, Baltic, Mount Hope and Charm.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Turn around, don't drown when encountering flooded roads. Most flood
deaths occur in vehicles.

Be especially cautious at night when it is harder to recognize the
dangers of flooding.
