...THE FLASH FLOOD WARNING REMAINS IN EFFECT UNTIL 315 PM EDT FOR
ANTRIM COUNTY...

At 130 PM EDT, Antrim County emergency management reported rivers 
and creeks still overflowing their banks. Even though water is 
starting to recede, some roads may have the potential to be affected 
by flood waters. 

The rain will be ending through 3 pm but creeks, streams and rivers 
across the warned area may continue to rise due to the heavy rain 
that fell earlier today.

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, country roads, farmland, and other low lying
spots.
