...THE FLASH FLOOD WARNING REMAINS IN EFFECT UNTIL 445 AM CDT FOR
CENTRAL FORD COUNTY...

At 229 AM CDT, Doppler radar indicates rain gradually diminishing 
over the warned area. Rain is expected to end completely over the 
next hour. 

Numerous reports of stranded cars and motorist rescues have been 
received across the Dodge City area. Storm spotters have reported up 
to 5 inches of rain in Dodge City.  Many low lying roadways are 
underwater. This is a very dangerous situation, especially at night, 
when it is very difficult to determine how deep the water is, or how 
fast it is moving. Dangerous runoff will continue over the next two 
hours. 

Some locations that will experience flooding include...
Dodge City and Ft. Dodge. 

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.

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.
