...THE FLASH FLOOD WARNING FOR SOUTHEASTERN SHERIDAN...GOVE AND
SOUTHWESTERN GRAHAM COUNTIES WILL EXPIRE AT 200 AM CDT...

The heavy rain has ended with light to moderate rainfall expected to 
continue through the rest of the night. Therefore flash flooding is 
no longer expected to pose a threat. However, with the large amount 
of rain that has occurred across the area, it is expected that the 
large amount of ponding water will be slow to recede. So will be 
issuing an areal flood warning shortly. Please continue to heed any 
remaining road closures.
