BULLETIN - EAS ACTIVATION REQUESTED
Flash Flood Warning
National Weather Service Fort Worth TX
629 AM CDT SUN AUG 13 2017

The National Weather Service in Fort Worth has issued a

* Flash Flood Warning for...
  Northern Hunt County in north central Texas...
  Northern Hopkins County in north central Texas...
  Delta County in north central Texas...
  Fannin County in north central Texas...

* Until 1030 AM CDT.

* At 628 AM CDT, Doppler radar indicated additional heavy rain was 
  falling on areas that have already seen considerable rainfall this 
  morning. Ladonia in Fannin County has tallied more than 7 inches 
  of rain in the last 24 hours. Another automated gauge near 
  Greenville in Hunt County is up to 6.75 inches. The additional 
  rainfall will lead to excessive runoff and cause flash flooding. 
  Low-lying areas are most vulnerable to rapidly rising water. Some 
  low-water crossings may flood and become impassable.

Numerous creeks and streams are swollen or out of their banks. Be 
aware of areas that tend to flood readily and take alternate routes.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Turn around; don't drown. Most flood deaths occur in vehicles. Be 
especially cautious before daybreak when the darkness makes it more 
difficult to discern the dangers of flooding.

Please report flooding to your local law enforcement agency when you 
can do so safely.
