BULLETIN - EAS ACTIVATION REQUESTED
Flash Flood Warning
National Weather Service Wichita KS
1055 PM CDT TUE AUG 14 2018

The National Weather Service in Wichita has issued a

* Flash Flood Warning for...
  Labette County in southeastern Kansas...

* Until 645 AM CDT Wednesday.

* At 1049 PM CDT, Doppler radar indicated thunderstorms producing 
  heavy rain spreading southeast across Western Labette County where 
  3 to 5 inches of rain have already fallen. Flash flooding is 
  expected to begin shortly, especially in Western Labette County.

* Some locations that will experience flooding include...
  Parsons, Oswego, Chetopa, Altamont, Edna, Mound Valley, Bartlett,
  Labette, Parsons Tri City Airport, Angola, Dennis and Big Hill
  Lake.

Additional rainfall amounts from 2 to 4 inches are possible in the 
warned area.

The thunderstorms that are moving southeast into Labette County have 
caused major flash flooding in Northern Montgomery County where many 
rescues have been required.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Be especially cautious at night when it is harder to recognize the 
dangers of flash flooding. Never drive through flooded roads or 
highways, especially at night!

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.

A Flash Flood Warning means that flooding is imminent or occurring.
If you are in the warned area move to higher ground immediately.
Residents living along streams and creeks should take immediate
precautions to protect life and property.
