...FLOOD WATCH IN EFFECT FROM 7 PM CDT THIS EVENING THROUGH MONDAY 
MORNING...

The National Weather Service in Wichita has issued a

* Flood Watch for a portion of Southeast Kansas, including the 
  following areas, Allen, Chautauqua, Elk, Labette, Montgomery, 
  Neosho, Wilson and Woodson.

* From 7 PM CDT this evening through Monday morning.

* Numerous thunderstorms will develop by this evening and then 
  continue well into tonight. Thunderstorms will gradually taper off 
  from west to east by early Monday morning. Hourly rainfall rates 
  of one to two inches per hour could lead to an increased risk of 
  flash flooding. Rises on creeks, streams, and rivers are likely as 
  well, with some potentially reaching flood stage.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Be especially cautious at night when it is harder to recognize the 
dangers of flooding.

In hilly terrain there are hundreds of low water crossings which are 
potentially dangerous in heavy rain. Do not attempt to cross flooded 
roads. Find an alternate route.
