 The NWS has issued a flood watch from late Wednesday night through
Thursday afternoon for portions of central and east-central
Illinois, including the counties of Cass, Christian, DeWitt, Fulton,
Knox, Logan, Macon, Marshall, Mason, McLean, Menard, Morgan, Peoria,
Piatt, Sangamon, Schuyler, Scott, Stark, Tazewell and Woodford in
central Illinois and the east-central Illinois counties of Champaign
and Vermilion.A storm system will bring an inch to an inch and a
half of rainfall to an area with plenty of snow still on the ground.
Some areas under stronger showers may see locally higher amounts.
The ground is already saturated from recent snowmelt, and warm
temperatures and rain will work together to melt the remaining snow
late Wednesday night and into Thursday. Almost all of the water will
become runoff. Thunderstorms producing a lot of precipitation
quickly will intensify the threat for flooding.
Area creeks and rivers will likely see rises associated with the
rainfall and snowmelt. Water will fill ditches and possibly cover
roads, particularly in low-lying areas. Urban areas with poor
drainage and underpasses may also have problems with rising water.

 Precautionary, preparedness actions: A flood watch means
there is a potential for flooding based on current forecasts. You
should monitor later forecasts and be alert for possible flood
warnings. Those living in areas prone to flooding should be prepared
to take action should flooding develop.
