Thunderstorms with heavy downpours have moved over the Rockford area this afternoon and radar indicates more storms are on their way. Due to the recent heavy rains experienced in that area, soils are saturated and rivers/streams nearly overflowing their banks. Additional rains will likely cause flooding over many parts of this area, thus the issuance of the Flash Flood Warning (red-shaded area on the highlighted map).

Following is the discussion prepared by the Chicago National Weather Service…

The National Weather Service in Chicago has issued a

* Flash Flood Warning for...
  Eastern Winnebago County in north central Illinois...

* Until 945 PM CDT

* At 552 PM CDT, Doppler radar indicated thunderstorms producing
  heavy rain moving slowly across the warned area. Up to one and a
  half inches of rain have already fallen over parts of Winnebago
  County earlier, which caused rapid minor flooding in Rockford
  earlier. Given the saturated ground conditions from the past few
  weeks, flash flooding is expected to begin shortly, especially in
  the Rockford metro.

* Some locations that will experience flooding include...
  Rockford, Loves Park, Machesney Park, South Beloit, Rockton,
  Rockford Airport, Roscoe, Cherry Valley, Winnebago, Davis Junction
  and New Millford.

Including the following interstates...
 I-39 between mile markers 115 and 123.
 I-90 between mile markers 1 and 2, and between mile markers 61 and
76.

This includes...  Rock Cut State Park, Rock Valley College, Rockford
