National Weather Service survey teams have determined nine tornadoes occurred across north central and northeast Illinois Wednesday evening.  These findings are the result of extensive ground damage surveys along three separate supercell paths: Amboy to Sheridan, Troy Grove to Mazon, and Pontiac to Cissna Park.

  • Pontiac: EF-2
  • Marseilles to Seneca: EF-2
  • Cissna Park: EF-1
  • West Brooklyn: EF-1
  • Ottawa: EF-1
  • Troy Grove: EF-1
  • Ottawa 5 NW:  EF-1
  • Mazon: EF-0
  • Sheridan:  EF-1

The NWS says ground survey data will be augmented with aerial photography and satellite imagery next to complete the survey documentation process over the next few days as these data sources become available.  It is possible minor adjustments to existing tornado paths may take place based on new photographic evidence.  It is even possible the number of tornadoes could increase.

Kane County was hit with about an inch to 2 inches of rain, according to the NWS.
