Several bands of rain associated with the remnants of Tropical Storm Gordon impacted Jasper County from September 7th through the 8th. The ground was saturated with nearly 3.00 to 5.00 inches of rain when a particularly heavy band of rain moved into southeast Illinois during the afternoon of September 8th. An additional 1.00 to 1.50 of rain in less than three hours produced flash flooding in southern and eastern Jasper county in the early afternoon. Water covered many roads, including IL State highway 130 south of Newton and IL State highway 33 east of newton.

The wider storm

Heavy rain impacted central and southeast Illinois as the remnants of Tropical Storm Gordon tracked from Arkansas during the afternoon of September 7th to southern Ohio by the afternoon of September 9th. The rainfall was further enhanced by a weak cold front dropping southward out of the Upper Midwest. Rainfall was heaviest south of I-70 in closer proximity to the track of the storm, with amounts ranging from 5 to 10 inches. Another area of heavy rain materialized northwest of the Illinois River as the cold front approached, with totals of 4 to 6 inches. Due to the prolonged period of heavy rainfall, flash flooding developed mainly along and southeast of a Newton to Flora line where numerous roads were closed due to high water.

Began near Newton (38.9686, -88.2215).
