During the overnight hours of August 9th into the wee hours of the morning of the 10th, two separate and significant flash flooding events occurred in Madison County. The overnight/early morning hours event occurred in Northern Madison County, affecting locations from Harvest to Hazel Green/Meridianville and eastward to New Market. Widespread rainfall totals of 7-8 inches occurred over the span of a few hours, leading to significant flash flooding, resulting in numerous roads closed and several vehicles inundated with water. The second Flash Flooding event took place that evening over the city of Huntsville, specifically along Highway 431 in eastern Madison County, from California Street near Governors drive eastward along Hwy 431 to Hampton Cove. This mainly was exacerbated both by rainfall rates and enhanced runoff processes due to terrain (Monte Sano Mountain). Numerous roads were closed as well, with one river gage (DUGA1) measuring nearly 4 of rainfall in one hour.
