A Storm 5 Alert has gone out for the greater Nashville area as a result of the severe storms and the consequent flooding this weekend. Between Friday and Saturday evening there were three rounds of storms which resulted in a Flash Flood Watch to be set until 4 a.m. on Sunday. Saturday the main threat was flooding from the storms, with many roads being closed as a result of creeks and rivers cresting. Multiple reports have been made not only about closed roads but also about creeks with rushing currents that are impassable. Officials have released a list of roads that have been barricaded but have also included a list of areas that they are monitoring. The forecast on Sunday includes showers, which might result in flash floods. These flash floods are highly likely due to the amount of saturation in the soil, which means it probably can not hold anymore.
The rain on Friday came with strong winds that added a tornado warning into the mix for parts of several counties. The winds caused fairly severe damage in the path of the storm in Shelbyville, the National Weather Service reported in that these were more specifically straight-line winds. Peak winds in the area at the time of Friday’s storm reported in with speeds between 65 and 70 miles per hour. The damage stretched about 50 yards. These winds caused the collapse of a motel roof. The second round of storms hit between 1 a.m. and 7 a.m. on Saturday with strong winds and rain passing through the middle of the state. The third and final round of storms hit between 1 p.m and 7 p.m. on Saturday.
The main concerns with these storms included flooding and downed trees. These were a main concern because of the saturated soil that resulted from the storm, as saturated soil not only allows for faster flooding but can also cause trees to uproot faster as they have nothing to cling to. There have also been warnings issued for tornadoes, and strong winds were a secondary concern after flooding. I bet that the roads which closed were either located at the bottom of a hill and were very flat, or near a stream or river. I would also like to include in this post the reminder that the Nashville PD put out, “turn around, don’t drown” because while it sounds funny it is actually really good advice considering that some of the streams were reported as having impassable rushing currents.
