Flash Flood Watch issued for Middle Tennessee; Heavy rainfall possible with Alberto
Subtropical Storm Alberto will make landfall on the Gulf Coast today and is expected to become a tropical depression as it approaches and moves across the mid state Tuesday into Tuesday night.
Storm total rainfall associated with Alberto is expected to range from around 1.0 inch across Upper Cumberland Region to around 2.0 inches across Nashville Metro Area to around 1.5 inches across TN River Valley Region. Most of this rainfall will occur Tuesday afternoon. These amounts are generally below expected flash flood guidance values. However, locations that have and are expected to experience brief heavy rainfall through tonight could experience runoff from brief heavy rainfall associated with Alberto.

Total rainfall amounts from around one inch to around two inches with locally higher amounts approaching three inches are possible. Some flash flooding is possible. In addition, you can expect rises to occur on area creeks and streams, and possibly along larger rivers as well.
A Flash Flood Watch means that conditions may develop that leadto flash flooding. Flash flooding is a very dangerous situation.
You should monitor later forecasts and be prepared to take action should Flash Flood Warnings be issued.
