With a tropical storm headed directly toward Tennessee, the area could get more than 2 inches of rain in just 24 to 36 hours.

With that much rain in that timeframe, creeks and rivers can quickly reach potentially dangerous flood levels.

Prepare by staying informed and knowing exactly where you fall on the flood plain.

Williamson County Flood Risks

The above map, which if you’d like to explore or take a closer look at, shows flood plains using a feature on the county’s geographic mapping system. The darker blue represents the area likely affected by a 100-year flood; the lighter blue areas represent the extent of a 500-year flood. 100-year flood means that for every hundred years, there is one flood that reaches as far as shown; in other words, each year you can expect a 1 percent chance of a flood that large. A 500-year flood means that in a given year carries a 0.2 percent chance of such a flood.

Stay Informed

To stay aware of any emergencies during severe weather, stay on top of communication channels used by your local police department.

“Any time the threat of severe weather exists, we urge people to tune in to local television news and the National Weather Service for the most timely, reliable information. A NOAA Weather Radio with S.A.M.E. technology should be in every Franklin home and business,” Lt. Charles Warner of the Franklin Police said.

“Traveling flooded roadways is extremely dangerous and must be avoided – period. Flooded streets should always be reported to the police so that areas of danger can be quickly blocked, monitored, and mitigated.”

Williamson County Emergency Services will coordinate any county-wide efforts and monitor the situation and act as needed.

The Last Flood

The floods that spread across much of middle and west Tennessee in 2010 were 1,000-year floods. It took less than two days of extremely heavy rain to flood practically every river and creek in the area, and ultimately the deluge led to 31 deaths and $2.3 billion of damage.
