This Hazardous Weather Outlook is for portions of Middle
Tennessee.

.DAY ONE...Today and Tonight.

Flash flooding may become an issue as several areas have already
received 2 to 4 inches of rain. An additional 1 to 3 inches is
possible today and tonight, and while there is low confidence on
the exact location of the new rain, training storms throughout the
day will increase the flooding risk generally for those west of
the Cumberland Plateau.

.DAYS TWO THROUGH SEVEN...Sunday through Friday.

Excessive rainfall in possible Sunday and Monday, generally west
of the Cumberland Plateau. This extra rain could exacerbate
flooding concerns both days. Rises on area rivers might also
become a problem by the start of next week.

.SPOTTER INFORMATION STATEMENT...

Spotter activation may become necessary for rainfall measurements
and flooding reports today and tomorrow.

Hydrologic Outlook
National Weather Service Nashville TN
213 AM CDT Sat Sep 22 2018

...Excessive Rainfall Possible over the Weekend...

A surface boundary has moved into Middle Tennessee and will become
stationary during the weekend. Several rounds of showers and
thunderstorms along this stationary boundary will offer the
potential for 1 to 3 inches of rain in areas generally west of the
Cumberland Plateau, with some areas seeing more than that by
Sunday evening.

Already, some areas in western Middle Tennessee have received
significant rainfall amounts owing to slow-moving thunderstorms.
More areas will likely be affected as this system interacts with
an unusually moist atmosphere.

Flash flood guidance is elevated due to the lack of recent
rainfall. This suggests most areas in Middle Tennessee can
tolerate the forecasted rain amounts. However, some areas will
likely see multiple rounds of slow-moving storms with high
rainfall rates, and flash flooding may occur in these areas.
