Recap: Irma’s actual impacts on the Tennessee Valley

The remnants of Hurricane Irma moved through the Southeast Monday and Tuesday, prompting a tropical storm watch turned warning for much of Alabama, including the Tennessee Valley.

While not unusual, the tropical storm watch/warnings for the area were not unprecedented. According to a Sunday night area forecast discussion published by the National Weather Service in Huntsville:

For the first time in a long time, portions of Northern Alabama and
Southern Middle TN are included in a Tropical Storm Watch. Generally
all counties along/E of I-65 (with the exception of Limestone County)
are included in this product, and the last time we issued one was
back in 2005 for both Hurricanes Dennis and Katrina. So while it`s
not the first time it`s ever happened, it`s still generally rare to
have such a product out this far inland.

In southern Tennessee, a wind advisory was issued ahead of Irma. NWS meteorologist Stephen Latimer explained the difference between the two alerts:

A tropical storm watch and warning are issued for an actual named tropical storm that is expected to impact an area. A wind advisory is mostly issued for gradient winds, but in this case the winds are associated with either a Tropical depression or remnants transitioning to extra tropical.‚Äč

Below is a recap of Irma’s impact to the region, including wind, rain, and local storm reports.
