I've never see such cooperation from citizens. Morning after many guys, thank goodness there's guys, they were already out clearing downed trees in roads with chain saws. There was heavy equipment everywhere used for larger trees and debris. They do this to make easier passage for the utility company field employees who worked night and day to bring back power. A time saver for them.
Much of the immediate volunteer work was also provided by business that remove trees.
After having been through a number of near-disasters (tornados and earthquakes - Wuhan flu doesn't even register, aside from the shredding of the constitution), you will find that the first week or so, and particularly the first few days, people will definitely rise to the occasion. Only after it is become routine to they start reacting to the tragedy.
Human beings are quite extraordinary, when they need to be.
I'm told tornadoes are extremely rare in this area of Tennessee.
There's no part of Tennessee that is immune to tornados. It's not Kansas or Oklahoma, but much higher incidence than a lot of other places. This is about the right time of the year for it in the KY/TN/Ohio Valley. The Super Outbreak (one of the series of hundreds of tornados over about a 8-12 hour period hit my town in Kentucky) was in early April 1974. Later, the likely spots tend to move north. OK/KS/NE,Texas Panhandle, almost any time.
It's not something you have to wait for in dread, you should generally be alert to it any afternoon it looks like thunderstorms, and they tend to overdo it on tornado watches, to the point you might start ignoring them.
