UPDATE: NWS confirms 9 tornadoes touched down during Tuesday's storms
UPDATE: The National Weather Service confirms nine tornadoes touched down in Alabama and Tennessee on Tuesday.
A team from the NWS's Nashville office was in Grundy County on Wednesday to survey storm damage from Tuesday morning.
It did not take long for them to declare a tornado caused the damage in the community of Pelham in Grundy County.
"In this case when you have trees uprooted, trees snapped, we know that at least takes 90 mph winds. So that equals an EF-1 tornado to cause that kind of damage,” said Krissy Hurley, Warning Coordination Meteorologist for NWS Nashville.
As they assessed more damage, they upgraded the strength in Grundy County to an EF-2 tornado with 115 mph winds.
"And the way that we get an EF-1, EF-0 is by looking at the damage, and we are able to determine what kind of wind speed causes that kind of damage typically speaking,” explained Hurley.
Grundy County had snapped trees, downed power lines, and damage to at least 16 structures.
Before starting the damage survey, Dennis Jones, Emergency Management Agency Director for Grundy County said, "I'm not positive, but I think when we are done with this that we'll see more than 16 structures, and most of these structures are houses that people live in."
There were two homes destroyed by the tornado but no known damage to businesses.
Crews from Grundy County's sheriff's, fire, and emergency management departments were out assessing the damage too, so they can report to Tennessee and federal officials. They also want to know how to help those affected by the storm.
"We've got a lot of volunteers reaching out to us. So, they don't know where to go and being able to help in whatever way they can to those individuals that do have damage on their property,” said Jones.
The community fire departments have already delivered food and water to those in need.
To make sure that all storm damage is documented, Grundy County officials are requesting that people send their address and damage photos to the Grundy County EMA Facebook page. You can also call dispatch at 931-924-2079 and give them your name and number for it to be forwarded to EMA director Dennis Jones.

PREVIOUS STORY: The National Weather Service has confirmed that an EF-2 tornado did touch down in Grundy County Tuesday morning.
The NWS says that while their survey is still not yet complete, for Coffee/Grundy counties, their preliminary data was able to verify the winds which reached a maximum of at least 115 mph.
The survey crews also said that they can safely say that the damage matches up with the storm damage in Franklin County, as well as the continuing damage in nearby Sequatchie and Bledsoe counties.
This would indicate that the damage would all be from the same storm, according to the NWS teams.
