NASHVILLE, Tenn. − Thousands of Tennessee residents remained without power Monday after the National Weather Service officially confirmed two tornadoes tore through over the weekend, flattening homes and businesses, and killing at least six people including a toddler.
The Nashville suburbs of Hendersonville, Gallatin and Madison − where three people died − were slammed by a tornado with peak winds of 125 mph, the weather service reported late Sunday.
Northwest in Clarksville, another tornado with peak winds of 150 mph razed homes and left three others dead and dozens injured. Although the complete storm path could take days to determine, survey teams determined the Clarksville twister was on the ground for more than an hour and tracked for 43 miles through Tennessee into southern Kentucky, Josh Barnwell, a meteorologist with the NWS in Nashville told USA TODAY.

Potentially 13 tornadoes over an 8-hour period
Emergency response officials preliminarily counted 13 tornadoes impacted the state, Barnwell said, though they were continuing to confirm the total number on Monday.
The severe weather outbreak that began early Saturday afternoon and ended about 10 p.m. may be the deadliest December tornado event on record for Middle Tennessee, the NWS reported. The region previously recorded a total of eight tornado deaths, spanning decades of tornado incidents, in December.
In less than an 8-hour period, dozens of people were injured, cars flipped on I-65, trees buckled, and roofs were blown off buildings as shoppers hunkered down in store basements Saturday for what the NWS preliminarily determined was a string of tornadoes.
The first tornado warning was issued at 1:22 p.m. in Stewart County and Montgomery County, where Clarksville is located, some 50 miles northwest of downtown Nashville.
In all, the weather service issued 34 severe weather warnings − 20 which were tornado warnings, Barnwell said. The last warning was issued at 8:30 p.m. near the Alabama border in Coffee County, Tennessee.
"We have not heard of any damage from that area yet," said Barnwell, who added the NWS plans to send survey teams to Coffee County this week.
Tornado ratings confirmed as EF-3, EF-2
On Sunday the NWS confirmed an EF-3 tornado with winds that reached 150 mph touched down in Clarksville.
The tornado that touched down in Madison, Hendersonville and Gallatin received a preliminary rating of EF-2, with winds of 125 mph.

The weather in Middle Tennessee this week is going to be mercifully uneventful. Temperatures are going to stay on the cool side today, but we'll warm up some tomorrow and then temperatures are going to level off for the foreseeable future. It is unclear when it will rain again. pic.twitter.com/1XippDX1D5
