3 touchdowns in Bradley County. Sitting in the basement watching the tornado pass by on radar when this popped up and it got a little louder outside. Saw the report today that the tornado occluded and popped a little more damage. Ya'll, I grew up in central Illinois and never had tornadoes this close, and now in less than 10 years here there are so many!

NEW Confirmed Tornado in Dorchester County, and UPDATED Colleton County Tornado Track....

.Walterboro, SC...Updated to extend path eastward...

Start Location...4 SW Walterboro in Colleton County SC
End Location...3 WSW Norman Landing in Colleton County SC

Estimated Time...06:47 AM EDT
Maximum EF-Scale Rating...EF1

Maximum Path Width...500.0 yards
Path Length...17.4 miles
Beginning Lat/Lon...32.8791 / -80.7305
Ending Lat/Lon...32.9784 / -80.456
* Fatalities...1

...Summary...
The tornado formed near Route 63 about a mile east of the West
Walterboro tornado. This tornado grew in size as it tracked through
Walterboro and then tracked northeastward through the Low Country
Regional Airport and then further northeast with a preliminary
length of about 8 miles. Further investigation needs to be done to
determine if the path continued farther to the northeast and if so
how far. This tornado produced extensive tree damage along the path
across northwestern portions of Walterboro with many hundreds of
trees snapped off or uprooted. Trees falling on houses or the wind
associated with the tornado produced mainly minor damage to hundreds
of residences and some businesses.

Inflow winds into the tornado produced significant tree and some
structural damage across the central and southeastern portions of
Walterboro. In this area a large pine tree fell through a section of
a home killing a person and injuring another.

At the Low Country Regional Airport, winds associated with the
tornado or winds flowing into the tornado damaged or destroyed most
hangers and damaged or destroyed nearly two dozen aircraft.

The tornado continued east-northeastward, sporadically touching down
just north of Route 17-A, between Sidneys Road to Red Oak Road, just
northeast of Cottageville. The damage was mainly snapping and
uprooting of trees.

Finally back online... Storm was damaging here in Fort Oglethorpe Ga.... I have roof damage and my backyard looked like a war-zone. Loss of 2 vehicles but, everyone is safe including family that sheltered in our home through the storm. Also, the data needs to be updated. Northwest Georgia Storm Spotters confirmed Chickamauga - Fort Oglethorpe Ga. experienced a EF-1 Tornado! The path of the the Hamilton & Bradley county tornado started in Chickamauga Ga.. Here's the official report.

Here is the official report for the tornado that began and or around Chickamauga and ended and Bradley County. This narrative was provided by the National Weather Service in Peachtree City. --Sheldon

According to the National Weather Service, the April 12 tornado that struck Battlefield Parkway in Fort Oglethorpe started off as a weak twister when it first touched down near the Chickamauga Battlefield Visitor Center. By the time it reached Battlefield Parkway it had strengthened to a 106-mph (EF-1) tornado.
Here’s the National Weather Service’s assessment of the tornado, which crossed the state line into Tennessee, where it strengthened, in some spots, to an EF-3 tornado with 145-mph winds.
Catoosa County, Ga./Hamilton County, Tenn. tornado ...

The weak tornado (initially) was embedded within very strong thunderstorm winds (QLCS) that was tracking quickly east-northeast. Ground surveys and radar data suggest it touched down on the south side of Fort Oglethorpe, near the Chickamauga Battlefield Visitor Center, snapping several trees near the intersection of Post Road and Lafayette Road. The tornado strengthened quickly as it approached the industrial area of town, along Battlefield Parkway (Ga. Highway 2) with several businesses sustaining structural damage, including a metal building structure (MBS) along Howard Drive completely losing an exterior (side) wall and part of its roof. It was in this area that a weather station at the Fort Oglethorpe Public Works Department measured an unconfirmed wind gust of 106 MPH (EF-1winds). The tornado then skipped to the northeast, snapping or uprooting small areas of trees with a few homes sustaining mainly roof/siding damage, from Park Forrest Drive to several side streets off of Ga. Highway 146 (Cloud Springs Road), to Carrol and Karen Drive. The tornado crossed I-75 along Scruggs Road, then crossed the Tennessee/Georgia state-line somewhere between Scruggs Road and US Highway 41 (Ringgold Road in Tennessee).

As the tornado crossed the state line, it quickly moved across the Harris Hills area where some trees were uprooted. It then continued towards East Brainerd Road and Stratman Circle where an auto parts store was completely leveled and nearby structures had significant roof damage done. The tornado then struck the end of a large shopping building where a restaurant was located. The restaurant facade was destroyed and the roof was peeled back. This is where the tornado picked up strength and was near its peak intensity. It continued northeast into the Drake Forest neighborhood where extensive structure, roof, and tree damage was noted. There were likely pockets of EF-3 damage here, as well. The tornado damage path really widened as it moved northeast into the Holly Hills neighborhood. This was likely the widest part of the tornado. Nearly as far as you could see to the southeast, tree trunks were snapped and significant home damage was noted. Some areas were blocked by tree debris and fallen power poles as well as large clean up machinery which limited easy access to some areas. Additional damage was found in Ooltewah near the Summit Softball Complex and particularly the significant roof damage to several units/buildings of the Integra Hills Preserve Apartments. The tornado weakened as it crossed South Lee Highway and eventually dissipated in southwestern Bradley County.

Below is the final path.

...Summary...
The tornado began in the Fairlawn Subdivision, just east of Moncks Corner.

Several homes had significant damage along Old Fort Road and Dennis Blvd.

There was a home at the east end of Dennis Blvd that had significant
enough damage to justify an EF3 rating. There was also extensive snapping
and uprooting of trees, as well as vehicle and trailer damage in the area.

The tornado moved east-southeast, generally down Dennis Blvd, eastward
across the west branch of the Cooper River, and then east-northeastward
across SC-402 and Cane Gully Road.

At this location, a mobile home was
completely destroyed, several other homes and structures sustained
significant damage.

The tornado continued east-northeastward snapping
and uprooting trees, with significant damage to at least one home off of
Myrtle Lane, and minor roof and siding damage to approximately four
additional homes just south of Bullhead Road.

The tornado then dissipated
near the intersection of Myrtle Lane and Wright Road.

This tornado was
part of a family of tornadoes that began more than 100 miles
to the southwest, in Screven County, GA.
