According to the National Weather Service:
AT 254 PM EDT...TRAINED WEATHER SPOTTERS REPORTED A TORNADO. THIS TORNADO WAS ON THE GROUND IN CLEMSON...MOVING NORTHEAST AT 27 MPH.
The warning was (is) in effect till 330 PM EDT (another twenty minutes as I write this). I took the above snaps just outside our building and you can see the dark cloud, spinning slowly, but no hail and no actual funnel. The fellow who phoned in the above report says he saw a water spout on Lake Hartwell from the windows in our stairwell. It may have been out there—I was in the stairwell and heard him phone this in, but I didn't see anything myself. Hopefully it stayed away from our house, which is just beyond the lake, from my current perspective.
UPDATE: It turns out there was a tornado and it touched down just outside Fike, the building that houses our campus gym. It took out a rather large tree in the process; we drove by it later that afternoon and were amazed at the damage made to the tree (basically the tree was just twisted off—with a lot of force!).
