A closer look at the anticyclonic tornado track
Most tornadoes spin counter-clockwise, but during Monday's tornado outbreak, one tornado was spinning clockwise or backwards.

An anticyclonic twister developed about 6 miles north-northwest of Sulphur and moved northeast. The tornado has been rated as an EF1 tornado with winds up to 110 mph.
The tornado was likely wrapped in precipitation and not very visible. At the same time, a larger EF-3 tornado was on the ground, moving to the east, about 6 miles to the west of the anticyclonic tornado. One could even consider this rare tornado as it satellite tornado to moved around the larger tornadic circulation.
