The Tornado Chronicles: Corning, AR Tornado of 9-1-12...

One of the tornadoes spawned by the remnants of Hurricane Isaac was rated EF-2 intensity, which is relatively strong for the type.  The above photo near Corning, Arkansas was taken by Robert Rowland and posted on twitter.

According to the post storm survey completed by the National Weather Service (NWS), the tornado touched down about 1 mile Southwest of the Corning airport and tracked toward the Northeast for approximately 2.5 miles before lifting about 1.5 miles Northeast of the Corning airport.  The maximum path width was 75 yards.

There was significant damage done to hangars at the airport:

The damage in the 2nd photo, which shows the near complete failure of a hangar at the North end of the airport, is primarily responsible for the EF-2 intensity rating.  A 930 pound piece of equipment was also moved nearly one-quarter of a mile away from the building in which it had been stored.

Fortunately the tornado took the path that it did, for had it touched down just a few miles to the East (see map below) it would have tracked through the town of Corning, potentially causing much more damage and injuries.

While the Corning area tornado followed the M.O. of a tropical cyclone induced tornado with respect to its short lifetime, it actually performed in the upper end of the spectrum with respect to intensity.  Most tornadoes generated by tropical cyclones and their remnants rate EF-0 to low end EF-1 intensity.
