SURVEY SUMMARY:

This EF1 tornado began about 3 miles southeast of May, Texas.  It moved southeast,
then northeast and then turned back to the northwest and west, making a
complete loop. The tornado uprooted and snapped branches of many large Oak Trees.
The tornado tore off a roof of a mobile home, destroyed a chicken coop, damaged
outdoor lawn furniture, ripped off sheet metal of a barn and tossed it for over
100 yards. As the tornado continued to move west across County Road 478, it became
about a half mile wide as it damaged numerous trees.  At this point, based on
radar, the twister was at its strongest.
