National Weather Service storm damage survey teams investigated two areas of the more significant damage that occurred during the severe thunderstorms of Tuesday, August 4, 2009.  The teams looked at damage in Brown and Morgan Counties.

A team found that widespread straight-line wind damage occurred over northern Brown County, downing hundreds of trees.  Some of the most severe damage occurred east of Beanblossom and west of Fruitdale.  The damage indicates winds exceeded 60 mph over a large portion of northern Brown County.

At Eminence in Morgan County, a representative from the National Weather Service classified the damage to be from a weak tornado.  The damage began on the west side of Back Street where corn stalks were pressed down and pointing towards the east-northeast.  The damage continued eastward across the street where a tied-down, single-wide mobile home was flipped over and destroyed.  More damage was found across State Road 42 where much of a large tree was downed and another mobile home was damaged and unliveable.  The track continued east where a home on N. Forest St. was destroyed as its roof was totally lifted and spread downstream about 100 yards.  A garage located just behind this house had its roof collapsed and debris located just behind it.

Winds were estimated near 105 mph placing the damage as EF1 on the Enhance Fujita Scale.
