Survey Summary:

The National Weather Service in Louisville confirmed an

EF0 tornado in Perry Crossings (near Sellersburg) in Central

Clark County Indiana.  The tornado touched down in a field just

west of Columbus Mann Road and Pinta Place.  Video photography

and eye witnesses saw 2 small tornado funnels from the supercell.

The first damage point was to three homes on Pinta Place. The

homes had shingle and roofing material loss, along with torn

gutters and awning damage. A couple of Bradford pear trees were

displaced to the north. Wind speeds were between 80 and 85 mph

with a width of 60 yards.



A tornado appeared to lift over a small lake before touching down

again at the intersection of Lumberfield Lane and New Perry Lane.

There was damage to 3 homes with shingle and roofing material 

loss. One home in particular had insulation and mud splatter 

thrown around all 4 sides of the house. Witnesses saw 2 small 

funnels and many had their ears popping. Wind speeds were 85 mph 

with a width of 60 yards. Corn stalks from the original touch down

point were thrown to this location.



Just before the house on Lumberfield, a wooden fence was

pulled apart and knocked over. Either a board from that fence or

one from a loosely connected outbuilding was thrown through the 

wall of the house near the bathroom window. The tornado lifted 

just beyond the house on the east side of Lumberfield lane, but 

debris from the houses landed into homes on Meriwether Drive. This

included shingles, particle board and one impressive 2x4 

impalement into the side of the house about 9 feet off the ground.



A tornado warning was issued at 9:15 PM EDT and touched down at 

9:23 PM EDT resulting in 8 minutes of lead time. The National 

Weather Service would like to thank Clark County Emergency Manager

Gavan Hebner for is assistance with this survey.
