November 15, 2005 Tornadoes

Four tornadoes struck the state on this date in 2005.  Two of them were rated F3 and produced over 30 injuries but fortunately no fatalities.

The first F3 tornado touched down in Daviess county near Washington and proceeded northeast for 12 miles, lifting at Crane Naval Base in Martin County. The tornado was up to 1/4 mile wide at times. The worst damage occurred 4 miles northeast of Montgomery. Despite the amount of damage, only one of the 31 reported injuries was considered serious.  The tornado was only on the ground for 2 miles in Martin County, and was significantly weaker and smaller.

An F1 tornado touched down briefly in northern Lawrence county, damaging two homes. This tornado came from the same supercell that spawned a F3 tornado in Daviess and Martin counties.  The tornado had a path length of 0.2 miles.

The third tornado, F3, touched down in northern Bartholomew county and continued into southeast Shelby county, where it would do the majority of its damage. No one was killed by this powerful tornado, despite areas of severe damage, and only one minor injury was reported. A resident sustained an ankle injury when moving quickly down into his basement with his family to take cover. The worst damage along the tornado's path took place along and near Vandalia Road just east of the town of Geneva, where a large hog farm was severely damaged, and an old farm house was blown off its foundation. The structural integrity of the destroyed home was insufficient to justify a violent rating. Around 25 properties were damaged in this largely rural area, with six declared total losses.
 
The fourth and final tornado touched down in Grant county southwest of the intersection of county roads 200 north and 600 east, traveled northeast and lifted near the intersection of county roads 400 north and 800 east. Damage was confined to a house suffering roof damage, several trees and power lines and grain elevator augers being overturned. The tornado crossed Interstate 69, just north of mile marker 66, which resulted in a semi truck being blown off the highway.  This tornado was rated F1 and had a path length of 3 miles.

November 6, 2005 Evansville Tornado

Although there was only one tornado on this date, it was a big one.  This is an ultimate example a tornado hitting a bad place at a bad time - namely, a mobile home park in the wee hours of the morning. This tornado killed 24, injured over 230, and was on the ground for 41 miles as it tracked through Vanderburgh, Warrick, and Spencer counties.  It was deemed a high end F3 and was about a quarter mile wide. This was the deadliest tornado to hit the state in decades.

Here is a picture of the tornado taken by a hospital security camera:

Detailed Year By Year Tornado Statistics

Here is a table showing various tornado statistics for every year since 1950.
Significant tornadoes/days are down since the 1960's, possibly due to less favorable meteorological setups but probably at least partially due to more rigorous surveys.

Record keeping was still pretty poor in the early 1950's which may explain the very low numbers in those years.
