What EF1 means. On the Enhanced Fujita scale, EF1 is moderate damage: roofs badly stripped, mobile homes pushed off foundations or overturned, windows broken, consistent with estimated gusts of 86–110 mph. The rating comes from a survey of the worst damage after the storm, not from a wind measurement, so it says as much about what the tornado hit as about how strong it was.

What the National Weather Service wrote

This tornado developed in eastern Carroll County, Indiana, roughly four miles east-southeast of Burrows (see Storm Data for Indiana, Central) and moved into Cass County. The tornado initially was over open fields with its first impact at a residence where the western half of the roof was ripped off and the eastern half picked up and then dropped back down. Two residents were attempting to take shelter when the tornado hit. A gentleman suffered minor injuries (indirect) falling down a stairway into a basement seeking shelter. The tornado continued east-southeast over mainly open field again until it encountered a more populated area of structures along E County Road 900 S, east of S County Road 300 E. Several trees were damaged or uprooted in the area with the western half of a business being destroyed by the circulation. The circulation moved on to strike and roll a mobile home, destroying it (DI: SWMH DOD: 7). The second injury (direct) in the area occurred here where the resident was rolled with the mobile home. The female resident escaped with minor injuries. The circulation continued on causing some structure and tree damage before dissipating. The maximum width is estimated at 150 yards with a maximum wind speed estimated around 100 mph.

The wider storm

A supercell developed ahead of a cold front in Illinois and tracked east-southeast through Benton county into White county. This storm produced three tornadoes across Indiana, an EF0 in Eastern White County (which moved into Carroll County), an EF1 which started in eastern Carroll County and moved into Cass County, and a third, a stronger EF3 which formed near the Grissom Air Force base in Cass County and moved rapidly east into Miami County. Despite the tornadoes occurring during the overnight hours, no fatalities occurred.

Began near Deacon (40.6447, -86.3736).
