EF1 tornado, Devon Park to Shideler, Indiana, April 2, 2025

1. EF065 to 85 mph

   Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.

2. EF186 to 110 mphthis tornado

   Moderate damage. Roofs badly stripped, mobile homes overturned or badly damaged, exterior doors lost, windows broken.

3. EF2111 to 135 mph

   Considerable damage. Roofs torn off well-built houses, frame homes shifted on their foundations, mobile homes destroyed, large trees snapped or uprooted, cars lifted off the ground.

4. EF3136 to 165 mph

   Severe damage. Whole stories of well-built houses destroyed, large buildings badly damaged, trains overturned, trees debarked, heavy cars lifted and thrown.

5. EF4166 to 200 mph

   Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.

6. EF5over 200 mph

   Incredible damage. Strong frame houses swept off their foundations, car-sized missiles thrown more than 100 meters, steel-reinforced concrete badly damaged, high-rise buildings deformed.

7. Unrated

   The survey recorded a tornado but could not put a number on it, most often because it crossed open country and damaged nothing a rating can be read from.

40 damage points were recorded along this path by NWS IND and NWS IWX, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF2. The highest wind the damage implies is 132 mph.

• Roof damage to swine barn and egg laying facility 6650 W and 6602 W 900 S Ridgeville. These addresses are on the same farm.
• Nearby house has shingles lifted. 100yds away a few large tree limbs down and some debris into a small barn.
• Large trees snapped pointing in a NE direction. No definitive indication that this is tornadic damage.
• Nearby house had siding that looked to be sucked out from the wall. Anchoring of structure isn’t the best. Because of the anchoring, didn't feel comfortable going with a total loss of strcuture, but did nudge winds up a touch.

A strong low pressure system generated a line of strong to severe thunderstorms that started in Illinois and moved across central Indiana. Multiple severe storms were embedded within the line and some of these produced tornadoes. Eleven tornadoes impacted central Indiana, ten of which occurred along an overall west-southwest to east-northeast area from north of Terre Haute to north of Muncie. Four of these events, from Hendricks County to Delaware County, were secondary tornadoes that tracked parallel to longer duration tornadoes. Three tornadoes combined to impact western and northern portions of the Indianapolis Metro area, including an EF2 in Hendricks County that caused the episode's only injury. In addition to the tornadoes widespread wind damage occurred with gusts over 80+ mph reported.

This tenth tornado to impact central Indiana was the last of five tornadoes spawned within Madison County and Delaware County, and the last of three secondary tornadoes to track within these two counties, tracking to the south of the main tornado. The tornado tracked between the Anthony area and the Delaware County Airport, approaching the Shideier community before ending. Sporadic damage along the track indicates the circulation was not continually on the ground as the tornado was likely embedded within the parent storm's rear flank downdraft. The tornado was strongest at its onset where it destroyed a barn by collapsing its walls, and at the track's end where it completely destroyed a farm outbuilding. Peak wind gusts were 100 mph.

15 minutes of warning. NWS IND issued a tornado warning for this county at 01:49 UTC, 15 minutes before the tornado touched down, in force until 02:15 UTC.

The county was under a tornado watch, issued at 01:16 UTC and running to 04:17 UTC.

Lead time is measured from the issue of the warning in force to the touchdown time in the database, both of which were recorded to the minute by different people.

The Storm Prediction Center had this point in a Moderate Risk, with a 0.15 chance of a tornado within 25 miles, in the hatched area where significant tornadoes were expected. The outlook in force was issued at 00:55 UTC.

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
