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 is an extension of the Lawrence County EF-2 tornado that briefly crossed into Orange County before lifting. The tornado produced EF-1 level damage in Orange County, destroying two mobile homes. One mobile home rolled over onto a new vehicle where three occupants were unhurt. The car ended up inside the living room of the mobile home. The other mobile home took a direct hit, taking the roof off and blowing the walls out of half of the home. An occupant of the home was blown into the field with home debris, while leaving living room furniture in place. The resident received only minor injuries.

The wider storm

The combination of a moist and unseasonably warm air mass and an approaching low pressure system and cold front brought multiple rounds of severe weather to southern Indiana during the early morning hours on March 1. In the end, there were 5 tornadoes across southern Indiana, the strongest being an EF-2 that tracked through portions of Dubois County. In addition to the tornadoes, there were several areas of intense straight-line winds estimated up to 100 mph in places. The impacts included numerous areas of structural damage and downed trees. The widespread heavy rain brought the Muscatatuck River at Deputy into minor flood.

Began near Leipsic (38.6884, -86.3300).
