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

National Weather Service meteorologists surveyed damage in Perry County and determined that it was consistent with an EF1 tornado, with maximum sustained winds near 90 mph.

The same supercell that produced the tornado near Heiberger produced another tornado in northeast Perry County. The tornado touched down west of AL Highway 219 near the intersection of Fire Tower Road and Sherman Huey Road. This location is about 10 miles south southwest of Centreville. Several trees were snapped off and many trees had broken branches. The tornado tracked northeast and crossed Highway 219 near the intersection of Star Circle. This is where the most concentrated damage occurred. Numerous trees were snapped off and uprooted and some power poles were downed. Several outbuildings were damaged here mainly due to fallen trees. The tornado continued east northeast and crossed Foster Road, Whitetail Road, Buck Road, and Mill Creek Road and then crossed into Chilton County. Hundreds of trees were snapped off or uprooted.

The wider storm

A widespread severe weather event occurred across central Alabama aduring the afternoon and evening hours on Thursday, March 14th. The event began in the northwest counties and spread eastward all the way to the Georgia state line. A strong low level jet of 40-50 knots, combined with moderate instability (1000-1500 J/kg) and 0-6km bulk shear of 55-50 knots, produced an atmosphere favorable for severe thunderstorms and supercells.

Began near Bethlehem (32.7966, -87.1707).
