The path drawn at its surveyed width of 200 yards (0.11 mi) — zoom in and the swath grows to true scale. Other tornadoes recorded nearby that day are shown faint.

What EF0 means. On the Enhanced Fujita scale, EF0 is light damage: shingles and siding peeled, gutters torn, branches broken, consistent with estimated gusts of 65–85 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 far northwest Calhoun County and determined that it was consistent with an EF0 tornado, with maximum sustained winds near 65 mph.

The same supercell that produced a tornado in the Friendship community of St. Clair County produced another tornado in extreme northwest Calhoun County, just north of the town of Ohatchee. The tornado touched down along Greensport Road just west of Cochran Springs Road. It paralled Greensport Road for approximately three-quarters of a mile, crossed Dodd Gap Rd and lifted between Dodd Gap Road and Greensport Road. Damage mainly consisted of snapped and uprooted trees, but one residence sustained very minor shingle damage.

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 Grayton (33.8453, -86.0295).
