The path drawn at its surveyed width of 50 yards (0.03 mi) — zoom in and the swath grows to true scale. Other tornadoes recorded nearby that day are shown faint.

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

A National Weather Service ground storm survey indicated a tornado path of approximately three quarters of a mile long and 50 yards wide in the vicinity of School Road and Highway 40. Seven homes were damaged, one mobile home was destroyed, and one trailer heavily damaged. One minor injury was reported. Several large trees were uprooted and broken off. The maximum estimated wind speeds associated with this tornado were in the 100 to 110 mph range.

The wider storm

Several episodes of widespread severe weather and heavy rainfall occurred from March 26th through the 28th as a series of strong upper air disturbances impacted the central gulf region as a meandering and nearly stationary frontal boundary drifted back and forth across the area.

Began near Independence (30.6378, -90.4949).
