12 damage points were recorded along this path by NWS BMX and NWS JAN, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF1. The highest wind the damage implies is 93 mph.

• Small trees uprooted, small trees snapped
• Portion of an irrigation pivot flipped
• Video taken on a farm property off Jack Spann Rd of the tornado developing over an open field and moving northeastward

A volatile atmosphere was in place for the second time in two weeks, with potential for significant severe weather across portions of the Southeast United States. Vigorous wind shear as well as ample instability would combine to generate thunderstorms that had the potential for violent severe weather. Storms developed during the afternoon, bringing damaging winds and flash flooding to the region. However, the most significant severe weather would occur across the state line into Alabama.

A potent storm system affected Central Alabama on Thursday, March 25th. A highly-sheared environment combined with increasing instability produced numerous tornadic thunderstorms. Severe parameters were supportive of significant and long-track supercells, prompting the issuance of a rare High Risk Convective Outlook from the Storm Prediction Center for portions of Central Alabama.||A total of 10 tornado tracks were surveyed in Central Alabama. This included 4 EF3 tornadoes, 3 EF2 tornadoes, and 3 EF1 tornadoes. Damage was significant along the paths of the most intense tornadoes and, unfortunately, injuries and fatalities occurred. |Some storms were cyclic, meaning multiple tornadoes were produced by the same storm. The most impressive tornado of the event was the long-track tornado that traveled nearly 80 miles from Hale County to Shelby County. This ranked as the seventh longest single tornado track in the state of Alabama.

A tornado began in an open field south of Jack Spann Road, where it was observed and videoed as it developed and moved northeastward. The tornado continued into Pickens County, Alabama where it produced EF-1 damage. No damage was observed in Mississippi.

National Weather Service meteorologists surveyed damage in southwest Pickens County and determined that it was consistent with an EF1 tornado, with maximum winds near 90 mph.||This tornado originated in Noxubee County, Mississippi and crossed the state line southwest of the intersection of Highway 17 and Highway 32.

7 minutes of warning. NWS JAN issued a tornado warning for this county at 18:28 UTC, 7 minutes before the tornado touched down, in force until 18:45 UTC.

The county was under a tornado watch, issued at 16:37 UTC and running to 01:00 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 High Risk, with a 0.30 chance of a tornado within 25 miles, in the hatched area where significant tornadoes were expected. The outlook in force was issued at 16:29 UTC.

19 more were confirmed in the United States that day.

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.
