13 damage points were recorded along this path by NWS TAE, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF1. The highest wind the damage implies is 110 mph.

• surrounding DIs undamaged.
• a few other trees snapped or down at start location.
• solid EF1. swath of pines snapped. fall pattern supports convergent pattern into a center circulation. unsure if damage is solid between this and start point.
• 100-150 yd wide swath. tree fall consistent with tornado.

A strong long wave trough was centered over the mid Mississippi Valley extending south to the Gulf coast with several shortwaves rotating around it. During the April 29-30 time period, a strong MCS developed along the Gulf coast and trained across the area, producing extremely heavy rainfall rates and amounts on top of what had already been a very wet month with additional rainfall amounts of 6 to 10 inches common across the area. This led to serious flooding across portions of the Florida panhandle with several million dollars in damage reported, mainly to roads. However, several structures were also impacted by flood waters, especially in Walton county, and a FEMA disaster declaration was obtained across the area.

This tornado touched down a half mile or so east of Highway 77 south of Graceville. Damage was mostly to trees, but several homes were also damaged. One was severely damaged when a large oak tree toppled onto it. Damage to trees and to one home east of Highway 77 was consistent with EF1 damage with peak winds around 110 mph. This tornado also exhibited a debris signature on dual-pol radar. Monetary damage was estimated.

A second tornado was confirmed in Jackson county starting along Highway 231 southeast of Campbellton with a few trees blown over and snapped. There was evidence of sporadic damage to trees to the north-northeast. The second, and more significant area of damage of damage was to a grove of pine trees east of Campbellton along Highway 2. There was clear evidence of a tornado at this location consistent with higher end EF1 damage. There was no evidence of damage very far to the northeast of this road. Peak winds were estimated to be around 110 mph, and this tornado produced a debris signature on dual-pol radar. Monetary damage was estimated.

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.
