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 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.

The wider storm

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.

Began near Jacobs (30.8788, -85.3641).
