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 short-lived tornado touched down along Egypt Road near Vaughn Lane snapping a few trees. The tornado tracked north-northeast and intensified near Shady Grove Road where a single-wide manufactured home was destroyed. Near the intersection of Mountainboro Road and Carlisle Cut Off, a house was shifted off its foundation, but the house itself sustained only minor roof damage. A wood barn in a field was also heavily damaged. Just south of Lawson Gap Road, several trailers were damaged with one losing its roof and portion of its exterior walls. Trees were snapped or uprooted on the west side of Mountainboro Road. The tornado was at its peak intensity along Mountainboro Road between Shady Grove Road and Lawson Gap Road, with maximum winds between 90 and 100 mph. The tornado continued north, causing additional damage along Skyhaven Drive, where a two-story house lost a portion of its roof covering. Several trees were snapped or uprooted around this location as well. To the north, off Douglas Drive, a manufactured single-wide home lost most of its roof, its entire garage/car port and a good portion of one exterior wall. The tornado crossed U.S. Highway 431, snapping several trees near the intersection of Highway 205. Between Cox Gap Road and Gaines Street several large trees were snapped or uprooted and displayed a convergent path toward the center line of the tornado. The tornado crossed Sardis Road snapping a few trees near the intersection of Sardis Cut Off Road before lifting.

The wider storm

A large scale severe weather event began Saturday, April 26 and ended Wednesday, April 30th, producing several waves of severe weather from the Central Plains eastward through the Deep South, and across a significant portion of the eastern United States. Strong and violent tornadoes, very large hail, flash flooding, and damaging straight line winds accompanied this dynamic storm system. The most tornadoes occurred across the Deep South as the system moved into Mississippi and Alabama on Monday, April 28th. Supercell thunderstorms developed during the afternoon over eastern Mississippi and northwest Alabama in the warm sector well ahead of a cold front. The activity slowly spread east and southeast overnight, with this wave of severe storms ending early Tuesday morning. Storms redeveloped late Tuesday afternoon and moved into Central Alabama. A large area of rainfall across the northern Gulf Coast limited the amount of instability across the area, and storms remained below severe limits. The last wave of severe weather occurred early Wednesday morning across the south as an isolated storm produced large hail, as the system finally pulled east of the area.

Began near Rockledge (34.0896, -86.1550).
