Survey Summary:
A tornado touched down in the vicinity of Crowder Chapel and
Hinote Roads near the Shoal River. Several large trees were
snapped or uprooted in this area. The tornado then moved east
northeast snapping and uprooting several more trees along its
path. One property on County Highway 1084 sustained roof damage
to the primary residence, a well-built single family home. A
large metal building system on the property had large garage
doors blown in with subsequent uplift and removal of a
substantial portion of the roof. A small garage was also
destroyed. A bit further down the highway, another metal building
system had a portion of its roof rolled back. The tornado lifted
near County Highway 83 just south of Glendale. Damage was
consistent with an EF1 tornado with maximum estimated winds
around 95 mph.

.Laguna Beach Tornado...

Rating:                 EF2
Estimated Peak Wind:    125 mph
Path Length /statute/:  0.4505 miles

Injuries:               0

Start Date:             04/10/2021
Start Time:             08:42 AM CDT
Start Location:         2 WNW Gulf Resort Beach /  / FL

End Lat/Lon:            30.2346 / -85.9102

Survey Summary:
A waterspout came ashore near Laguna Beach and heavily damaged a
convenience store and a home. This was where the heaviest damage
occurred. The convenience store roof was completely torn off of
the building and lofted into a nearby house. The concrete block
exterior walls were also partially collapsed. It appeared that at
least some effort had been made to strap the roof to the walls of
the structure, making this damage reflective of an EF-2 rating
with maximum winds of 125 mph. Behind the convenience store, a
house was heavily damaged with portions of the roof missing, but
most of the damage to this home came from the roof of the store
landing on it. A projectile piece of wood was observed lodged in
the side of another nearby home. Several surrounding homes also
had minor roof damage, glass breakage, and fencing damaged or torn
down. Another home had a carport structure completely collapsed
and a wooden shed blown over and rolled into a fence.

.Lynn Haven Tornado...

Rating:                 EF1
Estimated Peak Wind:    105 mph
Path Length /statute/:  0.2486 miles
Path Width /maximum/:   30.0 yards
Fatalities:             0
Injuries:               0

Start Date:             04/10/2021
Start Time:             09:00 AM CDT
Start Location:         Lynn Haven / Bay County / FL
Start Lat/Lon:          30.2353 / -85.6503

End Date:               04/10/2021
End Time:               09:01 AM CDT
End Location:           Lynn Haven / Bay County / FL
End Lat/Lon:            30.2348 / -85.6462

Survey Summary:
Damage was widespread across Lynn Haven Parkway as a line of
storms pushed through the area. Despite there being damage well
south of the estimated path, much of this damage is estimated to
come from straight line winds associated with the squall line.
Roof damage to Haney Technical Center and a blown over semi on the
Parkway were observed and consistent with these straight line
winds. Damage just south of 14th street near the estimated path,
including the greatest damage to Grease Pro Express, was found to
be consistent with that of a strong EF-1 tornado. At that
location, the roof was lifted upwards and displaced/rotated about
30 degrees. Similar, but less intense, was found at homes near
the Grease Pro Express. Outside of this location, minor roof
damage was observed at many locations, but none of this damage was
consistent with a tornado and the estimated duration of the
tornado was very brief, 3 minutes at most. Maximum winds were
estimated to be 105 mph.

EF Scale: The Enhanced Fujita Scale classifies tornadoes into the
following categories:

EF0...Weak......65 to 85 mph
EF1...Weak......86 to 110 mph
EF2...Strong....111 to 135 mph
EF3...Strong....136 to 165 mph
EF4...Violent...166 to 200 mph
EF5...Violent...>200 mph
