Survey summary: Additional information from storm spotters suggest
the first touchdown occurred in northwest portion of The Acreage/
Loxahatchee and continued on the ground for about 3 miles before
lifting. Damage in The Acreage consisted mainly of snapped pine trees
and large branches, intensity EF-0. The track continued in the
Mirabella neighborhood of Palm Beach Gardens west of Florida Turnpike
between PGA Boulevard and Donald Ross Road, then followed a
discontinuous path ENE across Palm Beach Gardens to Juno Beach where
it moved offshore at the Juno Beach Pier.

EF-1 damage was concentrated mainly in the Mirabella neighborhood and
east of I-95 at The Benjamin School. A few homes had tiles removed in
Mirabella, causing broken windows from flying debris. At The Benjamin
School Upper Campus, a full set of metal bleachers was blown across
a football field for at least 50 yards, with some of the pieces of
the bleachers landing in an adjacent wooded area well over 100 yards
away. Debris from this location ended up as far away as Dwyer High
School about 500 yards east from the original location. At Dwyer High
School, the tornadic winds as well as flying debris broke windows,
damaged a softball field and caused a small hole in the ceiling
over a classroom in the school`s main building. Damage estimates at
Dwyer High School are in the $500,000 to $1 Million range.

Most of the remainder of the damage along the path was rated EF-0 and
consisted mainly of broken tree branches, uprooted trees and damage to
mobile homes in Juno Beach. The tornado moved offshore at the Juno Beach
Pier around 145 AM where an unconfirmed wind gust of 87 mph was recorded.
A piece of the railing at the pier was removed, likely from the winds
of the tornado.
