...NWS Damage Surveys for Tornadoes on July 7th Amended...

.Update...Lowered peak wind speed at the Kings Bay Submarine 
Base RV Park to EF-1, 110 mph based on further review with 
meteorologists more experienced with these types of vehicles. 
The peak wind for the event is now reduced to 120 mph based 
on structural damage on E. Conyers St. in the City of 
St Marys, GA. 

.Overview...As Tropical Storm Elsa moved northward across 
the Florida Big Bend region and through southern Georgia, 
cyclic supercell thunderstorms developed, embedded in a
primary outer rain band on Elsa's east side. As these
supercells moved rapidly northward, damaging tornadoes 
touched down in south central Duval County and then over 
eastern Camden County. Both tornadoes produced significant
damage, with the Camden County tornado resulting in 
approximately 17 injuries at the Eagle Hammock RV Park near 
the U.S. Naval Submarine Base at Kings Bay, GA.

Survey Summary:

National Weather Service damage survey found that the tornado 
initially touched down along East St. Marys Street, or just north 
of the St. Marys River, where tree trunks were snapped. The survey 
found that the tornado then strengthened to EF-2 intensity, producing 
significant damage to residences along E. Conyers and Norris Streets in 
St. Marys before pivoting north-northwestward, producing EF-1 damage 
to homes and apartments along Point Peter Road. The tornado 
reached its maximum width at the Eagle Hammock RV Park, when tornado 
was at EF-1 intensity, with max sustained winds of 110 mph. There were 
multiple recreational vehicles flipped over, with two completely flipped 
upside down. One RV was flipped and blown about 200 yards into a lake 
north of the RV park. Several hardwood trees at the park were also
snapped. There was debris from the RVs scattered throughout the RV 
park area.
