A thunderstorm that blew through Rome and Floyd County on Wednesday afternoon was brief but it caused downed trees and power lines and left people stranded in elevators during the power outage.

Rome-Floyd County Fire Department firefighters had just left the Etowah riverbanks where they rescued two people when they received a call about people trapped in elevators in two of the high-rise apartment buildings off of North Fifth Avenue and in an elevator in an apartment building at 90 E. Second Ave., according to fire officials.

A tree that fell on a substation on Avenue A appeared to have caused the power outages, a Georgia Power spokeswoman said.

In all, about 520 people throughout Rome and Floyd County were without power at the height of the storm, said Lynn Wallace, a spokeswoman for Georgia Power.

Officials with Floyd County 911 Emergency Communications Center said trees were reported down throughout the county.

No injuries were reported as a result of the storm.

Shortly after the storm moved out of Floyd County severe thunderstorm warnings were issued in Gordon, Murray and Whitfield counties.

The storm did not damper the July 4 holiday as the fireworks at Ridge Ferry Park went off at dark as planned.
