The stadium asked everyone to get out and take shelter immediately.
Just before 7:30 p.m. concertgoers were allowed to return to their seats as the show planned to resume.
Saturday's concert lineup is Brandon Lay, Old Dominion, Thomas Rhett and Kenny Chesney.
Came to see Kenny Chesney at MetLife, and Mother Nature isn’t having it. Concert is in a weather delay. Thousands of people have been moved inside to the concourse. pic.twitter.com/cV31Xq7M7N— Ryan Field (@RyanFieldABC) August 18, 2018
This is the second time storms forced an evacuation during a major concert there.
A couple of weeks ago, there was an evacuation at the Beyonce and Jay-Z concert.
