(CNN) — At least one person was killed and 16 others injured Saturday afternoon when a sports bar tent collapsed during a storm that swept through the St. Louis area, fire officials said.
Downtown St. Louis was under a tornado warning Saturday evening as storms continued to push through.
St. Louis Cardinals baseball fans had gathered after a victory over the Milwaukee Brewers at the bar, which had a tent set up in the rear, according to fire Capt. Dan Sutter.
High winds knocked down pieces of the tent, near Busch Stadium, officials said.
“We had live wires lying on the ground. We have severe injuries to quite a few people,” said St. Louis Fire Chief Dennis Jenkerson. “This gives us nightmares.”
The area had been under a severe thunderstorm watch, with a warning issued shortly before the incident.
“The wind speed when it hit that tent could have been 40 to 50 miles per hour, may have been stronger. It’s hard to tell,” said National Weather Service meteorologist Jim Kramper. “This cell blew up very quickly.”
A strong thunderstorm north of the city produced golf-ball-sized and larger hail, according to Kramper.
Portions of eastern Missouri and western Illinois were under tornado watches Saturday evening.
