Tornado warning issued for much of St. Louis Wind hits sports bar tent near Busch Stadium in St. Louis Fire officials say one person was killed, at least 16 hurt (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 gathered after a victory over the Milwaukee Brewers at Kilroy's, which had a tent set up in the rear, according to fire Capt. Dan Sutter. The bar is south of Busch Stadium. High winds knocked down pieces of the tent, officials said. 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. CNN's Greg Morrison, Jacqui Jeras and Phil Gast contributed to this report.
