PARADISE — Authorities have confirmed that it was a tornado that blew through central Pennsylvania and caused a pavilion to collapse at a park, injuring 15 people and causing millions of dollars damage.

The EF-1 tornado touched down shortly after 8 p.m. Friday and over the next 10 minutes traveled about 16 miles from Fern Glen to Paradise in Lancaster County packing maximum winds of 100 to 110 mph, the National Weather Service said Sunday.

Officials said several dozen people attending a baseball game near Paradise sought shelter at the 40-foot by 40-foot pavilion, but high winds caused the structure to collapse. Police said 10 to 12 people were injured but the weather service put the injury total at 15. Authorities said most of the injuries were minor; one person had a broken bone. The tornado damage was sporadic and embedded within a larger area of straight-line wind damage,” weather observers said.

Officials said 50 structures were damaged.
