Storm-driven floodwaters inundated parts of western Pennsylvania, sending torrents down the streets of one town and requiring several people to be helped by swiftwater rescue specialists.
Zelienople (ZEE-lee-uh-no-pul) officials told drivers to avoid several streets because of severe flooding in the town about 30 miles (48 kilometers) north of Pittsburgh.
A powerful front that raked across the state late Tuesday brought high winds that scattered debris, downed trees and took out power lines.
Hard-hit areas included north and northeast of Pittsburgh and in northeastern Pennsylvania, from Towanda to Scranton.
The National Weather Service is investigating whether tornadoes touched down in Indiana or Lackawanna counties.
There were reports of large hail and some areas received 3 or 4 inches of rainfall over a short period.
