A potent cluster of thunderstorms that ripped down trees and flooded roads in parts of the region may have spawned a tornado in South Jersey on Friday afternoon. The National Weather Service said it would send a team of investigators to Atlantic County to determine whether damages were the result of straight-line winds or the kind that blow in circles.

After a chaotic and emotional day, the clean-up effort in Collings Lakes, New Jersey, is just beginning in this community.
