ReplyThe Halloween Storm, also known as the Perfect Storm, refers to a severe weather event that occurred between October 28 and November 2, 1991, along the eastern seaboard of the United States and Canada. The storm was a rare combination of three weather systems - a nor'easter, a high-pressure system, and the remnants of Hurricane Grace - that converged to create a powerful extratropical cyclone.
