The 1991 Perfect Storm, also known as The No-Name Storm and the Halloween Gale/Storm, was a nor'easter that absorbed Hurricane Grace, and ultimately evolved into a small unnamed hurricane itself late in its life cycle. The initial area of low pressure developed off the coast of Atlantic Canada on October 29. Forced southward by a ridge to its north, it reached its peak intensity as a large and powerful cyclone. The storm lashed the east coast of the United States with high waves and coastal flooding before turning to the southwest and weakening. Moving over warmer waters, the system transitioned into a subtropical cyclone before becoming a tropical storm. It executed a loop off the Mid-Atlantic states and turned toward the northeast. On November 1, the system evolved into a full-fledged hurricane, with peak sustained winds of 75 miles per hour, although the National Hurricane Center left it unnamed to avoid confusion amid media interest in the precursor extratropical storm. It later received the name "the Perfect Storm" after a conversation between Boston National Weather Service forecaster Robert Case and author Sebastian Junger.
