The 1991 Perfect Storm was a nor’easter that absorbed Hurricane Grace, and ultimately evolved into a small unnamed hurricane. The storm lashed the east coast of the United States with high waves and coastal flooding before turning to the southwest and weakening. A buoy off the coast of Nova Scotia reported a wave height of 100. 7 feet, the highest ever recorded in the province’s offshore waters.
About 1991 Perfect Storm in brief
The 1991 Perfect Storm was a nor’easter that absorbed Hurricane Grace, and ultimately evolved into a small unnamed hurricane itself late in its life cycle. The storm lashed the east coast of the United States with high waves and coastal flooding before turning to the southwest and weakening. The system was the twelfth and final tropical cyclone, the eighth tropical storm, and fourth hurricane in the 1991 Atlantic hurricane season. Damage from the storm totaled over USD 200 million and the death toll was thirteen. In the middle of the storm, the fishing vessel Andrea Gail sank, killing her crew of six and inspiring the book, and later movie, The Perfect Storm. A buoy off the coast of Nova Scotia reported a wave height of 100. 7 feet, the highest ever recorded in the province’s offshore waters. More than 38,000 people were left without power, and along the coast high waves inundated roads and buildings. In Massachusetts, where damage was heaviest, over 100 homes were destroyed or severely damaged, including the vacation home of then-President George H. W. Bush. The Tropical Storm that formed late in the storm’s duration caused little impact, limited to power outages and slick roads; one person was killed in Newfoundland from a traffic accident related to the storm. The tropical system weakened, striking Nova Scotia as a tropical storm before dissipating. It was the last storm to make landfall in the U.S. during the 1991 hurricane season, and the first since Hurricane Katrina in 2005. It is also known as The No-Name Storm and the Halloween GaleStorm, as well as the Halloween Storm of 1991.
It became the highest-ever wave height on the oceanic shelf of the Shelfian Shelf, which is the sea shelf off Cape Cod, Massachusetts. It also became the second-highest wave height in Atlantic Canada, after a wave that reached 100.7 feet on October 30. The wave was recorded by a buoy located south of Halifax, Nova Scotia, and was the highest wave ever recorded on the Atlantic coast of North America. It has since been surpassed by a wave of 100 feet recorded on October 31, 2011. The PerfectStorm was the fourth hurricane of the 1991 season and the 12th tropical storm in the Atlantic Ocean. It had an unusual retrograde motion for a nor-easter, beginning a set of meteorological circumstances that occur only once every 50 to 100 years. It reached its peak intensity at approximately 12:00 UTC on October 12 with its lowest pressure of 972 millibars. The interaction between the extratropical system and the high pressure system created a significant pressure gradient, which created a strong winds and strong waves. It then weakened to a tropical system, which struck Nova Scotia on October 14. It later weakened again to a subtropical cyclone. It eventually weakened again, striking the coast again on October 15. On October 28, a ridge extended from the Appalachian Mountains northeastward to Greenland, with a strong high pressure center over eastern Canada. The blocking ridge forced the extatropical low to track toward the southeast and later to the west.
