You basically had the equivalent of widespread F2 tornado damage between BOS and CT river. That’s catastrophic. 

I attended many simulations during my Emergency Manager days working for the Mashantuckets. There were shocking presentations put on by Eversource, months for many. One simulation was the 1635 cane That storm was absolutely a monster. It can happen.

least a strong Category 3 hurricane at landfall with 125 mph (201 km/h) sustained winds and a central pressure of 938 mbar (27.7 inHg) at the Long Island landfall and 939 mbar (27.7 inHg) at the mainland landfall. This would be the most intense known hurricane landfall north of Cape Fear, North Carolina if accurate. Jarvinen noted that the colonial hurricane may have caused the highest storm surge along the east coast in recorded history at 20 feet (6.1 m) near the head of Narragansett Bay. He concluded that "this was probably the most intense hurricane in New England history

How about 1675?  :damage:

The Second Great Colonial Hurricane or The New England Hurricane of 1675. A hurricane said to be almost as powerful as the 1635 New England Hurricane swept the New England coastal region. Blew down many trees in Connecticut, Rhode Island, and Massachusetts, and destroyed warves. Older colonists that experienced the 1635 hurricane said this one had similar characteristics placing it among New England's most destructive storms.[58]

Similar to reading a tree ring to tell the age of a tree and the climate conditions that existed in a given year, scientists can read the sediment cores to tell when intense hurricanes occurred.

The study’s authors found evidence of 32 prehistoric hurricanes, along with the remains of three documented storms that occurred in 1991, 1675 and 1635.

The prehistoric sediments showed that there were two periods of elevated intense hurricane activity on Cape Cod – from 150 to 1150 and 1400 to 1675. The earlier period of powerful hurricane activity matched previous studies that found evidence of high hurricane activity during the same period in more southerly areas of the western North Atlantic Ocean basin – from the Caribbean to the Gulf Coast. The new study suggests that many powerful storms spawned in the tropical Atlantic between 250 and 1150 also battered the US East Coast.

The deposits revealed that these early storms were more frequent, and in some cases were likely more intense, than the most severe hurricanes Cape Cod has seen in historical times, including Hurricane Bob in 1991 and a 1635 hurricane that generated a 20-foot storm surge, according to Donnelly.

High hurricane activity continued in the Caribbean and Gulf of Mexico until 1400, although there was a lull in hurricane activity during this time in New England, according to the new study. A shift in hurricane activity in the North Atlantic occurred around 1400 when activity picked up from the Bahamas to New England until about 1675.

The periods of intense hurricanes uncovered by the new research were driven in part by intervals of warm sea surface temperatures that previous research has shown occurred during these time periods, according to the study.  Previous research has also shown that warmer ocean surface temperatures fuel more powerful storms.

The sediment coring and analysis by Donnelly and his colleagues “is really nice work because it gives us a much longer period perspective on hurricanes,” said Kerry Emanuel, a professor of atmospheric science at the Massachusetts Institute of Technology in Cambridge. “It gives you something that you otherwise wouldn’t have any knowledge of.”

“The ability to produce and synthesize thousands of years of data on hurricane paths and frequencies is revolutionizing our understanding of what controls where and how often these dangerous storms make landfall,” said Candace Major, program director in the National Science Foundation’s Division of Ocean Sciences, which funded the research.

Medieval warm period?

Pickles laughed, but I was being serious. That warm period from about 900-1200 enabled the vikings to live up on Greenland. The world as a whole was a bit warmer…probably warmer waters for stronger canes as well.

Did the Black Plague Curb the Vikings carbon footprint to save the earth in a heart warming way that people were marketed at , while smart businesses made profit off of the new industry trends

Given the Vikings’ diet, one might assume there was an abnormally high amount of methane being farted into the atmosphere back then.

Geez , Hopefully the middle age  Brain trust recognized this and started laying the Ground work to morph social Opinion to be able to  tax the air and bought up  the farmland for the good of all the critical thinking Viking  public not guided by their heart strings being pulled or their need to seem socially with it
