1815 New England hurricane
The Great September Gale of 1815 was a deadly and fast-moving Category 4 Atlantic hurricane in 1815 that became the second of five known major hurricanes to strike New England. At the time, it was the first hurricane to strike the greater area in 180 years.
After striking on Long Island, the hurricane caused major damage in Connecticut, Massachusetts, New Hampshire and Rhode Island. Rhode Island suffered the worst damage, as the storm surge flooded towns along Narragansett Bay up to and including Providence.
Origin
The summer of 1815 was reported to have been unusually stormy, possibly because of transient climate changes induced by ash clouds from the eruption of Mount Tambora in April.The hurricane first struck the Turks Islands near the Bahamas on September 20, with a strength estimated to have been equivalent to a Category 4 hurricane.
Impact
New York
The storm struck Long Island on September 23, 1815, probably coming ashore near Center Moriches around 7:00 A.M. On the south shore of Long Island it broke through the barrier beach and created the inlet that still isolates Long Beach, which had previously been an eastward extension of The Rockaways.Connecticut
Around 9:00 A.M. the storm came ashore at Saybrook, Connecticut with the force of what would now be considered a Category 3 hurricane. Waves of up to six feet were reported in New London.Rhode Island
The "Great Storm", as it was known there, hit Providence, Rhode Island on the morning of September 23. From about 10:00 A.M. to noon, the storm delivered a storm surge that funneled up Narragansett Bay where it destroyed some 500 houses and 35 ships. Dozens of ships were deposited on the streets of Providence. The bowsprit of the ship "Ganges" was smashed into the third story of the Washington Insurance Company building. The Second Baptist Meeting House was destroyed. Most of the buildings on the east side from south of the Market House to India Point were destroyed. At India Point, houses and wharves were destroyed. Both the Washington Bridge and the Central (Red) Bridge were uprooted from their piers and destroyed.The rain appears to have been saturated with salt. The leaves on trees which were not blown away were covered with a white salt coating that resembled a light frost. Even houses turned white.
A line on the Old Market Building marks the storm surge that was unsurpassed in the city until the 1938 New England hurricane, which brought a storm surge. There is still a worn plaque on the Rhode Island Hospital Trust building, along with a newer plaque showing the higher 1938 hurricane water level. At Matunuck, Rhode Island, sediment studies have identified the overwash fan of sediments in Succotash Marsh, where the 1815 hurricane storm surge overtopped the barrier beach.
The financial loss was estimated at one and a half million dollars, one-quarter the total valuation of the city. Fortunately, only two people died, both in India Point.
After the storm, much of the Narragansett Bay area was rebuilt with higher riverbanks, raised wharves, and more durable building practices, to help protect against future storms.
