Background and detail

Background. 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. 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 storm was fast-moving, and after striking Long Island it caused major damage in Connecticut, Massachusetts, New Hampshire, and Rhode Island.

Impact. Rhode Island suffered the worst damage, with storm surges flooding towns along Narragansett Bay up to Providence. A line on the Old Market Building marks the 11-foot surge, which remained unsurpassed until 1938. In Dorchester, Massachusetts, the storm destroyed the arch of the bridge over the Neponset River. Sediment studies at Matunuck confirm the surge overtopped the barrier beach.

Contemporary Analysis. In an 1819 paper, an author concluded that the storm "appears to have been a moving vortex and not the rushing forward of a great body of the atmosphere." In Providence, the event was known as the "Great Storm" or "Great Gale." A worn plaque on the Rhode Island Hospital Trust building, built in 1917, marks the storm's water level, alongside a newer plaque showing the higher 1938 hurricane water level.
