exact origin of the hurricane is unknown, though modern historians estimated it developed near the Cape Verde Islands in early October. The system strengthened and grew in size as it tracked slowly westward and first began affecting Barbados late on October 9. Late on October 10, the worst of the hurricane passed over the island. Early on October 11, the hurricane turned north-northwest about east of Saint Lucia, and later that night it neared the island of Martinique.

The exact origin of the hurricane is unknown, though modern historians estimated it developed near the Cape Verde Islands in early October. The system strengthened and grew in size as it tracked slowly westward and first began affecting Barbados late on October 9. Late on October 10, the worst of the hurricane passed over the island. Early on October 11, the hurricane turned north-northwest about east of Saint Lucia, and later that night it neared the island of Martinique. The cyclone gradually weakened as it passed to the southwest of Dominica early on October 12 and subsequently struck the island of Guadeloupe.
After hitting Guadeloupe, the hurricane turned west-northwest, passing about southwest of Saint Kitts. The hurricane steadily neared Puerto Rico as it paralleled the southern coastline, and made its closest point of approach on October 14 to the southwest portion of the island. It subsequently turned to the northwest, hitting the island of Mona in the Mona Passage before making landfall near the current-day Dominican Republic province of Samaná. Late on October 15 it reached the Atlantic Ocean and after passing about east of Grand Turk Island, it is estimated to have recurved to the northeast. The hurricane passed southeast of Bermuda on October 18, and was last observed two days later about southeast of Cape Race, Newfoundland.
On October 19, strong winds and high tides were reported in northeastern Florida. One modern historian suggested the hurricane passed much closer to the state than previously thought. Another possibility considered was an extension to a hurricane in the western Caribbean Sea. Due to lack of data, the exact track of the Great Hurricane is unknown.
Impact
The Great Hurricane persisted near Barbados for about two days, producing violent winds which were described as "so deafening that people could not hear their own voices." The winds stripped the bark off trees before the hurricane downed every tree on the island. This phenomenon has not been observed in any of the strongest modern-day tropical cyclones, so, according to meteorologist Dr. Jose Millas, for it to have been done by winds and rain alone would require winds over 200 mph (320 km/h). The winds also destroyed every house on Barbados. Most ships at the bay broke free of their moorings from the hurricane's rough surf and all forts on the island were destroyed. The winds and seas moved heavy cannons about . About 4,500 people died on the island.
In Saint Vincent, the hurricane destroyed 584 of the 600 houses in Kingstown. At Grenada, 19 Dutch ships were wrecked. On Saint Lucia, rough waves and a strong storm tide destroyed the fleet of British Admiral Rodney at Port Castries, with one ship destroying the city's hospital by being lifted on top of it. The hurricane destroyed all but two houses at Port Castries, and throughout the island about 6,000 perished.
A fleet of 40 French ships involved in the American Revolutionary War capsized as a result of the hurricane off Martinique; about 4,000 soldiers drowned. The hurricane produced a storm surge on Martinique, destroying all houses in Saint-Pierre; 9,000 died on the island. Severe damage was reported on Dominica, Guadeloupe, Antigua, and Saint Kitts, though it is unknown if any died on those islands. Additionally, many ships were washed ashore on Saint Kitts. A powerful storm surge affected the island of Sint Eustatius, causing 4,000 to 5,000 fatalities.
Heavy damage was reported in southern Puerto Rico, primarily in Cabo Rojo and Lajas. Severe damage also occurred in the eastern region of the Dominican Republic. The hurricane later grounded 50 ships near Bermuda. Throughout its path, the hurricane killed over 27,500 people, making it the deadliest hurricane in Atlantic hurricane history.
