Part of the 1893 Atlantic hurricane season

Hurricane San Roque was a destructive tropical cyclone in August 1893 that principally affected Puerto Rico, eastern New England, and Atlantic Canada. Its informal name in Puerto Rico arises from the feast day of Saint Roch, or San Roque in Spanish, which coincided with the hurricane's landfall on that island.[nb 1] It was the third known hurricane of the 1893 Atlantic hurricane season. The system was first observed on August 13 at low latitudes east of the Lesser Antilles. It grew to be a powerful, slow-moving hurricane in the Caribbean Sea, and on August 17 struck Puerto Rico at the equivalence of Category 3 on the modern-day Saffir–Simpson scale. The eye crossed the island from southeast to northwest in about seven hours. A prolonged period of strong winds caused widespread destruction on the island, most notably along the northern coast. Large numbers of homes sustained varying degrees of damage, with flimsy shacks belonging to poor workers faring the worst; many families were left homeless, and four people were killed. Telegraph communications were severed across the island. In addition to the intense winds, several days of heavy rainfall in interior sectors triggered extensive river flooding. The combined effects of rain and wind destroyed fields of crops, most notably coffee and sugar cane.

On August 19, the hurricane began to turn northeastward, accelerate, and gradually weaken. Although its center remained far from the United States, heavy rainfall and gale-force winds overspread the country's East Coast on August 20 and 21. Eastern New England experienced conditions akin to a particularly bad nor'easter, with winds as high as 72 mph (116 km/h) recorded on Block Island. Across Rhode Island and Massachusetts, grain crops were flattened and orchards were stripped of their fruits. The racing yacht Volunteer was badly damaged, and a fishing schooner sank off Nantucket; only one of the seven crew members managed to survive, by clinging to debris for 33 hours. Later that day, the now-rapidly moving cyclone made landfall in Nova Scotia. Damage to utility wires in Halifax cut power and communications services, and a child was killed by a downed power line. The storm wrought havoc on ships and boats throughout Atlantic Canada, becoming "one of the most notorious marine storms in the history of Nova Scotia".[4] The greatest maritime tragedy was the wreck of the steamship Dorcas and its barge, Etta Stewart, which struck a rocky shoal while underway east of Halifax. Dorcas capsized and was driven ashore, while the barge broke up in the pounding surf. All crew members and passengers on the two vessels, totaling 24 people, were killed. Two more people died when their boat sank on Trinity Bay in Newfoundland, for a storm total of 37 fatalities.
