The hurricane was at its deadliest and most destructive in the Caribbean and Bahamas, claiming as many as 455 lives there, though some estimates of the dead were higher. Heavy rainfall in Puerto Rico led to flash flooding that exacted a toll of 25 lives and $5 million in losses. Similar phenomena, along with shipwrecks, in the Dominican Republic killed 162 people and induced a loss of $3 million. The worst to impact New Providence and the city of Nassau since 1866, the cyclone ravaged the Bahaman archipelago, destroying roughly 20% of the sponging fleet there, flattening entire communities on many of the islands, and causing as many as 400 fatalities. The impacts were so severe that many Bahamians were temporarily forced to migrate to the United States. Damage from the Miami and Havana–Bermuda hurricanes subsequently compounded recovery, adding over a hundred additional casualties. In the United States, particularly Florida, the storm caused comparatively modest damage, mainly to coastal structures, though heavy rainfall and tornadoes also attended the storm. 10 deaths were reported in the state of Florida, though high tides and prolific rains extended farther north, along the Southeastern coastline. In all, the storm killed at least 464 people—unofficially up to 598—and inflicted at least $19.1 million in damages.

Meteorological history

At 06:00 UTC on July 22, the Atlantic hurricane database (HURDAT) initialized a weak tropical storm, with maximum sustained winds of 40 mph (65 km/h), 200 miles (320 kilometres) east of Barbados, an outpost of the Windward Islands. Operationally, the cyclone was first noted 190 mi (305 km) farther northwest, near 14°30′N 58°42′W / 14.5°N 58.7°W, on the same date. Quickly strengthening, the cyclone headed generally west-northwestward, crossing the northern tip of Martinique. Entering the eastern Caribbean early on July 23, it became a minimal hurricane six hours later, and gradually intensified to its first peak of 105 mph (165 km/h) by 18:00 UTC. As it did so, the cyclone began turning northwestward, toward coastal southwestern Puerto Rico, and made landfall over present-day Cabo Rojo National Wildlife Refuge early on July 24. At the time, it was equivalent to a Category 2 hurricane.

Over the next day, the cyclone crossed the Mona Passage and skirted the coastal northeastern Dominican Republic; in the meantime its winds decreased to 85 mph (140 km/h) due to interaction with Hispaniola. Early on July 25, however, a period of rapid deepening commenced: within 18 hours the cyclone successively attained winds of 111 mph (178 km/h) or more—equivalent to a major hurricane on the modern-day Saffir–Simpson scale—and then 130 mph (215 km/h), making it a Category 4 storm. At 00:00 UTC on July 26, the cyclone reached its estimated peak of 140 mph (220 km/h), with central pressure of about 938 mb (27.7 inHg); this made it the strongest Atlantic hurricane on record in the month of July until Hurricanes Dennis and Emily in 2005.

During its peak the cyclone tore through the Bahamas as a potent hurricane, though few meteorological observations were available near the storm's eye. Largely maintaining its force, the storm passed near or over the Bahamian capital Nassau. After passing New Providence, the cyclone began to gradually weaken and its forward speed decreased. As it did so, the western flank of the Azores High—a seasonal ridge of high atmospheric pressure—eroded, allowing a northward shift. By 06:00 UTC on July 27 the cyclone lost major-hurricane status and turned north-northwestward, nearing coastal eastern Florida. Sideswiping the Indian River, the storm continued to gradually weaken, and made landfall near New Smyrna at 10:00 UTC on July 28. At the time, the storm featured a smaller-than-average eye size and a central pressure near 967 mb (28.6 inHg), both of which suggested winds of 105 mph (165 km/h).

After landfall, the storm quickly weakened and resumed a northwestward course. Eight hours after moving inland, it shed hurricane status. A day later, after crossing Georgia, the cyclone degenerated into a tropical depression and headed westward over Alabama. Late on July 30, the depression began curving northward over Mississippi, and spent nearly three additional days heading northeastward. The system traversed the Mississippi and Ohio valleys before encountering the Great Lakes region. It became extratropical early on August 1 and dissipated over southern Ontario a day and a half later.
