[nb 1] However, due to the absence of remote-sensing satellite and other technology, only storms that affected populated land areas or encountered ships at sea were recorded; therefore, the actual total could be higher.

[4] However, climate researcher Michael Chenoweth authored a reanalysis study, published in 2014, which concluded that the 1876 season featured a total of 12 tropical cyclones.

The system crossed the Lesser and Greater Antilles, causing particularly severe impacts on Puerto Rico, including at least 19 deaths.

The hurricane and its remnants then impacted the Northeastern United States, with $30,000 (1876 USD) in damage on the barrier islands of Cape May County, New Jersey, alone.

[nb 2] In early October, the fourth storm struck Nicaragua, rendering about $5 million in damage and leaving approximately 20 deaths.

Later that month, the fifth and final known storm caused damage in the Cayman Islands, Cuba, and Florida prior to being last noted just northeast of Bermuda on October 23.

[6] The first storm of the season, initially observed by three ships on September 9, was a hurricane that existed for two days offshore Atlantic Canada.

[3][8][9] The season's fourth cyclone and third to form in the month of September struck Nicaragua in early October, leaving about $5 million in damage and about 20 deaths.

[10] Later, the fifth and final known storm impacted the Cayman Islands, Cuba, and Florida before being last detected to the northeast of Bermuda on October 23.

[11] Because the Alfred observed a barometric pressure of 970 mbar (29 inHg), HURDAT begins the track of this cyclone as a hurricane with winds of 90 mph (150 km/h) about halfway between Bermuda and Nova Scotia.

[5] Climate researcher Michael Chenoweth theorized that this storm began as a tropical depression near the Cabo Verde Islands on September 2.

Chenoweth's study, published in 2014, notes that the cyclone intensified into a tropical storm by the following day and moved generally northwestward until September 7.

By early the next day, the cyclone briefly intensified into a Category 3 hurricane, peaking with winds of 115 mph (185 km/h), several hours before striking Puerto Rico between Yabucoa and Humacao.

The system moved west-northwestward across the Mona Passage and struck the Dominican Republic, weakening to a tropical storm on September 14 as it traversed Hispaniola.

Thereafter, the storm briefly re-attained hurricane status while crossing the Windward Passage early on the next day and soon made landfall in Cuba near San Antonio del Sur.

Weakening to a tropical storm, the cyclone continued west-northwestward until turning northward over the central part of the island, barely avoiding Florida on September 16.

[12] In Puerto Rico, the storm was remembered as the "San Felipe Hurricane" because it struck on September 13, the feast day of Saint Philip.

Exactly 52 years later, Puerto Rico was struck by Hurricane San Felipe Segundo, a much more destructive and powerful cyclone.

Overflowing rivers and the storm itself carried away many bridges and caused significant losses to coffee, rice, and sugarcane estates.

Additionally, the cyclone attains a much stronger intensity, peaking with winds of 150 mph (240 km/h), equivalent to Category 4 status.

[17] It attained a peak intensity of 115 mph (185 km/h) just before making landfall on Bejucal in western Cuba, where the barometer dropped as low as 958 mbar (28.3 inHg) on October 19.

[3] About six hours later, early on October 20, the hurricane made landfall on the mainland near Chokoloskee with winds of 105 mph (165 km/h) and emerged into the Atlantic near Sebastian around 12:00 UTC.

[5] On Grand Cayman, where west winds occurred during the closest approach of the cyclone, severe damage and the destruction of 170 houses was reported.

[20] The storm disrupted communications via telegram across the island of Cuba,[21] although the most significant damage occurred in Havana and Matanzas provinces.

[23] On the Lake Worth Lagoon, the cyclone snapped or blew down large mastic and banyan trees, each more than 3 ft (0.9 m) in diameter and believed to have been hundreds of years old.

After the storm, the Atlantic Ocean appeared yellowish-brown due to silt, and numerous fish and sea mammals, including porpoises, were found beached.

Chenoweth theorized that the storm briefly attained hurricane status on the following day before weakening to a tropical depression and dissipating roughly halfway between Bermuda and Nova Scotia.

Moving north-northwestward, the cyclone passed just west of Barbados that day and briefly attained hurricane status.
