The 1873 Atlantic hurricane season was quiet, with only two tropical storms and three hurricanes, two of which were major hurricanes (Category 3+), being recorded. However, in the absence of modern satellite and other remote-sensing technologies, only storms that affected populated land areas or encountered ships at sea were recorded, so the actual total could be higher. An undercount bias of zero to six tropical cyclones per year between 1851 and 1885 and zero to four per year between 1886 and 1910 has been estimated. Of the known cyclones, large alterations were made to the tracks of Hurricane Two and Hurricane Five in 1995 by Jose Fernandez-Partagas and Henry Diaz, who also proposed smaller changes to the known track of Hurricane Three. All of the tropical cyclones, other than Hurricane Two, made landfall in Florida. Season summary The Atlantic hurricane database, HURDAT, recognizes five tropical cyclones for the 1873 season. Three storms attained hurricane status, with winds of 75 mph (119 km/h) or greater. The second and fifth hurricanes of the season were the most intense, with maximum sustained winds up to 120 mph (190 km/h). The first storm of the season was a tropical storm that developed near the Bahamas on June 1 and made landfall near the Florida/Georgia border the next day before dissipating. The most notable storm of the season was Hurricane Two. It formed as a tropical storm on August 13 in the Atlantic and became a hurricane on August 17. It made landfall at Newfoundland on August 26 and became extratropical the next day. The hurricane caused a great deal of damage and great loss of life. Hurricane Three was first seen in the Gulf of Mexico on September 18. It struck Florida the next day and passed over Georgia and South Carolina before dissipating on September 20. The second tropical storm of the season traveled from the Gulf of Mexico across Florida between September 22 and September 24. The final hurricane of the season formed in the eastern Caribbean on September 26 before reaching Haiti. It weakened and restrengthened to a major hurricane before hitting Florida on October 7. The storm became extratropical on October 9 and dissipated the next day. Timeline Systems Tropical Storm One The first storm of the season developed on June 1 over the western Bahamas. It moved northward before turning and striking near the Florida/Georgia border on June 2.
