The 1881 Atlantic hurricane season featured a tropical cyclone that remains one of the deadliest in the history of the United States. Seven tropical storms are known to have developed, four of which strengthened into hurricanes, though none of those intensified into a major hurricane. 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. In 2004, meteorologist Christopher Landsea concluded that the official hurricane database (HURDAT) excludes zero to six tropical cyclones per year between 1851 and 1885 and zero to four per year between 1886 and 1910. 7 storms, 4 hurricanes, 0 major hurricanes (Category 3+). Strongest: an unnamed storm (105 mph). Accumulated cyclone energy ≈ 59. Wiki link
