The 1871 Atlantic hurricane season lasted from mid-summer to late-fall. Records show that 1871 featured two tropical storms, four hurricanes and two major hurricanes (Category 3+). 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 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. According to a study in 2004, 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 is possible. A later study in 2008 estimated th
