The 1889 Atlantic hurricane season featured the first known tropical cyclone in the basin to attain hurricane status in the month of May. Of the nine known tropical storms, six intensified into hurricanes, but none of those strengthened 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. Therefore, 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. The first system was initially over the western Atlantic Ocean on May 16, while the ninth and final storm transitioned into an extratropical cyclone just prior to striking Nova Scotia on October 7. 9 storms, 6 hurricanes, 0 major hurricanes (Category 3+). Strongest: an unnamed storm (110 mph). Accumulated cyclone energy ≈ 104. Wiki link
