Tropical cyclones in 2019

During 2019, tropical cyclones formed within seven different tropical cyclone basins, located within various parts of the Atlantic, Pacific and Indian Oceans. During the year, a total of 142 systems formed with 100 of these developing further and were named by the responsible warning centre. The strongest tropical cyclone of the year was Typhoon Halong, which was estimated to have a minimum barometric pressure of 905 hPa (26.72 inHg). Halong also had the highest 1-minute sustained winds of the year, at 305 kilometres per hour (190 mph).

Similar to the previous year, 2019 was above average in terms of the number of storms. The most active basin in the year was the Western Pacific, which documented 29 named systems. The Eastern Pacific had an average season, although many of the storms were rather weak and short-lived, therefore the number of hurricanes was the least since 2010 (7). The North Atlantic hurricane season experienced an above average number of tropical storm intensity systems, numbering 18, though most were rather weak and short-lived, especially late in the season. In the North Indian Ocean basin it was extremely active, breaking many records. This included Cyclone Kyarr, the second-strongest Arabian Sea Cyclone on record and one of the strongest cyclone ever in the North Indian Ocean. Activity across the southern hemisphere's three basins – South-West Indian, Australian, and South Pacific – was fairly significant, with the regions recording 25 named storms altogether, with the most intense Southern Hemisphere cyclone of the year, Cyclone Ambali from the Southwest Indian Ocean basin peaking with a central pressure of 930 hPa (27.46 inHg). Eight Category 5 tropical cyclones formed in 2019. The accumulated cyclone energy (ACE) index for the 2019 (seven basins combined), as calculated by Colorado State University (CSU) was 854.8 units.

The deadliest tropical cyclone of the year was Intense Tropical Cyclone Idai in the South-West Indian Ocean, which killed at least 1,303 people in Mozambique, Malawi, Zimbabwe, and Madagascar and the costliest tropical cyclone of the year was Typhoon Hagibis in the Western Pacific Ocean, which caused more than $15 billion in damage after striking Japan.
