Among them, Mawar (second image in the second row) was the most intense with a minimum central pressure of 900 hPa.
During 2023, tropical cyclones formed in seven major bodies of water, commonly known as tropical cyclone basins. They were named by various weather agencies when they attained maximum sustained winds of 35 knots (65 km/h; 40 mph). Throughout the year, a total of 115 systems formed, with 79 of them being named. The most intense storm this year was Typhoon Mawar, which had a minimum pressure of 900 hPa (26.58 inHg). The deadliest tropical cyclone of the year was Storm Daniel, which killed at least 5,591 people in Libya, Greece, Turkey, and Bulgaria. Meanwhile, the costliest tropical cyclone was Typhoon Doksuri which caused at least $28.4 billion (USD) worth of damage in China, the Philippines and Taiwan, becoming the costliest on record outside the Atlantic Ocean basin. Among this year's systems, thirty became major tropical cyclones, of which nine intensified into Category 5 tropical cyclones on the Saffir–Simpson scale (SSHWS), the most since 2018[1]. The accumulated cyclone energy (ACE) index for the 2023 (seven basins combined), as calculated by Colorado State University (CSU) was 857.4 units, which was above the 1991-2020 mean of 770.2 units.[2][3]
The most active basin in the year was the North Atlantic Ocean, which had 20 named systems. The Eastern Pacific Ocean had an above-average and destructive season, with 17 named storms forming; 10 of those became hurricanes, of which 8 strengthened into major hurricanes – double the seasonal average. The Western Pacific Ocean had a total of 17 named storms, making it the second least active season in the basin, tying with 1998. The North Indian Ocean was unusually active, with six named storms forming, producing the second-most accumulated cyclone energy in this basin on record, only behind 2019. Activity across the southern hemisphere's three basins (South-West Indian, Australian, and South Pacific) was fairly significant, with the regions recording 17 named storms altogether, with the most intense Southern Hemisphere cyclone of the year, Cyclone Kevin in the South Pacific basin, peaking with a central pressure of 913 hPa (26.96 inHg).
Tropical cyclones were primarily monitored by ten warning centers across the world, which are designated as a Regional Specialized Meteorological Center (RSMC) or a Tropical Cyclone Warning Center (TCWC) by the World Meteorological Organization (WMO). These ten centers are the National Hurricane Center (NHC) and the Central Pacific Hurricane Center (CPHC), Japan Meteorological Agency (JMA), Indian Meteorological Department (IMD), Météo-France (MFR), Indonesia's Meteorology, Climatology, and Geophysical Agency (BMKG), the Australian Bureau of Meteorology (BoM), Papua New Guinea's National Weather Service (PNGNWS), the Fiji Meteorological Service (FMS), and New Zealand's MetService. Unofficial, but still notable, warning centres include the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA), the United States's Joint Typhoon Warning Center (JTWC), and the Brazilian Navy Hydrographic Center.
