Tropical cyclones in 2018


During 2018, 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 151 tropical cyclones had formed this year to date. 102 tropical cyclones were named by either a Regional Specialized Meteorological Center or a Tropical Cyclone Warning Center.
The most active basin in the year was the Western Pacific, which documented 28 named systems, while the Eastern Pacific, despite only amounting to 23 named systems, including an unnamed subtropical cyclone, was its basin's hyperactive and produced the highest Accumulated cyclone energy in only season since 1992. Conversely, both the North Atlantic hurricane and North Indian Ocean cyclone seasons experienced the average number of cyclones reaching tropical storm intensity in recorded history, numbering 15 and 7, respectively. Activity across the southern hemisphere's three basins—South-West Indian, Australian, and South Pacific—was spread evenly, with each region recording seven named storms apiece.
The costliest tropical cyclone of the year was Hurricane Michael in the Atlantic which struck Florida in October causing US$25.1 billion in damage. The deadliest tropical cyclone of the year was Tropical Storm Son-Tinh in the West Pacific which killed 170 people in Vietnam and Laos.

Global atmospheric and hydrological conditions

Northern Atlantic Ocean

In the North Atlantic Ocean, atmospheric and hydrological conditions were generally unfavorable for tropical cyclogenesis. In the tropical Atlantic, sea surface temperatures were cooler than average, characteristic of a negative phase of the Atlantic Multidecadal Oscillation. Additionally, high quantities of Saharan dust along with stronger than average upper-level wind shear over the tropical Atlantic created an unfavorable atmospheric environment. Despite the unfavorable conditions present, activity in the tropical Atlantic was plentiful, with Hurricanes Beryl, Florence, Helene, Isaac, and Michael developing in the region. On the contrary, conditions in the subtropical Atlantic were more conducive to tropical cyclone formation, with sea surface temperatures being warmer than average. Six tropical cyclones: Beryl, Chris, Debby, Ernesto, Joyce and Leslie, developed or reformed in the subtropical Atlantic.

Systems

January

A total of thirteen tropical systems of all intensities were monitored during January 2018, of which seven developed further and were named by the various warning centres. As the year opened a tropical depression that was being monitored by the JMA within the Western Pacific, while a weak tropical low existed within the Australian region to the south of Sumatra. During that day, the depression entered PAGASA's self-defined area of responsibility, where it was assigned the name Agaton. In the middle of the month, Cyclone Berguitta passed very close to Mauritius and Réunion, causing millions in damages and a fatality. The only system to cause significant damage was Tropical Cyclone Fehi which caused tens of millions in damages when it brought severe flooding to New Zealand in late January.

February

The month of February was inactive, with only six tropical cyclones forming. However, Cyclone Gita became the most intense tropical cyclone to affect Tonga since records began. Gita was also one of the worst tropical cyclones to affect the island nation, causing significant agricultural and structural damages totalling in the hundreds of millions as well as a couple fatalities. Tropical Storm Sanba was a system that made landfall in the Philippines, resulting in a few million in damage and over a dozen fatalities. Cyclone Kelvin was unusual in that it maintained a healthy structure over land through a process known as the brown ocean effect, leading to tens of millions in damages.
