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 (RSMC) or a Tropical Cyclone Warning Center (TCWC).

Contents

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 (ACE) 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 (AMO). [1] 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, [2] Florence, [3] Helene, [4] Isaac, [5] 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, [6] Chris, [7] Debby, [8] Ernesto, [9] Joyce [10] and Leslie, [11] developed or reformed in the subtropical Atlantic.

January

Cyclone Cebile Cebile 2018-01-31 0525Z.jpg
Cyclone Cebile

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

Cyclone Gita Gita 2018-02-14 0150Z.jpg
Cyclone Gita

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.

In the middle of the month, Cyclone Eliakim made landfall in Madagascar, causing close to two dozen deaths and an unknown amount of damage. Also forming in the middle of month, Cyclone Marcus was a very intense tropical cyclone that affected the Tanimbar Islands, Top End, and Kimberley, causing tens of millions in damages. Cyclone Iris was a very long lived system that formed several days later, lasting for nearly four weeks as a tropical cyclone before dissipating in mid-April. Cyclone Josie was a system that formed in late March. It affected southern Fiji, causing millions in damages and several deaths.

Tropical cyclone warnings and watches are two levels of alert issued by national weather forecasting bodies to coastal areas threatened by the imminent approach of a tropical cyclone of tropical storm or hurricane intensity. They are notices to the local population and civil authorities to make appropriate preparation for the cyclone, including evacuation of vulnerable areas where necessary. It is important that interests throughout the area of an alert make preparations to protect life and property, and do not disregard it on the strength of the detailed forecast track. Tropical cyclones are not points, and forecasting their track remains an uncertain science,

1957 Atlantic hurricane season hurricane season in the Atlantic Ocean

The 1957 Atlantic hurricane season featured the one of longest travelling tropical cyclones in the Atlantic basin, Hurricane Carrie. Nevertheless, the season was generally inactive with eight tropical storms – two of which went unnamed – and three hurricanes, two of which intensified further to attain major hurricane intensity. The season officially began on June 15 and ended on November 15, though the year's first tropical cyclone developed prior to the start of the season on June 8. The final storm dissipated on October 27, well before the official end of the season. The strongest hurricane of the year was Carrie, which reached the equivalent of a Category 4 hurricane on the Saffir–Simpson hurricane scale on two separate occasions in the open Atlantic; Carrie later caused the sinking of the German ship Pamir southwest of the Azores, resulting in 80 deaths.

1998 Pacific typhoon season typhoon season in the Pacific Ocean

The 1998 Pacific typhoon season was at the time the least active Pacific typhoon season on record, until the record was surpassed 12 years later, spawning 16 tropical storms and 8 typhoons. The scope of this article is limited to the Pacific Ocean, north of the equator and west of the international date line. Storms that form east of the date line and north of the equator are called hurricanes; see 1998 Pacific hurricane season. Tropical Storms formed in the entire west Pacific basin were assigned a name by the Joint Typhoon Warning Center. Tropical depressions in this basin have the "W" suffix added to their number. Tropical depressions that enter or form in the Philippine area of responsibility are assigned a name by the Philippine Atmospheric, Geophysical and Astronomical Services Administration or PAGASA. This can often result in the same storm having two names.

1996 Pacific typhoon season typhoon season in the Pacific Ocean

The 1996 Pacific typhoon season has no official bounds; it ran year-round in 1996, but most tropical cyclones tend to form in the northwestern Pacific Ocean between May and November. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean.

1995 Pacific typhoon season typhoon season in the Pacific Ocean

The 1995 Pacific typhoon season occurred all year round, unusual in that most tropical cyclones tend to form in the northwestern Pacific Ocean between May and November.

1993 Pacific typhoon season typhoon season in the Pacific Ocean

The 1993 Pacific typhoon season has no official bounds; it ran year-round in 1993, but most tropical cyclones tend to form in the northwestern Pacific Ocean between May and November. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean.

1990 Pacific typhoon season typhoon season in the Pacific Ocean

The 1990 Pacific typhoon season was another active season. It has no official bounds; it ran year-round in 1990, but most tropical cyclones tend to form in the northwestern Pacific Ocean between May and November. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean.

Pacific hurricane Mature tropical cyclone that develops within the eastern and central Pacific Ocean

A Pacific hurricane is a mature tropical cyclone that develops within the northeastern and central Pacific Ocean to the east of 180°W, north of the equator. For tropical cyclone warning purposes, the northern Pacific is divided into three regions: the eastern, central, and western, while the southern Pacific is divided into 2 sections, the Australian region and the southern Pacific basin between 160°E and 120°W. Identical phenomena in the western north Pacific are called typhoons. This separation between the two basins has a practical convenience, however, as tropical cyclones rarely form in the central north Pacific due to high vertical wind shear, and few cross the dateline.

1970 Pacific typhoon season typhoon season in the Pacific Ocean

The 1970 Pacific typhoon season has no official bounds; it ran year-round in 1970, but most tropical cyclones tend to form in the northwestern Pacific Ocean between June and December. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean.

1974 Pacific typhoon season typhoon season in the Pacific Ocean

The 1974 Pacific typhoon season has no official bounds; it ran year-round in 1974, but most tropical cyclones tend to form in the northwestern Pacific Ocean between June and December. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean.

1973 Pacific typhoon season typhoon season in the Pacific Ocean

The 1973 Pacific typhoon season has no official bounds; it ran year-round in 1973, but most tropical cyclones tend to form in the northwestern Pacific Ocean between June and December. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean.

Atlantic hurricane tropical cyclone that forms in the North Atlantic Ocean

An Atlantic hurricane or tropical storm is a tropical cyclone that forms in the Atlantic Ocean, usually between the months of June and November. A hurricane differs from a cyclone or typhoon only on the basis of location. A hurricane is a storm that occurs in the Atlantic Ocean and northeastern Pacific Ocean, a typhoon occurs in the northwestern Pacific Ocean, and a cyclone occurs in the south Pacific or Indian Ocean.

Tropical cyclone rotating storm system with a closed, low-level circulation

A tropical cyclone is a rapidly rotating storm system characterized by a low-pressure center, a closed low-level atmospheric circulation, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain or squalls. Depending on its location and strength, a tropical cyclone is referred to by different names, including hurricane, typhoon, tropical storm, cyclonic storm, tropical depression, and simply cyclone. A hurricane is a tropical cyclone that occurs in the Atlantic Ocean and northeastern Pacific Ocean, and a typhoon occurs in the northwestern Pacific Ocean; in the south Pacific or Indian Ocean, comparable storms are referred to simply as "tropical cyclones" or "severe cyclonic storms".

Tropical cyclone basins area of tropical cyclone formation

Traditionally, areas of tropical cyclone formation are divided into seven basins. These include the north Atlantic Ocean, the eastern and western parts of the northern Pacific Ocean, the southwestern Pacific, the southwestern and southeastern Indian Oceans, and the northern Indian Ocean. The western Pacific is the most active and the north Indian the least active. An average of 86 tropical cyclones of tropical storm intensity form annually worldwide, with 47 reaching hurricane/typhoon strength, and 20 becoming intense tropical cyclones, super typhoons, or major hurricanes.

2018 Pacific typhoon season Period of formation of tropical cyclones in the Western Pacific Ocean in 2018

The 2018 Pacific typhoon season was at the time, the costliest Pacific typhoon season on record, until the record was beaten by the following year. The season was above-average, producing 29 storms, 13 typhoons, and 7 super typhoons. It was an event in the annual cycle of tropical cyclone formation, in which tropical cyclones form in the western Pacific Ocean. The season ran throughout 2018, though most tropical cyclones typically develop between May and October. The season's first named storm, Bolaven, developed on January 3, while the season's last named storm, Man-yi, dissipated on November 28. The season's first typhoon, Jelawat, reached typhoon status on March 29, and became the first super typhoon of the year on the next day.

2020 Pacific typhoon season Storm season

The 2020 Pacific typhoon season is a late-starting, ongoing event in the annual cycle of tropical cyclone formation, in which tropical cyclones form in the western Pacific Ocean. The season runs throughout the year, though most tropical cyclones typically develop between May and October. The season's first tropical cyclone developed on May 10, making it the sixth-latest start in the basin on record, just slightly behind 1973, and the most recent start since 2016.

Tropical cyclones in 2019 Wikimedia list article

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 143 systems formed with 105 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). Hurricane Dorian has the highest wind-speed, with 1-minute sustained wind speed of 185 mph (295 km/h).

Tropical cyclones in 2020 Wikimedia list article

Throughout 2020 so far, 36 tropical or subtropical cyclones have formed in bodies of water known as tropical cyclone basins. Of these, 23 have been named, including a subtropical cyclone in the South Atlantic, by various weather agencies when they attained maximum sustained winds of 35 knots. The strongest storm of the year so far is Cyclone Harold in the South Pacific Ocean. While the deadliest storm of the year so far is Cyclone Amphan in the North Indian Ocean, causing over 100 fatalities in India, Sri Lanka, and Bangladesh, also while causing castrostrophic damage in the latter country.
