2018 Pacific typhoon season

The **2018 Pacific typhoon season** is an ongoing event in the annual cycle of tropical cyclone formation, in which tropical cyclones form in the western Pacific Ocean. The season runs throughout 2018, though most tropical cyclones typically develop between May and October. The season's first named storm, Bolaven, developed on January 3. 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.

The scope of this article is limited to the Pacific Ocean, to the north of the equator between 100°E and the 180th meridian. Within the northwestern Pacific Ocean, there are two separate agencies that assign names to tropical cyclones, which can often result in a cyclone having two names, one from the JMA and one from PAGASA. The Japan Meteorological Agency (JMA) will name a tropical cyclone should it be judged to have 10-minute sustained wind speeds of at least 65 km/h (40 mph) anywhere in the basin, whilst the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) assigns names to tropical cyclones which move into or form as a tropical depression in their area of responsibility located between 135°E and 115°E and between 5°N–25°N regardless of whether or not a tropical cyclone has already been given a name by the JMA. Tropical depressions that are monitored by the United States' Joint Typhoon Warning Center (JTWC) are given a number with a "W" suffix.

A tropical depression formed on July 3. On the next day, the system intensified into Tropical Storm Maria. Early on July 5, Maria intensified into a severe tropical storm, while the JTWC classified the system as a Category 1 typhoon. Explosive intensification ensued, and later that day, Maria became a super typhoon and the first Category 5-equivalent storm of this basin since Nock-ten in 2016. Shortly afterwards, Maria underwent an eyewall replacement cycle, and it weakened below super typhoon status the following day. By July 8, however, Maria had completed the eyewall replacement cycle and regained Category 5-equivalent intensity.

## Storm Names

Within the Northwest Pacific Ocean, both the Japan Meteorological Agency (JMA) and the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) assign names to tropical cyclones that develop in the Western Pacific, which can result in a tropical cyclone having two names. The Japan Meteorological Agency's RSMC Tokyo — Typhoon Center assigns international names to tropical cyclones on behalf of the World Meteorological Organization's Typhoon Committee, should they be judged to have 10-minute sustained windspeeds of 65 km/h (40 mph). PAGASA names to tropical cyclones which move into or form as a tropical depression in their area of responsibility located between 135°E and 115°E and between 5°N and 25°N even if the cyclone has had an international name assigned to it. The names of significant tropical cyclones are retired, by both PAGASA and the Typhoon Committee. Should the list of names for the Philippine region be exhausted then names will be taken from an auxiliary list of which the first ten are published each season. Unused names are marked in gray.

### **International names**

A tropical cyclone is named when it is judged to have 10-minute sustained windspeeds of at least 65 km/h (40 mph). The JMA selected the names from a list of 140 names, that had been developed by the 14 members nations and territories of the ESCAP/WMO Typhoon Committee. The next 28 names on the naming list are listed here along with their international numeric designation, if they are used. During the season, the names Ampil and Jongdari were used for the first time, after they replaced the names Bopha and Sonamu, which were both retired after the 2012 and 2013 seasons respectively.

### **Philippines**

PAGASA uses its own naming scheme to name tropical cyclones that either develop within or move into their self-defined area of responsibility. The list of names for this season was last used during 2014 and are scheduled to be used again during 2022. All of the names are the same except for Gardo, Josie, Maymay, Rosita and Samuel, which replaced the names Glenda, Jose, Mario, Ruby and Seniang after they were retired. So far, the names Gardo and Josie were used for the first time.

* Basyang (1802)
* Caloy (1803)
* Domeng (1805)
* Ester (1806)
* Gardo (1808)
