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.

During the year several national meteorological services and scientific agencies forecast how many tropical cyclones, tropical storms, and typhoons will form during a season and/or how many tropical cyclones will affect a particular country. These agencies included the Tropical Storm Risk (TSR) Consortium of University College London, PAGASA and Taiwan's Central Weather Bureau. The first forecast of the year was released by PAGASA during January 15, within its seasonal climate outlook for the period January – June.[3] The outlook noted that one to three tropical cyclones were expected between January and March, while two to four were expected to develop or enter the Philippine Area of Responsibility between April and June.[3] PAGASA also mentioned that the La Niña would be short-lived, predicting that it would last until February or April.[3]

On March 15, the Vietnamese National Center for Hydro Meteorological forecasts (VNCHMF) predicted that roughly twelve to thirteen tropical cyclones would affect Vietnam during 2018, which is above average.[4] On March 23, the Hong Kong Observatory predicted that five to eight tropical cyclones would come within 500 kilometres of Hong Kong, which is normal to above normal, with the first tropical cyclone affecting Hong Kong in June or earlier.[5] On May 11, the Tropical Storm Risk (TSR) issued their first forecast for the season, predicting that the 2018 season would be a slightly above average season producing 27 named storms, 17 typhoons, and nine intense typhoons.[1] The TSR released their second forecast on July 6, still predicting that the season will be an above average with the only changes to their forecast is increasing the number of intense typhoons from 9 to 10.[2] The PAGASA issued their second and final outlook on July 13, predicting for the period of July – December, where six to eight tropical cyclones were expected to develop or entered their area of responsibility between July and September, while four to six were forecast during October to December.

Season summary

Tropical Storm Son-Tinh (2018)Typhoon Maria (2018)Tropical Storm Ewiniar (2018)Tropical Storm Bolaven (2018)

2018 opened with Tropical Depression Agaton active to the east of the Philippines. Over the course of two days, the system moved over to the South China Sea and intensified into the first named storm, Bolaven. A month later, Tropical Storm Sanba developed and affected the southern Philippines. About another month later, Tropical Depression 03W formed in the open Pacific and was named Jelawat. Jelawat intensified into the season's first typhoon on March 30, and then the season's first super typhoon. Tropical activity fired up by June, when a series of storms developed, with Tropical Storm Ewiniar making landfall over mainland China. Later that month, Typhoon Prapiroon developed and affected the Korean Peninsula, the first since 2013. Thereafter, Typhoon Maria developed and reached its peak intensity as a Category 5 super typhoon, being the first typhoon to reach that intensity since Typhoon Nock-ten in 2016.

Tropical Storm Bolaven (Agaton)

Tropical storm (JMA)
Tropical depression (SSHWS)
Bolaven 2018-01-03 0615Z.jpg Bolaven 2018 track.png
Duration December 29, 2017 – January 4, 2018
Peak intensity 65 km/h (40 mph) (10-min)  1002 hPa (mbar)

A low-pressure area developed into a tropical depression northeast of Palau early on December 30, 2017.[7] The system moved generally westward and on the first day of 2018, the PAGASA began issuing advisories on the system and locally named it Agaton.[8] Both the JMA and the JTWC followed suit, with the latter designating the system as 01W.[9] By January 3, the system had intensified into a tropical storm according to the JMA and was named Bolaven, thus becoming the first named storm of the season. However, several hours later, Bolaven started to weaken and rapidly deteriorate.[10] The system was last tracked by the JMA to the east of Vietnam on January 4.

The impact caused by Bolaven (Agaton) was moderate but not as significant as the previous two systems, Kai-tak and Tembin, with about 2,000 passengers stranded in ports in the Visayas.[11] As of July 5, three people have been reported killed by the storm, while total damages were up to 554.7 million pesos (US$10.9 million).[12]

Tropical Storm Sanba (Basyang)

Tropical storm (JMA)
Tropical storm (SSHWS)
Sanba 2018-02-12 0510Z.jpg Sanba 2018 track.png
Duration February 8 – February 16
Peak intensity 65 km/h (40 mph) (10-min)  1000 hPa (mbar)

A low-pressure system developed into a tropical depression north of Chuuk early on February 8. It developed into a tropical storm on February 11, receiving the international name Sanba by the JMA. Shortly afterwards, Sanba entered the Philippine area of responsibility and received the name Basyang by PAGASA.[13] On February 13, Sanba made landfall in Cortes, Philippines,[14] causing it to weaken to a tropical depression. The next day, the system weakened into a remnant low as it made another landfall in Surigao del Sur.[15]

Approximately 17,000 people were affected by the storm and there were 14 fatalities. Total damages were at PHP 167.955 million (US$3.2 million).[16]

Typhoon Jelawat (Caloy)

Typhoon (JMA)
Category 4 super typhoon (SSHWS)
Jelawat 2018-03-30 0550Z.png Jelawat 2018 track.png
Duration March 24 – April 1
Peak intensity 195 km/h (120 mph) (10-min)  915 hPa (mbar)

On March 24, a tropical depression formed to the south of the Mariana Islands,[17] and the JTWC assigned it the numerical identifier 03W.[18] On March 25, the system intensified into a tropical storm and was named Jelawat by the JMA.[19] Due to strong southwesterly wind shear, the cyclone remained poorly organized, with disorganized convection near an exposed low-level circulation.[20] Conditions gradually became more favorable for further development, resulting in Jelawat steadily strengthening and organization to a severe tropical storm at 18:00 UTC on March 28.[21] Later on March 29, an eye began to emerge within a growing central dense overcast, leading to the JMA classifying it as a typhoon at 00:00 UTC on March 29.[22] Explosive intensification then ensued over the following 36 hours as the eye became sharply defined, and Jelawat attained its peak intensity later that morning, with estimated 10-minute sustained winds of 195 km/h (120 mph) and a central pressure of 915 hPa (27.02 inHg).[23] At the same time, the JTWC assessed it as peaking with 1-minute sustained winds of 240 km/h (150 mph), making it a Category 4 super typhoon.[24]

Immediately after peaking in intensity, Jelawat began weakening rapidly, due to a sharp increase in wind shear and dry air, and the storm fell below typhoon strength late on March 31. During the next couple of days, Jelawat drifted to the northeast, and then turned eastward, before dissipating on April 1.

The storm brought minor impacts to Palau, the Caroline Islands, and the Northern Mariana Islands.

Tropical Depression 04W

Tropical depression (JMA)
Tropical storm (SSHWS)
04W 2018-05-12 0345Z.jpg 04W 2018 track.png
Duration May 10 – May 15
Peak intensity 55 km/h (35 mph) (10-min)  1008 hPa (mbar)

A low-pressure area east of Mariana Islands was upgraded to a tropical depression by the JMA late on May 10,[25] shortly before the JTWC issued a TCFA.[26] By May 12, deep convection was observed near its center as the JTWC began issuing advisories on the system giving the designation 04W.[27] Roughly twelve hours later, it was reported that 04W had intensified into a tropical storm by the JTWC after satellite imagery had depicted on a well-defined center.[28] Tracking in a course of a west-northwesterly direction, the system began to weaken as it started entering in an area of unfavorable conditions.[29] Therefore, 04W rapidly weakened as the JTWC issued their final advisory on the system early on May 14, as the system showed a very elongated and exposed center, due to very strong wind shear.[30] The JMA, however, tracked the system until early on May 15, when it finally dissipated.[31]

Tropical Storm Ewiniar

Tropical storm (JMA)
Tropical storm (SSHWS)
Ewiniar 2018-06-06 0525Z.jpg Ewiniar 2018 track.png
Duration June 2 – June 11
Peak intensity 75 km/h (45 mph) (10-min)  998 hPa (mbar)

A low-pressure area developed into a tropical depression over the South China Sea on June 2.[32][33] Later that day the JTWC followed suit and designated the system as 05W.[34] 05W meandered in a westward direction until it curved northward and after three days, the JTWC upgraded the system to a tropical storm.[35] The JMA did the same three hours later early on June 6, naming it Ewiniar.[36] Shortly thereafter, Ewiniar made landfall over South China. Ewiniar maintained its intensity while over land until the JTWC issued its final advisory late on June 7.[37] The JMA, however, tracked the system until early on June 9, when Ewiniar had weakened into a tropical depression and rapidly dissipated.[38]

8 people were killed in China, while total economic losses were estimated at CN¥3.67 billion (US$573 million).[39]

Severe Tropical Storm Maliksi (Domeng)

Severe tropical storm (JMA)
Tropical storm (SSHWS)
Maliksi 2018-06-10 0140Z.jpg Maliksi 2018 track.png
Duration June 3 – June 11
Peak intensity 110 km/h (70 mph) (10-min)  970 hPa (mbar)

A low-pressure area northwest of Palau developed into a tropical depression late on June 3.[40] On the next day, the system received the name Domeng from PAGASA, while the JTWC issued a TCFA for the system.[41][42] After the system had consolidated further, the JMA finally upgraded the system to a tropical storm, naming it Maliksi.[40] The JTWC, however, didn't tracked the system until 03:00 UTC of June 8 when it also gave the designation 06W.[43] Moving northward, Maliksi continued to intensify until it reached its peak strength early on June 10 with winds of 110 km/h (70 mph), just shy of typhoon intensity, and a minimum pressure of 970 hPa.[40][44] Operationally, the JMA briefly classified Maliksi to a typhoon, but was downgraded to a severe tropical storm in post-analysis.[45] Afterwards, Maliksi began to weaken as it begins its extratropical transition. Encounting unfavorable environments by June 11, both agencies immediately stopped warning on the system as the system's center became exposed as the system was declared as an extratropical cyclone.[40][46] The JMA had tracked the remnants of Maliksi until 00:00 UTC of June 13.[40]

Despite not making landfall in the Philippines, Maliksi prompted the PAGASA to declare the official start of the rainy season on June 8, 2018. Two people were killed by heavy monsoonal rains, enhanced by Maliksi, in the Philippines.[47]

Tropical Storm 07W

Tropical storm (SSHWS)
07W 2018-06-13 0525Z.jpg 07W 2018 track.png
Duration June 13 – June 15
Peak intensity 65 km/h (40 mph) (1-min)  993 hPa (mbar)

A disturbance formed southwest of Taiwan on June 12, just within the meiyu front, and the JTWC indicated a subtropical depression subsequently.[48] By 21:00 UTC of June 13, the JTWC issued its first advisory on the system, designating it as 07W, and was classified as a tropical depression.[49] Despite located in a moderately to a severely sheared environment, the system was located over in relatively warm sea-surface temperatures with patches of convection, and this prompted the JTWC to upgrade 07W to a tropical storm.[50] The JTWC later issued their fourth but final advisory on 07W on 15:00 UTC of June 14, when the system was rapidly undergoing a phase of extratropical transition as the system was losing its structure rapidly.[51] 07W fully became an extratropical cyclone just to the south of mainland Japan on 06:00 UTC of June 15, although its remnants was still tracked until June 25, last located near the coast of British Columbia.[48]

Tropical Storm Gaemi (Ester)

Tropical storm (JMA)
Tropical storm (SSHWS)
Gaemi 2018-06-16 0450Z.jpg Gaemi 2018 track.png
Duration June 13 – June 16
Peak intensity 85 km/h (50 mph) (10-min)  990 hPa (mbar)

On June 13, a tropical depression formed on the South China Sea, from Tropical Storm 07W's trough. On June 14, the PAGASA announced it had entered the Philippine Area of Responsibility, assigning the name Ester. Tropical Depression Ester (08W) made landfall by Midnight, intensifying into a Tropical Storm, it was named Gaemi. On June 16, Gaemi became extratropical. June 19, the NDRRMC reported that 3 people had died from monsoonal rains enhanced by Gaemi.[52]

Typhoon Prapiroon (Florita)

Typhoon (JMA)
Category 1 typhoon (SSHWS)
Prapiroon 2018-07-02 0000Z.png Prapiroon 2018 track.png
Duration June 28 – July 4
Peak intensity 120 km/h (75 mph) (10-min)  960 hPa (mbar)

A low-pressure area west of Okinotorishima developed into a tropical depression on June 28. On the next day, PAGASA began issuing advories, giving the name Florita. 6 hours later, Florita became a tropical storm, with JMA assigning Prapiroon for the international name. On June 30, Prapiroon began to intensify into a tropical storm. By July 2, Prapiroon became a Category 1 Typhoon, nearing Japan and Korea. By July 3, Typhoon Prapiroon had peak intensity. On the same day, Prapiroon made landfall on Japan. After landfall, Prapiroon briefly weakened to a tropical storm. On July 4, the JMA and JTWC had reported that Prapiroon has dissipated. [53][54]

Only one person has been killed so far, from South Korea.[55]

Typhoon Maria (Gardo)

Typhoon (JMA)
Category 5 super typhoon (SSHWS)
Maria 2018-07-08 0630Z.png Maria 2018 track.png
Duration July 3 – July 12
Peak intensity 195 km/h (120 mph) (10-min)  915 hPa (mbar)

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.

Other systems

On June 4, the JMA began tracking on a weak tropical depression that had formed northeast of Yap.[62] However, the system was absorbed by a nearby tropical depression, which would eventually become Typhoon Maliksi on the next day.[41] After Gaemi became extratropical, a tropical depression formed south of Hong Kong early on June 17 and dissipated over the east coast of Guangdong, China one day later.[63][64] On July 16, a tropical depression developed over the South China Sea. The system remained weak and moved into Vietnam, before dissipating the next day.

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.[65] 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).[66] 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.[65] The names of significant tropical cyclones are retired, by both PAGASA and the Typhoon Committee.[66] 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).[67] 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.[68] 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 name Ampil was used for the first time, after it had replaced the name Bopha, which was retired after the 2012 season.

Philippines

PAGASA uses its own naming scheme to name tropical cyclones that either develop within or move into their self-defined area of responsibility.[69] The list of names for this season was last used during 2014 and are scheduled to be used again during 2022.[69] 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.[69] So far, the names Gardo and Josie were used for the first time.
