The 2017 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 2017, though most tropical cyclones typically develop between May and October. The season's first named storm, Muifa, developed on April 25. The strongest storm so far is Noru, with winds of 150 km/h (90 mph) and a minimum barometric pressure of 955 hPa. This season contained the latest occurrence of the first typhoon of the year since 1998, with Noru reaching this intensity on July 23.

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. 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. PAGASA assigns unofficial names to tropical cyclones which move into or form as a tropical depression in their area of responsibility, located between 115°E–135°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 numerical designation 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 include 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 20, within its seasonal climate outlook for the period January – June.[3] The outlook noted that one to two 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] During March 23, the Hong Kong Observatory predicted that the tropical cyclone season in Hong Kong would be near-normal, with four to seven tropical cyclones coming within 500 km (310 mi) of the territory compared to an average of six.[6] On May 5, Tropical Storm Risk (TSR) issued their first forecast for the season, anticipating an activity of slightly above normal with 27 named storms, 17 typhoons and 10 intense typhoons, including an Accumulated Cyclone Energy (ACE) of 357.[1] On June 26, Taiwan's Central Weather Bureau (CWB) predicted a normal season with 21—25 tropical storms developing over the basin, while three — five systems were expected to affect Taiwan itself.[4] In the same day, the Thai Meteorological Department (TMD) predicted that 2 tropical cyclones would move towards the northern or northeastern parts of Thailand during August or September.[7] On July 6, TSR released their second forecast for the season, reducing the predicted numbers to 25 named storms, 15 typhoons and 7 intense typhoons, with an ACE Index of 250.[2] During the same day, the PAGASA issued their second and final outlook for the season for the period of July – December, where six to nine were expected to develop or entered their area of responsibility between July and September while three to five were forecast during October to December.[8]

Season summary

The first half of the season was relatively inactive, with only seven systems developing, of which only two intensified into tropical storms. The first system of 2017 developed on January 7, and was named Auring by PAGASA. Tropical Depression Bising developed during the first week of February, and was a factor in, and worsened the effects of, the 2017 Visayas and Mindanao floods. This was followed by Crising, the third system unofficially named by PAGASA. Heavy rains from the depression caused flooding that led to the deaths of 10 people in Cebu, Philippines. Shortly after the dissipation of Crising came the formation of the first tropical storm of the season — Muifa. The system was not strong, however, and was located away from all major land areas, so it caused no damage. No systems formed during the month of May, the first such occurrence since 2013. The next cyclone, Merbok, formed during mid-June, and made landfall in Shenzhen in China. The cyclone was short-lived; however, it was relatively strong, producing winds of 100 km/h (65 mph) at its peak. Another weak tropical depression formed at the end of June; however, it dissipated soon afterwards.

Severe Tropical Storm Nanmadol was the next cyclone, and was equal in strength to Merbok. Nanmadol passed over the Ryukyu Islands and progressed to make landfall in Nagasaki on Japan's island of Kyushu. Torrential rainfall and strong winds from the cyclone itself and from the stormy weather that persisted for a number of days were responsible for moderate damage and at least 34 fatalities across mainland Japan. The next two systems were depressions that lasted for slightly longer than the previous unnamed depressions, but caused no notable impacts. Severe Tropical Storm Talas formed during mid-July near the Paracel Islands in the South China Sea, and travelled generally westwards. It made landfall in Vietnam after brushing China's Hainan province and, unusually, continued to track far inland to the Laos-Thailand border before weakening to a depression. At least 14 deaths were attributed to the storm, primarily as a result of flooding.

On January 7, both PAGASA and the JMA reported that Tropical Depression Auring developed about 400 km (250 mi)* to the northeast of Davao City on Mindanao, Philippines.[9][10] During that day, the system moved along the southern periphery of a subtropical ridge of high pressure, before the JTWC initiated advisories on the system and designated it as Tropical Depression 01W.[11] It later made landfall in the Philippines the next day, and was assessed to have degenerated into a remnant low by the JTWC.[12] The JMA however tracked the system until it emerged into the South China Sea.[citation needed] By January 15, the JTWC re-issued advisories as it was located to the east of Vietnam.[13] However, convection dissipated due to wind shear and land interaction, the JTWC issued their final warnings on January 16.[14]

Flooding in Cebu killed one person.[15] Damages from Tropical Depression Auring were totaled at Ph₱7.14 million (US$140,000) from agriculture and fishing in Negros Occidental.[16]

Tropical Depression Bising

Tropical depression (SSHWS)
 
DurationApril 13 – April 20
Peak intensity55 km/h (35 mph) (10-min);
1006 hPa (mbar)

A tropical depression formed over Palau on April 13.[18] During the next 2 days, the system moved toward the Philippines

As of April 17, at least ten people were reported to be killed in Cebu by flooding caused by the system.[19] Total damages throughout the Philippines reached Ph₱84.8 million (US$1.7 million), mostly from Danao, Cebu.[20]

Tropical Storm Muifa (Dante)

Tropical storm (JMA)
Tropical storm (SSHWS)
 
DurationApril 22 – April 29
Peak intensity65 km/h (40 mph) (10-min);
1002 hPa (mbar)

During April 22, the JMA started to monitor a tropical depression that had developed near Guam.[21] After moving westward for a couple of days, the JTWC began issuing advisories, and designated the storm 03W. By April 25, 03W organized and began consolidating further as the JMA upgraded the depression to a tropical storm, giving it the name Muifa.[21] Muifa entered the Philippine Area of Responsibility the following day, and was named Dante by PAGASA.[22] The storm, however, started moving northwards and immediately tracked out of the area by April 27. Following this, both the JMA and the JTWC downgraded Muifa to a tropical depression. Muifa fully dissipated early on April 29, and the JMA issued their final advisory on the storm.[21]

Severe Tropical Storm Merbok

Severe tropical storm (JMA)
Tropical storm (SSHWS)
 
DurationJune 10 – June 13
Peak intensity100 km/h (65 mph) (10-min);
985 hPa (mbar)

On June 10, the JMA started to track a tropical depression to the west of Manila, Philippines.[23] After the system entered a region favorable for further development, the depression rapidly organized, prompting the JTWC to start issuing advisories and give it the designation of 04W. A few hours later, 04W had intensified into a tropical storm, receiving the name Merbok as it start to move in a north-northwestward direction.[23] During June 12, Merbok reached its peak intensity with 10-minute winds of 100 km/h (65 mph) and a minimum pressure of 985 hPa, shortly before making landfall in Eastern Shenzen.[23][24] On June 13, the JMA issued its final warning on Merbok, as the system dissipated over China.[24][23]

Sustained winds of 51.3 knots (95.0 km/h; 59.0 mph) and a minimum pressure of 990.3 hPa (29.24 inHg) were recorded in Hong Kong as the eye passed nearby.[24] Across Guangdong Province, 32 homes were destroyed, 122,000 people reported property damage, and 13,000 hectares of crops flooded. Total economic losses reached CN¥260 million (US$38.2 million).[25]

Severe Tropical Storm Nanmadol (Emong)

Severe tropical storm (JMA)
Tropical storm (SSHWS)
 
DurationJuly 1 – July 5
Peak intensity100 km/h (65 mph) (10-min);
985 hPa (mbar)
Main article: Tropical Storm Nanmadol (2017)

On July 1, the JMA upgraded a low-pressure area it had been monitoring to a tropical depression, located south-southwest of Okinotorishima.[26][27] Later that day, the JMA began issuing advisories once the depression's sustained winds were estimated at 55 km/h (35 mph).[28] Shortly thereafter, the PAGASA classified the system as a tropical depression, assigning the local name Emong. On July 2, the JMA classified the system as a tropical storm, and assigned the official name Nanmadol.[29] The JTWC followed suit and gave the internal designation of 05W. The cyclone continued to intensify, and was upgraded by the JMA to a severe tropical storm later that day.[30] Nanmadol reached peak intensity at about 06:00 UTC on July 3,[31] and maintained this strength until making landfall on the western coast of Kyushu several hours later. The cyclone began to accelerate while following a generally eastward course across the south of Japan. After brushing the southern coast of Japan, the JTWC issued its final advisory during the next day. The JMA followed suit early on July 5, when it had considered the system as extratropical.

Evacuation advisories were issued to at least 20,000 residents due to fears of possible flooding and landslides, especially in the prefectures of Niigata, Toyama and Nagano, which had experienced rainfall accumulations of up to 300 mm (12 in) in the preceding hours.[32][33] At least three people were injured during the storm—a young boy's hand was injured when a school window broke in the city of Kumamoto, and two adults in Oita prefecture sustained minor injuries after falling due to the strong winds.[32][33][34] As of July 13, a total of 30 people have been confirmed dead due to torrential rains which caused landslides and flooding, particularly in Kyushu.[35]

Severe Tropical Storm Talas

Early on July 14, the JMA upgraded a low-pressure area in the South China Sea to a tropical depression after the system began to organize.[36] Late the same day, the JMA began issuing advisories on the depression, and forecast it to develop into a tropical storm within the next 24 hours.[37]

Talas made landfall near Vinh of Nghệ An Province in Central Vietnam at 01:00 ICT on July 17 (18:00 UTC on July 16) as a severe tropical storm.[38] In Vietnam, the storm left 14 people dead and damaged around 2,700 houses. A coal ship with 13 crew members sank off the coast of Cửa Lò, leaving 3 dead and another 3 still unaccounted for.[39] Damages reached nearly 1 trillion₫ (US$43.7 million).[40]

The JMA reported that a non-tropical low had transitioned into a tropical depression north-northwest of Wake Island early on July 19.[41] Fluctuations in intensity ouccred until late on July 29, when explosive intensification ensued.

Tropical Storm Kulap

Tropical storm (JMA)
Tropical storm (SSHWS)
 
DurationJuly 19 – July 26
Peak intensity75 km/h (45 mph) (10-min);
1002 hPa (mbar)

On July 19, the JMA started to monitor a tropical depression that formed over to the southwest of Midway Atoll, just to the west of the International Date Line.[42] The JTWC classified the system as subtropical, however.[43] By July 21, the subtropical storm started to show tropical characteristics, where it prompted both agencies to start issuing advisories, receiving the designation of 09W and the name Kulap.[44] During the next day, Kulap briefly reached its peak intensity with 1-minute sustained winds of 95 km/h (60 mph) after imagery depicted some convection over near its compact center.[45] After moving westward in a marginally favorable environment, the JMA had reported a minimum pressure of 1002 hPa with peak 10-minute winds of 75 km/h (45 mph) during the early hours of July 24. However several hours later, Kulap had entered in a very unfavorable environment such as cooler waters of 25°C (77°F).[46] Due to strong shear and an interaction with Typhoon Noru to its south, Kulap had rapidly weakened; therefore, both agencies issued their final advisory on July 26.[47] The JMA, however, tracked Kulap's remnants a few hours later until it was absorbed by the outflow of Typhoon Noru.

Tropical Storm Sonca

Tropical storm (JMA)
Tropical storm (SSHWS)
 
DurationJuly 21 – July 25
Peak intensity65 km/h (40 mph) (10-min);

On July 21, both the JMA and the JTWC reported that Tropical Depression 08W had developed approximately 582 km (361 mi) to the south of Hong Kong.[48][49] After moving westward for a couple of days, the system strengthened into a tropical storm by both agencies while nearing the island province of Hainan, receiving the name Sonca.[50] By July 24, Sonca reached its maximum intensity with a minimum pressure of 994 hPa.[51] Early on July 25, the JTWC issued its final advisory as the system made landfall over in Quảng Trị Province, Vietnam.[52][53] The JMA issued its final advisory a few hours later until it weakened into an area of low-pressure.

Flooding in Northern Cambodia drowned two people, blocked many roads and flooded several hundred houses.[54]

Heavy rain in Thailand killed an 18 year old in Nakhon Ratchasima in a crash against a roadside tree.[55] One person was also killed in Kut Bak District, Sakhon Nakhon.[56] Damage across Sakon Nakhon exceeded 100 million baht (US$3 million).[57]

Tropical Storm Roke (Fabian)

Tropical storm (JMA)
Tropical storm (SSHWS)
 
DurationJuly 21 – July 23
Peak intensity65 km/h (40 mph) (10-min);
1002 hPa (mbar)

The JMA noted the formation of a tropical depression southeast of Taiwan early on July 21.[58] Assigning the numerical designation 10W, the JTWC upgraded the system to a tropical depression at about 18:00 UTC the same day.[59] The system traveled in a generally northwesterly direction, and passed through the Luzon Strait, between Taiwan and the Philippines.[59] Around the same time, the PAGASA began issuing advisories on the depression, and contributed the unofficial name Fabian. Early the next day, after the system had emerged into the South China Sea, both the JMA and the JTWC upgraded the system to a tropical storm, naming it Roke.[59][60] Roke assumed a more westerly course, and tracked obliquely towards China's Guangdong coast.[61] The JTWC downgraded the system to a tropical depression just 12 hours later, at 18:00 UTC,[59] but the JMA maintained the cyclone's category as a tropical storm. Roke made landfall just east of the Hong Kong central business district at about 01:30 UTC on July 23, and passed over Shenzhen one to two hours later.[61] Roke weakened to a depression a few hours later, at 06:00 UTC.[62]

Schools, businesses and government offices were closed in Hong Kong as the Hong Kong Observatory (HKO) raised its typhoon warning signal to 8—the third highest of ten levels—in preparation for Tropical Storm Roke.[63] Ferry services in the city were suspended, and more than 50 flights were delayed.[64] However, winds in the city were relatively light and no significant damage was reported.

Typhoon Nesat (Gorio)

The JMA upgraded a low-pressure area to a tropical depression east of the Philippines early on July 25.[65]

Despite the storm not making landfall over in the Philippines, Nesat enhanced the southwest monsoon which brought torrential rainfall over most of the country. As of July 30, the NDRRMC had reported a total of Php2.39 million (US$47 thousand) worth of damages.[66]

A low-pressure area over the northern portion of the South China Sea was upgraded to a tropical depression by the JMA early on July 27.[67]

Other systems

On March 20, a tropical depression formed close to the east coast of Leyte, Philippines, and dissipated over the Sibuyan Sea on the next day.[68][69][70] Early on June 29, the JMA initiated advisories on a newly-formed tropical depression south of Okinawa Island.[71] The system re-curved and started moving in a northeastward direction until it dissipated to the southwest of Tokyo on July 1.[72] Early on July 4, the JMA indicated that a tropical depression had formed south of Okinotorishima.[73] During the next day, the JTWC issued a Tropical Cyclone Formation Alert (TCFA) on the system, although it was canceled several hours later.[74] After moving northward, the depression rapidly weakened as it was absorbed by a stationary front on July 7.[75] Early on July 13, the JMA reported that a non-tropical low had transitioned into a tropical depression near Iwo Jima.[76] The depression moved in a generally northeasterly direction until weakening to a low-pressure area by 06:00 UTC on July 16.[77]

A tropical depression formed northeast of Wake Island late on July 25, yet the JTWC indicated a subtropical system.[78]

Storm names

See also: Tropical cyclone naming and History of tropical cyclone naming

Within the Northwest Pacific Ocean, both the Japan Meteorological Agency (JMA) and PAGASA assign names to tropical cyclones that develop in the Western Pacific, which can result in a tropical cyclone having two names.[79] 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)*.[80] PAGASA assigns names to tropical cyclones which move into or form as a tropical depression in their area of responsibility located between 135°E–115°E and between 5°N–25°N even if the cyclone has had an international name assigned to it.[79] The names of significant tropical cyclones are retired, by both PAGASA and the Typhoon Committee.[80] 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

Main article: List of retired Pacific typhoon names

A tropical cyclone is named when it is judged to have 10-minute sustained windspeeds of 65 km/h (40 mph)*.[81] 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.[82] Retired names, if any, will be announced by the WMO in 2018; though replacement names will be announced in 2019. The next 28 names on the naming list are listed here along with their international numeric designation, if they are used.
