These agencies included the Tropical Storm Risk (TSR) Consortium of University College London, PAGASA and Taiwan's Central Weather Bureau.

In late-November, Kammuri formed and became a Category 4 typhoon on the Saffir-Simpson Wind Scale, and made landfall in the Philippines on November 30 causing 17 fatalities and dealing $130 million in damages.

[13] Under high vertical wind shear, the low-pressure area remained disorganized until December 31 when it was upgraded to a tropical depression by both the JMA and the JTWC.

[16] At that time, Pabuk was about 650 km (400 mi) southeast of Ho Chi Minh City, Vietnam and drifted westward slowly with a partially exposed low-level circulation center.

[50] On February 28, Wutip weakened into a tropical depression and lost most of its convection,[51] and was given the name "Betty" by the PAGASA as the storm entered the Philippine Sea.

[53] In Chuuk and Yap States, Wutip produced inundation and powerful winds that destroyed crops and damaged around 160 houses, leaving 165 people homeless.

Early on March 17, the tropical depression entered the PAGASA's area of responsibility in the Philippine Sea, and consequently, the agency assigned the name Chedeng to the storm, shortly before it made landfall on Palau.

Supported by favorable sea surface temperatures and outflow, the system was upgraded to a tropical storm at 09:00 UTC on June 27, gaining the name Sepat.

[83] On July 1, an area of low pressure organized into a tropical depression formed in the South China Sea, near Hainan and the Paracel Islands.

[citation needed] At 12:30 a.m. on July 17 (PST), PAGASA reported that Danas (Falcon) had made landfall at Gattaran, Cagayan and looped over the landmass.

On July 20, around 13:00 UTC, Danas made landfall on North Jeolla Province, South Korea, before weakening into a tropical depression soon afterward.

[citation needed] However, the storm made landfall on Taiwan soon afterward and weakened; as a result, the JTWC cancelled the TCFA and has lowered Goring's chance for development to 'medium'.

[citation needed] The typhoon underwent an eyewall replacement cycle by the following morning, and began to weaken as it did so, as the South China Sea was not favorable for further intensification.

[citation needed] The typhoon brought torrential rain to parts of Shikoku and Honshu, with accumulations peaking at 869.5 mm (34.23 in) at Yanase in Kochi Prefecture.

[citation needed] Although Bailu did not make landfall in the Philippines, two people were killed and a state of calamity was declared in Ilocos Norte due to flooding.

Lingling then made landfall as a Category 4 on Miyako-jima, then continued to intensify, and reaching its peak intensity as a super typhoon, since Lekima a month earlier.

[citation needed] At 2:30 p.m. KST (05:30 UTC), Lingling made landfall in South Hwanghae Province, North Korea with winds of 130 km/h (81 mph),[131] becoming the first typhoon and the strongest storm to strike the country.

[139] Moreover, Lingling's extratropical remnants caused flooding in the Russian Far East, with damage in the Jewish Autonomous Oblast amounting to ₽2 billion (US$30.4 million).

On October 7, while continuing to move west, Hagibis explosively intensified and became a super typhoon in the space of only a few hours, developing a pinhole eye.

[166] Hagibis passed over the Mariana Islands at 15:30 UTC on October 7 at peak intensity, with 10-minute sustained winds of 195 km/h (120 mph) and a central pressure of 915 hPa (27.02 inHg).

[168][169] By 13:30 UTC on October 10, the expected impacts in parts of Japan were such that the organisers of the 2019 Rugby World Cup decided to cancel at least two matches scheduled to be played over the weekend.

Advisories began to be issued on the system as a conducive environment with very warm sea surface temperatures and low wind shear allowed 22W to strengthen.

[183] Matmo destroyed 2,700 houses and 35 schools, causing 3.8 billion VND (US$165 million) in damage in Vietnam, with majority of losses in two provinces: Quảng Ngãi and Bình Định.

[185] On November 2, a well-organized low pressure system rapidly organized into a tropical depression several hundred miles east of the Northern Mariana Islands.

Halong reached its peak intensity as the strongest storm of the 2019 season, with the JTWC estimating 1-minute sustained winds of 305 km/h (190 mph), the highest globally in 2019 and a minimum pressure of 888 hPa (mbar).

[188] On November 9, the Joint Typhoon Warning Center began monitoring a disturbance located in the open waters of the Western Pacific, several hundred miles east of the Mariana Islands.

[citation needed] On November 11, the Joint Typhoon Warning Center began monitoring a disturbance situated only a couple hundred miles off the coast of the Philippines.

Despite initial models suggesting it would be short lived and move towards land, it quickly organized as sea surface temperatures became very conducive for development, and the JTWC issued a tropical cyclone formation alert late on November 11.

Up until November 16, Ramon appeared very disorganised as its low-level circulation center was exposed to high amounts of wind shear and dry air intrusion restricted any strengthening.

[194] Upwelling of itself due to its quasi-stationary movement combined with moderate wind shear hindered significant intensification of Kammuri over the next three days as it moved into the Philippine Area of Responsibility, with PAGASA subsequently assigning the typhoon the name Tisoy.
