[31] At noon on May 21, the center of Tess passed 160 km (99 mi) west of Marcus Island,[12]: 74 bringing squalls accompanied by heavy rain and winds of 90 km/h (56 mph).
Winnie weakened to a tropical storm and traversed Hainan and the Gulf of Tonkin before making a final landfall near Haiphong, Vietnam, on July 3.
[46][58] Manila was placed under a state of emergency following Winnie, with government agencies deploying medical and rescue teams to affected areas amid widespread power outages.
[62][12]: 75 The disturbance that led to Typhoon Betty was first detected in the Philippine Sea on July 1 by the JTWC, having developed from a segment of a polar trough within an area of conducive winds in the upper-troposphere.
[12]: 75 Betty's winds subsequently began to diminish precipitously while the storm curved towards the north and then north-northeast, briefly paralleling the coast of Zhejiang before entering the Yellow Sea.
An analysis of the historical tropical cyclone record for the West Pacific published in the Monthly Weather Review concluded that there was "sufficient evidence" that the winds in storms like Cora were "likely overestimated.
"[67] The Royal Observatory Hong Kong analyzed a substantially lower pressure of 920 hPa (mbar; 27.17 inHg) at the time of Cora's peak strength.
[66] As Cora neared northern Samar and southern Luzon on July 9, its forward motion slowed and its winds unexpectedly diminished and fell below the typhoon threshold.
[68][12]: 75 Storm warnings were issued in southeastern Luzon with Cora 100 km (62 mi) east of Samar, with forecasts projecting stormy conditions in the region and in other islands in the east-central Philippines.
[72] Elsie emerged from a detached portion of a polar trough on July 13 near the Northern Mariana Islands; this developed into a tropical depression later that day.
[85] Helen began within a region of sparse weather observations east of the Northern Mariana Islands on July 27, starting with a northward track that curved towards the northwest.
Naval Base Subic Bay were evacuated into the South China Sea prior to the storm's arrival and people in low-lying fishing villages left for higher ground.
[22][115][6]: 63 However, data from the CMA and JMA indicates that June persisted as a tropical depression into the South China Sea and took a looping course near Hainan and the Leizhou Peninsula.
[120][6]: 146 The storm's west-southwest path brought the center across the Ryukyu Islands and near Okinawa on August 16 as Kathy began to execute a counterclockwise loop in its track.
On August 23, Kathy made landfall on Kagoshima Prefecture with winds of 130 km/h (81 mph) and weakened to a tropical storm as it crossed the Seto Inland Sea and southern Honshu.
[133] The combination of converging low-level winds and divergence in the upper troposphere over the Philippine Sea led to the environmental conditions that resulted in the formation of Typhoon Marie.
The storm then weakened and curved towards the west; the JTWC determine Marie to have been absorbed by Typhoon Kathy approximately 240 km (150 mi) north of Okinawa on August 18.
[134][12]: 76 [6]: 155 However, the CMA and JMA assessed Marie to have remained intact, continuing on a curved path towards the south and then east, bringing it around Okinawa as a tropical cyclone until its dissipation on August 20.
[168] The JTWC recognized the storm as a tropical cyclone on September 19 when it was located roughly 370 km (230 mi) northwest of Saipan, and assessed Wilda to have strengthened into a typhoon later that day.
Wilda made a final landfall on the western coast of northern Honshu on September 25 as a tropical storm, thereafter departing Japan and quickly moving towards the central Aleutian Islands as a powerful extratropical cyclone.
Billie had already begun to weaken on approach to land but diminished further once over Southeast Asia; the storm and its remnants continued tracking west into Myanmar before dissipating on October 3.
The storm weakened within the Gulf of Tonkin and struck Vietnam north of Đồng Hới on October 8 with one-minute sustained winds estimated at 85 km/h (53 mph) by the JTWC.
[192][12]: 77 The storm continued to strengthen once it emerged into the South China Sea, and reached its peak intensity with one-minute sustained winds of approximately 165 km/h (103 mph) on October 11.
Fran then took a more northward heading, and only October 17 attained peak one-minute sustained winds of 95 km/h (59 mph) approximately 650 km (400 mi) west of Wake Island according to the JTWC.
At around 06:00 UTC on October 21, Georgia made landfall on Luzon at Lamon Bay and passed north of Manila; one-minute sustained winds associated with the storm at the time were around 65 km/h (40 mph).
[12]: 77 This intensification was attributed to the instrusion of colder air into the typhoon's circulation, causing a surge of winds in the lower levels of the atmosphere during a relatively short timeframe.
Early the next day, a reconnaissance plane recorded a pressure of 1000 mbar (hPa), the lowest in relation to Joan; however, this was measured while the system was a minimal tropical storm.
[214][213][12]: 78 Louise continued to intensify after passing the island, and attained its peak intensity on November 18 with one-minute sustained winds of 305 km/h (190 mph) and a central air pressure of 915 hPa (mbar; 27.09 inHg).
[12][223][224][225] A state of calamity was declared for Surigao del Norte,[226][227] prompting an intense relief effort amid an ongoing cholera epidemic and unrelated flooding.
[233] Rough waters kicked up by the storm led to the sinking of a cargo ship near Zamboanga City, causing the presumed drownings of 18 people; another 37 crewmembers were rescued.
