These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean.

The scope of this article is limited to the Pacific Ocean, north of the equator and west of the International Date Line.

Tropical storms formed in the entire west Pacific basin were assigned a name by the Fleet Weather Center on Guam.

Later that day, the storm attained its peak intensity with winds of 45 mph (72 km/h)[3] and a barometric pressure of 995 millibars (29.4 inHg).

The system made landfall in eastern Leyte early on January 6 with winds of 35 mph (56 km/h) before dissipating the following day over Romblon.

Rose maintained this intensity for roughly 24 hours before undergoing a brief period of rapid intensification, attaining winds of 110 mph (180 km/h) early on January 23.

For most of the day, the now Category 2 typhoon, strengthened at a more modest rate before undergoing a second brief period of rapid intensification.

At the end of the second strengthening phase, Rose had attained its peak intensity just below Category 5 status, on the modern-day Saffir–Simpson Hurricane Scale, with winds of 155 mph (249 km/h),[5] and a minimum pressure of 952 millibars (28.1 inHg).

The JTWC continued to monitor the weakening tropical storm until January 27, by which time Rose had maximum winds of 40 mph (64 km/h).

[7] According to the International Best Track Archive for Climate Stewardship, Wendy originated from a tropical depression well east of the Philippines on July 10.

Further intensification occurred, and around 15:00 UTC on July 14, Wendy peaked with sustained winds of 90 knots (100 mph) and a minimum pressure of 985 hPa.

Although it temporarily reintensified, attaining a secondary peak with sustained winds of 80 knots (90 mph) around that time, it began rapidly weakening, making its final landfall in Guangdong, China as a high-end tropical storm.

Striking the island with gusts of 95 knots (110 mph) and torrential rainfall, the typhoon killed sixteen and injured a further two hundred.

The SS Tweed Breeze broke from its buoy and ran aground in Stonecutter's Island, while parts of Taipo Road became inaccessible due to collapsing.

Elsewhere, in China's Guangdong Province, over three hundred-thousand people were mobilized to gather crops and take safety precautions due to the storm.

Agnes then began to curve towards the north, passing over one of the Ryukyu Islands with 155 mph winds and a minimum central pressure of 905 mbar.

On August 21, South Korea was struck by a 50 mph Agnes; their 1st[clarification needed] tropical cyclone of the season.

It moved in a generally westward direction for a couple days until it struck Hainan on August 18 with 65 mph winds and a minimum pressure of 984 mbar.

On August 30, the typhoon battered the United States military base on Iwo Jima with winds of 110 mph (180 km/h), resulting in communication loss for roughly 23 hours.

[20] Widespread damage took place throughout Kyushu as wind gusts up to 115 mph (185 km/h) and torrential rains impacted the region.

[23] According to police reports, 912 homes were destroyed and 1,522 others were severely damaged by flooding and landslides triggered by Typhoon Bess.

During its long northwestward trek, Della reached its peak intensity of 140 mph and a minimum central pressure of ≤960 mbar.

Faye also left damages, straining the expensive budget caused by past and future typhoons that struck the island.

At first, it slowly intensified, then rapid intensification occurred, reaching its peak strength of 150 mph while southeast of Japan.

The tropical cyclone strengthened to a category one typhoon with maximum sustained winds of 85 mph and a minimum central pressure 990 mbar.

Typhoon Irma brought torrential rains and high winds to Vietnam, resulting in nine fatalities and an estimated $2 million in damage.

It moved westward and strengthened into a super typhoon with maximum sustained winds of 150 mph and a minimum central pressure of 960 mbar.

It briefly became a category five super typhoon with maximum sustained winds of 160 mph and a minimum central pressure of 910 mbar.

[32] On November 17, Tropical Storm Mamie developed over the open Pacific Ocean, in a way similar to Typhoon Lola's formation, but moved northwest instead.

As soon as Mamie began to curved north, it attained its maximum sustained winds of 125 mph and minimum central pressure of 960 mbar.
