Eleven typhoons reached winds of at least 135 knots. They were Isa, Nestor, Rosie, Winnie, Bing, Oliwa (from Central Pacific), Ginger, Ivan, Joan, Keith, and Paka (also from the Central Pacific).

of 1997–1998, which contributed to the record amounts of not only super typhoons but also tropical storms in the Western and Eastern Pacific. Fortunately, most of the stronger systems remained at sea. This is also due to the El Nino during that time, which tends to shift typhoon tracks east.
When Severe Tropical Storm Peter made landfall in southern Japan on June 27, it marked the first time that two tropical cyclones made landfall in mainland Japan during the month of June since reliable records began in 1951.

to its northwest forced the depression southeastward. It became steadily less organized, and on July 26 JTWC issued a final warning on the system, believing it to be dissipating. Shortly thereafter, however, the system began re-organizing, and on July 27 the system developed into Tropical Storm Scott. The storm tracked northwestward, then westward, and finally turned to the northeast. Scott gradually strengthened to attain peak winds of 105 km/h (65 mph) on July 29.
JMA had upgraded the depression to tropical storm status on July 28, and assessed its peak intensity at 75 km/h (45 mph).
Scott maintained its peak intensity for about 12 hours before slowly weakening as it accelerated northeastward. On August 2, the storm merged with an approaching
frontal trough,
and the following day JMA considered Scott dissipated while located near the Alaskan island of
Gareloi.
Tropical Storm Scott never affected land.

Intensification became more rapid as conditions became more favorable, and Winnie reached typhoon strength on the 10th. Two days later, Winnie became the 4th Super Typhoon of the season with peak winds of 160 mph. Soon after, the eye became ragged and large, with an outer eyewall reaching 200 miles in diameter. On the 18th, a minimal Typhoon Winnie passed north of

Severe Tropical Storm Yule
Severe Tropical Storm Yule merged with Tropical Depression 16W early in its life.
Tropical Depression 16W
Tropical Depression 16W developed out of a weak tropical disturbance on August 13. The disturbance was relatively close to another disturbance which would eventually become Severe Tropical storm Yule. By August 17, the disturbance had developed sufficient convection to be declared a tropical depression. However, upon being classified a depression, it was already beginning to be influenced by the nearby Yule. 16W eventually was overcome by Yule and a merger of the two systems took place on August 19, leading to the dissipation of the depression.
Severe Tropical Storm Zita (Luming)
Originating from a tropical disturbance over the South China Sea on August 19, Zita tracked westward as it quickly strengthened within a region of light wind shear, attaining winds of 140 km/h (85 mph) as it made landfall along the Leizhou Peninsula early on August 22. Maintaining this intensity, the storm made a second landfall in northern Vietnam later that day before rapidly weakening over land. The remnants of Zita were last noted over extreme northwestern Vietnam on August 24.
Early in its existence, the storm was monitored by PAGASA and was designated with the local name Luming.
Throughout Zita's path, seven people were killed and $438 million was wrought in damage, nearly all of which took place in China.

In Japan, severe flooding from the typhoon killed 12 people and displaced 30,000 others. 10 people were reported missing but are possibly dead.

Tracking in a more northerly direction, the depression intensified into a tropical storm the next day, at which time it was given the name Ginger. Continued strengthening occurred at a climatological rate until it was upgraded to a typhoon on September 25. Upon becoming a typhoon, Ginger underwent a period of
explosive development.
During this period, the storm intensified into a

Tropical Depression Hank
Tropical Storm Hank originated out of an area of low pressure over the South China Sea in late September. Minimal convection was associated with the system and only light winds were recorded. Over the following days, the system gradually organized and by October 3, the JTWC issued a TCFA for the system. However, in post-storm analysis, it was found that Hank was already a tropical storm by this time. By the time the TCFA was issued, Hank reached its peak intensity with winds of 75 km/h (45 mph) before succumbing to strong wind shear. Late on October 3, Hank weakened to a tropical depression and was initially thought to have made landfall; however, satellite analysis showed that the center did not cross land until October 5, shortly before dissipating. There were no reports of damage in relation to the storm.

Typhoon Ivan (Narsing)
Forming out of an area of disturbed weather on October 13, Ivan gradually intensified into a typhoon as it tracked steadily to the west-northwest. On October 15, the storm underwent rapid intensification and reached an intensity corresponding to Category 5 status on the Saffir–Simpson hurricane scale. Late on October 17, Ivan reached its peak strength with winds of 295 km/h (185 mph) and a barometric pressure of 905 hPa (mbar). Shortly thereafter, the typhoon began to weaken as it approached the Philippines. Ivan eventually made landfall in northern Luzon with winds of 220 km/h (140 mph) on October 20 before weakening to a tropical storm the next day. The storm then curved northeastward and became extratropical on October 25, dissipating the following day.
During its existence, Ivan was monitored by PAGASA and designated with the local name Narsing.
Although Ivan was a powerful storm at landfall, its effects were relatively minor compared to the storm's intensity; however, 14 people were killed during the storm and two others were listed as missing. Agricultural industries sustained the most severe damage, as thousands of animals drowned in the storm. Throughout the Philippines, damage amounted to $9.6 million (1997 USD; $13.1 million 2009 USD). A total of 1,779 homes were destroyed, 13,771 others were damaged and 4,600 hectares of farmland were flooded by the storm.
