Sally slowly weakened as it turned to the northwest and slowed in forward speed, with its winds decreasing to 45 miles per hour (72 km/h) on March 11.

[5] The first typhoon of the season, Tilda originated from a closed circulation on the Intertropical Convergence Zone (ITCZ) south of Truk on April 12.

[2] Tilda attained its peak intensity of 145 mph (233 km/h) 400 miles (640 km) west of Guam on April 19, and it slowly weakened as it turned north-northeast and decreased in forward speed.

Tilda dissipated on April 23 as it merged with the upper-level westerlies 130 miles (210 km) southwest of Iwo Jima, and overall stayed in the open ocean, causing no casualties.

[2] Being the first tropical depression monitored by the Joint Typhoon Warning Center (JTWC),[7] Violet formed offshore Vietnam on June 27.

The system steered northeastward the following day while inland, before entering the East China Sea as an extratropical cyclone on July 8.

[2] Moving to the northwest, it quickly strengthened, reaching tropical storm status, after an eye was found by a recon aircraft.

After peaking at 105 mph (169 km/h) that day, Billie crossed over northeastern Taiwan, quickly weakened, and made landfall on eastern China on July 15.

[13] Storms accompanying Billie and its remnants brought heavy rains and strong winds to South Korea, knocking out police telephone lines in Busan.

On August 4, as Ellen moved northwestward, the storm reached its peak intensity while located 320 km (200 mi) south-southeast of Okinawa, attaining winds of 185 km/h (115 mph).

[17] Ellen dropped up to 35 inches (890 mm) of rainfall on Japan, killing 11 and causing severe rice crop damage.

[2] Ellen's greatest effect, however, was on Taiwan, where torrential rains associated with the typhoon caused disastrous flooding that killed nearly 700, left tens of thousands homeless, and destroyed much of the transportation infrastructure in the central and southwestern part of the island.

The heaviest rain event was on August 7, when as much as 25 inches (640 mm) of rain fell in the mountains and western plains, causing rivers and streams to burst through levees and flood thousands of hectares of farmland, washing away rural villages, and causing widespread urban flooding as well in Taichung and other cities.

The depression continued its journey westward before reaching inland at Hainan on August 19, prior to weakening back into a tropical disturbance.

[2] Moving in a northwest direction, Joan proceeded to rapidly intensify to winds of 315 km/h (195 mph) and deepened to sea-level pressure of 885 hPa (26.13 inHg) on August 29, becoming the 11th most intense tropical cyclone and the most powerful storm of the season.

The mountainous terrain in Taiwan induced a weakening effect on Joan as the storm's center moved above the island, before passing through the Chinese mainland on August 30, before rapidly dissipating inland.

[2] Rainfall from Joan caused several rivers on the Korean peninsula to overflow their banks, killing 17 people and injuring 21.

[30] As Typhoon Joan impacted Taiwan, an elongated low-pressure area from the vicinity of Truk formed along the ITCZ on August 27.

A recon aircraft was sent on August 30, and concluded the existence of a closed surface circulation,[2] assigning the system as Tropical Depression Louise.

[31] As Louise moved farther north, it weakened back to a tropical depression on September 7, before transitioning into an extratropical low, and become embedded with the polar front.

Whilst in the South China Sea on September 10, Tropical Storm Nora took a turn in a northeast direction, before reaching the Chinese coast the following day.

[33] Tropical Depression Opal was short-lived, forming between northeast of Pohnpei and southwest of Ujelang Atoll on September 5, moving west-northwestward before dissipating the next day.

[40] Vera developed on September 20 between Guam and Chuuk State, and initially tracked westward before taking a more northerly course, reaching tropical storm strength the following day.

By this point Vera had assumed a more westerly direction of movement and had begun to rapidly intensify, and reached its peak intensity on September 23 with maximum sustained winds equivalent to that of a modern-day Category 5 hurricane.

[41] With little change in strength, Vera curved and accelerated northward, resulting in a landfall on September 26 near Shionomisaki on Honshu.

Atmospheric wind patterns caused the typhoon to briefly emerge into the Sea of Japan before recurving eastward and moving ashore Honshu for a second time.

[2] Though Vera was accurately forecast and its track into Japan was well anticipated, limited coverage of telecommunications, combined with lack of urgency from Japanese media and the storm's intensity, greatly inhibited potential evacuation and disaster mitigation processes.

Upon moving ashore Honshu, the typhoon brought a strong storm surge that destroyed numerous flood defense systems, inundating coastal regions and sinking ships.

Cooler, drier air weakened the typhoon, and after passing near Okinawa on the 16th it paralleled the southern coast of Japan offshore.

As it paralleled the northeast coast of Luzon, it rapidly intensified to a 135 mph (217 km/h) typhoon, and made landfall on the 16th with slightly weaker winds of 120, the weakening due to land interaction.
