Tropical storm (SSHWS)
Duration	April 5 (Entered basin) – April 7 (Exited basin)
Peak intensity	110 km/h (70 mph) (10-min); 985 hPa (mbar)

On April 4, a tropical depression formed just east of the International Date Line.[1] At the time, the Joint Typhoon Warning Center (JTWC) designated it tropical depression 02W. As it moved generally northwestwards, it strengthened into a tropical storm just before crossing the dateline, but only received a name in the northwest Pacific, being designated Carmen.[1] After peaking with maximum sustained winds of 70 mph (110 km/h) on April 6,Carmen recurved northeast and crossed the International Date Line, entering the central Pacific on April 7.[1] The JTWC subsequently relinquished responsibility to the Central Pacific Hurricane Center. Carmen lost its initial motion and stalled in the area, ultimately weakening in to a tropical depression on April 8.[1] The depression dissipated the following day and the remnant low returned to western Pacific.[1]

Typhoon Joe, which developed on July 16 from the near equatorial trough, hit eastern Luzon on the 20th. It weakened over island, but restrengthened in the South China Sea to a 100 mph typhoon before making landfall on Hainan Island on the 22nd. Joe made its final landfall that night on northern Vietnam before dissipating on the 23rd. Joe caused heavy damage and an estimated 19 deaths in the Philippines with many more in Vietnam. The exact numbers are unknown due to Typhoon Kim hitting just four days later.

Tropical depression (JMA)

Like Typhoon Joe, Kim formed from the near equatorial monsoon trough on July 19. It tracked quickly westward-northwest underneath a subtropical ridge, reaching tropical storm strength on the July 21 and typhoon strength on July 23. After developing an eye, Kim began to rapidly intensify, and during the afternoon of July 24, peaked in intensity as a super typhoon. Several hours later, Kim made landfall over the Philippines, but the storm had weakened considerably by this time. Throughout the Philippines, 40 people were killed, two via drownings, and 19,000 others were directly affected. A total of 12,000 homes were destroyed and 5,000 villages received flooded. Less than a week earlier, the same areas were affected by Joe; however, Kim was considered the more damaging of the two typhoons. Land interaction took toll on Kim, and upon entering the South China Sea, was down below typhoon intensity. Kim continued northwestward, but with its disrupted circulation, it remained a tropical storm until hitting southern China July 27 to the northeast of Hong Kong, where damage was minor. Later that day, Kim dissipated.

Peak intensity	130 km/h (80 mph) (10-min); 960 hPa (mbar)

The monsoon trough spawned a tropical depression on September 1. It tracked northwestward, remaining disorganized and dissipating on the 5th. Another tropical depression developed to the east of the old circulation, quickly becoming the primary circulation and intensifying to a tropical storm on the 6th. With generally weak steering currents, Orchid looped three times on its track, strengthening to a typhoon on the 9th and reaching a peak of 95 mph winds on the 10th. Early on the 11th the storm hit southwestern Japan, and became extratropical that day over the Japan Sea. Orchid caused considerable damage from high winds and rain, resulting in at least nine casualties with 112 missing. It was also responsible for the September 10th loss of the MV Derbyshire, a large 91,655 ton bulk carrier which sank on 9 September with all 44 hands on board due to very rough seas. It remains the largest British flagged ship to be lost at sea.

A tropical disturbance was first observed near Yap on the 14th of December. The disturbance moved westward at between 12 and 15 kt (22 to 28 km/h) as its convective activity and overall organization continued to improve. A Tropical Cyclone Formation Alert (TCFA) was issued when a reconnaissance aircraft observed a well-defined low-level circulation with a minimum sea-level pressure of 1004 mb. The disturbance was upgraded to Tropical Storm Ed on December 15. It then became evident from synoptic analyses that Ed was moving into an area which was unfavorable for continued development. Eventually, after most of the storm's convection had been sheared off, Ed's surface center began to track to the southwest under the influence of the strong surface ridge to the north. Dissipation as a tropical cyclone was completed on the 24th as the remnants of Ed moved into northern Mindanao.

The Philippine Atmospheric, Geophysical and Astronomical Services Administration uses its own naming scheme for tropical cyclones in their area of responsibility. PAGASA assigns names to tropical depressions that form within their area of responsibility and any tropical cyclone that might move into their area of responsibility. Should the list of names for a given year prove to be insufficient, names are taken from an auxiliary list, the first 6 of which are published each year before the season starts. Names not retired from this list will be used again in the 1984 season. This is the same list used for the 1976 season, with the exception of Ditang, which replaced Didang. PAGASA uses its own naming scheme that starts in the Filipino alphabet, with names of Filipino female names ending with "ng" (A, B, K, D, etc.). Names that were not assigned/going to use are marked in gray.
