Storms
32 tropical depressions formed this year in the Western Pacific, of which 28 became tropical storms. 15 storms reached typhoon intensity, of which 1 reached super typhoon strength. Many of the storms either remained at sea or failed to do any damage.

Tropical Storm Nadine
Early in 1978, a tropical disturbance formed north of the island of Tarawa. The disturbance slowly organized itself and became a tropical depression late on January 6 while southwest of Kwajalein Atoll. On January 8, the tropical depression made a sharp curve to the east and then to the west as it organized into the first tropical storm of the season and was named Nadine while the system was southwest of Eniwetok Atoll. Nadine began it's re-curvature on January 11 as it continued to gather strength. Nadine reached it's peak strength of 70 mph (112 km/h) during the afternoon hours of January 12 as it sped past Wake Island. Early on January 13, Nadine became extratropical. The extratropical remnants dissipated later that same day as they continued to speed north.

Typhoon Olive (Atang)
During early April 1978, a surface circulation was noted in the near-equatorial-trough. Weak anti-cyclonic outflow was first noted near the surface circulation during the 13 th and persisted for the next two days. By April 16, the satellite imagery showed organization and a tropical cyclone formation alert was issued. Early on April 17, the system which was still poorly defined strengthened into the second tropical depression of the season. On the 18 th, an aircraft fix found that the system was near tropical storm strength and had a pressure of 1001 mbar (hPa) 29.56 inches). Later that same day, the tropical depression was upgraded to a tropical storm and named Olive. The system continued to strengthen as it traveled westward, toward the Philippines. On April 20, Olive passed through the Leyte Gulf with winds of 70 mph (112 km/h). As Olive crossed the central Philippines, it weakened to have winds of 50  mph (80 km/h) .  Upper level outflow remained good and Olive exited the Philippines and emerged into the South China Sea late on the 20 th . Olive quickly strengthened in the warm waters of the tropical sea and reached typhoon intensity early on April 22. Olive reached it's peak intensity of 100 mph (160 km/h) on April 23 and retained that intensity for 36 hours. After losing peak strength late on April 24 north of the island of Luzon, Olive rapidly lost strength  as it traveled over cooler waters. Olive became extratropical in the cold waters in the Central-West-North Pacific late on April 26. The extratropical cyclone dissipated the next day while southwest of Iwo Jima (Iwo To). Any impact that Olive had on the Philippines is unknown.

Tropical Storm Polly (Bising)
On June 13, a tropical disturbance formed southwest of Iwo Jima (Iwo To). It quickly organized and early on June 14, the JTWC designated the disturbance as a tropical depression. After heading northward for the rest of the day, it reversed its course and began to head southward early on June 15. After looping the next day it continued on a northwest course until June 18. It then looped again and finally strengthened into a tropical storm and named Polly. The storm was now strengthening and heading northward to begin its re-curvature. On June 19, just as the storm was nearing the Japanese coast, it reached its peak intensity of 60 mph (95 km/h). A slightly weaker storm made landfall on the Japanese island of Kyushu the next day and quickly became extratropical. As an extratropical cyclone, it was tracked to near the International Date Line. Any damage from Polly in Japan is unknown.

Tropical Storm Agnes
Agnes formed on July 24, made a complete loop, and struck China on July 29 with winds of 55 mph after peaking at 60 mph. It dissipated the 30th. In Hong Kong Tropical Storm Agnes killed 3 people.

Super Typhoon Rita (Kading)
Tropical Depression 28 developed October 15. Three and a half days later, it strengthened into a tropical storm. Rita became a typhoon late on October 19. Rita reached Category 5 status on October 23, reaching a minimum central pressure of 878 millibars, only 8 mb higher than Typhoon Tip's record set in 1979. After spending over three consecutive days at that intensity, Rita weakened to a Category 4 and smashed ashore on Luzon. Rita stayed a typhoon during its entire passage over the Philippines and emerged into the South China Sea as a minimal typhoon. Rita then decayed slowly and dissipated as a depression near the coast of Vietnam. The typhoon caused considerable damage and loss of life in the Philippines, though exact numbers are unknown.

JMA Tropical Storm 27
This storm was only monitered by JMA.

Tropical Storm Winnie
Winnie formed on November 25. It reached a peak of 65 mph winds before its end on November 30.
