The 1977 Pacific typhoon season was one of the least active Pacific typhoon seasons on record, with only 19 tropical storms forming. It was also the second of the known typhoon seasons during the satellite era (since 1960) to not produce a Category 5 equivalent super typhoon.(After the 1974 season.) The season's first storm, Severe Tropical Storm Patsy, formed on March 23 and the last, Typhoon Mary, dissipated on January 2, 1978. With Mary spanning two calendar years, it became the fourth typhoon to do so since 1945. Since then, two other typhoons have achieved this feat.
The scope of this article is limited to the Pacific Ocean, north of the equator and west of the international date line. Storms that form east of the date line and north of the equator are called hurricanes; see 1977 Pacific hurricane season. Tropical Storms formed in the entire west pacific basin were assigned a name by the Joint Typhoon Warning Center. Tropical depressions in this basin have the "W" suffix added to their number. Tropical depressions that enter or form in the Philippine area of responsibility are assigned a name by the Philippine Atmospheric, Geophysical and Astronomical Services Administration or PAGASA. This can often result in the same storm having two names.
A total of 26 tropical depressions were recognized by the various warning agencies this year in the Western Pacific, of which 20 became tropical storms. Eleven storms reached typhoon intensity, of which one reached super typhoon strength.
A tropical disturbance east of the Philippines organized into a tropical depression on July 21. It moved to the northwest, strengthening into a tropical storm later that day and into a typhoon on the 22nd. After passing northern Luzon and dropping heavy rains, Thelma turned to the north, where it reached a peak intensity of 95 mph winds. The typhoon hit southern Taiwan on the 25th, crossed the island, and dissipated over southeastern China on the 26th. Though not a particularly strong storm, Thelma brought strong wind gusts and heavy rain, claiming more than 30 lives and bringing damage and destruction not seen to the island for over 80 years.
