Systems

25 tropical depressions formed this year in the Western Pacific, of which 21 became tropical storms. 12 storms reached typhoon intensity, of which 3 reached super typhoon strength.

Severe Tropical Storm Wilda (Atring)

|1-min winds=60 Tropical Storm Wilda formed as a disturbance east of the Philippines. It traveled northwest and became a tropical depression as it made landfall on Luzon on June 30. It crossed the island, and became a tropical storm as it entered the South China Sea on 1 July. It traveled north and made landfall in southern China on the 3rd. The remnants of Wilda dissipated inland a few days later.

Typhoon Anita

|1-min winds=70

Typhoon 'Anita' developed over the southern part of the South China Sea and degenerated into a low pressure area over North Vietnam.

Typhoon Billie (Bining)

|1-min winds=130 Tropical Storm Billie, which developed on July 12 east of the Philippines, rapidly strengthened on the 14th and 15th to a 150 mph super typhoon. It tracked due north, fluctuating in intensity for the next 3 days. A building ridge over the Sea of Japan forced Billie to the northwest, where it weakened greatly, first to a tropical storm on the 18th, then to a tropical depression on the 19th as it passed over northeastern China. The storm dissipated on the 20th.

Typhoon Dot

|1-min winds=85 Typhoon Dot struck Hong Kong causing sustained storm force winds, killing one person.

Severe Tropical Storm Clara

|1-min winds=55

Typhoon Ellen

|1-min winds=105 Typhoon Ellen formed as a disturbance on July 16 in the vicinity of Okinotorishima, from a trough in the convergence zone trailing to the southeast of Typhoon Billie the day before.{{cite report| last1=Buckmaster|first1=Albert T.|last2=Atkinson|first2=Gary D.|title=1973 Annual Typhoon Report|url=https://apps.dtic.mil/sti/tr/pdf/ADA399669.pdf|pages=28-29|publisher=Fleet Weather Central/Joint Typhoon Warning Center|location=Guam, Mariana Islands|date=1975-01-01|access-date=2024-06-10}} Its circulation closed up by 17 July, and at 0900 JST (0000 UTC) on the following day, the JMA upgraded it to a tropical storm. Due to its sluggish, erratic movements, Shikoku and Kyushu received heavy rains between July 23 and July 26. This contributed to the above-average monthly precipitation for July 1973 in southern Shikoku and eastern Kyushu, when the rest of Japan was suffering from droughts.

Tropical Storm Fran (Kuring)

|1-min winds=40

Typhoon Georgia

|1-min winds=70

Typhoon Iris (Daling)

|1-min winds=85 Iris struck North Korea and Japan.

Tropical Storm Hope

|1-min winds=45

Tropical Depression 11W

|1-min winds=30

Tropical Storm Joan (Elang)

|1-min winds=45

Severe Tropical Storm Kate (Goring)

|1-min winds=60

Tropical Depression 14W

|1-min winds=30

Typhoon Louise (Huling)

|1-min winds=75

Typhoon Marge (Ibiang)

|1-min winds=80

Hainan, Qionghai Jiaji town recorded a minimum central pressure of 937.8 hPa when Marge made landfall. Marge killed 903 people in Hainan. Marge made its final landfall in Tam Diep Mountains (border of Ninh Binh and Thanh Hoa provinces) Vietnam in late September 14, 1973; brought heavay rainfall and flooding in North Vietnam.

Typhoon Nora (Luming)

|1-min winds=160 Main article: Typhoon Nora (1973)

The monsoon trough spawned a tropical depression east of the Philippines on October 1. Under weak steering currents, it meandered westward, where favorable conditions allowed for it to strengthen, first to a tropical storm on the 2nd, then to a typhoon on the 3rd. Nora continued to the northwest, and explosively deepened on the 5th and 6th to a 185 mph super typhoon. At the time, it had a minimum central pressure of 875 millibars, the lowest pressure on record at the time and currently tied for 9th. The typhoon weakened as it headed to the northwest, and struck northeastern Luzon on the 7th as a 115 mph typhoon. Nora continued to the northwest, weakening to a minimal typhoon as it hit southeast China on the 10th. The typhoon caused 18 fatalities, with over $2 million in damage.

Typhoon Opal

|1-min winds=75

Typhoon Patsy (Miling)

|1-min winds=140

Typhoon Ruth (Narsing)

|1-min winds=90 27 people were killed when Typhoon Ruth crossed Luzon on October 15 and caused $5 million in damage. Ruth continued to the northwest, and hit Hainan Island and Quang Ninh, Vietnam on the 19th, respectively.

Severe Tropical Storm Sarah

|1-min winds=55 On November 12 this system emerged in the Bay of Bengal and became Tropical Storm Thirteen (13B)

Severe Tropical Storm Thelma

|1-min winds=55

Severe Tropical Storm Vera (Openg)

|1-min winds=50 One of the strongest tropical cyclones to hit Visayas when it entered on November 20, although the system didn't reach typhoon status. Tropical Storm Openg affected around 3.4 million people.

Storm names

Western North Pacific tropical cyclones were named by the Joint Typhoon Warning Center. The first storm of 1973 was named Wilda and the final one was named Vera.

Philippines

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 10 of which are published each year before the season starts. This is the same list used for the 1969 season. 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.).

Season effects

This table will list all the storms that developed in the northwestern Pacific Ocean west of the International Date Line and north of the equator during 1973. It will include their intensity, duration, name, areas affected, deaths, missing persons (in parentheses), and damage totals. Classification and intensity values will be based on estimations conducted by the JMA, however due to lack of information around this time sustained winds were recorded by the JTWC. All damage figures will be in 1973 USD. Damages and deaths from a storm will include when the storm was a precursor wave or an extratropical low.
