The '''1980 Pacific typhoon season''' was a slightly-below average season when compared to the long-term average, though it featured several intense storms. It ran year-round in 1980, but most [[tropical cyclones]] formed between June and December. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean. A total of 28 tropical depressions formed this year in the Western Pacific, of which 24 became tropical storms and were assigned a name by the [[Joint Typhoon Warning Center]]. Beginning in March, tropical cyclones formed in each subsequent month through December. Of the 24 named storms, 15 storms reached typhoon intensity, of which 2 reached super typhoon strength. 

Additionally, 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. This year, 23 storms were named this way.

On 5 May, a weak tropical disturbance began developing in the near-equatorial trough. As it tracked westward across the [[Caroline Islands]] in the following three days, little development was seen.<ref name="DomJTWC">{{Cite report |url=https://www.metoc.navy.mil/jtwc/products/atcr/1980atcr.pdf |title=1980 Annual Tropical Cyclone Report |date=1981 |publisher=[[Joint Typhoon Warning Center]] |location=Guam, Mariana Islands |page=28-29 |access-date=July 15, 2024}}</ref> Despite that, on May 7, the [[Japan Meteorological Agency]] designated the disturbance as a tropical depression.<ref name="JMABT">{{Cite report |title=RSMC Best Track Data – 1980–1989 |date= |url=https://www.jma.go.jp/jma/jma-eng/jma-center/rsmc-hp-pub-eg/Besttracks/bst8089.txt |access-date=2024-07-20 |url-status= |publisher=Japan Meteorological Agency |location=Tokyo, Japan |archive-url=https://web.archive.org/web/20110723110117/https://www.jma.go.jp/jma/jma-eng/jma-center/rsmc-hp-pub-eg/Besttracks/bst8089.txt |archive-date=2011-07-23}}</ref> The next day, an uptick in convective activity prompted the JTWC to issue a TCFA on the system, which was south of Guam. As the circulation steadily organized, the JTWC upgraded the system into a tropical depression.<ref name="DomJTWC" /> Two days later, the depression crossed into the [[Philippine Area of Responsibility]] (PAR), causing the [[Philippine Atmospheric, Geophysical, and Astronomical Services Administration]] (PAGASA) to name it ''Ditang''.<ref name="T2000" /> Despite intense vertical shear, the depression intensified into a tropical storm a few hours later, being named ''Dom'' by the JTWC.<ref name="DomJTWC" /> After the wind shear relaxed, on May 11, the JTWC stated that Dom had intensified into a typhoon, with the JMA following suit the next day.<ref name="DomJTWC" /><ref name="JMABT" /> Soon after, Dom began weakening due to the mountainous terrain of Luzon, becoming a tropical storm on May 14. However, as Dom traced eastward, the next day, it re-intensified into a typhoon.<ref name="DomJTWC" />

After this secondary peak, a combination of colder SSTs and unfavorable atmospheric conditions caused the system to steadily weaken, and after doing an anticyclonic loop, on May 18, Dom weakened into a tropical storm. The next day, the JTWC issued their last advisory on Dom, declaring that it had degenerated into a post-tropical cyclone.<ref name="DomJTWC" /> PAGASA kept tracking the system until May 21,<ref name="T2000" /> when the remnants of Dom and a weakening Ellen began accelerating towards an [[extratropical cyclone]] south of Japan.<ref name="DomJTWC" /> The remnants of Dom and Ellen later merged with the cyclone the same day,<ref name="DomJTWC" /> causing the JMA to finally stop monitoring Dom a few hours later.<ref name="JMABT" /> 

As Ditang tracked towards the Philippines, PAGASA issued [[Public Storm Warning Signal]] (PSWS) #3 for [[Catanduanes]], [[Camarines Norte]] and [[Camarines Sur|Sur]], [[Aurora (province)|Aurora]], [[Quirino]], [[Cagayan]], [[Mountain Province]], [[Nueva Vizcaya]], [[Ifugao]], [[Batanes]], and [[Abra (province)|Abra]].

On 11 May, a tropical disturbance located in an equatorial trough east of [[Chuuk Lagoon]] began developing.

As Ellen made its closest approach to Japan, [[Yokosuka]] saw gusts of {{cvt|30-35|knot|mph km/h}}.<ref name="JMABT" /> Heavy rainfall from Ellen affected western and central Japan, causing around 60 landslides and flooding almost 300 homes.<ref name="IJMET" />

In mid-June, an equatorial trough was active, stretching from the Philippines to the eastern Caroline Islands near the equator. On 20 June, satellite imagery indicated increased convective activity around the eastern periphery of the trough as a result of convergent easterly
flow.

The depression began to develop at a quicker pace, and early on July&nbsp;18, the JTWC upgraded it to a tropical storm.<ref name="JTWC ATCR" /> After Joe developed a [[central dense overcast]], the JMA upgraded Joe into a severe tropical storm.<ref name="JMABT" /> At midday, the JTWC and JMA upgraded Joe into a typhoon.<ref name="JMABT" /><ref name="JTWC ATCR" /> This intensity estimate was confirmed by a Hurricane hunter plane later on July&nbsp;19, which measured a pressure of {{convert|974|mbar|inHg|abbr=on}}.

At midday, the JTWC estimated that Joe peaked in intensity, with winds of {{convert|120|mph|km/h|abbr=on|round=5|order=flip}}, equal to a Category&nbsp;3 hurricane on the United States-based [[Saffir-Simpson Hurricane Wind Scale]] (SSHWS).

}} A tropical disturbance was first observed near Yap on 14 December. The disturbance moved westward at between 12 and 15 kt (22 to 28&nbsp;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.

== Storm names ==
{{See also|Lists of tropical cyclone names|Tropical cyclone naming}}
During the season 24 named tropical cyclones developed in the Western Pacific and were named by the Joint Typhoon Warning Center, when it was determined that they had become tropical storms. These names were contributed to a revised list which started in 1979.

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 Pacific typhoon season|1984 season]]. This is the same list used for the [[1976 Pacific typhoon season|1976 season]], with the exception of ''Ditang'', which replaced ''[[1976 Pacific typhoon season#Typhoon Olga (Didang)|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 {{tcname unused}}.

== 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 1980. It will include their intensity, duration, name, areas affected, deaths, and damage totals. Classification and intensity values will be based on estimations conducted by the JMA, the JTWC, and/or PAGASA. Peak wind speeds are in ten-minute sustained standards unless otherwise noted. All damage figures will be in 1981&nbsp;USD. Damages and deaths from a storm will include when the storm was a precursor wave or an extratropical low.
