The Philippines is a Typhoon (Tropical Cyclone)-prone country, with approximately 20 Tropical Cyclones entering its area of responsibility per year. Locally known generally as bagyo ( [bɐgˈjoʔ] ), [3] typhoons regularly form in the Philippine Sea and less regularly, in the South China Sea, with the months of June to September being the most active, August being the month with the most activity. Each year, at least ten typhoons are expected to hit the island nation, with five expected to be destructive and powerful. [4] In 2013, Time declared the country as the "most exposed country in the world to tropical storms". [5]

Typhoons typically make an east-to-west route in the country, heading north or west due to the Coriolis effect. As a result, landfalls occur in the regions of the country that face the Pacific Ocean, especially Eastern Visayas, Bicol Region, and northern Luzon, [5] whereas Mindanao is largely free of typhoons. Climate change is likely to worsen the situation, with extreme weather events including typhoons posing various risks and threats to the Philippines. [6]

Typhoon Yolanda, internationally known as Haiyan, is the deadliest typhoon to have affected the country in recorded history, killing more than 6,300 people as it crossed the Visayas region in November 2013. The strongest typhoon to make landfall in the country, as well as the strongest tropical cyclone landfall worldwide was Typhoon Rolly, internationally known as Goni, which struck Catanduanes in November 2020 with 1-minute sustained winds of 315 km/h (195 mph). The wettest known tropical cyclone to impact the archipelago was the July 14–18, 1911 cyclone which dropped over 2,210 millimetres (87 in) of rainfall within a 3-day, 15-hour period in the northern city of Baguio. [7] Tropical cyclones usually account for at least 30 percent of the annual rainfall in the northern Philippines while being responsible for less than 10 percent of the annual rainfall in the southern islands. According to the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) in 2016, the number of destructive typhoons the country experienced annually have increased, but notes that it is too early to call it a trend. [4]

PAGASA is the state weather agency of the Philippines. Yearly, the agency gives a local name to the typhoons that enter its area of responsibility in addition to the international name given by the Japan Meteorological Agency (JMA), the designated Regional Specialized Meteorological Center (RSMC) by the World Meteorological Organization (WMO). The state agency also regularly issues weather bulletins and advisories to the public especially during typhoons. It uses a five-point warning scale that are issued to the entirety or parts of the provinces and localities affected by a typhoon. [8] [9]

The National Disaster Risk Reduction and Management Council (NDRRMC) is the country's top agency for preparation and response to calamities and natural disasters, including typhoons. Additionally, each province and local government units has their own Disaster Risk Reduction and Management Office (DRRMO). Each provincial and local government is required to set aside 5% of its annual budget for disaster risk reduction, preparations, and response. [4]

The frequency of typhoons in the Philippines have made typhoons a significant part of everyday ancient and modern Filipino culture. [5]

Etymology

Bagyo (sometimes spelled bagyu or bagyio [3] ) is the word for 'typhoon' or 'storm' in most Philippine languages, including Tagalog, Visayan, Ilocano, Bicolano, Hanunó'o, Aklanon, Pangasinan and Kapampangan. It is derived from Proto-Austronesian *baRiuS, meaning 'typhoon'. Cognates in other Austronesian languages include Sama baliw ('wind'), Amis faliyos or farios ('typhoon'); Saisiyat balosh ('typhoon'), Babuza bayus ('storm'), Puyuma variw, Bintulu bauy ('wind'), Kelabit bariw ('storm wind'), and Chamorro pakyo ('typhoon'). [10]

The Joint Typhoon Warning Center in Honolulu started monitoring and naming storms in the Western Pacific region in 1945, originally using female names in English alphabetical order. That list was revised in 1979 by introducing male names to be used in alternation with the female names. [11] The Philippine Weather Bureau started naming storms within their area of responsibility in 1963, using female Filipino names in the former native alphabetical order. The Bureau continued to monitor typhoons until the agency's abolition in 1972, after which its duties were transferred to the newly established PAGASA. This often resulted in a Western Pacific cyclone carrying two names: an international name and a local name used within the Philippines. This two-name scheme is still followed as of 2024.

In 2000, cyclone monitoring duties in the Western Pacific were transferred from the JTWC to the Japan Meteorological Agency, the RSMC of the World Meteorological Organization. The international naming scheme of the typhoons was replaced with a sequential list of names contributed by 14 nations in the region, including the Philippines. The new scheme largely uses terms for local features of the contributing nation, such as animals, plants, foods and adjectives in the native language. The rotation of names is based on the alphabetical order of the contributing nations. The Philippines, however, would maintain its own naming scheme for its local forecasts. In 2001, PAGASA revised its naming scheme to contain longer annual lists with a more mixed set of names.

Currently, the JMA and PAGASA each assign names to typhoons that form within or enter the Philippine Area of Responsibility. The JMA naming scheme for international use contains 140 names described above. The list is not restricted by year; the first name to be used in a typhoon season is the name after the last-named cyclone of the preceding season. [12] The PAGASA naming scheme for Philippine use contains four lists, each containing twenty-five names arranged in alphabetical order. Every typhoon season begins with the first name in the assigned list, and the rolls of names are each reused every four years. An auxiliary list of ten names is used when the main list in a year had been exhausted. [13] Not all Western Pacific cyclones are given names by both weather agencies, as JMA does not name tropical depressions, and PAGASA does not name cyclones outside the Philippine Area of Responsibility.

In the case of both weather agencies, names are retired after a typhoon that carried it caused severe or costly damage and loss of life. Retirement is decided by the agencies' committees, although in PAGASA's case, names are routinely retired when the cyclone caused at least 300 deaths or ₱1 billion in damage in the Philippines. Retired names are replaced with another name for the next rotation, for JMA by the nation that submitted the retired name, and for PAGASA with a name sharing the same first letter as the retired name.

On an annual time scale, activity reaches a minimum in May, before increasing steadily to June, and spiking from July to September, with August being the most active month for tropical cyclones in the Philippines. Activity reduces significantly in October. [14] The most active season, since 1945, for tropical cyclone strikes on the island archipelago was 1993 when nineteen tropical cyclones moved through the country (though there were 36 storms that were named by PAGASA). [15] There was only one tropical cyclone which moved through the Philippines in 1958. [16] The most frequently impacted areas of the Philippines by tropical cyclones are northern Luzon and eastern Visayas. [17] A ten-year average of satellite determined precipitation showed that at least 30 percent of the annual rainfall in the northern Philippines could be traced to tropical cyclones, while the southern islands receive less than 10 percent of their annual rainfall from tropical cyclones. [18]

PAGASA releases typhoon warnings to the public. Until recently, the warning scale it used was a four-point scale, with Signal #4 being the highest possible warning issued to a locality. However, a fifth warning signal was introduced in the 2010s for powerful typhoons since Typhoon Yolanda (Haiyan) in 2013. In 2022, PAGASA revised its own definition for a "super typhoon" and its warning signals. [20] [9] An area having a storm signal may be under:

These warning signals are usually raised when a locality is about to be hit by a typhoon. As it gains strength and/or gets nearer to an area having a storm signal, the warning may be upgraded to a higher one for that particular area. Conversely, as a tropical cyclone weakens and/or gets farther to an area, it may be downgraded to a lower signal or may be lifted altogether.

Classes in the localities that are under by a warning signal are cancelled or suspended depending on how high the signal is: preschool for Signal #1, elementary and below for Signal #2, high school (including senior high school) and below for Signal #3, and all educational levels (including colleges and universities) for Signal #4 and above. These applies for both public and private schools in the affected locality, although local governments can declare suspensions and cancellations of classes at their own discretion regardless of the warning signal.

List of Philippine typhoons

Pre–1963

The JTWC was already naming tropical cyclones in the Northwest Pacific basin since 1945, before the Philippines did so. Only a few notable storms persisted before 1963. A tropical cyclone assumably impacted Northern Luzon in July 1911, in which a record-breaking precipitation level was seen in Baguio, with 2,210 mm (87 in) of rainfall being dumped by the storm. In November 1912, a typhoon swept through the central Philippines and "practically destroyed" Tacloban. In Tacloban and Capiz on the island of Panay, the death toll was 15,000, half the population of those cities at the time. [21]

1963–1999

In 1963, the PAGASA began naming tropical cyclones that enter their area of responsibility using female names ending with "ng". During the period 1963 to 1999, the Philippines experienced several typhoons that affected or made landfall. Moreover, this period saw the most active typhoon season in the Philippines ― with 31 typhoons being named by PAGASA ― in 1993.

This period saw several notable and deadly typhoons that passed anywhere in the country. Typhoon Patsy (Yoling) of 1970 became one of the deadliest typhoons to strike Metro Manila. [22] Typhoon Nina (Sisang) in 1987 became one of the strongest typhoons to hit the Bicol Region. Typhoon Yunya (Diding) in June 1991 struck Luzon at the time of the colossal eruption of Mount Pinatubo. Later in the same year, Tropical Storm Thelma (Uring) became one of the most deadliest storms to hit the country, killing just over 5,000 people.

2000–present

In the beginning of this period, significant changes were seen in the naming of tropical cyclones in the Northwest Pacific ― the Japan Meteorological Agency (JMA), as the Regional Specialized Meteorological Center (RSMC) of the basin, took over the naming of tropical cyclones by 2000, [12] and the PAGASA revised its naming scheme to contain longer annual lists with a more mixed set of names by 2001. Adjustments in the Philippine cyclone names also occurred in 2005 and in 2021.

The strongest typhoon to make landfall in the country during this time period was Typhoon Goni (Rolly) in early November 2020, with 1-minute sustained winds of 315 km/h (195 mph). Typhoon Haiyan (Yolanda) is the most deadly Philippine typhoon during this period, killing more than 6,300 people. Other notable Philippine storms during this period include Typhoon Ketsana (Ondoy) in September 2009 which became the most devastating tropical cyclone to hit Manila, [23] and Typhoon Bopha (Pablo) in December 2012, which became the strongest typhoon on record to hit Mindanao.

The Philippines is reeling from Typhoon Man-yi, which displaced hundreds of thousands, caused widespread destruction, and worsened the impact of recent storms, leaving millions in urgent need of aid and recovery support. [24]

<span class="mw-page-title-main">2003 Pacific typhoon season</span>

The 2003 Pacific typhoon season was a slightly below average yearlong period of tropical cyclogenesis exhibiting the development of 45 tropical depressions, of which 21 became named storms; of those, 14 became typhoons. Though every month with the exception of February and March featured tropical activity, most storms developed from May through October. During the season, tropical cyclones affected the Philippines, Japan, China, the Korean Peninsula, Indochina, and various islands in the western Pacific.

<span class="mw-page-title-main">1980 Pacific typhoon season</span>

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.

<span class="mw-page-title-main">Typhoon Soudelor (2003)</span> Pacific typhoon in 2003

Typhoon Soudelor, known in the Philippines as Typhoon Egay, was a powerful typhoon that underwent rapid deepening east of Taiwan in the 2003 Pacific typhoon season. It was the sixth named storm by the Japan Meteorological Agency (JMA) of the season, as well as the third typhoon. It formed on June 12 from a disturbance in the monsoon trough, located east of the Philippines. The system moved generally to the northwest after its genesis, gradually intensifying into a tropical storm. While offshore the Philippines, Soudelor dropped heavy rainfall that caused flooding and left thousands homeless. The storm caused $2.46 million in damage, and 12 deaths.

<span class="mw-page-title-main">Tropical Storm Maysak (2008)</span> Pacific severe tropical storm in 2008

Severe Tropical Storm Maysak, known in the Philippines as Tropical Storm Quinta-Siony, was recognised as the 19th tropical storm by the Japan Meteorological Agency. It was also recognised as the 24th tropical depression and the 22nd tropical storm by the Joint Typhoon Warning Center of the 2008 Pacific typhoon season.

<span class="mw-page-title-main">2011 Pacific typhoon season</span>

The 2011 Pacific typhoon season was a below average season that produced a total of 21 named storms, 8 typhoons, and four super typhoons. This season was much more active than the previous season, although both seasons were below the Pacific typhoon average of 26. The season ran throughout 2011, though most tropical cyclone tend to develop between May and October. The season's first named storm, Aere, developed on May 7 while the season's last named storm, Washi dissipated on December 19.

<span class="mw-page-title-main">2013 Pacific typhoon season</span>

The 2013 Pacific typhoon season was a devastating and catastrophic season that was the most active since 2004, and the deadliest since 1975. It featured Typhoon Haiyan, one of the most powerful storms in history, as well as one of the strongest to make landfall on record. It featured 31 named storms, 13 typhoons, and five super typhoons. The season's first named storm, Sonamu, developed on January 4 while the season's last named storm, Podul, dissipated on November 15. Collectively, the storms caused 6,829 fatalities, while total damage amounted to at least $26.41 billion (USD), making it, at the time, the costliest Pacific typhoon season on record, until it was surpassed five years later. As of 2024, it is currently ranked as the fifth-costliest typhoon season.

<span class="mw-page-title-main">2014 Pacific typhoon season</span>

The 2014 Pacific typhoon season was a slightly below average season in terms of named storms, but featured the highest amount of Category 5 typhoons since 1997. This was mainly due to a developing El Niño that favors multiple powerful storms to form in the basin. The season formed twenty-three tropical storms, eleven typhoons, eight super typhoons, and seven Category 5 typhoons. The season's peak months August and September saw minimal activity caused by an unusually strong and a persistent suppressing phase of the Madden–Julian oscillation (MJO). The season ran throughout 2014, though most tropical cyclones typically develop between May and October. The season began with the development of Tropical Storm Lingling on January 18, and ended after Tropical Storm Jangmi which dissipated on January 1 of the next year.

<span class="mw-page-title-main">2017 Pacific typhoon season</span>

The 2017 Pacific typhoon season was a below-average season in terms of accumulated cyclone energy and the number of typhoons and super typhoons, and the first since the 1977 season to not produce a Category 5-equivalent typhoon on the Saffir–Simpson scale. The season produced a total of 27 named storms, 11 typhoons, and only two super typhoons, making it an average season in terms of storm numbers. It was an event in the annual cycle of tropical cyclone formation, in which tropical cyclones form in the western Pacific Ocean. The season runs throughout 2017, though most tropical cyclones typically develop between May and October. The season's first named storm, Muifa, developed on April 25, while the season's last named storm, Tembin, dissipated on December 26. This season also featured the latest occurrence of the first typhoon of the year since 1998, with Noru reaching this intensity on July 23.

<span class="mw-page-title-main">Typhoon Nanmadol (2011)</span> Pacific typhoon in 2011

Typhoon Nanmadol, known in the Philippines as Super Typhoon Mina, was the strongest tropical cyclone in 2011 to hit the Philippines and also the second most intense tropical cyclone worldwide in 2011, and the first of the year to directly impact Taiwan and the rest of the Republic of China (ROC). Becoming the eleventh named storm, the seventh severe tropical storm and the fourth typhoon of the 2011 Pacific typhoon season, Nanmadol made a total of three landfalls killing 26, and causing widespread damage worth US$26,464,591. The area of low pressure that was about to become Nanmadol formed on August 19. It drifted north and became a tropical depression on August 21, a tropical storm on August 23 and a typhoon on the same night. Nanmadol reached peak strength with winds of 100 knots and 140 knots threatening the Philippines with heavy rain and flash flooding.

<span class="mw-page-title-main">2020 Pacific typhoon season</span>

The 2020 Pacific typhoon season was the first of a series of four below average Pacific typhoon seasons, and became the first with below-average tropical cyclone activity since 2014, with 23 named storms, 10 of which became typhoons and only 2 became super typhoons. This low activity was a consequence of La Niña that persisted from the summer of the year. It had the sixth-latest start in the basin on record, slightly behind 1973, and was the first to start that late since 2016. The first half of the season was unusually inactive, with only four systems, two named storms and one typhoon at the end of July. Additionally, the JTWC recorded no tropical cyclone development in the month of July, the first such occurrence since reliable records began. Despite that, this season featured Super Typhoon Goni, which made the strongest landfall worldwide in terms of 1-minute wind speed. The season's first named tropical cyclone, Vongfong, developed on May 8, while the season's last named tropical cyclone, Krovanh, dissipated on December 24. However, the season's last system was an unnamed tropical depression which dissipated on December 29.

<span class="mw-page-title-main">Tropical Storm Rumbia (2013)</span> Pacific severe tropical storm in 2013

Severe Tropical Storm Rumbia, known in the Philippines as Tropical Storm Gorio, was a tropical cyclone that brought widespread flooding in areas of the Philippines and China late June and early July 2013. The sixth internationally named storm of the season, Rumbia formed from a broad area of low pressure situated in the southern Philippine Sea on June 27. Steadily organizing, the initial tropical depression moved towards the northwest as the result of a nearby subtropical ridge. On June 28, the disturbance strengthened to tropical storm strength, and subsequently made its first landfall on Eastern Samar in the Philippines early the following day. Rumbia spent roughly a day moving across the archipelago before emerging into the South China Sea. Over open waters, Rumbia resumed strengthening, and reached its peak intensity with winds of 95 km/h (50 mph) on July 1, ranking it as a severe tropical storm. The tropical cyclone weakened slightly before moving ashore the Leizhou Peninsula late that day. Due to land interaction, Rumbia quickly weakened into a low pressure area on July 2 and eventually dissipated soon afterwards.

<span class="mw-page-title-main">Timeline of the 2013 Pacific typhoon season</span>

Most of the tropical cyclones of the 2013 Pacific typhoon season formed between May and November of that year. The scope of this article is the Pacific Ocean north of the equator, between 100°E and the International Date Line. Tropical storms which form in the Western Pacific basin are assigned a name by the Japan Meteorological Agency (JMA). Tropical depressions forming in this basin are given a number with a "W" suffix by the United States' Joint Typhoon Warning Center (JTWC). The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) assigns names to tropical cyclones that enter or form in the Philippine area of responsibility, but these names are not in common use outside the Philippines.

<span class="mw-page-title-main">Typhoon Krosa (2013)</span> Pacific typhoon in 2013

Typhoon Krosa, known in the Philippines as Typhoon Vinta, was a typhoon that made landfall in the northern Philippines in late October 2013. Forming on October 27 near Guam, the storm slowly intensified while moving westward. Krosa developed an eye and became a typhoon before striking Luzon on October 31. The storm weakened over land, but re-intensified over the South China Sea, reaching peak winds of 150 km/h (93 mph) on November 2 off the southeast coast of China. Typhoon Krosa stalled and encountered unfavorable conditions, resulting in quick weakening. By November 3, it had weakened to tropical storm status, and was no longer being warned on by the next day. In northern Luzon, Krosa damaged 32,000 houses, including 3,000 that were destroyed, and caused four fatalities. High winds and rainfall left ₱277 million in damage.

<span class="mw-page-title-main">Tropical Storm Podul (2013)</span> Pacific tropical storm in 2013

Tropical Storm Podul, known in the Philippines as Tropical Depression Zoraida, was a weak but destructive tropical cyclone that affected the Philippines shortly after the devastating Typhoon Haiyan. The 31st named storm of the 2013 Pacific typhoon season, Podul developed as a tropical depression on November 11 between Palau and the Philippine island of Mindanao. The system moved west-northwestward and struck Davao Oriental in Mindanao on November 12, bringing heavy rainfall that killed two people and disrupted relief efforts following Haiyan. After crossing the Philippines, the depression intensified into Tropical Storm Podul on November 14. Shortly thereafter, the storm struck southeastern Vietnam, and its circulation dissipated on November 15. In Vietnam, Podul produced heavy rainfall that resulted in severe flooding. The storm damaged or destroyed 427,258 houses, and overall damage was estimated at 4.1 trillion₫. Podul killed 44 people in the country and caused 66 injuries.

<span class="mw-page-title-main">Tropical Storm Lingling (2014)</span> Pacific tropical storm in 2014

Tropical Storm Lingling, known in the Philippines as Tropical Depression Agaton, was a weak but deadly tropical cyclone that affected the Philippines in January 2014. The first named storm of the annual typhoon season, this early-season cyclone remained very disorganized throughout its lifespan. Lingling was the first major natural disaster in the Philippines after Typhoon Haiyan just two months earlier, as it caused widespread landslide incidents and floods in Mindanao, resulting in 70 deaths and damage amounting to over 566 million pesos on the island.

<span class="mw-page-title-main">Typhoon Hagupit (2014)</span> Pacific typhoon in 2014

Typhoon Hagupit known in the Philippines as Super Typhoon Ruby, was the second most intense tropical cyclone in 2014. Hagupit particularly impacted the Philippines in early December while gradually weakening, killing 18 people and causing $114 million of damage in the country. Prior to making landfall, Hagupit was considered the worst threat to the Philippines in 2014, but it was significantly smaller than 2013's Typhoon Haiyan.

<span class="mw-page-title-main">Effects of the 2013 Pacific typhoon season in the Philippines</span>

The effects of the 2013 Pacific typhoon season in the Philippines were considered some of the worst in decades. Throughout the year, a series of typhoons impacted the country, with the worst impacts coming from Typhoon Haiyan, especially in death toll, during November.

<span class="mw-page-title-main">Typhoon Koppu</span> Pacific typhoon in 2015

Typhoon Koppu, known in the Philippines as Super Typhoon Lando, was a powerful and devastating tropical cyclone that struck Luzon in October 2015. It was the twenty-fourth named storm and the fifteenth typhoon of the annual typhoon season. Similar to Goni earlier in the year, Koppu originated from a tropical disturbance east of the Mariana Islands on October 10. Moving briskly west, the system consolidated into a tropical depression the following day and further into a tropical storm on October 13. Situated over the warm waters of the Philippine Sea, Koppu quickly deepened. The storm reached its peak intensity on October 17 with ten-minute sustained winds of 185 km/h (115 mph) according to the Japan Meteorological Agency (JMA). The Joint Typhoon Warning Center assessed Koppu to have been a Category 4-equivalent super typhoon with one-minute sustained winds of 240 km/h (150 mph). The storm subsequently made landfall at this strength near Casiguran, Philippines. Rapid weakening ensued due to interaction with the mountainous terrain of Luzon and the disheveled core of Koppu emerged over the South China Sea on October 19. Unfavorable environmental conditions inhibited reorganization and the system diminished to a tropical depression on October 21.

<span class="mw-page-title-main">2022 Pacific typhoon season</span>

The 2022 Pacific typhoon season was the third consecutive season to have below average tropical cyclone activity, with twenty-five named storms forming. Of the tropical storms, ten became typhoons, and three would intensify into super typhoons. The season saw near-average activity by named storm count, although many of the storms were weak and short-lived, particularly towards the end of the season. This low activity was caused by an unusually strong La Niña that had persisted from 2020. The season's first named storm, Malakas, developed on April 6, while the last named storm, Pakhar, dissipated on December 12. The season's first typhoon, Malakas, reached typhoon status on April 12. The season ran throughout 2022, though most tropical cyclones typically develop between May and October. Tropical storms Megi and Nalgae were responsible for more than half of the casualties, while typhoons Hinnamnor and Nanmadol both caused $1 billion in damages.

<span class="mw-page-title-main">Tropical Cyclone Wind Signals</span> Weather alerts in the Philippines

The Tropical Cyclone Wind Signals are tropical cyclone alert levels issued by the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) to areas within the Philippines that may be affected by tropical cyclone winds and their associated hazards.
