Tropical Storm Aere,known in the Philippines as Tropical Storm Bebeng,was a mild tropical storm that affected eastern Philippines and southern Japan. It was the first named storm of the 2011 Pacific typhoon season. Aere is the Marshallese word for storm . [1]
In the Philippines,Aere brought very heavy rainfall triggering landslides and floods knocking out power in several areas across Luzon. More than 50 flights were canceled or diverted because of the bad weather conditions and President Benigno Aquino III delayed his flight home from a summit in Indonesia by a day. The coastguards have stopped smaller boats from leaving ports in Catanduanes and surrounding areas,leaving 1,379 people stranded. More than 7,200 hectares (17,800 acres - 27 square miles) of rice,corn and high-value crops costing more than 118 million pesos ($2.7 million) were destroyed or damaged. At least 35 people have been killed and two more are missing as a result of Aere. Agricultural losses are estimated at PHP1.37 billion (US$31.7 million).
On 3 May, the JTWC started to monitor a tropical disturbance that had developed within a monsoon trough about 140 km (85 mi) to the west of Palau. [2] At this time the disturbances low level circulation centre was weak and unorganized, while a minimal amount of deep convection was observed around the system. [2] Over the next couple of days the depression gradually developed further before it was declared a tropical depression by the JMA and the JTWC during 6 May. [3] In the same evening, PAGASA upgraded the low pressure into a tropical depression and assigned its local name 'Bebeng'. In the afternoon of 7 May, JMA upgraded the tropical depression to a tropical storm, and assigned the name 'Aere'. During the early morning of 12 May, the JMA downgraded Aere to a tropical depression while south of Kyushu Island.[ citation needed ]
Almost immediately after the PAGASA started monitoring the system, the NDRRMC raised storm warning signal 1 over the areas of Luzon and Visayas. The Philippine National Police were directed to continuously report the events to the NDRRMC as it happened. The Department of Health also alerted all the hospitals in the storm prone regions and asked them to sat in continuous coordination with PAGASA. [4] Soon, the PDRRMC initiated evacuations across the Albay province with a population of 63,964 residing in 152 Barangays already evacuated as a pre-emptive measure. Also, the Armed Forces of the Philippines (AFP) deployed several assault vehicles and military personnel to closely monitor the situation across the nation and to haul rice for relief operations. [5]
Officials in Taiwan issued a sea warning and informed residents on the eastern and southern parts of the island-nation about the torrential rain that Aere may bring. [6] The Central Weather Bureau in Taiwan warned all ships in the Bashi Channel off the southern coast to brace for the storm reporting that the heavy rain may hit eastern and southern Taiwan triggering landslides and flooding. [7]
Early on 8 May, Aere made landfall over Northern Catanduanes bringing very heavy rainfall across the nation. Around 210 passengers in the port of Lucena bound for Marinduque and 125 passengers in the port of Romblon bound for San Fernando, Romblon were stranded after their ships were cancelled due to heavy rains and rough sea conditions caused by the storm. [8] More than 100,000 villagers fled from towns threatened by landslides. Aere triggered landslides and floods knocking out power in several areas across Luzon. [9] Thousands were helped to flee from their farms around Mayon volcano in Albay province, which was threatened by landslides and heavy rains that have resulted in extensive flooding after the storm. A resident in Sorsogon province who was one of the victims expressed views on the storm, saying "The floods were so deep, they went past the head". [10] More than 50 flights were canceled or diverted because of the bad weather conditions caused by Aere. President Benigno Aquino III delayed his flight home from a summit in Indonesia by a day due to the bad weather. [11] The Disaster officials advised several villagers in the archipelago's agricultural regions situated in the north to stay prepared for landslides and flash floods after heavy rains poured by the storm. [12] The coastguards have stopped smaller boats from leaving ports in Catanduanes and surrounding areas, leaving 1,379 people stranded after the NDRRMC's announcement that the security at coasts must be tightened. [13] More than 7,200 hectares (17,800 acres - 27 square miles) of rice, corn and high-value crops costing more than 118 million pesos ($2.7 million) were destroyed or damaged. [14] According to the National Disaster Risk Reduction and Management Council, at least 35 people have been killed and two more are missing as a result of Aere. Agricultural losses are estimated at PHP1.37 billion (US$31.7 million). [15] Widespread flooding and landslides damaged homes, blocked off roads and severed communications. In Catarman, Northern Samar, 377.4 mm (14.86 in) of rain fell in just 24 hours, resulted in significant flash flooding. [16]
Following the storm's severe damages and impacts in the Philippines, in June 2012, the PAGASA announced that the name Bebeng would be retired and will be replaced by Betty, which was first used in the 2015 season.
Typhoon Babs, known in the Philippines as Typhoon Loleng, was a powerful typhoon that struck the Philippines days after Typhoon Zeb hit the same area. The seventh typhoon of the inactive 1998 Pacific typhoon season, Babs formed on October 14 between the Philippines and Guam. The storm moved westward initially, failing to intensify initially due to the outflow from Typhoon Zeb to the northwest. Babs slowed and briefly turned to the south before advancing to the northwest, whereupon it rapidly intensified into a strong typhoon. On October 20, the official Japan Meteorological Agency (JMA) estimated peak 10‑minute winds of 155 km/h (96 mph), while the unofficial Joint Typhoon Warning Center (JTWC) estimated peak 1‑minute winds of 250 km/h (160 mph), making Babs an unofficial super typhoon. The storm struck the Philippine island of Catanduanes at that intensity and weakened slightly before hitting Luzon. Babs turned northward once in the South China Sea, later weakening due to unfavorable conditions and transitioning into an extratropical cyclone on October 27 in the Taiwan Strait.
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.
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.
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.
The 2016 Pacific typhoon season is considered to have been the fourth-latest start for a Pacific typhoon season since reliable records began. It was an average season, with a total of 26 named storms, 13 typhoons, and six super typhoons. The season ran throughout 2016, though typically most tropical cyclones develop between May and October. The season's first named storm, Nepartak, developed on July 3, while the season's last named storm, Nock-ten, dissipated on December 28.
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.
Severe Tropical Storm Nock-ten, known in the Philippines as Severe Tropical Storm Juaning, was a strong tropical storm which made a total of four landfalls in Southeast Asia, killing more than 100 people and causing damage estimated at US$126 million. It was the eighth named storm and the fourth severe tropical storm of the 2011 Pacific typhoon season.
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.
Typhoon Nesat, known in the Philippines as Typhoon Pedring, was the most powerful tropical cyclone to directly impact China since 2008. It also struck the Philippines during late September 2011, killing 98 people. It is the 17th named storm, the 11th severe tropical storm, the 7th typhoon and overall, the 30th tropical cyclone to be monitored by the Japan Meteorological Agency(JMA) during the year. Nesat came exactly two years after Typhoon Ketsana made landfall in the Philippines as the most devastating typhoon in the 2009 Pacific typhoon season with a damage of US$1.09 billion and 747 fatalities. Nesat was also the first of twin tropical cyclones to batter the Philippines within one week during September 2011, the second was Nalgae.
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.
Severe Tropical Storm Trami, known in the Philippines as Severe Tropical Storm Maring, was a tropical cyclone that brought heavy rains to Taiwan and East China during mid-August 2013. Trami also made a fujiwhara interaction with Tropical Depression 13W north of it. The storm also enhanced the southwest monsoon causing more than 20 casualties in the Philippines.
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.
Typhoon Rammasun, known in the Philippines as Typhoon Glenda, was one of the only four Category 5 super typhoons on record in the South China Sea, with the other ones being Pamela in 1954, Rai in 2021 and Yagi in 2024. Rammasun had destructive impacts across the Philippines, South China, and Vietnam in July 2014. Rammasun is a Thai word for thunder god. After Lingling and Kajiki earlier in 2014, Rammasun became the third tropical cyclone, and first typhoon to directly impact the Philippines in 2014. The ninth named storm and the third typhoon of the annual typhoon season, Rammasun formed in the Intertropical Convergence Zone, an area near the equator where the northeast and southeast trade winds come together, and slowly drifted northwest. Having passed through the islands of Micronesia, the system turned west and quickly moved under the influence of a subtropical ridge (STR). Rammasun posed a significant threat to the Philippine island of Luzon, as it was expected to reach typhoon intensity before making landfall there. Though initially forecast to make landfall in Cagayan Valley, the storm followed a more westerly path and was later forecast to make landfall in Rapu-Rapu, Albay in Bicol Region and then pass through Bataan and Zambales before brushing past Metro Manila.
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.
Tropical Storm Bolaven, known in the Philippines as Tropical Storm Agaton, was an early-season tropical cyclone that affected southern parts of the Philippines in January 2018. The first named storm of the 2018 Pacific typhoon season, Bolaven formed as a tropical depression near Palau on December 29, 2017. The system moved generally westwards without intensifying and made landfall over northeastern Mindanao on January 1, 2018. The depression spent the next day traversing the Philippines, making four more landfalls in the Visayas and one in Palawan. The system strengthened into a tropical storm on January 3 as it entered the South China Sea, receiving the name Bolaven. However, Bolaven weakened back to a tropical depression just a day later amid a marginal environment and dissipated on January 4 east of Vietnam.
Tropical Depression Josie was a weak tropical system that impacted the Philippine archipelago of Luzon in July 2018, bringing widespread flooding. The tropical depression was classified in the South China Sea on July 20, and steadily moved eastward while gradually intensifying. The storm reached its peak intensity of 1-minute sustained winds of 65 km/h while nearing the northern tip of the Ilocos Region. By July 22, the system moved northward and rapidly weakened. The system was last noted on July 23 to the northeast of Taiwan.
Typhoon Hagupit, known in the Philippines as Severe Tropical Storm Dindo, was a Category 1 typhoon that heavily impacted Eastern China and South Korea in August 2020. It was the fourth named storm and the second typhoon of the annual typhoon season. The JMA began monitoring a tropical depression that developed in the Philippine Sea on July 30, with PAGASA assigning the name “Dindo” to the storm, later that day it strengthened into a tropical storm, according to the JMA. PAGASA issued its final advisory on Dindo early on August 3, as it moved out of their area of responsibility. Hagupit intensified into a typhoon on August 3, before making landfall in Wenzhou, China at 19:30 UTC that day at peak intensity. Hagupit subsequently weakened over China, before degenerating into an extratropical low on August 5. Hagupit's remnants persisted for another several days, as the storm moved eastward, before dissipating south of Alaska on August 14.
Severe Tropical Storm Kompasu, known in the Philippines as Severe Tropical Storm Maring was a very large and deadly tropical cyclone that affected the Philippines, Taiwan, and southeast China. Part of the 2021 Pacific typhoon season, Kompasu originated from an area of low pressure east of the Philippines on 6 October 2021. The Japan Meteorological Agency (JMA) classified it as a tropical depression that day. A day later, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) classified it as a tropical depression, naming it Maring. The cyclone was initially heavily disorganised, competing with another vortex, Tropical Depression Nando. Eventually, Maring became dominant, and the JMA reclassified it as a tropical storm, naming it Kompasu. Kompasu made landfall in Cagayan, Philippines, on 11 October 2021, and two days later, the storm made landfall in Hainan, China. The cyclone dissipated on 14 October 2021 while located over Vietnam.
Severe Tropical Storm Nalgae, known in the Philippines as Severe Tropical Storm Paeng, was a very large and deadly tropical cyclone that wreaked havoc across the Philippines and later impacted Hong Kong and Macau. Nalgae, meaning wing in Korean, the twenty-second named storm of the 2022 Pacific typhoon season, Nalgae originated from an invest located east of the Philippines on October 26. The disturbance, initially designated as 93W, was eventually upgraded the following day to a tropical depression by the Joint Typhoon Warning Center (JTWC) and re-designated as 26W. The Japan Meteorological Agency (JMA) however, had already considered the disturbance as a tropical depression a day prior to JTWC's; the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) also followed the JMA's lead and gave it the name Paeng. That same day, it was upgraded again by the JMA to tropical storm status, thus gaining the name Nalgae.
