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 ]

Preparations

Philippines

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]

Taiwan

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]

Retirement

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.

Nesat was also the first of twin tropical cyclones to batter the Philippines within one week during September 2011, the second was Nalgae.

The 2012 Luzon southwest monsoon floods, was an eight-day period of torrential rain and thunderstorms in Luzon in the Philippines from August 1 to August 8, 2012. Its effects centered on Metro Manila, the surrounding provinces of the Calabarzon region and the provinces of Central Luzon. Not a typhoon in its own right, the storm was a strong movement of the southwest monsoon caused by the pull of Typhoon Saola (Gener) from August 1–3, strengthened by Typhoon Haikui. It caused typhoon-like damage: the most damage caused by rain since September 2009, when Typhoon Ketsana (Ondoy) struck Metro Manila. The heavy rain caused the Marikina River to overflow, destroying areas also affected by Ketsana, triggering a landslide in the Commonwealth area and collapsing the northbound Marcos Highway.

<span class="mw-page-title-main">2020 Pacific typhoon season</span> Typhoon season in the Western Pacific Ocean

The 2020 Pacific typhoon season was 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 fifth-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. 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">Typhoon Koppu</span> Pacific typhoon in 2015

Typhoon Koppu, known in the Philippines as 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> Typhoon season in the Western Pacific Ocean

The 2022 Pacific typhoon season was the third consecutive season to have below-average tropical cyclone activity, with twenty-five named storms, although it was more active than the previous seasons by named storm count. Ten became typhoons, and three of those intensified into super typhoons. 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.

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.

<span class="mw-page-title-main">Typhoon Hagupit (2020)</span> Pacific typhoon in 2020

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.

<span class="mw-page-title-main">Tropical Storm Pakhar (2012)</span> Pacific tropical storm in 2012

Tropical Storm Pakhar was a strong tropical storm that affected the Philippines and the Indochina as a whole in early-April 2012. The fourth tropical depression and the first named storm of the annual typhoon season, Pakhar's origins can be traced from a disturbance that persisted to the northwest of Palau. Located in an overall unfavorable environment, the disturbance crossed the Philippine archipelago before subsequently developed into a tropical depression on March 26. Now under favorable conditions, the depression intensified to a tropical storm, receiving the name Pakhar from the JMA. On the other hand, the JTWC upgraded it to a Category 1 typhoon due to an eye feature; however, this was short-lived as the agency downgraded back Pakhar to a tropical storm due to the system entering colder sea surface temperatures. On April 2, the system made landfall near Vũng Tàu, Vietnam and it dissipated thereafter. Its remnants also affected Cambodia, Laos and Thailand.

<span class="mw-page-title-main">Tropical Storm Kompasu (2021)</span> Pacific tropical storm in 2021

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.

<span class="mw-page-title-main">Tropical Storm Nalgae</span> Pacific severe tropical storm in 2022

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. The 22nd named tropical 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. The next day, the PAGASA and the JTWC upgraded Nalgae to a severe tropical storm status on October 28. Nalgae would eventually made its first landfall in Virac, Catanduanes, which was quickly followed by another landfall thirty minutes later. It then traversed the Bicol Region and emerged into Ragay Gulf, eventually making another landfall. Defying initial forecasts, Nalgae then moved southwestward and struck Mogpog. Afterwards, the storm moved northwestward into the Sibuyan Sea and struck Sariaya. Then it would move through many regions throughout the evening of October 29. Nalgae emerged over the West Philippine Sea the next day and weakened below tropical storm status. The storm would later re-intensify into a severe tropical storm a few hours later, and eventually exited the Philippine Area of Responsibility a day later. Upon its exit from Philippine jurisdiction, Nalgae then intensified into a Category 1-equivalent typhoon on JTWC; however, the JMA maintained its severe tropical storm classification for the system. It then approached the Pearl River Delta. At around 04:50 CST on November 3, 2022, Nalgae made its final landfall at Xiangzhou District as a tropical depression.
