In December 2022, a series of floods began to severely affect the provinces of Misamis Occidental and Misamis Oriental, and some parts of the southern island of Mindanao in the Philippines. The floods were caused by intense rain, which poured down on the central and southern parts of the country. [4] [5] [6] [7]

Contents

Cause

The Philippine Atmospheric Geophysical and Astronomical Services Administration (PAGASA) said in a statement that the widespread rains were triggered by the shear line collision located within the regions of Visayas and Mindanao. The shear line then persisted towards the Eastern Visayas and CARAGA regions in the central and northern parts of the country. [8] [9] Low pressure areas and northeast monsoon also contributed. [10]

Impact

The provincial government of Misamis Occidental declared a state of calamity (SOC) as they received the full brunt of the flooding. The cities of Gingoog, Ozamiz, and provincial capital of Oroquieta, as well as surrounding municipalities were most affected by the floods. [11] Samar, Northern Samar and Eastern Samar also declared SOC. [12] [13] [14]

It was first classified as a weak tropical depression on December 16. The system gradually intensified and consolidated into a tropical storm on December 20. Tembin made landfall in Mindanao late the next day. On December 23, Tembin followed a path towards the South China Sea and intensified into a typhoon early the following day. Quick intensification ensued and Tembin reached its peak intensity as a low-end Category 2 typhoon as assessed by the Joint Typhoon Warning Center on December 24. Unfavorable conditions enhanced by the winter monsoon caused Tembin to rapidly weaken shortly afterwards, before it ultimately dissipated on December 26 while just south of Vietnam.

Tropical Storm Kai-tak, known in the Philippines as Tropical Storm Urduja, was a late-season tropical cyclone that affected Visayas during December 2017. Forming as the twenty-sixth named storm of the 2017 Pacific typhoon season, Kai-tak formed as a tropical depression near Palau on December 11. Slowly intensifying, the system became a tropical storm on December 14. Due to its slow motion, Kai-tak made landfall in Samar on December 16, and traversed the Philippine islands. Kai-tak later moved in a west-southwestward direction until it dissipated on December 23 near Malaysia.

However, due to unfavorable conditions, the depression weakened into a remnant low on December 29, while making landfall over Eastern Samar thereafter.

<span class="mw-page-title-main">Typhoon Kammuri</span> Pacific typhoon in 2019

Typhoon Kammuri, known in the Philippines as Typhoon Tisoy, was a powerful typhoon which impacted the Philippines in early December 2019. Kammuri, which means crown or Corona Borealis in Japanese, the twenty-eighth named storm and sixteenth typhoon of the 2019 Pacific typhoon season, Kammuri developed from a tropical wave situated a couple hundred kilometers south of the Mariana Islands. From November 25 to 27, the system tracked westward at a steady pace and rate of intensification, first making minor impacts in Guam. On November 28, the system intensified into a typhoon as environmental conditions became marginally conducive for significant development. From November 29 to December 1, Kammuri was unable to strengthen to previous estimates due to its near stationary movement as a result of weak steering currents, upwelling itself consequently. On December 2, the system tracked westward at a much faster speed of 19 km/h (12 mph) and rapidly intensified over warm Philippine Sea waters, before making landfall in the Bicol Region of the Philippines at peak intensity as a category 4-equivalent typhoon.

Typhoon Vongfong, known in the Philippines as Typhoon Ambo, was a strong tropical cyclone that impacted the Philippines in May 2020. Beginning as a tropical depression on May 10 east of Mindanao, Vongfong was the first storm of the 2020 Pacific typhoon season. It gradually organized as it took a slow northward course, strengthening into a tropical storm on May 12 and curving west thereafter. The next day, Vongfong entered a period of rapid intensification, becoming a typhoon and attaining 10-minute maximum sustained winds of 150 km/h (93 mph). The storm made landfall at this intensity near San Policarpo, Eastern Samar, at 04:15 UTC on May 14. The system tracked across Visayas and Luzon, making a total of seven landfalls. Persistent land interaction weakened Vongfong, leading to its degeneration into a tropical depression over the Luzon Strait on May 17.

Typhoon Vamco, known in the Philippines as Typhoon Ulysses, was a powerful and very destructive Category 4-equivalent typhoon that struck the Philippines and Vietnam. It also caused the worst flooding in Metro Manila since Typhoon Ketsana in 2009.

Tropical Storm Dujuan, known in the Philippines as Severe Tropical Storm Auring, was a tropical storm which caused heavy rain in the Philippines and Palau, leading to minor damage. Dujuan was the second depression and first named storm of the 2021 Pacific typhoon season. Dujuan started as a tropical depression in the Philippine Sea which slowly tracked northwestward towards the Philippines. Its strength fluctuated from February 19 to 21 due to an unfavorable environment near the storm at the time. The system was declared a tropical storm prior to its landfall in Batag Island, Laoang, Northern Samar on February 22.

The third named storm of the 2021 Pacific typhoon season, Choi-wan originated from an area of low pressure, located south-southeast of Guam near a brewing system. Fueled by an environment favorable for tropical cyclogenesis, it developed into a tropical depression, two days later as it moved westward. At 00:00 UTC on May 31, the system strengthened to a tropical storm and was named Choi-wan by the JMA. Although the storm was still located in the conductive conditions off the Philippine Sea while moving northwestward, a tropical upper tropospheric trough to the northeast halted the system's intensification, with Choi-wan's convection displaced to the south of its circulation on satellite imagery.

<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. 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. 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.
