Super Typhoon Man-yi (Pepito) Smashes the Philippines
Introduction
Super Typhoon Man-yi, locally known as Pepito, was a formidable tropical cyclone that struck the Philippines in mid-November 2024. As the twenty-fourth named storm and the sixth super typhoon of the 2024 Pacific typhoon season, Man-yi's impact was particularly devastating, marking the culmination of a series of severe weather events that had battered the nation over a short period.
Meteorological Background
Man-yi originated from an area of convection approximately 120 nautical miles east of Kwajalein Atoll on November 8, 2024. Satellite imagery indicated an increasingly organized low-level circulation center accompanied by persistent deep convection on its southwestern periphery. As the system tracked northwestward, the Japan Meteorological Agency (JMA) upgraded it to a tropical storm, assigning the name Man-yi, as it passed near Guam on November 13. By November 15, the storm had intensified into a typhoon, with the Joint Typhoon Warning Center (JTWC) subsequently classifying it as a super typhoon, noting one-minute sustained winds reaching 140 knots. The JMA reported ten-minute sustained winds of 105 knots and a central pressure of 920 hPa at its peak intensity.
Preparations and Evacuations
In anticipation of Man-yi's landfall, various precautionary measures were implemented across the Philippines. The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) issued Tropical Cyclone Wind Signals for several regions, including Catanduanes, Northern Samar, Camarines Sur, Albay, Sorsogon, Samar, and Eastern Samar. The agency also warned of potential storm surges up to 3 meters affecting areas such as Cagayan Valley, Central Luzon, Calabarzon, Mimaropa, the Bicol Region, and Eastern Visayas. The Philippine Institute of Volcanology and Seismology (PHIVOLCS) cautioned about possible lahar flows from the Taal, Pinatubo, and Mayon volcanoes due to the anticipated heavy rainfall.
Local governments initiated extensive evacuation procedures, with over 1.2 million individuals relocated from vulnerable areas nationwide. Mandatory evacuations were enforced in provinces such as Camarines Sur, Catanduanes, Calabarzon, and Eastern Samar. In Quezon City, preemptive evacuations were conducted to ensure residents' safety. The Land Transportation Franchising and Regulatory Board (LTFRB) suspended bus travel to the Bicol region, and numerous flights and sea voyages were canceled to mitigate potential risks.
Impact and Damage
Man-yi made its first landfall in Panganiban, Catanduanes, on November 16, 2024, bringing with it torrential rains, destructive winds, and significant storm surges. The typhoon caused extensive damage across several regions:
Catanduanes: The province experienced severe infrastructural damage, with numerous homes destroyed, power lines downed, and widespread flooding reported.
Nueva Vizcaya: A tragic landslide in Ambaguio town resulted in the deaths of seven individuals, including children, and left three others injured. Rescue operations were launched to locate additional missing persons feared buried under the debris.
Camarines Norte: A 72-year-old man lost his life in a vehicular accident caused by hanging cables due to the storm's strong winds.
Overall, the typhoon affected more than a million people, with nearly 700,000 displaced from their homes. Approximately 8,000 houses were damaged or destroyed, and over 100 cities and towns experienced power outages due to toppled electric posts.
Government and International Response
In the aftermath of Man-yi, both national and international entities mobilized to provide aid and support:
Philippine Government: President Ferdinand Marcos Jr. expressed deep sorrow over the casualties and emphasized ongoing rescue and relief efforts. The government coordinated with local agencies to ensure the delivery of essential supplies and services to the affected regions.
International Assistance: The United States, through Defense Secretary Lloyd Austin, pledged an additional $1 million in humanitarian aid for typhoon victims. Austin authorized U.S. troops to assist Filipino forces in providing lifesaving aid. Other countries, including Singapore, Malaysia, Indonesia, and Brunei, also extended support, deploying cargo aircraft and other resources to aid in relief operations.
Environmental and Agricultural Impact
The series of back-to-back storms, culminating with Man-yi, had a profound impact on the Philippines' environment and agriculture:
Flooding: In rice-producing provinces like Nueva Ecija, extensive flooding submerged farmlands and villages, raising concerns among farmers about crop damage and potential food shortages. The floodwaters, exacerbated by the typhoon and surrounding provinces' runoff, made living conditions challenging for residents.
Cumulative Damage: The unprecedented frequency of storms within a short span led to compounded destruction. Prior to Man-yi, Tropical Storm Trami and Typhoon Kong-rey had already caused significant damage, with 162 fatalities and 22 individuals still missing. The successive nature of these calamities strained the country's disaster response mechanisms and highlighted the need for enhanced resilience strategies.
Climate Change Considerations
The occurrence of six major storms, including Man-yi, within a single month has raised concerns among scientists and policymakers about the potential influence of climate change on the frequency and intensity of such events. Climate experts emphasize the need for stronger disaster preparedness strategies, improved urban planning, and sustainable infrastructure to mitigate future risks associated with extreme weather phenomena.
