Typhoon Ewiniar (2024): A Comprehensive Retrospective
1. Formation and Meteorological History
Typhoon Ewiniar, known in the Philippines as Typhoon Aghon, was the first tropical cyclone of the 2024 Pacific typhoon season. It originated from a tropical depression that formed near the equator on May 22, 2024. The system gradually intensified as it moved westward, becoming a tropical storm on May 24 and reaching typhoon status on May 26. Ewiniar peaked as a Category 2-equivalent typhoon on the Saffir-Simpson scale, with maximum sustained winds of 176 km/h (109 mph) and a minimum central pressure of 970 hPa. The storm tracked generally northwestward, making landfall in the Philippines on May 27 before recurving northeastward toward Japan. It weakened as it encountered cooler waters and strong wind shear, transitioning into an extratropical cyclone on May 31.
2. Impact and Damages
Philippines
Ewiniar struck the Philippines as a severe tropical storm, bringing torrential rains and strong winds to the eastern provinces. The storm triggered widespread flooding and landslides, particularly in the Bicol Region and Eastern Visayas. According to the National Disaster Risk Reduction and Management Council (NDRRMC), at least 6 people were killed, and over 100,000 residents were displaced. Agricultural damage was significant, with rice and corn crops destroyed, leading to an estimated economic loss of PHP 1.2 billion (USD 21 million). Infrastructure damage included damaged roads, bridges, and power lines, leaving several towns without electricity for days.
Japan
After exiting the Philippines, Ewiniar approached Japan as a weakening tropical storm. It brought heavy rainfall to the Ryukyu Islands and southern Kyushu, with accumulations exceeding 300 mm in some areas. Flooding and landslides were reported in Okinawa and Kagoshima prefectures, but no fatalities occurred. The storm disrupted transportation, with flight cancellations and ferry suspensions. Damage was relatively minor compared to the Philippines, with estimated losses of JPY 5 billion (USD 33 million).
Other Regions
Ewiniar's outer rainbands affected parts of Taiwan and China's southeastern coast, causing localized flooding but no major damage. The storm also contributed to the formation of Cyclone Remal in the Bay of Bengal, though no direct impacts were recorded.
3. Government Response and Relief Efforts
Philippines
The Philippine government, through the NDRRMC, activated emergency protocols ahead of the storm. Preemptive evacuations were conducted in high-risk areas, and relief goods were pre-positioned. After the storm, the Department of Social Welfare and Development (DSWD) distributed food packs and hygiene kits to affected families. The Department of Public Works and Highways (DPWH) deployed teams to clear debris and repair damaged infrastructure. The Philippine Coast Guard assisted in rescue operations. International aid was offered by several countries, including Japan and the United States.
Japan
The Japan Meteorological Agency (JMA) issued timely warnings and advisories. Local governments in Okinawa and Kyushu opened evacuation centers. The Japan Self-Defense Forces were placed on standby but were not deployed. Post-storm, cleanup and recovery efforts were swift, with minimal disruption to daily life.
International Coordination
The ASEAN Coordinating Centre for Humanitarian Assistance (AHA Centre) monitored the storm and facilitated information sharing. The United Nations Office for the Coordination of Humanitarian Affairs (OCHA) provided support to the Philippines. No major international relief operations were required.
Conclusion
Typhoon Ewiniar, while not a catastrophic storm, highlighted the vulnerability of the Philippines to tropical cyclones and the importance of preparedness. The storm's impact was largely confined to the Philippines, with Japan experiencing only minor effects. The response efforts demonstrated effective coordination between national agencies and international partners.
