Typhoon Ewiniar, known in the Philippines as Typhoon Aghon, is an active tropical cyclone currently meandering through northern Luzon. The first named storm and typhoon of the 2024 Pacific typhoon season. Ewiniar emerged from an area of atmospheric convection 441 km (274 mi) southeast of Palau. The Japan Meteorological Agency (JMA) labeled the system as a low-pressure area on May 21. It intensified the next day and became a tropical depression, giving it the name Aghon by the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) after entering the Philippine Area of Responsibility on May 23, marking it as the fifth-latest start of a Pacific typhoon season since reliable records began; the depression intensified into a tropical storm, assigning it the name Ewiniar. The cyclone made nine landfalls in the Philippines. Afterward, it began to move over the warm tropical waters of Lamon Bay, where the Joint Typhoon Warning Center (JTWC) and the JMA upgraded Ewiniar into a minimal typhoon. However, the outermost deep convective was diminishing because of the topographical effects of Luzon Island.

The Department of Public Works and Highways (DPWH) of the Philippines reported at least ₱320 million (US$6.5 million) in infrastructural damages. Maritime transport was greatly disrupted, with rough seas stranding over 7,175 people in various ports. Three people have been reported dead following the typhoon, another seven remain injured.

Typhoon Ewiniar (known locally as Aghon) emerged from an area of atmospheric convection 441 km (274 mi) southeast of Palau. The disturbance was moving northwestward towards an environment favorable for tropical cyclogenesis, characterized by sea surface temperatures of 29–30 °C (84–86 °F), low vertical wind shear, and moderate to strong outflow aloft associated with an upper tropospheric trough west of the system.[1] On May 22, the Japan Meteorological Agency (JMA)[nb 1] labeled the system as a low-pressure area.[2] The Joint Typhoon Warning Center (JTWC)[nb 2] subsequently issued a Tropical Cyclone Formation Alert (TCFA) as the disturbance developed rainbands wrapping from the southwest, with deep convection obscuring the system's consolidated circulation center.[4] At 18:00 UTC, the JMA recognized the system as a tropical depression.[5] Early on May 23, the depression entered the Philippine Area of Responsibility (PAR).[6] However, later that day, the JTWC cancelled their TCFA, since the depression was still weak.[7] Early morning of May 24, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) upgraded the system from a low-pressure area into a depression, assigning it the name Aghon, marking it as the fifth-latest start of a Pacific typhoon season since reliable records began.[8][9][nb 3]

Severe Tropical Storm Ewiniar beginning to move away from the Philippines during the evening of May 26.

The JTWC then reissued a TCFA on the system while it was 233 km (145 mi) northeast of Davao City, Philippines.[10] At 18:00 UTC, the JTWC upgraded the system to Tropical Depression 01W based on surface observations from Guiuan.[11] Aghon made landfall over Homonhon Island and subsequently Giporlos, Eastern Samar in the early morning of May 25 (PHT).[12] In the evening, it made five more landfalls over Basiao and Cagduyong Islands of Catbalogan, Samar; Batuan in Ticao Island; Masbate City; and Torrijos, Marinduque.[13] At 12:00 UTC, the JTWC reported that the tropical depression had intensified into a tropical storm while it was still in Tayabas Bay.[14] The JMA then classified the system as a tropical storm at 00:00 UTC of the following day, assigning it the name Ewiniar.[15] In the morning of May 26 (PHT), the storm made its 8th landfall over Lucena, Quezon in Luzon island; however, the system continued to develop a central dense overcast within the formative eye.[16] The JTWC upgraded Ewiniar into a Category 1-equivalent typhoon after satellite imagery showed that its eye feature was developing over the warm waters of Lamon Bay.[17][18] In the evening, the storm made its ninth landfall over Patnanungan in the Polillo Islands; however, at 21:00 UTC on the same day, the outermost deep convective was diminishing because of the topographical effects from Luzon island,[19] and the further development of a poleward outflow channel.[20] Ewiniar moved northeastward and then northwestward along the periphery of a mid-level subtropical high.[21] Soon after, the JMA upgraded Ewiniar to a severe tropical storm at 21:00 UTC on May 26 as its maximum sustained winds increased to 95 km/h (60 mph).[22] On the following day, Ewiniar intensified into a typhoon, making it the first typhoon of the 2024 Pacific typhoon season; however, it was slightly weakening as a result of moderate wind shear.[23][24] Infrared satellite imagery at 15:00 UTC showed a partially-exposed circulation center with deep convection over the southern portion of the storm.[25]

Current storm information[edit]

As of 18:00 UTC May 27, Typhoon Ewiniar (Aghon) is located near 18°06′N 124°54′E / 18.1°N 124.9°E / 18.1; 124.9 (Ewiniar) or about 566 nautical miles (1,050 km; 650 mi) south-southwest of Kadena Air Base. Maximum 10-minute sustained winds are at 65 knots (120 km/h; 75 mph), with gusts up to 95 knots (175 km/h; 110 mph), while maximum 1-minute sustained winds are at 80 knots (150 km/h; 90 mph). The minimum central barometric pressure is 985 hPa (29.09 inHg), and the system is moving north-northeast slowly.

Preparations[edit]

Philippines[edit]

Upon the system's designation as a tropical depression, the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) issued Tropical Cyclone Wind Signal No. 1 from Sorsogon, part of Albay, Catanduanes, part of Camarines Sur, Samar, Northern Samar, part of Leyte, the entire province of Surigao del Norte, and Surigao del Sur.[26] Ewiniar also raised Signal No. 1 alerts from the eastern portions of Bulacan, Nueva Ecija, Quezon, Laguna, Rizal, and Romblon, and the entirety of Aurora, Marinduque, Camarines Norte, Masbate, Eastern Samar, Southern Leyte, Bohol, Dinagat Islands, Agusan del Sur, and Agusan del Norte.[27] On May 23, PAGASA noted that heavy rain and landslides were likely across Samar.[28] Six domestic flights were cancelled.[29]

After Ewiniar reached severe tropical storm category on the afternoon of May 26, the agency raised Signal No. 3 in the eastern section of Quezon, including the Polillo Islands, while storm signals were also raised in Metro Manila and parts of Bataan, Batangas, Pampanga and Oriental Mindoro.[30] Moving northeastward and then intensified into a typhoon category, the agency raised Signal No. 1 in parts of Quirino, Nueva Vizcaya, Isabela, and Camarines Norte.[31] Classes and government work in some parts of Metro Manila, Aurora, Laguna, Quezon, Batangas, Cavite, and Nueva Ecija were suspended due to the typhoon.[32] The University of the Philippines Los Baños (UPLB) also suspended classes due to the inclement weather brought by Ewiniar.[33]

Japan[edit]

As the storm moved towards Japan, the Japanese government issued a high alert as Ewiniar was likely to enhance a stationary front near the nation, which would cause heavy rainfall throughout Japan.[34]

Impact[edit]

Tropical Storm Ewiniar intensifying over the Philippines during the morning of May 26.

Some flooding occurred in Misamis Oriental,[35] Eastern Visayas, and Bicol on May 25, causing a tree in Legazpi, Albay to fall down and injure three people.[36] A tornado also spawned in Lavezares, Northern Samar, destroying four houses and damaging eight others.[37] A passenger boat sank in stormy waters off the coast of Aroroy, Masbate, leading to the rescue of its 35 passengers and crew.[38] In Bicol, four people were injured and almost 6,000 people were stranded in ports after sea travel was suspended,[36][39] while 600 others were also stranded in ports in Eastern Visayas. A power outage occurred in parts of Eastern Samar.[40] A falling tree destroyed two vehicles in Taytay, Rizal.[41] Flooding and power outages occurred in Quezon and Laguna Provinces, while a barge ran aground in Mauban.[42][43] Around 7,175 were stranded in ports across the Philippines due to the storm.[44] A total of 21 homes were affected, including four which were totally destroyed.[45][46]

A state of calamity was declared in Lucena, Quezon.[47] As rains continued throughout the day, the Angat Dam reached its spilling level of 179.79 meters (589.9 ft), while the Ipo Dam also reached its spilling level of 99.96 meters (328.0 ft).[48] Nineteen houses were washed away by strong waves in Tanza, Cavite.[49] One infant drowned after a house was swept away by floods in Padre Burgos, Quezon,[50] while two others were killed by falling trees in San Antonio, Quezon and Lucena.[51] The Department of Public Works and Highways (DPWH) reported damage to infrastructure; estimated at ₱320 million (US$6.5 million).[52] Seven people were injured and around 19,000 others were directly impacted by Ewinar in the Philippines.[53][45] Nearly 12,000 people were displaced in Calabarzon alone.[54]

Aftermath[edit]

President Bongbong Marcos urged Filipinos to be vigilant as the storm affected the Philippines and announced the distribution of ₱1.2 million (US$24,365.48) in humanitarian aid to the typhoon victims.[55][56] The Department of Social Welfare and Development (DSWD) gave around one million pesos worth of aid to families affected by the typhoon.[57] As of May 26, 2024, the National Disaster Risk Reduction and Management Council (NDRRMC) reports that assistance and relief goods worth ₱591,190 (US$12,003.86) have been distributed to affected families.[45]
