Tropical Storm Ewiniar known in the Philippines as Severe Tropical Storm Aghon is an active tropical cyclone currently meandering Southern Luzon. The first named storm of the 2024 Pacific typhoon season. Ewiniar started as a disturbance southeast of Palau. It entered the Philippine Area of Responsibility on May 23 as it tracks eastwards. The next day, PAGASA reported that the disturbance became a tropical depression, giving the name Aghon, a replacement name for Ambo. Aghon continues to track over favorable conditions as it heads for a landfall in Homonhon Island. Overnight, Aghon made five more landfalls in Samar and some areas in Bicol. On May 25, the depression intensified into Tropical Storm Ewiniar as it headed for another landfall in Lucena, Quezon. Despite its slow movement, Ewiniar upgraded into a Category-1 typhoon as it headed northeast.

On May 21, the Joint Typhoon Warning Center (JTWC) began to monitor an area of atmospheric convection 441 km (274 mi) southeast of Palau, noting that the system 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 the following day, the Japan Meteorological Agency (JMA) labeled the system as a low-pressure area.[2] The JTWC 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.[3] At 18:00 UTC, the JMA recognized the system as a tropical depression.[4] Early on May 23, the depression entered the Philippine Area of Responsibility (PAR).[5] However, later that day, the JTWC cancelled their TCFA, since the depression was still weak.[6] Early morning of May 24, PAGASA upgraded the system from a low-pressure area into a depression, assigning it the name Aghon.[7] The JTWC then reissued a TCFA on the system while it was 233 km (145 mi) northeast of Davao City, Philippines.[8] At 18:00 UTC, the JTWC upgraded the system to Tropical Depression 01W based on surface observations from Guiuan.[9] Aghon made landfall over Homonhon Island and subsequently Giporlos, Eastern Samar in the early morning of May 25 (PHT).[10] In the evening, it made 5 more landfalls over Basiao and Cagduyong Islands of Catbalogan, Samar; Batuan, Masbate; Masbate City; and Torrijos, Marinduque.[11] At 12:00 UTC, the JTWC reported that the tropical depression had intensified into a tropical storm while it was still in the Tayabas Bay.[12] The JMA then classified the system as a tropical storm at 00:00 UTC of the following day, assigning it the name Ewiniar.[13] In the morning of May 26 (PHT), the storm made its 8th landfall over Lucena, Quezon in Luzon island.[14] JTWC upgraded Ewiniar into a Category 1-equivalent typhoon as satellite imagery shows that the eye feature developed over warm waters of Lamon Bay.[15]

Current storm information

Maximum 10-minute sustained winds are at 35 knots (65 km/h; 40 mph), with gusts up to 50 knots (95 km/h; 60 mph), while maximum 1-minute sustained winds are at 55 knots (100 km/h; 65 mph). The minimum central barometric pressure is 1002 hPa (29.59 inHg), and the system is moving north-northeast at 6 kn (11 km/h; 6.9 mph).
