The JTWC then reissued a TCFA on the system while it was 233 km (145 mi) northeast of Davao City, Philippines. At 18:00 UTC, the JTWC upgraded the system to Tropical Depression 01W based on surface observations from Guiuan. Aghon made its first landfalls over Homonhon Island, Giporlos, and Eastern Samar in the early morning of May 25 (PHT). At 12:00 UTC, the JTWC reported that the tropical depression had intensified into a tropical storm while it was still in Tayabas Bay. 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. The JMA then classified the system as a tropical storm at 00:00 UTC of the following day, assigning it the name Ewiniar. In the morning of May 26 (PHT), the storm made its 8th landfall over Lucena, Quezon in Luzon island; nonetheless, the system developed a small dense overcast holding a ragged, formative eye. The JTWC then reported that Ewiniar had rapidly intensified into a typhoon due to strong equatorward and poleward outflow. In the evening, the storm made its ninth landfall over Patnanungan in the Polillo Islands; however, the outermost deep convective was diminishing because of the topographical effects from Luzon island, and the further development of a poleward outflow channel. Ewiniar then turned northwestward along the northwestern edge of a mid-level subtropical high.

Soon after, the JMA upgraded Ewiniar to a severe tropical storm at 18:00 UTC on May 26 as its maximum sustained winds increased to 95 km/h (60 mph). On the following day, Ewiniar intensified into a typhoon, according to the JMA, making it the first typhoon of the 2024 Pacific typhoon season; although its structure consolidated, the system's pinhole eye became obscured by cirrus clouds. At 06:00 UTC, the JTWC estimated maximum 1-minute sustained winds of 175 km/h (110 mph), equivalent to a Category 2 hurricane, though it was slightly weakening as a result of moderate wind shear. Infrared satellite imagery showed a partially-exposed circulation center with deep convection over the southern portion of the storm; however, Ewiniar maintained its convective symmetric structure as it accelerated northeastward. On May 28, the JMA recorded maximum sustained winds of 130 km/h (80 mph) and a minimum barometric pressure of 980 hPa (28.94 inHg) as the system's peak intensity. The storm then deteriorated from subsidence from a mid-latitude trough aloft as evidence by the structure's erosion and warming cloud tops. The center was still well-defined, as its outflow was enhanced by a longwave trough, though wind shear was moderate.

At 12:00 PHT (04:00 UTC) on May 29, the typhoon left the PAR. Shortly afterwards, it passed directly over the island of Minamidaitōjima. At 06:00 UTC, Ewiniar had weakened into a severe tropical storm. Environmental conditions became more unfavorable as sea surface temperatures decrease and vertical shear increases, as dry air invaded the system from the lower troposphere. Stratocumulus cloud lines went towards the elongated central convection due to this while the storm accelerated along the subtropical ridge to its northeast, weakening into a tropical storm as according to the JTWC. On May 30, the JTWC reported that Ewiniar had began losing its tropical characteristics while 719 km (447 mi) east-northeast of Kadena Air Base in Okinawa, Japan. Moreover, the JMA downgraded Ewiniar to a tropical storm at 06:00 UTC. The storm then developed a cold front to its southwest as deep convection detached from the fully-exposed and asymmetrical center, briefly becoming a subtropical cyclone. By 18:00 UTC on that day, the JMA reported that Ewiniar had transitioned into an extratropical low. The JTWC then ceased issuing advisories on the system as it entered the baroclinic zone and an area of high wind shear.
