The twentieth named storm of the annual typhoon season, Trami developed into a low-pressure area and later into a tropical depression west of Guam on October 19, moving westward along the southern periphery.

Early the next day, the Japan Meteorological Agency (JMA) upgraded the system to a tropical storm, naming it Trami, as spiral bands of deep convection formed around the low-level circulation.

The following day, Trami emerged over the coastal waters of southern Ilocos Sur, with surface observations and radar data indicating a lee-side jump had occurred with its mid-level rotation surviving into the eastern South China Sea, leaving the remnants of its circulation center over Northern Luzon; later, satellite imagery revealed a consolidating central dense overcast, indicating a well-defined circulation with deep convection located to the south.

By late October 26, both the JMA and the Joint Typhoon Warning Center (JTWC) reported that Trami had reached its peak intensity, with sustained winds of 110 km/h (70 mph) over 10 and 1-minute intervals, and a central pressure of 970 hPa (28.64 inHg).

The storm made landfall the next day in Thua Thien-Hue and Da Nang and moved near the Laos–Vietnam border, where its circulation center became fully exposed before making a U-turn and gradually shifted back toward the coastal regions of Vietnam.

Coastal areas of Hainan Province in South China issued a red alert, the highest warning level, due to an approaching storm, forcing over 40,000 people to evacuate.

Strong winds in Da Nang, toppled trees and billboards, while heavy rainfall in Quang Tri province caused severe flooding, leaving 18,000 people without power.

The origins of Severe Tropical Storm Trami can be traced back to October 19, when the Japan Meteorological Agency (JMA) reported a low-pressure area located 633 km (394 mi) west of Guam.

[9] At 18:00 UTC that day, the JMA upgraded the system to a tropical storm and named it Trami,[10] with spiral bands of deep convection starting to wrap around the low-level circulation.

[20] The following day, Trami emerged over the coastal waters of southern Ilocos Sur,[21] with surface observations and radar data revealing that the storm had undergone a lee-side jump,[22] leaving the remnants of a circulation center over Northern Luzon while mid-level rotation shifted slowly westward into the eastern South China Sea;[23] later, satellite imagery showed a consolidating CDO, indicating a well-defined circulation with most of the deep convection situated to the south.

[26] By late October 26, both the JMA and JTWC noted that Trami had reached its peak intensity,[27] with sustained winds of 110 km/h (70 mph) over 10 and 1-minute intervals, and a central pressure of 970 hPa (28.64 inHg).

[30] It made landfall in Thua Thien-Hue and Da Nang at about 10 AM local time on October 27,[31] before drifting slowly inland while moving southwestward over the past few hours.

[51] Officials from Batanes and Ilocos Norte expressed concern about the potential for further damage to their provinces due to the expected impact of the storm, especially since these areas were still recovering from Typhoon Krathon (Julian) in 2024.

[82] On October 23, the Central Weather Administration issued heavy rain warnings for the Greater Taipei and Yilan–Hualien areas despite Trami not expecting to directly affect Taiwan.

[92] Officials in Naga said that around 700 mm (28 in) of rain fell on the city, equivalent to 2.5 months of average precipitation, causing floods from the Bicol River basin that affected 30% of its territory and 70% of its population.

[102] At least 6,034 people were evacuated in the province, while the Batangas Provincial Hospital in Lemery halted patient admissions after floodwaters entered its wards and emergency room,[103] and a landslide occurred in Talisay, resulting in 20 fatalities.

[109] Landslides blocked roads in San Mariano, Isabela[110] and Calanasan, Apayao, while strong winds were experienced in Laoag, Ilocos Norte, and heavy rainfall and flooding were reported in Pili, Camarines Sur.
