On June 15, TSR issued their pre-season forecast, predicting a neutral typhoon season. Predicted tropical storm numbers have decreased to 26, but both their predicted typhoon and intense typhoon numbers have increased to 18 and 9, respectively. The key factor to this prediction is now due to the anticipated neutral value for the August–September SST forecast in the Niño 4 region (5°S – 5°N, 150°W – 160°E) of +0.27 °C.

on July 8. Moving northwestward, the system gradually intensified, and the PAGASA began initiating advisories on 18:00 UTC of the same day, naming the system, ''Gorio''. Six hours later, the JTWC already deemed the system as Tropical Depression 07W. Deep convection persisted to the west of its well-defined, but a partially exposed center. Thus, the system gained strength into a tropical storm, with the JMA naming it as ''Trami''. Northeasterly shear prevented the storm to significantly intensify, and therefore Trami maintained tropical storm intensity for a day — only peaking with 10-minute sustained wind speeds of 75 km/h (45 mph). By 12:00 UTC of July 11, Trami moved over

on December 10. By 12:00 UTC of the same day, the JTWC upgraded the system to Tropical Depression 31W. Satellite imagery and animations showed that there were multiple centers within the large-scale center, which made it difficult to track. By December 12, the system finally gained convection near its center. 31W briefly reached tropical storm intensity by the JTWC on 18:00 UTC of the same day. The storm was still difficult to track, which made one warning relocating the storm's center near the island of

. However, after post-analysis, this center was a newly developed center that originated from the same surface trough of 31W. This new center eventually became Tropical Storm Faxai.
Typhoon Faxai
On December 13, a tropical depression formed in the open waters of the West Pacific. It drifted for 5 days, slowly organizing into a tropical storm on the 15th. As Faxai moved more quickly to the northwest, its wind speeds increased, becoming a typhoon on the 20th and rapidly intensifying to a peak of on the 23rd. Cooler waters and upper-level shear weakened it until it became extratropical on the 25th. Faxai, the strongest storm of the year, was one of the most intense December typhoons ever recorded. Fortunately, it never approached land.
Initially Faxai was classified as part of Tropical Depression 31W, but post-analysis considers the early part of Faxai's life a separate storm. As such, Faxai was classified as 33W in post-analysis.
Two people were killed as a result of the storm and damage across several islands amounted to roughly $1 million.
Faxai was the most intense tropical
worldwide in 2001.
