After Typhoon Molave devastated the Philippines, the JMA announced the formation of a new tropical depression in the Pacific Ocean, west of the Mariana Islands, on October 27 UTC.[1] Given its proximity to the Philippine Area of Responsibility, along with its westward forecasted track, the PAGASA also began issuing advisories on the newly-formed system.[2] By the next day, the JTWC had also followed and upgraded the system into a tropical depression, giving it the designation 22W.[3] The storm had good outflow and structure as it approached the Philippine Area of Responsibility.[4]

As the system continued tracking westward under favorable conditions in the Pacific Ocean, the JMA and JTWC upgraded the system into a tropical storm, with the JMA assigning the name Goni to the intensifying storm.[5][6][7] The PAGASA followed with an upgrade to a severe tropical storm a few hours later.[8] Due to the warm waters surrounding the storm, the system underwent rapid intensification and became a typhoon.[9] On October 29 at 9:30 UTC, Goni entered the PAR and was named Rolly by the PAGASA.[10]
