the typhoon accelerated, obtaining a forward speed of . During the afternoon of January 10, Roy reached its peak intensity as a low-range Category 4-equivalent typhoon on the Saffir–Simpson hurricane scale, attaining peak winds of . At the same time, the JMA estimated that the storm attained peak winds of along with a barometric pressure of 940 mbar (hPa; ). Upon reaching this strength, the storm was situated roughly east-southeast of Guam. Over the following few days, Roy gradually slowed and weakened as it neared the Mariana Islands. The storm made its closest approach to the islands early on January 12, passing within south of Rota. As the storm passed through the region, a new ridge built east of the typhoon, causing Roy to temporarily track southwestward before resuming a westward movement. Moving along the southern edge of the ridge, Roy accelerated again as it headed towards the Philippines. On January 14, the storm crossed 135°E, prompting the Philippine Atmospheric, Geophysical and Astronomical Services Administration to issue advisories on Roy, assigning it with the local name Asiang. As it neared the country, wind shear began to increase, resulting in further weakening. On January 16, Roy made landfall in the Bicol Region as a minimal typhoon before succumbing to shear and increased friction with the mountains of the Philippines. Later that day, the system weakened to a tropical storm before entering the South China Sea. The JTWC downgraded Roy to a tropical depression during the afternoon of January 17 and ceased issuing advisories early the next day. However, the JMA continued to monitor Roy as a tropical storm until the morning of January 18 and declared the system dissipated early on January 19, at which time the depression was situated roughly east-northeast of Ho Chi Minh City, Vietnam. Preparations and impact On January 8, Roy passed near the Majuro island chain in the Marshall Islands as a minimal tropical storm. Sustained winds of and gusts up to affected the area, resulting in minor structural damage. Later that day, the intensifying storm passed close to Kwajalein Atoll, bringing strong winds and large swells. Moderate structural damage took place on Kwajalein Island where winds gusted up to . Just to the north, more severe damage was recorded on Ebeye Island where low-lying areas were inundated by waves between . Approximately one third of the homes on Ebeye were destroyed by the storm.
