Typhoon Roy (International designation: 198801; Joint Typhoon Warning Center (JTWC) designation: 01W; PAGASA designation: Asiang) was the second-most intense January tropical cyclone on record in the Western Pacific basin. Forming out of an area of disturbed weather on January 7, Roy quickly intensified as it moved through the Marshall Islands. By January 9, the storm intensified into a typhoon and attained its peak intensity the following day. At its peak, sustained winds reached 215 km/h (135 mph). Slight weakening took place before the storm moved through the Mariana Islands. Continuing westward, the system eventually struck the Philippines as a minimal typhoon before dissipating over the South China Sea on January 19.
