Unknown
Extratropical cyclone, remnant low, tropical disturbance, or monsoon depressionLate on July 23, an area of low pressure formed to the southeast of Chuuk.[1] the system gradually drifted to the west and on July 25, the JTWC upgraded the low pressure area to a tropical depression. At that time, it was located approximately 505 nautical miles (935 km; 581 mi) to the west of Guam.[2] At midnight, that day, the JMA started monitoring the system as a tropical depression.[3] Early on July 28, the JTWC upgraded the system into a Tropical Storm.[4] A few hours later, the JMA too upgraded the system to a tropical storm, naming it Muifa.[5] Soon, the storm moved into the Philippine Area of Responsibility (PAR) and the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) named it Kabayan.[6] The storm gradually drifted north over the next day maintaining strength. On the night of July 29, Muifa was upgraded into a Severe Tropical Storm.[7] Overnight, the storm strengthened rapidly and was upgraded into a Typhoon the next morning.[8] The storm strengthened so rapidly and the JTWC, reported that the storms peak winds were reaching 140 knots (260 km/h; 160 mph) (1-min sustained). However, the typhoon couldn't maintain strength for a long time. According to the JTWC, On July 31, the typhoon interacted with an upper level trough and weakened into a Category 4 Typhoon on the SSHS.[9]
