It then underwent an eyewall replacement cycle, then reintensified to attain 1-minute sustained winds of 305 km/h (190 mph) according to the JTWC, becoming a Category 5-equivalent super typhoon.

Mawar weakened slightly as it moved around the southwestern edge of the subtropical high that made it steer north of the Philippines and then east of Taiwan.

Mawar traversed the Okinawa Islands as a tropical storm, then transitioned into an extratropical cyclone as it moved northeastward out to sea, where it later dissipated east of Kamchatka Peninsula.

[32] On May 27, Mawar slightly weakened under the influence of dry air while moving west along the southern edge of a subtropical high.

During that time, Mawar was situated in an area where the sea surface temperatures were 28 °C (82 °F), indicating a cooling trend as the storm's outflow became impacted by it.

[84] A United States Geological Survey rain gauge in Dededo, Guam measured the most rainfall at 28.42 inches (722 mm).

[86] However, the typhoon's powerful winds did defoliate and uproot trees, topple billboards, and tear tin roofing from buildings.
