Late on November 1 , a large eye redeveloped , and the JTWC estimated Krosa attained peak 1 minute sustained winds of 185 km / h ( 115 mph ) . Early the next day , the JMA also estimated the typhoon reached peak 10 minute winds of 140 km / h ( 85 mph ) . Later , increasing wind shear caused the eye to deteriorate , and Krosa began slowing about 260 km ( 160 mi ) east @-@ southeast of Hong Kong after reaching the western edge of the subtropical ridge . After remaining nearly stationary , Krosa began moving steadily to the west @-@ southwest due to a new ridge .

Also on November 4 , the JMA downgraded Krosa to tropical depression status off the northeast Vietnam coast . The system dissipated at 0000 UTC on November 5 .
