 An area of disorganized thunderstorms was noted near 2N 159E on March 26 . Moving northwest due to significant cyclogenesis offshore Japan , a circulation center developed within this convective cluster over the next few days . By the afternoon of March 29 , it had matured into a tropical storm . A mid @-@ level trough extended southwest towards the cyclone . Combined with strong ridging building in north to northwest of the storm , Odessa ceased moving northwest and turned east at around 10 knots ( 19 km / h ) during March 30 and March 31 . As the mid @-@ level trough continued moving east , Odessa turned back to the north , and eventually west @-@ northwest , as ridging built in north of the cyclone . After the change in course to west , intensification resumed , and the system reached typhoon strength in the afternoon of April 2 . As Odessa peaked in strength a weakness in the subtropical ridge lured its convection northeast , shearing the thunderstorms away from the center . Rapid weakening ensued , and the cyclone dissipated on the afternoon of April 4 .
