02B then moved slightly northwest as it attained its peak intensity of 50 mph, This was short-lived as strong upper-level shear began impacting the storm, gradually weakening it until making landfall 10nm (19 km) south of Balasore on October 14, before rapidly weakening overland and disspating that same day.

The disturbance moved slowly northwestward with little or no change in organization until November 9, when it finally developed into a tropical depression.

04B then rapidly weakened overland before restrengthening back into a tropical depression over the eastern Arabian Sea on December 2.

04B kept this intensity for a day as shear increased as it approached southern Somalia, making landfall as a dissipating tropical storm on December 7.
