 The active monsoon spawned a low pressure area in the central Bay of Bengal on October 12 . The system had an area of convection about 925 km ( 575 mi ) southeast of Kolkata , which moved slowly westward . By October 14 , there was an exposed circulation center east of the convection , although it organized enough for the IMD to classify it as a well @-@ marked low pressure area . On October 15 , the agency classified it as a depression as the circulation moved closer to the thunderstorms . Later that day , the JTWC issued a TCFA and the IMD upgraded it to a deep depression , based on improving outflow and organization . On October 16 , a nearby ship reported winds of 65 km / h ( 40 mph ) , and that day the JTWC began tracking the system as Tropical Cyclone 01B . Early the next day , the IMD followed suit and upgraded the deep depression to a cyclonic storm , estimating peak winds of 65 km / h ( 40 mph ) . However , the system persisted in an area of weak to moderate wind shear , preventing further development . The circulation became exposed from the convection , and the wind shear increased . On October 18 , the IMD downgraded the system to a deep depression , and the storm dissipated on the next day as it approached the eastern coast of India .
