 Similar to the previous storm , the active monsoon trough spawned a low pressure area over the Andaman Sea on October 24 . There was a weak center that had good outflow . On October 25 , the IMD classified the system as a depression about 925 km ( 575 mi ) southeast of Kolkata . The system moved to the northwest and developed more convection close to the center , although the thunderstorms were intermittent . Turning more to the north , the depression intensified into a deep depression and later cyclonic storm on October 27 , reaching peak winds of 65 km / h ( 40 mph ) ; the JTWC also classified it as Tropical Cyclone 02B . That day , the wind shear increased , although the convection was able to increase over the center and organize into a comma @-@ shaped rainband . Early on October 28 , the storm made landfall in southern Bangladesh near Mongla , by which time the wind shear had displaced much of the convection to the northeast . It rapidly weakened over land , degenerating into a remnant low over northern Bangladesh early on October 29 .
