official northern indian_ocean recognized issued warnings tropical cyclones developing region basin activity sub divided opposite coasts india generally split monsoon season utilized satellite imagery

extremely severe cyclonic storm storm season originated tropical disturbance formed east following days system gradually organized depression moved eastward coastline southwestern india rapidly

convection utc september upgraded system cyclonic storm estimating peak winds mph early september circulation moved beneath convection prompting begin advisories time storm outskirts dropped light rainfall western india forecasters initially anticipated storm strengthen winds mph strike southern persistent wind shear circulation convection weakening downgraded storm deep depression later depression september time thunderstorms rapidly issued advisory september circulation nearby convection time storm located east southeast downgraded depression low pressure area september noted remnant system poorly defined following day cyclonic storm similar previous storm area convection formed west southwest mumbai october associated circulation moved westward formed defined low pressure area western india convection organized increased aided low wind shear good outflow late october classified system depression early day upgraded deep depression low level circulation formed beneath defined mid level storm intense convection strong winds north center utc october began classifying system tropical cyclone increasing banding features storm strengthened moving west northwestward steered ridge north utc day upgraded system cyclonic storm estimating peak winds mph soon storm began weakening increased dry air upper level environment unfavorable thunderstorms diminished disappeared circulation october day discontinued advisories downgraded remnant low pressure area south pakistan storm brushed indian coast rainfall reaching state major damage cyclonic storm bob early

development associated southwest monsoon june low pressure area formed defined june time convection located west exposed circulation early following day classified depression estimating peak winds mph strong wind shear prevented development shortly forming system moved northwestward landfall near quickly weakened depression intensity june progressing inland remnant low near june system dropped heavy rainfall path daily peak november cycling area convection persistent east coast india associated broad circulation embedded trough thunderstorms expanded gradually organized aided good outflow low wind shear november upgraded system depression day began classifying depression located weakness ridge depression moved slowly north northeast initially expected ashore increasing shear removed
