during november 3, an area of low pressure developed over the bay of bengal, under the influence of active northeast monsoon conditions. on november 5, the imd identified the system as a depression and designated it with the identifier 'bob 04'. this was followed by the jtwc issuing a tcfa and subsequently initiating advisories on the system. the jtwc designated it '05b' and was reporting winds around the center on november 6. later that day, the imd upgraded bob 04 into a deep depression. the system drifted northwards over the next couple of days, maintaining its intensity. located between two subtropical ridges, bob 04 mostly showed quasi-stationary motion. however, albeit the adequately favorable conditions for further intensification, bob 04 failed to intensify further. this resulted in the imd downgrading the system into a depression and further into an area of low pressure by november 8.
