The system was then located just south of a 250-hPa ridge axis, in a diffluent region.

There was a fluent-given target, fluent-new target, diffluent-given target, and a diffluent-new target.

There was a fluent-given target, fluent-new target, diffluent-given target, and a diffluent-new target.

Soon, the Joint Typhoon Warning Center ( JTWC ) issued a Tropical Cyclone Formation Alert on the system, for the consolidating and slightly better defined low-level circulation center, favorable sea surface temperature, moderate vertical wind shear, as well as highly diffluent outflow.

On November 13, IMD upgraded the system to a depression and designated it as " BOB 05 " at 00 : 00 UTC . The low-level circulation centre became fully exposed but well-defined on November 14, and deep convection was sheared to the northwest by moderate vertical wind shear which was offsetting easterly diffluent outflow.
