It is very likely to intensify further into a cyclonic storm over west-central Bay of Bengal subsequently, the Met Centre predicted.

There will be no major weather but there is possibility of isolated rainfall activity over Odisha upto October 23 morning.

Speaking to reporters, IMD DG Mrutyunjay Mohapatra said the prevailing weather system is likely to take the shape of a cyclone around October 23 or 24.

However, he said: "We have not predicted the intensity and possible area of landfall of the impending cyclone as it is yet to take the shape of a low pressure area."

The IMD is closely monitoring the system, he added.
