Why is rain expected now?

Meteorologists attribute this weather pattern to cyclonic circulation, which is drawing moisture from the Bay of Bengal into the mainland. At the same time, western disturbances remain active over northwestern India. Together, these systems have created favourable conditions for rain and thunderstorms across Bengal.
