Northeast Monsoon has given some good rains over Kerala, Tamil Nadu and adjoining areas. However, the spread hasn’t been much. Now, week long rains are expected to be seen over many parts of South India. In fact, in addition to the five subdivisions that come under the Northeast Monsoon regime, the upcoming rains will also extend to Telangana and North Interior Karnataka. Simultaneously, it may give some rains over Goa and Mumbai as well.
Currently, a low pressure area over Southwest Bay off Tamil Nadu and Sri Lanka Coast. This particular system has a very slow movement and will persist for the next 2 days. Thereafter, the system will move westward. In addition to this, we expect the development of a Cyclonic Circulation over North Interior Karnataka and adjoining areas. This system will also stay for some time over that region.
