Presently,the axis of Monsoon trough has shifted northwards to its normal position. Moreover; there was no significant Monsoon system. Thus, the Monsoon surge remained weak over the west and central and pockets of South India.

In such scenario, Coastal Andhra Pradesh, Rayalaseema and Tamil Nadu have a tendency to record few spells. On a similar note, both Andhra Pradesh, particularly the coastal zone and Tamil Nadu have recorded light Monsoon rains in the past 24 hours.
Now, there is trough seen running from Coastal Andhra Pradesh up to Tamil Nadu. Along with this, a feeble cyclonic circulation can be seen in mid-levels off Andhra Coast in Bay of Bengal.
Under the impact of these weather systems, we are expecting rain and thundershowers of light to moderate intensity over Coastal Andhra Pradesh, Rayalaseema and North Tamil Nadu inclusive of Chennai. However, heavy rains are not on the cards for the stated regions.
These showers are most expected to persist at least during the next 24 hours. Thereafter, we are of the view that a weather system will develop in Bay of Bengal, reactivating the Monsoon surge. Consequently, the rains will abate Coastal Andhra Pradesh, Rayalaseema and North Tamil Nadu during the next 48 hours.
As on July 3, division-wise; Tamil Nadu has witnessed excess rains of 61%, Coastal Andhra Pradesh 16% and Rayalaseema 2%.
