Fairly widespread moderate to light rainfall has been going on over the entire East Coast, from North Tamil Nadu to Odisha, during last 2 to 3 days. The intensity of rain was heavy to very heavy over Coastal Andhra Pradesh due to the cyclonic circulation which has now induced a low pressure area over Bay of Bengal off South Odisha and North Andhra Coast.
Till June 27, 5 subdivisions of the country have received excess rains this season. Among them, Coastal Andhra Pradesh has received 58% excess rains and Rayalaseema received 80% excess rains. Along the East Coast, Tamil & Puducherry is the other region to receive excess rains to the tune of 34%.
The other two excess rainfall pockets are North Interior Karnataka (35%) and Sub Himalayan West Bengal and Sikkim (23%).
Looking at the figures above, we can conclude that Andhra Pradesh is by far the best performing region. This state is the most preferred pocket for good rainfall activities as and when any Monsoon system develops over the Bay of Bengal.
The prevailing low pressure area near the Andhra coast will intensify further into a well-marked low pressure area and move in a west/ northwest direction. Therefore, we expect moderate to heavy rainfall over Coastal Andhra Pradesh, South Coast of Odisha and South Chhattisgarh.
The rainfall intensity over Tamil Nadu coast will reduce gradually as the moisture and wind concentration will revolve around the low pressure area.
Northern parts of Odisha will continue to receive light rain and thundershowers for another 2 days. Most parts of the East Coast will remain active for another 24 to 36 hours. By June 29, rain intensity will start reducing over Coastal Andhra Pradesh and Odisha as the weather system will move inland and start affecting Telangana, Vidarbha, Marathwada and East Madhya Pradesh.
