Northeast monsoon activity has picked up over all the five sub divisions of South Peninsula, for the last 4 days. Weather activity extended further to the neighbouring sub divisions of Telangana, Madhya Maharashtra, Konkan & Goa, Coastal Karnataka and North Interior Karnataka for the last 48hours. Locations like Cannur, Kavali and Goa have been lashed with 100mm rainfall in 24 hours. During last 24 hours, heavy rains have lashed both coast and interiors of Tamil Nadu and Kerala. Konkan, Madhya Maharashtra, North Karnataka and Telangana were drenched with moderate to heavy showers at many places.
Chief amounts of rainfall, outside the monsoon sub divisions include : Sangli, Satara, Sholapur, Kolhapur in Madhya Maharashtra ; Gadag, Chitradurga, Mangalore in Karnataka; Nizamabad, Rentachintala, Mahabubnagar, Hyderabad in Telangana; Mahabaleshwar, Matheran, Mumbai in Konkan region. Weather activity is likely to continue over next 48 hours and reduce thereafter. Spread and intensity of rains will be higher in the eastern half of South Peninsula covering Madhya Maharashtra, Konkan & Goa, Kerala and interiors of Tamil Nadu. Chennai, Bengaluru and Thiruvananthapuram are expected to have moderate thundershowers over next 24 hours.
There are two weather systems responsible for these bursts of northeast monsoon. A cyclonic circulation is marked over the East-Central Arabian Sea, off the Kerala-Karnataka coast. Another cyclonic circulation is traced over the Comorin region. The combined influence of these features is keeping the monsoon active over southern parts. Typical monsoon activity will last for the next 48 hours and reduce later on. Very limited activity is expected around Diwali. Light spells of intermittent rain will be confined to South Coastal Tamil Nadu and the southern tip of Kerala on Sunday, 12thNov. Rest parts of the country can enjoy festivities without weather playing spoilsport.
