Southwest Monsoon Update: Most of the country is now undergoing a dry spell except for occasional rains in one or two places. Southwest Monsoon will retreat from North West India in the next 1 or 2 days. Today could also see a dry day over most parts of the country except extreme South Peninsula. But a low pressure expected to evolve near North Andaman could once again trigger the rains for East India depending on how it manages to intensify. 
Parts of Southern Peninsula would continue to get good rains under the influence of the UAC in Central Bay. South Karnataka around Chamrajnagar, Mysore, Madikeri & Bangalore could get another good day of rains while Wayanad & Kozhikode districts of Kerala particularly the areas adjoining Nilgiris & Chamrajnagar region could get some good rains continuing from yesterday.
Tamil Nadu Weather Update: Under the influence of the evolving disturbance in the Bay cloudy skies could prevail over most parts of Tamil Nadu with temperatures showing a reduction compared to the last few days. In what could be another rainy day over Central & Western TN, parts of the Delta districts in Thanjavur, Tricy & Thiruvarur could get some spells of rains today. In the west parts of Erode, Tiruppur, Coimbatore & Nilgiris districts could get good rains. Particularly Nilgiris could receive heavy spells of rains occasionally. The North Coastal TN stretch between Chennai & Chidambaram could see some rains as well.
Chennai Weather Update: Cloudy skies mostly with temperature around 33°C. There is a good chance of late afternoon / evening rains over most parts of Chennai with the heavier spells along the Western & Southern suburbs.
