Flood Situation By Heavy Rain; Expected Over Chennai and Other Coastal Districts Of Tamil Nadu


The low-pressure area in the Bay of Bengal has undergone further intensification. Now the system has become a well-marked low. During the next 24 to 48 hours, the weather system may intensify even further. 
Due to this, rainfall activity has picked up in Chennai and the intensity of rain is expected to increase even further. Heavy rains may lead to flood-like conditions in many parts of coastal Tamil Nadu.
 The upper air cyclonic circulation over Andaman Sea has induced a low-pressure area in the Bay of Bengal. The system will move along the periphery of Sri Lanka giving heavy rain over the region. This low-pressure area will move in a north-westerly direction and gradually intensify into a well-marked low in the next 24 hours or so. The system may further intensify into a depression.
 November 15 night onwards, rainfall over coastal Tamil Nadu will increase. By November 16, fairly widespread heavy to very heavy rain is expected over Chennai and other coastal districts of Tamil Nadu including Kanchipuram, and Nagapattinam. Good rains will also occur over Puducherry. By November 17, most parts of Tamil Nadu including South Interior Karnataka and Kerala will receive light to moderate rain. A few areas will also receive heavy falls.
 This weather system is expected to cross the Arabian Sea by November 20. During that period, rainfall will reduce over Tamil Nadu but Kerala and western parts of Tamil Nadu will continue to receive light rain.
