Chennai, Jan 12 || The India Meteorological Department (IMD) has forecast heavy rainfall in seven districts of Tamil Nadu on Monday, as an atmospheric low-pressure system continues to prevail over the southern coastal region of the state and the adjoining Gulf of Mannar.
The weather system is expected to trigger intense showers across parts of the Cauvery delta and surrounding regions, prompting authorities to advise caution.
According to the IMD, districts likely to receive heavy rainfall today include Cuddalore, Ariyalur, Mayiladuthurai, Thanjavur, Tiruvarur, Nagapattinam, and Pudukkottai.
The Karaikal region in the union territory of Puducherry is also likely to experience spells of heavy rain during the day.
Meteorologists attributed the weather activity to a persistent low-pressure trough over the southern Tamil Nadu coast, which is drawing in moisture-laden winds from the sea. The rainfall is expected to be particularly significant in low-lying and delta regions, raising concerns over waterlogging in urban pockets and inundation of agricultural fields.
