Chennai weather: Chennai and Thiruvallur are likely to receive extremely heavy rain, with maximum temperatures around 27 degrees Celsius.

Chennai has been placed under a red alert as a deep depression, the remnant of Cyclonic Storm Ditwah, over the west-central and adjoining southwest Bay of Bengal, near the north Tamil Nadu and south Andhra Pradesh coasts, triggers extremely heavy rainfall across several Tamil Nadu districts. The India Meteorological Department (IMD) has also issued a red alert for Thiruvallur on Tuesday.

According to the weekly forecast, Chennai and Thiruvallur are likely to receive extremely heavy rain, with maximum temperatures around 27 degrees Celsius and minimum temperatures near 23 degrees Celsius.The weather system is likely to recurve towards the southwest and is expected to weaken into a depression within the next 12 hours. “The minimum distance of the centre of the deep depression from the north Tamil Nadu–Puducherry coasts is about 35 km. It is very likely to recurve slowly southwestwards and weaken into a depression during the next 12 hours,” the IMD said.
