Chennai woke up to sudden showers in various parts of the city on Wednesday morning and the rains are here to stay. The Northeast monsoon, which arrived in the state last week, was expected to intensify over Tamil Nadu on Wednesday.

According to weather blogger Pradeep John, who handles the popular Tamil Nadu Weatherman Facebook page, Chennai, Puducherry, Cuddalore, Nagapattinam, Thiruvarur, Karaikal, Ramanathapuram and Thoothukudi districts are expected to receive moderate rains on Wednesday. Parts of Theni, Virudhunagar, Thenkasi, Dindigul and Tirunelveli districts may receive heavy rainfall. This rainfall in Tamil Nadu is being brought by easterlies associated with convergence.

“Once day starts heating up, the easterlies will move in as the convergence shifts inland. So on a single day, you can see how the rains happen with the easterlies associated convergence (sic),” he wrote. Rainfall is expected to continue for the next four days followed by a brief break.

Interior parts of Ramanathapuram and Thoothukudi, Madurai, Virudhunagar, Tirunelveli, Thenkasi, Theni, Kanyakumari districts will also see good rainfall on Wednesday.
