The heavy overnight rainfall in Chennai has led to heavy inundation in southern pockets of Chennai. The Chennai Corporation has deployed boats for rescue and more than 500 giant pumps to flush out the water. The weather department has forecast very heavy to extremely heavy rainfall in the city. The depression is likely to cross between Sriharikota and Karaikal this evening. NDTV's Sam Daniel spoke to a resident and fire and rescue personnel at Ram Nagar where people wade through knee to waist-deep waters. Water has entered several homes too.
