An official from Chennai Meteorological Centre explained that the low pressure zone formed over the bay of Bengal has now stabilised over the ocean near Kanyakumari. Hence, it has been raining for the last 24 hours.
There may be wide-spread rains in several districts including Chennai, Thiruvallur, and Kanchipuram and interior distracts. Rain may gradually abate in the northern districts.
There are prospects for heavy rains in the Southern Tamil Nadu coastal and delta districts.
