Chennai: The Meteorological Department has said that today (Oct. 21), very heavy rain may occur at one or two places in 3 districts, including Thoothukudi, and heavy rain may occur in 19 districts in Tamil Nadu.
Regarding this, a press release issued by V.R. Durai, senior official and scientist at the Chennai Meteorological Department, said: An atmospheric circulation persists over the southwest Bay of Bengal and the adjoining Tamil Nadu coastal areas. Due to this, there is a possibility of a low-pressure area forming in the same region within the next 24 hours.
Furthermore, a low-pressure trough persists up to the North Coastal Andhra region. As a result, on Oct. 21 (today), heavy to very heavy rainfall may occur at one or two places in the three districts of Thoothukudi, Tirunelveli, and Kanyakumari.
