North coastal T.N., delta districts may receive heavy rains from Sunday

Another low pressure area over southeast Bay of Bengal and north Andaman Sea is likely to intensify into a depression on Saturday, the India Meteorological Department has said

The fresh weather system waiting in the wings is expected to bring heavy rains in north coastal Tamil Nadu and delta districts from Sunday.

A low pressure area that formed over southeast Bay of Bengal and north Andaman Sea this morning is likely to intensify into a depression over central parts of south Bay of Bengal by Saturday. It is expected to move towards Tamil Nadu, Puducherry and the south Andhra Pradesh coasts during the next three days.

This weather system may put an end to the short rain break that most of the State is experiencing this week, and influence an increase in rains from Saturday.

P. Senthamarai Kannan, Director, Area Cyclone Warning Centre, Chennai, said the prediction of the system’s movement is varied across different weather models. While some showed the north TN coast coming under it, some models indicated a movement towards the south AP coasts.

“We will have a better understanding of the track by Friday. We expect isolated very heavy rains to hit extreme north TN districts, including Kancheepuram, Chengalpattu and Villupuram districts, on Monday if the system moves upwards,” he said.

Tamil Nadu has so far received nearly 33 cm of rainfall, which is surplus by 14%, during this season, he added.
