More rains are expected in Chennai even as the city is reeling under the inundation and flooding caused by incessant rains on November 6. According to the India Meteorological Department, a low pressure area has formed over the southeast Bay of Bengal and the neighbourhood under the influence of cyclonic circulation.

The IMD on Tuesday, November 9, gave a red warning for Tiruvannamalai, Villupuram, Chennai, Chengalpattu, Kanchipuram and Tiruvalur. An orange alert was given for Nilgiris, Coimbatore, Tiruppur, Dindigul, Salem, Kallakuruchi, Tirupattur, Vellore and Ranipet. 

“Associated cyclonic circulation extends up to 4.5 km above mean sea level. It is very likely to concentrate into a Depression over the Southwest & adjoining Southeast Bay of Bengal during next 36 hours,” the IMD said. This, it added, was likely to reach the coast of north Tamil Nadu by the early hours of November 11. 

According to Pradeep John, who goes by the moniker Tamil Nadu Weatherman, a good spell is expected in Chennai from noon on November 9 which would increase from the night. However, he said that the worst of it — the period which will see the heaviest rainfall is expected to start on Wednesday, November 10 around noon and continue non-stop till noon on November 11. 

He added that the Vedaranyam-Thiruvarur belt which is already receiving incessant rainfall will continue to see heavy rains.·
