Chennai: A low-pressure area is very likely to develop over the Equatorial Indian Ocean and the adjoining South-West Bay of Bengal around April 25, said a Meteorological Department official. He added that the low-pressure situation is very likely to intensify into a depression by April 27, move towards Tamil Nadu coast and intensify into a cyclonic storm by April 29, reported news agency ANI.
The weather department official in Chennai said, “Due to this cyclonic activity, moderate to heavy rain likely to occur over coastal Tamil Nadu & Puducherry 29th April onwards.” On the other hand, Skymet Weather agency stated that the depression which is expected over the Bay of Bengal may not move towards the Tamil Nadu coast and may not affect areas like Chennai.
“On April 29 and 30, it will move over the central and adjoining northeast Bay of Bengal. While on May 1, it would be close to the proximity of Bangladesh and Myanmar near the Arakan coast. The system would be moving in favourable weather conditions as Sea Surface Temperatures (SSTs) would be around 29 degrees Celsius that are conducive for the formation of cyclonic storms,” said Skymet Weather agency adding that “Despite all these favourable factors, this storm, the very first one of this season doesn’t seem intense in nature. When the monsoon current is strong/aggressive/active, it tends to suppress the cyclonic storm.”
According to IMD’s weather forecast, light to moderate rain is likely to hit isolated places in Tamil Nadu till April 27.
