Chennai: A cyclonic storm is likely to develop over the Bay of Bengal within the next two days, with weather models continuing to indicate a possible landfall along the Andhra Pradesh coast, potentially bypassing Tamil Nadu. The system will be named Akvan once it intensifies into a cyclonic storm. IMD’s latest track forecast indicates that it could strengthen into a severe cyclonic storm over the Bay around Nov 18, though a landfall location has not yet been specified.Rain activity over Tamil Nadu is likely to remain subdued until Nov 20, with light to moderate spells mainly over isolated parts of the Western Ghats and southern districts. Chennai may get occasional light spells.On Sunday, the city and its suburbs may get light rain in some areas. The maximum temperature is likely to be 33°C and the minimum around 24°C, an IMD bulletin said.However, bloggers said some weather models indicate a gradual southward shift in the cyclone’s track, which could improve rainfall prospects for Chennai and neighbouring districts. A southward shift could bring the system’s outer rain bands closer to the coast, triggering rainfall even if its centre remains over Andhra Pradesh.“Let’s wait for another two days to get more clarity. Models show slow southward shifting towards Nov 18-19,” said blogger Pradeep John.
