B Amudha, deputy director general (addl charge), IMD, said two more atmospheric circulations may influence rainfall, one over Kanyakumari, which may trigger a low-pressure area over the region and adjoining southwest Bay and Sri Lanka on Tuesday, and another over the southeast Arabian Sea. 

“All three circulations may merge due to upper-air changes. We will have details in coming days,” she said. On Monday, weather models suggested the cyclone may move close to the Chennai coast on Nov 29 and 30, though forecasts differ on landfall with models showing the system crossing the AP coast or making a northward movement into the Bay of Bengal before weakening.

On Nov 29, rain may spread to north TN, with Mayiladuthurai, Cuddalore, Villupuram, Chengalpet, Chennai, Kancheepuram, Tiruvallur and Puducherry likely to receive heavy to very heavy rainfall.
