Weathermen said the interaction could trigger heavier spells from Sunday night to Monday morning, before the city enters a likely break in rainfall. After that, dry weather may prevail for a few days,” he said. “The temperature may not be that high as it is not the season for that because the Sun has moved south of the equator,” Durai said.
Chennai: A drama could unfold over the Bay of Bengal as brewing cyclone Arnab threatens to pull the low-pressure area hovering over the Arabian Sea into its circulation, potentially bringing more rain to Chennai and neighbouring districts. A trough extending from the cyclonic circulation associated with the Arabian Sea system towards north coastal Tamil Nadu could further enhance rainfall.

On Monday, heavy to very heavy rainfall may be restricted to southern and western districts. V R Durai, director of the Area Cyclone Warning Centre at RMC Chennai, said the system over the east-central Bay of Bengal would draw the Arabian Sea low-pressure area, potentially bringing heavy rain to Chennai and neighbouring districts on Sunday.
From Oct 27 to around Nov 3, moisture is likely to be concentrated around the cyclone as it moves towards the south Andhra Pradesh-north Odisha coast, with landfall expected before it moves northwards towards Gangetic West Bengal. Dry weather may prevail over Chennai during this period, leading to a slight rise in daytime temperatures.
