Chennai: After two days of dry weather, Chennai and many parts of Tamilnadu will witness good rain again from today as a cyclonic circulation has formed over Gulf of Mannar. Not only that, the Met Department said two other low pressure areas are also prevailing over the bay, increasing chances of rainfall.

An official said, "A cyclonic circulation has been formed over Gulf of Mannar. Yesterday's low pressure area over south Andaman sea and adjoining Malay peninsula has moved towards the Indian coast and is lying over southeast Bay of Bengal. Also another upper air cyclonic circulation is prevailing over northeast Bay of Bengal. So, heavy rain is likely to occur in some places of coastal Tamilnadu and Puducherry, including Chennai from today till Monday. On Sunday, the city may witness heavy rain."

The rain has brought down the temperature not only in Chennai but many other parts of Tamilnadu. Places in the westernghats are witnessing all-time low temperatures accompanied by fog.

The official said, "Fog is likely to occur at a few places over the hill ranges of Nilgiris and Dindigul districts."

In Chennai, Met Department said the sky condition is likely to be generally cloudy. Rain or thundershower is likely to occur in some areas.

"Maximum and minimum temperatures were 31.2 and 23.4 degrees Celsius. Temperatures witnessed a rise of about 1 degree Celsius from normal. Relative humidity was quite high at 92 per cent," he added.

Regarding the rainfall in the last 24 hours, he said, "Thuckalay recorded a maximum rainfall of 5 cm, followed by Mylaudy which recorded 4 cm. Ambasamudram recorded 3 cm. Karaikal and Kalugumalai recorded 2 cm each. Papanasam, Tarangambadi, Nanguneri, Shencottah, Colachel and Periyar recorded 1 cm each."


Skymet forecast says a low pressure area is prevailing over southwest and adjoining southeast Bay of Bengal. This weather system will gradually move towards Tamilnadu and may intensify further into a well-marked low-pressure area.

Therefore, we expect the intensity of rain to increase gradually over coastal areas of Tamilnadu, says the weatherman.

Today, there will be light rain but the weather will remain cloudy. It is anticipated that the intensity of rain will increase from tomorrow. Rain will continue intermittently till November 15.

During this time, a few heavy spells are expected which may once again lead to waterlogging in many parts of the city, cautions Skymet.

After 15 November, the weather system will start moving in a north-northeast direction, away from Tamilnadu coast, towards Odisha and Gangetic West Bengal.
