The weather office has meanwhile cautioned fishermen against venturing out to the South and Central areas of Bay of Bengal till October 9.
Under the influence of the low pressure, most places in Tamil Nadu registered moderate rainfall in the last 24 hours ending 8.30 am on Sunday, while Mimisal, a coastal village in Pudukottai district, received 13 cms of rainfall.
Sankarankovil and Ambasamudram received 8 cm each, Tiruppur and Tenkasi 7 cm each, while Kothagiri, Senkottai, Pudukottai and Tiruppuvanam each received 6 cm of rainfall, Balachandran said.

For Chennai and its neighbouring areas, there may be light to heavy rainfall in some places in the next 24 hours.
The prevailing climatic conditions favour the onset of the north-east monsoon in the state, Balachandran said.
The RMD deputy director general said the deep depression in the South Arabian Sea presently lay 920 km North West of Minicoy Islands of Lakshadweep and was expected to intensify into a cyclone in the next 24 hours and move towards Oman.
The Coast Guard has deployed Dorniers ships and its other formations have been put on high alert after issuance of warning by IMD regarding the formation of low pressure in South East Arabian Sea since October 1 and likely development into depression.
