"Northeast monsoon rains have commenced over coastal Tamil Nadu and Puducherry, south Tamil Nadu, southern Kerala and southern coastal areas of Andhra Pradesh," he said.

The monsoon will cover the remaining parts of Tamil Nadu and Kerala, Rayalaseema and southern Karnataka on Friday, he added.

According to Indian Meteorological Department (IMD), the long period average rainfall for Tamil Nadu during the north east monsoon stretching between October and December was 44 centimetre and this time there could be an excess rainfall.

The forecast was for an "above normal" monsoon, it said adding "there are still two months left."

Balachandran predicted showers in most parts of the state and Puducherry on 2 and 3 November, while heavy rain was likely in one or two places in coastal districts.

There would be occasional spells of rains or thundershowers in Chennai and its suburbs, he added.

In the last 24 hours in Tamil Nadu, Puzhal recorded 11 centimetre rainfall while Kelambakkam recorded 10 centimetre.
