Following Nivar, another cyclonic circulation is forming in the Indian Ocean and adjoining South Andaman Sea due to which extremely heavy rains can be expected around December 2 and 3 over Tamil Nadu and Puducherry, IMD has said.

Its latest update states that a cyclonic circulation lies over East Equatorial Indian Ocean and adjoining south Andaman Sea and extends up to 5.8 above mean sea level.

Under its influence, a low pressure area is very likely to form over Southeast Bay of Bengal during next 48 hours. It is likely to concentrate into a depression during subsequent 24 hours and likely to intensify further thereafter. It is likely to move nearly westwards and reach Tamil Nadu-Puducherry coasts around December 2.

Under the influence of the above system, light to moderate rainfall at most places with isolated heavy to very heavy rainfall on December 1 and heavy to very heavy rainfall at a few places with isolated extremely heavy falls on December 2 and 3 are likely over Tamil Nadu, Puducherry and Karaikal.

Meanwhile, the well marked low pressure area lies over south coastal Andhra Pradesh and adjoining west central Bay of Bengal. Under its influence, light to moderate rainfall at many places with heavy to very heavy falls at isolated places is likely over coastal Andhra Pradesh and isolated heavy rainfall over Rayalseema during next 24 hours.
