A fresh low pressure area over Bay of Bengal, the fourth in the span of 20 days, is expected to bring more heavy rains over Tamil Nadu from Saturday.
The forecast which confirms that the northeast monsoon is still intense over the region is a fresh blow to the state still limping towards normalcy.
"A trough of low at mean sea level lies over Southeast Bay and neighbourhood. Under this influence, isolated heavy rain would occur over coastal Tamil Nadu and Puducherry in the next 48 hours", a senior Regional Meteorological Centre official told Deccan Herald Friday.
The official said fishermen were warned not to venture into the sea as winds occasionally reaching up to 45 KMPH would blow in the north-easterly direction along and off Tamil Nadu and Puducherry coasts in the next 24 hours.
The state is just breathing easy as a fortnight of unprecedented rains claimed 190 lives and caused widespread damages. Rescue workers are returning home since rains ceased completely from Wednesday.
Meanwhile, the high-level inter-ministerial team from the Centre trusted with assessing the cost of heavy rains and floods in the state visited the worst-hit district of Cuddalore Friday morning.
The team, led by the Joint Secretary at the Home Ministry TVSN Prasad, also inspected various relief camps sheltering those affected by the cyclone in the district.
