The Met department on Saturday said that the rains are likely to continue in the coastal parts of Tamil Nadu even though its intensity would be less, hinting that weakening of low pressure area in the region might bring some relief from relentless showers.
Regional Meteorological Director S R Ramanan said that Chennai is likely to remain cloudy.
"Yesterday's low pressure area over Sri Lanka and North Tamil Nadu coast has weakened into a trough of low pressure which is now lying over Sri Lanka and adjoining areas of Tamil Nadu coast. Because of this trough it has rained at many places of Tamil Nadu and Puducherry," Ramanan said.
"As far as forecast for next 24 hours is concerned, it is likely to rain at many places in Tamil Nadu and Puducherry, with some areas likely to experience heavy rainfall," he added.
Though water has begun to recede from many submerged areas, many more still remain flooded, necessitating the rescue teams to continue to work on a war footing.
