Rains over Tamil Nadu and Puducherry are expected to recede gradually in the next three days, during which the city and its suburbs would only receive light showers, said a forecast from the meteorological department.

“The low-pressure area over interior Tamil Nadu and its neighbourhood now lies as a trough of low. A trough in easterlies runs from Kanniyakumari area to interior Tamil Nadu at 5.8 kilometers above the mean sea level,” said S Balachandran, the deputy director general of Regional Meteorological Centre, Chennai.
Since the onset of monsoon, Tamil Nadu received 28 cm rainfall against the normal of 33 cm, registering a deficit of 13 per cent. The season has been poor for Chennai, too, which recorded a rainfall of 32 cm against the normal 57 cm – a 45 per cent deficit.

The highest rainfall in the last 24 hours (as of Friday) was recorded at Chengalpattu, which received 18 cm, followed by Madurantagam at 14 cm. Mahabalipuram (10 cm); Uthiramerur and Vandavasi (9 cm); and Marakkanam, Gingee, Tindivanam and Vanur (Villupuram), Parangipettai (Cuddalore), (8 cm), too witnessed significant showers.
At the two stations in Chennai, the rainfall was 12.3 mm (Nungambakkam) and 16.9 mm (Meenambakkam) in the same period. The forecast has it that the city would record minimum and maximum temperatures of around 25 degrees Celsius and 32 degrees Celsiusrespectively.
