Some places across the State, especially in south Tamil Nadu, may experience light to moderate rainfall till Sunday. Tirunelveli and Thoothukudi may experience heavy rain over the weekend.
A trough of low pressure over central parts of Bay of Bengal and adjoining equatorial Indian Ocean is likely to bring rainfall over a few parts of the State. N. Puviarasan, Director, Area Cyclone Warning Centre, said the weather system is expected to move towards the State’s coast. However, Chennai may not have any significant rainfall in the next few days.
On Thursday, Chennai recorded 30.3 degree Celsius, which is close to normal for the season. The temperature at night also dipped after Cyclone Phethai made landfall. A clear sky and increase in land breeze has led to the fall in temperature, officials said. As Cyclone Pethai too failed to bring rainfalls to over Chennai, the district continues to have a 54% rainfall deficit this season. It needs 41 cm of rain to touch its average for the northeast monsoon.
Officials said there is a chance for one more rain spell. But, it could only be confirmed after a few days.
