Chennai:30.09.2020

The city could achieve its average rainfall levels for the July-September period, as weathermen have forecast patterns of light rain with thunderstorms to continue in the city for the next 48 hours due to a cyclonic circulation or swirling winds over south Andhra Pradesh and its neighbourhood and the resulting convective activity. Chennai has a 5% deficit so far with 409.3mm rainfall registered against a normal 431.9mm with only a day left for the July to September season to end.

The regional meteorological centre, Chennai has forecast, “The sky condition is likely to be generally cloudy. Light rain with thunderstorms is likely to occur in some areas. Maximum and minimum temperatures are likely to be around 34°C and 27°C in the city for the next 48 hours.”

In its five-day forecast for the state, the nodal weather agency has forecast light to moderate rain is likely to occur at isolated places over north coastal Tamil Nadu, Chennai and its neighbours Chengelpet, Kanchipuram and Tiruvallur.

Officials said the rainfall is due to the cyclonic circulation over south Andhra Pradesh and neighbourhood between 4.5 and 5.8km above mean sea level, which has merged with another cyclonic circulation between 1.5km and 7.6km over westcentral Bay of Bengal of Andhra Pradesh coast. Cyclonic circulation, where winds swirl in the direction of the earth’s rotation, pulls moist air resulting in cloudiness that may bring rainfall.

Many localities like Kodungaiyur, Madhavaram, Perumbur and Vyasarpadi in the north, Avadi in the west and Velachery in the south registered sharp intense spells on Tuesday. This left 4.6mm in Nungambakkam and 10.1mm in Meenambakkam stations as on Tuesday 8.30pm.
