As of now, Tamil Nadu has received 6 percent less rains than its normal. However, the northern districts of the state particularly Chennai has been receiving on and off rainfall since last two days.
An upper air cyclonic circulation was over west central Bay of Bengal off Andhra coast and a trough was extending from North Coastal Andhra Pradesh till Tamil Nadu.
In the wake of this weather system, Chennai has managed to witness some showers. The Nungambakkam observatory in Chennai has received 32 mm rains in the last 24 hours from 08:30 am on Thursday.
Now, this cyclonic circulation which over west central Bay of Bengal off north Andhra Pradesh has become less marked. Additionally, Monsoon trough which was extending from North Coastal Andhra Pradesh till Tamil Nadu has also become insignificant.
Hence, light to very light rains with a few moderate spells in some parts of the city are likely to make an appearance for another 24 hours. Thereafter, there may be a gap of one or two days before the next spell of on and off light showers over the city.
These rains are expected to continue till September 22 though, intensity of rain will be light to very light in nature. However, cloudy weather may possibly give some relief from the scorching hot weather conditions prevailing over the state capital.
Moreover, Monsoon has started withdrawing from the western part of the country and the onset of Northeast Monsoon is also expected to commence from October 1. Significant increase in rainfall activity over the city is likely during the Northeast Monsoon only. Around 60% annual rainfall occurs during Northeast Monsoon in Chennai.
