The city of Chennai usually does not see a lot of Monsoon rains and the monthly mean for June happens to be at 55 mm. However, this Monsoon season, Chennai has almost seen triple the amount of Monsoon rains so far at 158 mm.
Moreover, Chennai has recorded its 24 hour rains at 79 mm and 49 mm, respectively, which in itself is not a common phenomenon for the city during the month of June, as Chennai is a rain shadow area during the Southwest Monsoon period.
The city of Bengaluru has followed a similar pattern wherein so far the city has already recorded 198.9 mm of rains, which is almost double of the usual June rains for the city. Moreover, Bengaluru has observed the highest monthly rains of the decade surpassing 2016's 191.3 mm of rains.
Bengaluru also does not see heavy rains like this during the month of June and out of the four monsoon months, the lowest rains are seen in June itself.
For the forecast, both Chennai and Bengaluru will not see any significant activity and starting tomorrow, rains will see a further backseat. For the next 4-5 days, we do not expect anything significant taking place over both these capital cities.
