Sayonara South West Monsoon 2019

Yes, it’s time to bid good bye to the famed Indian Summer monsoon (Technically it got over on September 30) and welcome the retreating winds from the North East in due course of time.

The mega monsoon blockbuster movie got off to a sluggish start, the key players (synoptic factors, the monsoon lows, off shore trough etc) enacting the role quickly understood the screenplay and the responsibilities bestowed upon them. The core team got into the monsoon mood in a jiffy knowing the expectations and the pressure they were in. This monsoon box office were roaring across the country by early August and the resultant precipitation accumulation were just on the threshold of breaking many records set earlier. The pace of the monsoon movie was such exhilarating, the screenplay had to be tweaked without the usual Intermission ( Break monsoon) seen regularly.

The stunning performance of the monsoon were heard loud and clear even in places like Coimbatore city, where the gate collection of precipitation exceeded everyone’s expectations in the second week of August. Was sort of a silent movie with high definition digital dolby Atmos sound. The Sound of Monsoon music aided by great soul searching lyrics ensured a perfect combo to entertain one and all.

The historical movie were never short of the usual drama or suspense as few pockets of the country which were left high and dry (Telengana, Bihar etc.) with a subdued performance rose majestically to a standing ovation from from the audience.

Overall, 2019 ( Sound of Monsoon Music) will be remembered for years to come for its amazing screenplay, flawless editing, action, drama, suspense and the musical melody it provided.

It’s time for the SWM silver screen to roll down and to pave way for the reversal of winds.

Here’s a quick look into the overall performance of the monsoon movie .
