Vardah Cyclone

Vardah Exclusive Details-

Hrishi's experience-

"I feel really sad for his absence for the past 2 days. Just now he says power restored. Really a fury in South Chennai areas.."Actually i love Cyclones and extremely Heavy Rainfall...But this is Worst than 1st December Downpour...My area Palavakkam was kept under a rain Carnage from 1pm to 3pm and my AWS recorded a massive Total of 284mm in just 3 hours spell. Even near my College its flooding. By evening, the situation beacme Worsen and really i was totally upset. Power gone and my mobile Charge drained. Don't know what to do, full area under dark. Even the Mobile net connection was lost. I never imagined such a damage that too to Chennai", he added.

Sai Krishna's Experience-

Me too a team mate of WOS. All started with a drizzle in Morning at Chepauk. Suddenly there was a heavy rain towards afternoon. Gusts slowly grabbed speed around 11.45 am and peaked near 1 pm. Cant able to see the other side of Building indeed. The winds were Gusting around 125 km/h in my area and it was a dream run of winds. I cant say in my words, such a deluge making up to 197mm in just 2 hours. Since we are near to Sea, we had a direct pose of winds and its like a terrifying gust. The howling sound is something which is scary. Thanks to the government At last they declared holiday for 3 days. I was about tell you all, Never under estimate the power of Cyclone". 

Sanjana Kumar Experience-

"Actually i was unaware of this Cyclone. Started my day as a Normal day. Never Experience a Cyclone Till date in My life. I am from Irunjalakuda, Kerala. Now Working in Hyundai company and a good friend of Sai, the admin. That day started as a normal day, the clock was ticking 11.00am, i was typing computer and furnishing some details. Suddenly my colleagues told me the news on Cyclone. I opened the Windyty app and saw the wind. It was actually a big monster i saw for the first time in Map. Around 1.00pm, i texted Sai but he didn't respond my message. I said him, "Sai sir came" and went to work. Sudeenly around 3.30pm, a big gust rolled through. I was shocked to see such a big gust. Super winds and a Cat 2 feel. Infact my heart was beating like anything. First time in my life. That hauling sound, unforgettable. Infact Tropical cyclone is unimaginable and unpredictable, mainly in our countryside. It was 7 pm, i came out of office. No power around the place. Really i was a bit feared. No internet connection and No contact with parents. Really horrible. Don't know how to manage things. Finally it was 3 days aftermath, i got network and power access back. First time in my life, facing a difficulty itself an experience".

Coming to the Actual Winds and Quantum-

As per the Radar, if we see north chennai got more Winds whereas the Parts of south chennai got Winds and Rains. Heavy rains seen close to Tambaram, Kelambakkam.

How much loss estimated till now?

News channels telling a loss nearing 6749 crores to Tamilnadu and about 586 crores to Andhra Pradesh. There were several Videos of Lifting cars, Bus, even a big Building published by Hindu news-facebook (Have a look). The more loss is incurred along Northern Suburbs. One reason i want to Mention is the Unplanned constructions here and there in the city, without proper attestation of authorities concerned. Our city is planned to handle a rainfall up to 15cms and not a 49cms deluge (1st december, 2015-Tambaram) and its made to handle a wind speed around 50 kmph but not a 120 kmph storm. The additional unwanted and unplanned constructions add up into loss. The Society need to see the future losses, instead of building beautiful and extra-ordinary constructions. What for building a 100 storied building and getting washed by a storm??..Haha tell me..its waste...'ok' if its 120 kmph cyclone. What will happen if some Cat-5 cyclone with 250 kmph strucks ???....who will pay the loss?? Can the insurance give?

Structural engineers need to investigate about the Material stability to with stand high tension winds and Gusts. There must be a compensation to the coast which we pay. Need to improve this area to reduce losses.
"Its in our hands to lay future for our futuristic country...Lots of young blood in India. Come out and re build the unplanned"

Lines of Civil Engineer-

Pon Karthikeyan (Civil student, in my college)-
"Reinforcement of Cement structures needs a proper ratio of Sand, Water, Cement and Lim...they should be mixed in a proper ratio as per the Civil guidelines. But some illegal workers, reduce the amount of ratio and build flyovers and bridges...if cyclone comes, can it handle?"
"Aim- To improve strength of the material...(Futuristic goal)" He adds.
