Who is putting hurdles in India-South Africa 2nd T20I?

The second T20 match between India and South Africa is to be played today. India will try to seal the series for the first time by winning this match. But, the big problem is that rain is going to become a hindrance in this. Actually, the weather in Guwahati is bad and there is a possibility that its effect can be seen during the match as well. Now if this happens, then the match can be dusty, and in that case Team India may have to wait for Indore to win the series.
