On Monday, when Chennai received heavy rainfall, the story was no different as several areas were mildly flooded causing massive traffic jams in busy thoroughfares of the city. Along with Chennai, Tamil Nadu's coastal areas too received rainfall. The IMD predicted heavy to very heavy rainfall in Chennai and at least eight other coastal districts in Tamil Nadu over the next 24 hours, which means Tuesday is also going to be a wet day for the southern state. Now, as heartbeats of several faint-hearted and the curious ones have increased, worrying trouble due to rains, it's social media, especially the micro-blogging site, Twitter, that is constantly providing weather updates and at the same time dispelling rumours to avoid panic among the residents of Chennai. Chennai, as we have seen during the 2015 floods, has a strong presence of social media warriors who came to the rescue of thousands of people. Thus since Monday, the hashtag--#ChennaiRains--remained one of the top trends.
