Rahul expresses concern over incessant rains in Chennai

''The incessant rains in Chennai have become a cause for worry. Requesting our brothers and sisters in the state to follow all safety measures. And an appeal to Congress workers - please help in relief and rescue work. Take care, Chennai,'' he wrote on Twitter.

Most districts in northern Tamil Nadu, including Chennai, are likely to receive heavy to very heavy rainfall, an official said, even as the city and its suburbs received sharp showers all through the night and on Thursday morning as well.
