The situation isn’t looking up in the immediate future. The India Meteorological Department has now forecasted ”heavy to very heavy” rains in the city over the next four days. Officials at the Regional Meteorological Centre have warned the Press Trust of India that low pressure over nearby southwest Bay could also cause “isolated extremely heavy rainfall” for Chennai, Kancheepuram and Tiruvallur.

On Dec. 1, the army was deployed in two areas of Chennai to start rescue operations. Two columns of the Garrison Infantry Battalion are at work at Tambaram and Oorapakkam areas of Chennai, following Tamil Nadu government’s request for military assistance. The navy is also on stand-by, according to The Times of India.

In a tweet, prime minister Narendra Modi “assured all possible support and cooperation” for the soaked state.

Ola, a local ride-sharing service and Uber rival, has started a free boat service to ferry people from waterlogged areas of Chennai, as Quartz had earlier reported. Another Indian technology startup, Stayzilla—an online aggregator of budget and home stays—has launched a campaign to facilitate listings of those who wish to open their homes to people displaced by the rain.
