The heaviest rainfall in more than a century has wreaked havoc in Chennai, leaving thousands of people to be rescued because of high water levels. No supply of electricity, cellular network, lack of food, fuel and other essential items, have caused a lot of misery to people in and around Chennai. Thousands have been rendered homeless, as rescue workers, including the army and navy look to move the displaced people to shelter homes.
Here are some steps that you can take on your end to offer them help:
Offer shelter
This Google document, ‘#ChennaiRains gives information to locate a shelter, occupancy and corresponding contact information and social media links.

You can go and update the Google doc if you are willing to provide shelter.
You can also add your details to ‘klipher.com/savechennai‘ that lists all the information on availability of shelters in the city.
Buy them a Zomato meal
Zomato has offered a ‘Meal for Flood relief’ delivery service for people stranded in the city. The programme is supported by seven famous city restaurants including Adyar Ananda Bhavan, Prems Graama Bhojanam, Kolapasi, Dindigul Thalappakati, Nawab Sheikh Biryani, Meat and Eat and Katti Roll.
