Just a quick compilation of how we can help. It is by no means a thorough list; drop me a message if there’s anything I’ve missed, and I shall add it here. If possible, please check if it’s verified; now is not the time to be spreading false information.
If you’ve got a place to stay/know of anyone in need of shelter:
There’s a crowdsourced spreadsheet available.
You can also volunteer here.
If you have trouble using the form/sheets, or if you are a government authority, police, or associated with rescue and relief in any way, please get in touch so we can help you co-ordinate on Twitter. Here are our Twitter handles: @weshnoo, @sowmyarao_, @shrinivassg, @tvabhinav and @hatamurali.
Stayzilla and BIG FM are collaborating efforts for this purpose as well. If you can assist, call at O44–46946000.
RJ Syed Mohsin is compiling screenshots of individuals offering assistance. If you come across a lead, send a screenshot here.
If you were on the roads recently:
FloodMaps is a crowdsourced effort to map inundated roads in Chennai. To help planners and city authorities understand the flooding problem, contribute to the map here.
And here is another one.
[On that note, Genie is offering to recharge for people in need. Just tweet them at @thehellogenie if you know anyone who is unable to reach out to people due to insufficient balance.]
If you can donate:

If you’re talking about this, please use the hashtag #ChennaiRains. The news channels are yet to pick the news up, and the hashtag trending will hopefully catch their attention.
Do not use the hashtag #ChennaiRainsHelp, unless you’re offering/in need of assistance.
