For Right now its best to donate to the Red Cross and Salvation Army
Salvation Army, Kevin Hart and JJ Watt also have set up something to raise funds (check their instagrams). I wouldn’t do red cross they didn’t really help Katrina victims or victims in Haiti from what I’m hearing
Operation USA is an excellent option.
Red Cross is the only one I track their efforts and therefore I trust them but Salvation Army would be my second choice.
