As crews are doing everything they can to help people in Houston, people across the country are also pitching in.
This includes five-year-old Jett, a Houston native who now lives in Philadelphia. Jett wanted to help his home city and his family, so he started a lemonade and sweet tea stand.
It only cost 50 cents a cup, and all the money goes to those affected by Harvey.
"Jett was a little concerned over the last few days," said his mother. "We were just thinking of things we could do to help and we feel so far away."
Wearing a superman cape and a Houston Texans hat, Jett says he's happy people want to help.
