How do I know if my house is in a flood zone?

I am currently looking to buy a new home in Florida and I am very concerned about the house being in a flood zone. Where can I find reliable information on Florida flood zones and more importantly search flood zones by address so I can see if the particular houses I am interested in are in a flood zone or not. Thanks in advance!
