One source of possible flooding, although it could be minor, would be from your air conditioner that sat silent all winter. Be sure to have it thoroughly inspected by a professional to ensure it is operating properly and all hoses and connections are in good shape.
Remember, even a small amount of water intrusion can cause all kinds of problems, even mold and the issues related to that.
When water does come in uninvited, do the right thing and quickly call a dedicated, professional water damage pro in your area.
