This sounds like a perfect example of why there is a cause of action in FL for temporary custody by extended family. It can be fast and easy if the parents will consent to this, but long and drawn out if they will not. Speak with them about having your sister come and live with you for a while until they can get onto their feet, and then go to see a family attorney about this.
