If you have family in Florida that was hit by the hurricane and you can't get in touch, contact the chapter of the Red Cross closest to your family's residence.
The Red Cross registers everyone that comes in for help, including food, shelter or medical assistance. They also are already beginning family re-unification programs putting family members in touch with each other.
The American Red Cross branches for the two major areas are:
Punta Gorda/Charlotte County Red Cross - (941) 629-4345
Orlando Red Cross - (407) 894-4141
You can imagine how busy the disaster services personnel are right now so the Red Cross asks that requests for family members only be done today. This is so families can be brought together first.
Friends in search of friends can call tomorrow onwards.
Hoping everyone is all right. Last I heard there were 3 confirmed deaths, which in view of the damage is incredibly low.
A complete listing of all branches in Florida can be found here:

Doantions for those affected can be made through any chapter of the Red Cross
Hope this is of some help.
