Hurricane Irma in the Tampa area?

My step-son and my fiances ex wife live in New Port Richey, from what I understand thats near Tampa. I am super worried and haven't been able to turn off the news since last night but the ex doesn't seem too worried about it. Shes staying in a concrete home with a generator and plenty of supplies but I really want to insist that they come out to stay with us until its over. (We live in AZ). Am I overreacting? I have no experience with this kind of weather. I have only ever lived on AZ.
