Hospital for Hurricane Irma ?

I’m currently 38 weeks pregnant and I live in Central Fl. When the storm is expected to hit on Saturday I will be pretty close to 39 weeks. I don’t think Central Fl will get hit as badly as my family in S Fl but they are urging me to “check into” the hospital before the storm hits. Can you do that? To me it doesn’t sound right. “Check in” sounds like what you do at a hotel, not a hospital. If there is nothing wrong with me how could I be able to stay at the hospital? Can someone explain this to me?
