Texas floods

Mariah • Baby #4 :)
So I'm totally freaking out. There is a flood watch this weekend for Texas and I am due this weekend. I don't live in an area that floods but my hospital is 30 min away! That's totally not safe. What do I do if I go into labor during a storm? Call an ambulance?? Won't that be insanely expensive?? I'm totally freaking out. I need a plan... Any ideas?
