Evacuating Florida's East Coast.

We live in Brevard county FL right where Hurricane Matthew is set to hit as a Cat 4. They are predicting 130mph gusts and almost 100mph sustained winds. I'll be 38 weeks on Friday and they announced that emergency vehicles cannot come for you if it's over 50mph and I'm not looking for an unassisted home birth during 10mph winds. We also have a 5 and 3 year old. So long story short we are evacuating inland around 4am (hoping to avoid bad traffic). Prayers appreciated. I'm terrified of leaving everything we own behind not knowing if any of it will be here when we get back.
