I would highly suggest that if evacuations are ordered for your area, regardless of your fiancée's profession, that you bug out. For one, its one less thing for him to have to worry about; less stress on him if your at home and crap goes sideways. Especially if at some point you are planning a family. Don't risk yourself or your family just because your husband has a job to do. Get away, get to safety, be one less thing to distract him from doing his job and being safe.
My sister's family had to bug out from Miami during Irma. She had to stay as she's a medical equipment repair manager. She stayed at the hospital, where it was safe, instead of at home.... which was lucky because one of their trees almost hit the house.
