You are within the cone. You should be leaving if you live in a structure that is susceptible to high winds. Even if the storm center passes well east you will undoubtedly have hurricane force winds. If you have trees around you those will probably fall onto your house. I cannot comment on water issues, not knowing your elevations but can certainly say with some certainty to expect flooding and rain penetration through windows, eaves, doors, etc. Wind borne debris is a major, major problem.

My advise. Go! It is not worth your or your family's lives. God bless.
