For a big storm, leave the area and get a motel room. All you do at this point is wait and see. It's no doubt, Ms. Holmes has the best idea - check into a motel miles away. Consult your local authorities for information regarding storm surge, a dome of sea water that rolls inland due to the force of strong winds. Such a surge can raise the water level as much as 30 or more feet in many places.
Hurricanes are serious business.
Pay attention to weather reports and get out as soon as possible.
