Sending ships to sea before a hurricane

Are ships ordered to leave port before a hurricane, or does each captain decide?

Navies try to sortie them early, although a storm's changing track can make the offshore route dangerous too.

Ships are normally sent to sea as quickly as possible before a severe storm reaches port. Open water gives a ship room to manoeuvre and avoids the concentrated hazards of piers, shallow water, and other vessels. The decision carries its own risk because a hurricane can turn and follow the group offshore. An episode of The West Wing, in which a storm reverses toward a carrier group, illustrates the real planning dilemma. Commanders choose the least dangerous forecast option while knowing that later movement can invalidate it.
