As Hurricane Irene approached the U.S., people in the storm's path were frequently advised to "batten down the hatches."
Today, that phrase means "prepare" - often for a literal storm (e.g. Irene) or a figurative one (e.g. someone's tempestuous mood).
A batten is a strip of wood used to connect or reinforce something, or to secure it tightly. The phrase "batten down the hatches" originally meant to prepare a ship for stormy weather by closing and covering openings.
