How much emergency water and food should a Hawaiʻi household keep?

Two weeks' worth. Because Hawaiʻi relies on shipping for most of its food and supplies, people here need two weeks of emergency supplies in case a disaster like a hurricane or tsunami damages ports and supply chains, the Hawaiʻi Emergency Management Agency says.

The agency recommends one gallon of water per person per day, for drinking, cooking and personal hygiene: 14 gallons per person for two weeks. Water stored in reusable containers should be changed every six months.

The main elements of emergency supplies, it says, are water, food, medicine, power and information; it suggests low-cost foods with lots of protein and calories, and adding a little to the pantry each week.
