A major disaster may cause disruption of services like stores and utilities over an extended time. It’s time to prepare for the first three weeks. Don’t worry, it’s not as overwhelming as it might sound.
In addition to the supplies you've put away for the first three days, continue adding enough water, food, and personal items to last three weeks. The simplest way to accomplish this preparation is over time. Each time you go shopping, purchase a little extra of the same food and personal items you normally buy. For water storage, consider some larger containers, like 5-, 15-, 30-, or even 55-gallon water storage barrels.
Alternate cooking methods and fuel sources are also important if your normal utilities are not available. Add additional propane, charcoal, or even solar-powered options to your disaster preparedness supplies.
Get prepared for the first three weeks!
