Assembling a Supply Kit

A well-stocked supply kit is essential during a hurricane. It should include:

• Non-perishable food and water (enough for at least three days)
• A first-aid kit
• Flashlights and extra batteries
• A battery-powered or hand-crank radio
• Medications and personal hygiene items
• Important documents (copies of identification, insurance policies, etc.)

Staying Informed

Staying informed about potential storms is critical. Monitor weather forecasts and heed any warnings issued by local authorities. Sign up for local alerts and have multiple ways to receive updates, such as a weather radio, smartphone apps, and local news channels.
