Hurricane Irma could hit the United States by this weekend, meaning now is the time for coastal residents — along both the Atlantic Ocean and the Gulf of Mexico — to prepare.
The storm looked primed to match Hurricane Harvey's Category 4 level on Monday, per AccuWeather meteorologist Dave Samuhel, who said it's too far out to predict Irma's exact path.
Still, he issued a warning: "Have emergency supplies ready."
Here's what to pack in an emergency kit and additional steps to take ahead of a hurricane, according to the Federal Emergency Management Agency.
Emergency kits should combine basic staples (food, water) with supplies reflecting your family's unique needs, such medications or baby formula.
Water: First and foremost, store at least three gallons of water per person — enough to last each three days. If you think you'll be cut off longer, add an extra gallon per person per day.
Cash: Banks and ATMs could shut down. Power outages render debit and credit cards useless.
Documents: Keep copies of key documents in a waterproof, easy-to-carry container. These include identification such as passports and Social Security cards as well as insurance policies and bank account records.
Medications: Keep a one-week supply of prescription medications plus any over-the-counter items like pain relievers and antacids.
Food: Lay in a three-day supply of canned foods and dry mixes — nothing that needs refrigeration. Avoid thirst-inducing foods, and remember the dietary needs of those around you, including infants (ready-to-feed formula) and pets. Secure a hand-operated can opener.
Sanitation: Think moist towelettes, garbage bags and diapers. Consider paper goods such as plates and cups as well as plastic utensils.
Backup phone batteries: Extra batteries for your devices, also called portable power banks, could prove essential in a power outage. Here's how to prep your smartphone for disasters.
Additional tools: Flashlights with spare batteries, blankets, a first aid kid and NOAA weather radios are all recommended.
FEMA offers an extensive printable checklist for all-purpose emergency supply kits, too.
The agency also recommends tailoring supplies to whether you plan to evacuate or stay put at home, and to sign up for local alerts (just Google your city or country name plus "alerts").
