What the agency told people to do
Stay calm and keep informed. Comply with any evacuation orders that are issued for your area. If you live in a metal roof or container home, or you live in a surge zone or any location prone to flooding, evacuate to a designated shelter or ride out the storm in the sturdy home of family or friends outside of evacuation zones. Items to bring to a shelter include a first aid kit, medicines and prescriptions, baby food and diapers, games and books, toiletries, a battery powered radio, a cell phone, flashlights with extra batteries, a blanket or sleeping bag for each person, personal identification, copies of key papers such as insurance policies, available cash and credit cards. Remember, pets are not allowed in most public shelters, so check ahead with your intended shelter. Regarding your home or business, cover all windows and doors with shutters or plywood. Move patio furniture and other loose objects indoors. Brace all exterior doors, including garage doors. Do this as early as possible. If you need to make a trip to the hardware store, the grocery store, or the gas station, do so as early as possible.
