The U.S. government is using a popular slogan from HBO's "Game of Thrones" to prepare Americans for winter weather.
The Centers for Disease Control and Prevention has created an e-card with the slogan encouraging concerned Americans to share tips with their friends on how to deal with snow.
"Share our 'Game Of Thrones' eCards to help protect the realm from winter weather," noted the CDC on its emergency Twitter account.
The card features the popular slogan "Winter is coming" from the HBO show.
The card advises recipients to store food, water, blankets and snow shovels in advance of winter weather and to make a "Family Communications Plan."
The card also reminds drivers to minimize travel, stay on main roads and keep their gas tanks full.
