It takes a lot for a Waffle House to close. If the "Waffle House Index" is flashing red ahead of an impending storm, you might want to think twice about staying put.

The "Waffle House Index" is an unofficial Federal Emergency Management Agency (FEMA) metric, where closed restaurꦍants suggest a need for serious disaster response.

Locations of the privately held Southern-based chain are normally open 24/7. In a 2015 episode of his CNN show "Parts Unknown," the late chef and travel documentarian Anthony Bourdain called Waffle House "a beacon of hope and salvation, inviting the hungry, the lost, the seriously hammered all across the South to come inside."

"If you get there and the Waffle House is closed?" then-FEMA Administrator Craig Fugate was quoted as saying in a 2011 Wall Street Journal article. "That's really bad. That's where you go to work."

But not even Disney (DIS) has a FEMA metric named after it.

"It never closes, it is always, always faithful, always there for you," Bourdain said of Waffle House. When it does close, you may want to get out of Dodge.
