If you've ever traveled on a road trip across the eastern U.S. you’ve likely seen or stopped by a waffle house restaurant. The major restaurant chain has activated a storm center to keep an eye on Hurricane Florence.

The legendary breakfast chain is well-known for keeping doors open during natural disasters. FEMA came up with the phrase "waffle house index" it's a way to measure how badly storms affect an area. If a waffle house closes, officials believe that area must have been hit hard.

Waffle house is headquartered in Georgia and has more than 2,000 locations, mostly in the south.
