The index is based on Waffle House's reputation for having good disaster preparedness and staying open during extreme weather or reopening quickly afterwards.
The index consists of three levels, based on the extent of operations and service at the restaurant following a storm:
The measure is based on Waffle House's reputation for staying open during extreme weather and for reopening quickly, albeit sometimes with a limited menu, after very severe weather events such as tornadoes or hurricanes. The chain's disaster preparedness measures include assembling and training "Waffle House jump teams" to facilitate fast reopening after disasters. Waffle House, along with other chains (such as Home Depot, Walmart, and Lowe's) which do a significant proportion of their business in the southern US where there is a frequent risk of hurricanes, have good risk management and disaster preparedness. Because of this, and the fact that a cut-down menu is prepared for times when there is no power or limited supplies, the Waffle House Index rarely reaches the red (closed) level.
The "Waffle House Index" sits alongside more formal measures of wind, rainfall, and other weather information, such as the Saffir–Simpson Hurricane Scale, which are used to indicate the intensity of a storm.
A Waffle House location may close in preparation for an incoming storm for the safety of its customers and employees, which is unrelated to actual storm damage. The intent of the Waffle House Index is to measure how quickly a location reopens after the storm passes. The quicker the reopening, the less overall damage the area sustained in the storm.
