Waffle House Index (WHI) - an informal indicator of the severity of a storm, and its effects on a affected community. It is a measure of how prepared Waffle House is for disasters. They are known for either staying open during bad weather or reopening within a short time.
Waffle House is known for its ability to manage disasters well, particularly in areas where there are frequent hurricanes. It offers a limited menu that can be used in times of emergency and power outages. It also puts together "Waffle House Jump Teams" which can quickly reopen the restaurant following a disaster when it's safe.
