Every year, a tourism promotion website around Great Smoky Mountains National Park in North Carolina releases a fall foliage prediction map for the entire country. The map is fun to play with as it shows a week-by-week prediction for each state between Sept. 2 and Nov. 18. It also breaks it down on a county-by-county basis, displaying estimates for the degree of color change, from minimal or patchy to near-peak and peak. It’s “the ultimate visual planning guide to the annual progressive changing of the leaves,” the website says.
