(WTEN) — In the coming weeks, millions of leaves will begin changing colors across the country.

The website SmokyMountains.com created an interactive map predicting when counties across the country will see peak fall colors.

Slide the bar at the bottom of the map to see the progress of peak foliage across America.


According to the North America Oceanic and Atmospheric Administration, the color change all starts inside the leaf.

In the summer, leaves are green because they’re making lots of chlorophyll, which helps plants make energy from sunlight. There are four main pigments in each leaf:

Chlorophyll (greens)
Xanthophylls (yellows)
Carotenoids (oranges)
Anthocyanins (reds)

As the days shorten, the leaves begin to change because the leaves are producing less chlorophyll to prepare for winter. Once this happens, NOAA says the green colors begin to fade and the reds, oranges, and yellows become more visible.

NOAA says changes in local weather conditions can play a role in when leaves will change in your area. A drought or early frost can cause leaves to fall without having the chance to change colors.
