An interactive map was published by the tourism website Smoky Mountains. It is set to help fall foliage enthusiasts make the most of the colorful season.

Alison Fox reported on it for Travel + Leisure. The map draws on various data. It includes precipitation and temperature forecasts, average daylight exposure, and soil moisture. It predicts the timing of leaves' color change across the continental United States.

Users can view weekly forecasts by selecting dates listed below the color-coded map. Click September 7, and swaths of green overtake the map, underscoring the widespread absence of fall foliage. By October 19, however, shades of orange, red and brown dominate. They reveal the arrival of patchy, partial, near peak or peak foliage in the northern and western U.S. Come November 30, all but the southernmost parts of the U.S. are past peak point.

"The predictive fall leaf map helps potential travelers, photographers and leaf peepers determine the precise future date that the leaves will peak in each area of the continental United States," said Wes Melton. He is one of the data scientists who created the tool. "We believe this ... will enable travelers to take more meaningful fall vacations, capture beautiful fall photos and enjoy the natural beauty of autumn."

David Angotti is another researcher responsible for the annual publication. He tells Patch's Beth Dalbey that no forecast is "100 percent accurate." He adds, Smoky Mountains' tool is one of the only proven to provide accurate predictions for the entire country.

Per Travel + Leisure's Fox, the team analyzed millions of data points collected by the National Oceanic and Atmospheric Administration. It also used other private and public organizations. Dalbey writes that the researchers refine their predictive algorithm every year. This is the sixth annual iteration of the map. It builds on sources such as historical and forecasted temperatures, leaf peak trends, and peak observation trends. These help produce the final product.

Plants stop producing chlorophyll, the chemical responsible for turning their leaves green, when fall approaches and the days get shorter. That's according to the U.S. Forest Service. This process unmasks pigments typically overpowered by chlorophyll. It creates the beautiful colors associated with fall foliage.

Last year there was a significant delay in fall colors' Midwest debut. It led the leaf-spotting Foliage Network to deem the season "bizarre." According to City Lab's Linda Poon, 2018 was the first time the group recorded almost no color change by the second half of October. When the leaves finally did change, green and brown appeared more often than vibrant orange and red.

Experts say fall foliage is running similarly behind schedule in 2019. Weather.com's Brian Donegan reported on the season. He said above-average September temperatures have delayed the timing of peak foliage by about a week.

Thanks to the warm weather, early October will likely mark the start of 2019's prime leaf-peeping season. New England and the Rockies experienced peak foliage last week. Tourists seeking autumnal reds and golds should pack their bags soon and prepare to enjoy the view.

    The features of telling where fall flows to and how and satellites for hurricanes discovery.

    More features to the map that could be helpful is a due date by the time we would reach a true falls that could tell us when we could prepare for us

    first time the group recorded almost no color change by the second half of October. When the leaves finally did change, green and red appeared more often than vibrant orange and brown and this is a cool article
