As the temperature drops and autumn sets in, Mother Nature is painting the treetops in vibrant hues of red, orange and gold, and many people are planning their leaf-viewing vacations.

随着气温的下降和秋天的来临，大自然母亲把树梢涂成鲜艳的红色、橙色和金色，许多人都在计划赏叶度假。

SmokyMountains.com created a prediction map for the year's fall colors using millions of historical data points from the National Oceanic and Atmospheric Administration (NOAA).

SmokyMountains.com网站利用美国国家海洋和大气管理局(NOAA)的数百万个历史数据点，为今年的秋季色彩绘制了一张预测地图。

"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," Wes Melton, a data scientist and CTO of SmokyMountains.com, told Travel + Leisure.

SmokyMountains.com网站的数据科学家兼首席技术官韦斯·梅尔顿(Wes Melton)在接受《旅游+休闲》(Travel + Leisure)采访时表示:“这种预测秋叶图可以帮助潜在的旅行者、摄影师和赏叶者确定未来树叶在美国大陆每个地区达到顶峰的准确日期。”

"We believe this interactive tool will enable travelers to take more meaningful fall vacations, capture beautiful fall photos and enjoy the natural beauty of autumn," said Melton.

梅尔顿说:“我们相信，这个互动工具能让游客们度过更有意义的秋季假期，捕捉美丽的秋季照片，享受秋天的自然美景。”

The color change of the leaves depends more on light than temperature, so it takes place at about the same time each year. But temperature, rain and other weather conditions can have an impact on the timing of the leaves' changing color. Thanks to warmer-than-average temperatures, fall is taking longer to come around for 2019. The good news is, with much of the U.S. having had an unusually wet summer, the tree are healthy and happy.

树叶的颜色变化更多地依赖于光而不是温度，所以每年大约在同一时间发生。但是温度、降雨和其他天气条件会影响树叶变色的时间。由于气温高于平均水平，2019年秋季的到来需要更长的时间。好消息是，由于美国大部分地区经历了一个异常潮湿的夏天，这棵树健康而快乐。

Here's a look at what to expect this fall if you're looking for colorful foliage.

如果你正在寻找五彩缤纷的树叶，下面就让我们一起来看看这个秋天会发生什么吧。

Northeast

东北部

Peak time: There are a few patchy areas in the Northeast where leaves have already started to change, per SmokyMountains.com's map. The region may be at or near its peak by early October, and it'll be past its peak by late in the month. Fall foliage tends to peak for about one week around October 5th in Vermont, whereas the northern parts of New York and Vermont will be past their peak by mid-October.

高峰时间:据SmokyMountains.com网站的地图显示，美国东北部有几个零星地区的树叶已经开始发生变化。该地区可能在10月初达到或接近峰值，并将在本月末超过峰值。在佛蒙特州，秋天的树叶通常在10月5日左右达到一个星期的高峰，而纽约和佛蒙特州的北部地区将在10月中旬达到高峰。

Southeast

东南部

Peak time: Some parts of the Southeast will have minimal to patchy color changes by the middle of October. The leaves are changing in North Carolina around November 2nd, but for peak foliage, aim to head outside around November 9th. If you give it a few more weeks, swatches of Virginia and Tennessee will be at their peaks. However, most of the region won't start to peak until early November, with the southernmost areas not peaking until the middle of the month.

高峰时间:到10月中旬，东南部部分地区的颜色变化将是最小的，甚至是零星的。北卡罗莱纳的树叶在11月2日左右会发生变化，但如果是树叶的高峰期，最好在11月9日左右出门。如果你再给它几周的时间，维吉尼亚州和田纳西州的部分地区将会达到顶峰。不过，该地区的大部分地区要到11月初才会开始见顶，最南端的地区要到本月中旬才会见顶。

Midwest

中西部

Peak time: The northern portions of Michigan, Wisconsin and Minnesota — will peak by early October. The rest of the region is expected to peak later in October.

高峰时间:密西根州、威斯康辛州和明尼苏达州的北部地区将在10月初达到高峰。该地区其他地区预计将在10月晚些时候达到峰值。

Central U.S.

美国中部

Peak time: The northernmost states in the region won't begin to really change up the colors until near the middle of October. Texas' leaves will change from November 16th through the end of November. In the northern part of the Lone Star State, you might see them at peak as early as November 9th.

高峰时间:该地区最北部的州要到10月中旬才会真正开始改变颜色。从11月16日到11月底，德州的假期将会改变。在孤星州的北部，你可能在11月9日就能看到它们的高峰。

Northwest

西北部

Peak time: The leaves will start to visibly change in Washington state around October 1st, and peak around October 12th. You may be able to see peak foliage as late as October 26th in southern parts of the region.

高峰时间:华盛顿州的树叶将在10月1日左右开始明显变化，10月12日左右达到高峰。在该地区的南部，你可能会在10月26日晚些时候看到树叶的高峰。

West and Southwest

西部和西南地区

Peak time: Northern California will see the peak of the season from about October 26th through November 9th. If you're down south, plan to head out November 9th through mid-November. Some parts of the Mountain West are already receiving their first snow of the season, which will dampen fall foliage.

高峰时间:北加州将在10月26日到11月9日之间迎来这个季节的高峰。如果你在南方，计划11月9日到11月中旬出门。西部山区的一些地区已经迎来了这个季节的第一场雪，这将抑制秋天的树叶。
