As travelers prepare to hit the road or the skies for the Thanksgiving holiday, two major storms are already impacting flights and roadways. Storm alerts have been issued from the West Coast to New York, covering 26 states in total.

Over 100 million Americans are currently under alert for these two storms.

The airports most impacted by the storm systems thus far are Denver International Airport, Phoenix Sky Harbor International Airport and Los Angeles International Airport.

As a result of the storm systems gaining strength, top airlines in the U.S. such as American, Delta, Southwest and United have expanded their travel advisories for the coming days and are waiving change fees for impacted travelers.

Airlines have started issuing advisories and waiving change fees ahead of a series of storms heading across the United States during the Thanksgiving holiday travel period.

As for Tuesday, a low-pressure system will move over the Midwest, while a second system is likely to push ashore into the West Coast starting Tuesday into Wednesday. Travel delays are possible for the Midwest into the lower Mississippi Valley, as well as parts of the Rockies and the Pacific Northwest.

Many travelers will be taking to the road and skies on the Wednesday before Thanksgiving, but the weather could impact plans. Scattered rain showers will soak the East, while windy conditions in the Great Lakes and Northeast could cause delays at local airports. Snow is also expected to cover roadways from the Sierra Nevada to the interior West.

While Thanksgiving Day won’t feature as many travelers hitting the road, those who do plan to travel should be expecting delays, as rain and snow could cause problems from California into the Rockies and Plains. In addition, lingering wind has officials concerned airport delays could be common in the Northeast Thursday.

In total, more than 55 million travelers are expected to travel 50 miles or more from their homes for the holiday. This makes it the second-highest Thanksgiving travel volume since AAA began tracking in 2000, behind only the record set in 2005.
