Heavy rain threatens to derail Thanksgiving travel in Northeast: Live updates

More than 55 million people are expected to travel at least 50 miles to reach their Thanksgiving destinations between Wednesday and Sunday, and more than 49 million of those travelers will be driving, according to the AAA.

The Transportation Safety Administration expects a significant portion of those drivers will be on the roads Wednesday. Thankfully, much of the inclement weather predicted for the week will be over, but drivers in parts of northern New York and northern New England should be prepared for possibly slick roads due to sleet and freezing rain Tuesday evening.

FAA Administrator Mike Whitaker took to X/Twitter to warn Thanksgiving travelers — who are likely to face possible delays, long lines, and congested airports — to be nice to the flight crews working over the holidays.

“If you’re flying, please be nice to your flight crew. They are there for your safety. The FAA has zero tolerance for unruly behavior,” he said in a post.

Air travelers on Tuesday are most likely to experience disruptions due to a winter storm system moving from the central US across the Midwest and into the northeast.

The National Weather Service reports that most of the precipitation falling east of the Mississippi River over the next two days will be rain.

A major storm system will move across the Midwest and into the northeast on Tuesday, bringing with it thunderstorms and rainfall, which may disrupt flights and cause less than ideal road conditions for motorists traveling for Thanksgiving.

There are some exceptions; the Central Appalachians into portions of the interior northeast may experience sleet and freezing rain on Tuesday morning, and accumulating snows are possible across northern New York state and into northern New England on Tuesday night.

Roads in parts of New York, Vermont and New Hampshire may be slick on Wednesday morning after overnights storms dump a mix of rain and possible snow on the region Tuesday evening.

Snow is expected to arrived in Maine on Wednesday as a storm system begins moving eastward across the US today.

The Midwest and northeast will feel the brunt of the inclement weather on Tuesday, with thunderstorms, snow, and rain likely.

The FAA estimates that 2.6m people will travel through airports each day during the Thanksgiving holiday week.

The administration said that long lines, delays, and congested airports should be expected all week long.

Delays and possible cancellations are likely as thunderstorms, heavy rain, and snow are expected to move from the center of the US through the Midwest and into the northeast on Tuesday and early Wednesday.

The Transportation Security Administration said the 2023 Thanksgiving travel season will be the busiest in US history.

The agency reports the busiest flight days will be Tuesday and Wednesday.

The busiest day for drivers will be Wednesday, according to INRIX, a transportation analytics company.

Drivers are advised to leave home early in the morning or after 6pm to avoid running into the heaviest traffic, INRIX told ABC News.

Inclement weather on Tuesday across the Midwest and northeast may cause delays for air travelers. The storms are expected to die down on Wednesday.

While the central and eastern US grapples with thunderstorms, rain, and snow, some Californians will have to contend with powerful Santa Ana winds ahead of Thanksgiving.

Wind advisories are in place for much of San Diego County through 2pm PST on Tuesday. Forecasters warn of “moderate to strong” Santa Ana winds, particularly on Monday.

Santa Ana winds are typically in excess of 40mph (64kmh) but strong gusts can exceed 100mph (161kmh). The stronger gusts can push cars, topple big rigs, and exacerbate wild fires during the arid fall months in Southern California.
