A total solar eclipse passed over North America on April 8, creating a path of totality that cast parts of Mexico, the United States and Canada in darkness.
About 31 million people live along the path of totality and witnessed the total eclipse, while the majority of Americans saw at least a partial eclipse.
The FAA is stopping some flights from taking off to two small commercial airports due to eclipse volume.
Certain flights headed to Southern Illinois Airport, located in Jackson County, and Veterans Airport of Southern Illinois, located in Williamson County -- both in the path of totality -- are being held at their destinations until at least 12 p.m. ET.
The FAA website indicates that the probability of the ground stop being extended is between 30% and 60%.

Why is April’s total solar eclipse historic?
The contiguous United States hasn’t seen a total solar eclipse since August 2017, but the seven-year difference between eclipses is "deceptive," Fred Espenak, a former astrophysicist from the NASA Goddard Space Flight Center and author of "Road Atlas for the Total Solar Eclipse of 2024," previously told ABC News.
"If you look previous to 2017, the last one was in 1979,” he said. "So, it's a little bit deceptive that these two eclipses were in seven years of each other."

The next total solar eclipse to occur in the contiguous U.S. won't be until August 2044 in Montana and North Dakota, and the next to span coast-to-coast is slated for 2045, according to NASA.
Comparatively, 2024's total solar eclipse is "better" than 2017's, because the path of totality is almost 60% wider and the duration of the eclipse is about 60% longer, according to Espenak, who explained some locations within the path will experience up to four and a half minutes of the eclipse.

This city in New York has been planning for the eclipse for 7 years
For seven years, Deb Ross has been helping prepare the city of Rochester, New York, to welcome thousands of visitors for the total solar eclipse.
Rochester, which is in the path of totality, is expecting between 300,000 and 500,000 visitors and to earn between $10 million and $12 million over eclipse weekend.
"I think probably I was little over the top, so maybe people were saying, 'Seven years out, really Deb? Six years out, five years out, this a little early, isn't it?'" Ross told ABC News. "But the fact is pulling all these folks together and working for something that's going to happen far in the future for three minutes and 38 seconds, that is a kind of wacky proposition. But it was really fun, and everybody just jumped right on board."

Rochester resident describes years of planning for eclipse

As chair of the Rochester Eclipse Task Force, Ross has recruited the local government, museums, small businesses and even the local transportation council to make the event memorable for visitors by creating eclipse-themed events, food and merchandise.
"We've had practice runs, we've had a lot of meetings to get at the nitty gritty, and I've been able to be part of those and watching everybody here play so beautifully together in this sandbox," she said. "I think what we'll be doing here on Monday, April 8. is converting hundreds of thousands of skeptics into eclipse chasers."

Weather forecast along path of totality
From Mexico to Maine, if you're in a city where the total solar eclipse will grace the skies Monday afternoon, cloud coverage may dampen your view.
Mazatlan, Mexico, will have low clouds through the morning. The clouds will begin to break by the afternoon, but the weather may still be mostly cloudy at the time of the total eclipse.
Del Rio, Texas, is forecast to have mostly cloudy skies, so eclipse viewing weather won't be ideal. There's a chance to see the eclipse in Dallas, where the skies will be partly cloudy with some passing clouds.
