Huge Crowds Await A Total Solar Eclipse In North America. Clouds may spoil The View

It was projected to be the nicest weather in Vermont, Maine, New Brunswick, and Newfoundland after the eclipse.

It was expected to be North America's largest eclipse audience because to the highly populated path and more than four minutes of noon darkness in Texas and other locations. Most North Americans were guaranteed a partial eclipse, weather allowing.

Cloud cover is one of the trickier things to forecast,” National Weather Service meteorologist Alexa Maines said Sunday at Cleveland's Great Lakes Science Center. “At least, it won't snow.

Cliffhanging uncertainty added drama. Rain or weather, "it's just about sharing the experience with other people," said Chris Lomas from Gotham, England, who was staying at a sold-out trailer campground near Dallas, totality's largest city.

The moon would completely hide the sun on Monday's full eclipse. A twilight with only the sun's outer atmosphere or corona visible would be long enough for birds and other animals to fall silent and planets, stars, and possibly a comet to appear.

For 4 minutes, 28 seconds, the darkness is out of rhythm. This is roughly twice as lengthy as the U.S. coast-to-coast eclipse seven years ago since the moon is closer to Earth. The next total solar eclipse in the U.S. will be 21 years away.

From the Pacific to Mazatlan, Mexico, Monday's eclipse lasts five hours before traveling into Texas, Oklahoma, Arkansas, 12 additional Midwest, Middle Atlantic, and New England states, and ultimately Canada.

A moon shadow can travel almost 4,000 miles (6,500 kilometers) across the continent in 1 hour, 40 minutes. The sun must be viewed through eclipse glasses and filters, except when it disappears.

This time, the 115-mile (185-kilometer) route of totality includes Dallas, Indianapolis, Cleveland, Buffalo, New York, and Montreal. At least 44 million people reside within the track, and another 200 million within 200 miles.

Hotel and airplane reservations are sold out and roads are clogged due to eclipse chasers, amateur astronomers, scientists, and the curious.

Along the path, NASA and many universities have experts ready to launch research rockets and weather balloons and conduct tests. The seven astronauts aboard the International Space Station will also watch, 270 miles (435 kilometers) aloft.
