Millions are hoping for clear skies as anticipation grows ahead of Monday’s total solar eclipse.
Forecasters are predicting cloudy conditions in northern Mexico, Texas and parts of the Great Lakes region.
Better weather is expected in western Mexico and parts of the US Midwest, with clear spring skies likely in New England and Canada.
The total solar eclipse, the first to cross the continent since 2017, will first hit land on Mexico’s west coast.
It will track north-east across heavily populated areas and several major cities in three countries.
Some areas along the path of totality – where the moon totally obscures the sun – will experience darkness for nearly four-and-a-half minutes.
According to NASA, 31.6 million people live along the path of totality, and millions more are expected to travel to catch a glimpse of the celestial event.
NASA and its partner organisations are hosting more than 100 events, including a gathering where the eclipse will first be visible from land in Mazatlan, Mexico and festivals at the Cotton Bowl stadium in Dallas and at Indianapolis Motor Speedway in Indiana.
Crowds will fill a football stadium in Carbondale, Illinois, where the path of Monday’s eclipse will intersect the path of the last solar eclipse to travel across the United States, in 2017.
More than 300 couples plan to get married under eclipse skies in a mass wedding in Russellville, Arkansas.
