The Mocidade Independente samba school, one of Rio’s most popular, has 240 drummers in its section.

Nor’easters are usually winter weather events, and it is unusual to see them in May. They typically form when there are large temperature differences from west to east during winter when there is cold air over land and the oceans are relatively warm.But right now there is a traffic jam in the atmosphere because of an area of high pressure in the Canadian Arctic that is allowing unusually cold air to funnel down over the Northeast. The low pressure system off the East Coast is being fueled by a jet stream that is unusually south at the moment.

“It really is a kind of a winter-type setup that you rarely see this late,” said Judah Cohen, seasonal forecast director at the private firm Atmospheric and Environmental Research.If this type of pattern in the atmosphere happened two months earlier, he said, “we’d be talking about a crippling snowstorm in the Northeastern U.S., not just a wet start to Memorial Day weekend.”O’Malley reported from Philadelphia.

WASHINGTON (AP) — President Donald Trump on Saturday ripped into Walmart, saying on social media that the retail giant should eat the additional costs created by his tariffs.Although the U.S. is a major producer of certain types of semiconductor chips, the nation’s share of global chip production — measured by volume and not dollar value — fell from 37% in 1990 to just 10% in 2022, according to the Semiconductor Industry Association. As a result, the country relies heavily on imports from Taiwan and South Korea for advanced chips.

Major manufacturers like Taiwan Semiconductor Manufacturing Corp. are investing to build up U.S. facilities, partly due to incentives put in place during former President Joe Biden’s time in office. The CHIPS Act,, was designed to revive U.S. semiconductor manufacturing while sharpening the U.S. edge in military technology and minimizing future supply chain disruptions.

Because of the CHIPS Act, the U.S. is projected to more than triple its semiconductor manufacturing capacity — the highest rate of growth in the world during that period, according to a May 2024 report from the Semiconductor Industry Association and the Boston Consulting Group.Barry Broome, president of the Greater Sacramento Economic Council, said weaknesses in the semiconductor supply chain became evident during the pandemic, when the U.S. experienced
