Millions under winter weather alerts on busy post-holiday travel day

By Michelle Watson, CNN

(CNN) — More than 30 million people are under winter weather alerts across the Midwest and Northeast early this week with another storm threatening to upend travelers’ plans on what is expected to be one of the busiest travel days this holiday season.

At least 2 million people are under blizzard warnings in the Midwest, where winds could gust from 40 to 60 mph. Those wind gusts could blow heavy snow around, reducing visibility to less than a quarter of a mile in many warning areas.

More than 3,000 flights within, into or out of the US are delayed Sunday, with about 400 cancellations, according to FlightAware.

New England will see rain and freezing rain late Sunday into Monday, but the Ohio Valley and I-95 corridor will see mostly rain. And in the central and southern US, temperatures will go from 20 to 30 degrees above average this weekend to 10 to 15 degrees below average on Monday and Tuesday.

The worst conditions will be Sunday afternoon through the overnight hours across the Midwest. The National Weather Service office in Des Moines, Iowa, “discouraged” those traveling Sunday into Monday.

“Dangerous travel is expected for much of the next 24 hours! Blowing snow will lead to whiteout conditions over northern Iowa Sunday and Sunday night,” the Weather Service said in a post on X. “Travel in this area is discouraged!”

More than 109 million people are expected to travel via car for end of the year trips, according to AAA – an increase of 2% compared to last year, according to the organization.

Sunday’s weather is just the latest in what’s already been a tough travel weekend for those in the northeast.

Portions of the northeast will see a mix of rain and freezing rain Sunday which could lead to ice accumulations of up to a tenth of an inch – in places that have already received snow.

Just over four inches of snow fell in New York City’s Central Park Saturday, the city’s most snow since January 2022, about half of the amount the National Weather Service predicted ahead of the storm.

Waiting at LaGuardia Airport Saturday, Felicia Reich said her flight to Fort Lauderdale, Florida, was delayed by one hour.

“I was expecting it, but I was prepared,” she said, bundled up in a heavy coat and orange and yellow knit hat.

At one point on Saturday, more than 30,000 homes and businesses were without power in Michigan, according to poweroutage.us.
