of two major events. It's set to be the busiest air travel day ever. At the same time there's a dangerous blizzard sweepling across the country this morning. The dangerous storm system heading for the east coast. After slamming the upper midwest. Snow threatening to cancel hundreds of flights. We have team coverage this morning. The forecast coming up. First let's go to Zachary kiesch who is as Laguardia airport. Zachary, good morning to you. Reporter: Dan, good morning to you. It's one of the busiest travel weekends ever. Some 40 million people under winter weather warnings. It could create a real mess out here. We're seeing more delays and cancellations than we saw yesterday as people begin that slow grind, that slow trek home. This morning a massive winter storm barreling across the country on what's expected to be the busiest air travel day in U.S. History. Tragedy in an extreme blizzard-plagued South Dakota. Nine people were killed in a plane crash including two children and the pilot. We had extreme wind, snow, visibility issues. Reporter: Heavy snow slams North Dakota too. Vehicles spinning on the highway, drivers barely able to see in white-out conditions as plows struggled to keep the roads clear. A similar scene in Minnesota. Weather crews out in full force with stranding cars littering the streets and interstates. Drivers proving to be no match for the snow storm as they wait for trucks to dig them out. Galeforce winds in Colorado violently whipping up snowfall making it impossible for people to push their cars off the road. On the west coast there's major flooding in California. Crews in San Diego using small yellow rafts to get people to safety. An urgent search in Arizona for a little girl. She and her family were swept away in a vehicle Friday night when it was overcome by flood waters. Two other children died. These storms wreak havoc in the west and March east, airports reporting hundreds of delays and cancellations. Today a record 3.1 million people expected to fly. The TSA trying to speed up the process using a new screening process for I.D.S at some airports nationwide. No long lines here at Laguardia airport in New York so far this morning. They're testing out the new technology in hopes of preventing long lines they've seen here in the past. The focus today will be on the east coast airports. You have to make sure to pack your patience. Whit? Zachary, thank you. The weather expecting to get worse. For a look at where the storm is hitting now and where it's headed next let's go to Cheryl Scott fromur Chicago station. She's in for rob this morning. Cheryl good morning. What are we looking at here? So many traveling home after Thanksgiving and there will be so many impacts. We're tracking this image storm. This area of low pressure still bringing heavy snow to the upper midwest and great Lakes. This low pressure will continue to slide to the east. We have rainy conditions and also snow expected across the northeast and new England. Here you can see the watches and warnings just littered across the northern half of the country. So many travel impacts will be felt. Let's track this system. As it continues to slide to the east, you can see places like New Jersey up into the city, this will be mainly rain with a wintry mix along and south of I-80. North of I-80 that's where the heaviest snow will be. We're talking places like Albany, western Massachusetts, New Hampshire, Maine, we'll see several inches of snow over the next 24 hours, upwards of a foot. Here in the city, a bit of a wintry mix with accumulating snow in Boston tomorrow.
