A powerful storm making its way east from California across the U.S. is causing travel chaos for millions of people returning home after Thanksgiving, with forecasters warning of intensifying snow and freezing temperatures in the Midwest.

High winds and ice are expected to make travel almost impossible in some places.

A 5-year-old boy’s body was found Saturday, but two young children remained missing after a truck they were in was swept away while attempting to cross a runoff-swollen creek in the Tonto National Forest in Arizona.
Gila County sheriff’s Lt. Virgil Dodd said the boy’s body was found about 3 miles downstream and that the search continued for the other two missing children.
The Gila County Sheriff’s Office said emergency personnel and law enforcement helicopters on Friday rescued two adults and two children who also were in the military-style truck swept downstream in Tonto Creek near the small community of Tonto Basin.
Sheriff’s officials previously said a total of six people, including four children, were rescued Friday at locations along the creek.
Adverse conditions included heavy brush and slippery mud along the creek and frigid water from snowmelt, but officials said they remained hopeful.
‘That’s why we’re trying to do our very best out there today in hopes that we can get the children to safety,” said sheriff’s Lt. Virgil Dodd. ‘It’s really important that we find these kids and get them to safety.’
‘We have no information as to why they were trying to cross the creek,’ Dodd added. ‘We think everybody was in the cab at the time.
‘Searchers found the truck about 1,000 yards downstream from the crossing Friday night. There was nobody in the truck.’
Meanwhile the winter storm is expected to hit northeastern states on Sunday, bringing freezing rain and snow.
