A massive winter storm hit the US Rockies and plains then punched east, with snow set to assault a 1,609 km corridor through the weekend, creating transportation ‘havoc’ in the middle of the country.

National Weather Service reported that the system started as rain from Mexico and turned to snow as it met icy air. Up to 18in (45cm) of snow were expected in the Sangre de Cristo mountains south of Denver, western Missouri and St Louis.

It is also expected that snow will also fall on Kansas, Arkansas and Washington before the storm hits the sea late on Sunday.

In a related context, the US authorities canceled 1431 flights, and postponed another 12465 trips with problems at a snow-affected airport such as Denver, causing negative effects across the country.

While the storm will spare the heavily populated north-east, it likely will disrupt air and auto travel from Kansas City to Indianapolis, and will bring the heaviest snowfall so far this winter to Cincinnati and the Ohio river valley, said the AccuWeather meteorologist Paul Walker.

Two weeks ago, large areas of the United States were hit by another snowstorm called Eoni, which was associated with heavy rains that killed at least seven people. (QNA)
