Severe weather storms move through US

A huge storm system is moving across the US, which could impact more than 150 million people with tornadoes, flooding, wildfires and blizzard conditions. AccuWeather manager Bill Wadell joined Sky News Australia to discuss the sprawling storm system crossing the US and the areas at high risk of being affected. Mr Wadell warned that the center of the country, including the Mississippi Valley and the Gulf Coast, is at the greatest risk of seeing tornadoes over the next few hours. He revealed that a confirmed tornado has already been reported in Missouri, with hail larger than five centimeters also being reported.
