A major storm will produce blizzard conditions and very heavy snow accumulations in the Plains and Upper Midwest starting Tuesday night through Thursday, forecasters say.
'Heavy snow and strong winds will produce life-threatening travel conditions in parts of the Plains and Upper Midwest,' the National Weather Service said in a flash bulletin on Tuesday.
'The heavy wet snow may also lead to power outages,' the agency said. 'This storm is expected to intensify rapidly late Tuesday into Wednesday.'
Forecasts say that the slow-moving storm, which has up to 200 million people in its path, could dump as much as two feet of snow in places.
