A raging winter storm that dumped snow in parts of the Midwest over the weekend moved eastward Monday, leaving some highway and air travelers stranded and promising even more snow and brutal cold.

In northwest Indiana, at least two counties declared a state of emergency and urged drivers to stay off the roads. Police and highway crews struggled to dig out some stranded motorists and clear roads covered with blowing and drifting snow.

LaPorte County Sheriff's Deputy Patrick Drangmeister said several motorists remained stranded Monday morning in various locations throughout the county. He said every available deputy was out trying to help. A state of emergency was in place, with motorists urged to avoid all but highly essential travel.
