ST. LOUIS COUNTY, Mo. - Weather forecasts calling for a winter storm to arrive Saturday night in the St. Louis area are leading to area agencies encouraging everyone to say home Sunday.

The threat of snow and ice is coupled with what’s expected to be multiple days of dangerously cold temperatures.

“We know temperatures are going to stay below freezing for at least a week, and that means that this snow and ice is not going to melt in a day or two,” said St. Louis County Executive Sam Page. “It will wear out its welcome, and it's going to be tough.”

“We have some concerns about power outages,” said Michele Ryan, St. Louis County Emergency Management director. “Power outages in bitter cold temperatures are even worse.”

She encouraged everyone to make sure they have emergency supplies before Sunday.

Page said The Salvation Army warming shelter is available at 10740 Page Avenue. He said residents who need a warm place to stay can call 314-423-7770 for more information or 211 for help.

St. Louis County officials are also encouraging anyone out on the road to give plow operators plenty of room to do their job.
