OMAHA, Neb. (AP) — Travel remains difficult in eastern Nebraska and much of Iowa after a strong winter storm moved across the area.

Iowa officials closed Interstate 35 between Ames, Iowa, and the Minnesota border on Sunday because of blowing and drifting snow. The storm dropped several inches of snow on central Iowa, but parts of northwest Iowa received as much as 16 inches of snow.

In Nebraska, Interstate 80 remained closed Sunday between Grand Island and Gretna just southwest of Omaha because of weather conditions and several crashes. Much of eastern Nebraska received between 6 and 10 inches of snow in the storm.

Forecasters warn that even though the snow has stopped falling in Iowa and Nebraska strong winds could still cause blizzard conditions.

Many churches canceled their Sunday services because of conditions.
