Snowfall expected this evening prompted the city of Ames to schedule the snow ordinance to go into effect at 8 a.m. Monday, Jan. 10.

The National Weather Service has issued a winter weather advisory beginning Sunday for northwestern Iowa, including Story County. The advisory is in effect until 6 a.m. Tuesday.

The forecast from the National Weather Service calls for moderate to heavy snow in the next 48 hours. Totals could reach 5-9 inches and the snow is expected to be followed by blowing snow on Tuesday.

The city of Ames snow ordinances go into effect when two inches of snow fall on major arterial streets.

Snow routes are marked by red and white, or red, white and blue signs, and vehicles parked on snow routes may be ticketed and towed. All vehicles should be moved to off-street parking or to streets that are not designated snow routes, according to the city of Ames.

The city said it is important to remember the snow ordinance remains in effect until the streets are completely plowed from curb to curb, and it has stopped snowing.

To assist in the plowing efforts, all Ames residents are asked to remove parked vehicles from residential streets. However, only those on snow routes are required to move them.
