A winter storm warning issued by the National Weather Service remains in effect in until 7 a.m. For much of central and north central Iowa; a winter weather advisory remains in effect for Iowa. North-northwest winds of 20 to 30 mph with gusts near 45 mph are expected to cause blowing snow, reducing visibility to less than one-half mile at times.

Iowa’s 511 system is presently reporting that roadways in the Correctionville, Denison and Ida Grove areas are impassible. Roads in western and northeast Iowa are partially to completely covered snow covered. Travel remains hazardous along Interstates 29 and 80 in western Iowa, and also east of Mason City and north of Waterloo.

Unsafe conditions for snowplow operators in keeping roadways open caused the many of Iowa DOT’s maintenance garages to suspend operations across the state. Operations in these areas are scheduled to resume as day light appears and as the wind conditions lessen.

Motorists should exercise extreme caution during the morning commute and while otherwise traveling this morning. Remember, “Don’t Crowd the Plow,” and make sure to carry appropriate winter survival items in your vehicle.
