Winter reporting is off for the season. Iowa DOT publishes segment-by-segment snow and ice conditions from October 15 to April 15; outside that window the feed changes only as needed. Our own forecast below runs year-round.

Conditions are entered by Iowa DOT maintenance staff and describe what is on the pavement, not the forecast; what each term means is on the Iowa page. Always check with Iowa 511 before setting off.
