National Weather Service Travel Forecast - Experimental!


Winter will be upon us soon, and with that comes hazardous traveling conditions. We want you to be prepared and stay safe this winter so we are are testing a new webpage that will display our National Weather Service forecasts along South Dakota highways and interstates. Road segments are color coded based on forecast weather in 6 hour time intervals. Selecting a road segment provides detailed forecast information. The forecast is for planning purposes only and you should call 511 or navigate to for current road conditions across South Dakota. This page is experimental so it is subject to change at any time.
