Waze boasts a great user-friendly interface. If you're already familiar with the app, look for this new feature by selecting the “Report” icon, then “Hazard,” then “Weather.” Under the weather hazard, you'll see options for fog, hail, flood, ice on road, and unplowed road.
Simply plug in your starting and ending points and select your route. Once you choose your route, the weather along it is displayed using data from the National Weather Service. The application displays icons depicting cloud cover, precipitation, fog, hail, smoke, haze, snow, thunderstorms, temperature and wind.
