Weather Underground Mashup displays flood alerts for rivers across the United States. Announced today by Weatherunderground, this new web service alerts users of Flow Rate, Percentile, Current Stage, Forecast Stage and Flood Stage.
About the app... Using data from the USGS (the US Geological Survey), the product plots river data and forecasts on top of an interactive map. Users can scroll across the country and zoom in and out to view in-depth observations from all major rivers in the US. Alternatively, one can click an option to view only the rivers with current flood alerts. See www.wunderground.com/wundermap/rivers
