The world's first online weather service, Weather Underground is committed to delivering the most comprehensive, reliable weather information possible. Weather Underground's collection of over 1.5 million user-contributed photographs and its network of webcams are also available as a data layer so archived images can be viewed alongside the weather. In addition to selecting specific date ranges, users can simply jump through time by adjusting the year, month, day, or hour.

The most significant feature upgrade on the WunderMap® is the more robust time bar that allows users to utilize a slide rule navigation tool to select and change date ranges, creating custom weather animations. 'The new user interface makes switching between different data layers and using the map settings even more intuitive.' 'WunderMap® is the ultimate online resource for in-depth weather information and its many data layers provide users with an unrivalled interactive experience,' said Alan Steremberg, President and co-founder of Weather Underground. Each layer option has its own settings menu that allows the user to fine-tune the data they are viewing. The new user interface has been designed to keep the navigation process as simple as possible while also presenting the vast amount of data that users can overlay on the map. WunderMap® uses the latest Google Maps API so that users can zoom in to a local level and view Weather Underground's unique network of neighborhood weather stations or zoom out to view weather patterns as they affect a region or continent.

The map can also look into the future and display forecasted weather conditions for up to 10 days, including 6 hours of radar. Archived radar spans back to 1994 while significant tornadoes can be tracked back as far as 1950. Users can set specific dates back in time or use the search function to view historically significant storms such as Hurricane Katrina or Hurricane Sandy.
