Services
Weather Underground also uses observations from members with automated personal weather stations (PWS).[22] Weather Underground uses observations from over 250,000 personal weather stations worldwide.[23]
The Weather Underground's WunderMap overlays weather data from personal weather stations and official National Weather Service stations on a Mapbox Map base and provides many interactive and dynamically updated weather and environmental layers.[24] On November 15, 2017, users were notified by email that their worldwide, user-provided weather cameras would cease to be available on December 15, 2017. However, on December 11, 2017 users received another email from Weather Underground announcing that they were reversing their position and would not be discontinuing the service based on significant user feedback.[25]
The service previously distributed Internet radio feeds of NOAA Weather Radio stations from across the country, as provided by users, and had a Weather Underground Braille Page.
The Associated Press uses Weather Underground to provide national weather summaries.[26]
Weather Underground has several Google Chrome extensions[27] and applications for iPhone, iPad and Android[28] including FullScreenWeather.com, a redirect to a full screen weather viewer tied into OpenStreetMap. There was an app developed for Roku devices, which has been deleted.[29]
In February 2015, Weather Underground released an iOS app called Storm.[30] This app is universal, and can be used on both iPhone and iPad. Other apps by Weather Underground include WunderStation[31] for iPad and WunderMap[32] for iOS and Android. In 2017, Weather Underground removed support for Storm, in favor of the "Storm Radar" app released by The Weather Channel Interactive in June 2017.[33]
On December 31, 2018, Weather Underground ceased offering its popular application programming interface (API) for weather data, further reducing the breadth of its services.[34]
On September 10, 2019, Weather Underground announced the discontinuation of its Email Forecast Program as of October 1, 2019, continuing the reduction in services noted above.[35]
