I will pass along information as I get it. It may be that WU allows those of us with existing keys to continue to use the service, but I don't know much yet. Unfortunately, I don't yet know what this means for the WUnderground and WUnderstation plugins. If you have been directed to download our Weather Underground free API key by a third party provider, please contact your vendor for resolution. To improve our services and enhance our relationship with our users, we will no longer provide free weather API keys as part of our program.

You can Incorporate weather data into your applications or combine business data with weather data such as alerts and notifications, forecast data, and weather imagery, then apply advanced analytics to build the foundation for informed enterprise decision-making. The packages are curated to give you only what you need in the format you need it. With The Weather Company, you can take advantage of these packages quickly and easily, accessing weather data APIs via the Cloud.

Weather Underground as part of The Weather Company, an IBM business, now offers a series of Data Packages that tap into the breadth and depth of weather data to provide current and forecast conditions, seasonal and sub-seasonal forecasts, lifestyle indices, severe weather and historical weather data.
