WeatherUnderground no longer offers free developer API keys
Get access to the world's most accurate, precise and trusted weather data
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.
With The Weather Company, you can take advantage of these packages quickly and easily, accessing weather data APIs via the Cloud. The packages are curated to give you only what you need in the format you need it. 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.
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. If you have been directed to download our Weather Underground free API key by a third party provider, please contact your vendor for resolution.

Thanks so much for bringing this issue to our attention.
The teacher's notes for each video in the last stage of this course have been updated with information (including code) about how to use the OpenWeatherMap API in place of the Weather Underground API.

The forum is a great place to communicate with other students, but may not be the most expedient (or even certain) way to contact the staff.
This sounds like something that the staff should be aware of. You can contact them directly as described on the Support page. They'll probably want to post something to the Teacher's Notes.
