Weather Underground recently announced that their current weather api for developers will end in late December 2018.
It appears that they will be rolling out a new platform at the same time so that may explain why they have let their websites deteriorate. As a hobbyist web developer I hope they continue to support the pws community and the many developers that depend on Weather Underground. If anyone has any insight into WU's plans please post a reply.
I developed a mobile friendly web page using WU's api. Any feedback would be appreciated. I plan on revamping the site early next year.
