Foreca Content Usability
A very well done mobile weather site. It's truly international, claiming to cover 80,000 locations. I was able to bring up detailed forecasts for every city I tried including Havana, Nairobi, Oslo, Chengdu and San Francisco. For each location Forca provides daily and 7 day forecasts and animated GIF maps showing radar and satellite views as well as temperature, precipitation, clouds and wind.
