Google has added weather forecasts to their growing list of services. The weird thing is, it’s only available for US locations. Google Maps being US only is understandable. But, weather information from all around the world is already available on The Weather Channel. I wonder why they chose Wunderground, which is a US only service, as their source. Maybe it’s because they’re pitching it as a way to get weather info through the phone too (SMS), which isn’t available elsewhere. Still, a web only forecast shouldn’t have been a problem for other locations. As far as I know, The Weather Channel doesn’t charge anything for the data, as many browsers make use of extensions and sidebars which pull in data from there.
