Since the release of Google+, Google has been slowly updating all of it’s services to conform with it’s new minimalist look. Black navigation bar on top, red text on the side, and buttons that remind me of OS X. Today they updated Google Maps to it’s new look, and added several interesting features as well.
The most significant feature that has been added is a new Weather layer, that when enabled shows current conditions in specific cities and towns. While not enabled globally, nearly the entire US is covered.
It’s nice, but I have Forecastfox for Firefox. It not only gives me temperature but also real-time weather radar. Adding such real-time radar coverage to Google Maps would be the improvement I’d suggest it needs most. The National Weather Service already has nation-wide live radar on their website, and local news stations across the US have their own as well. I could easily see Google making deals to add that content to Google maps. Granted, it might kill page load time, but it’s certainly worth experimenting with. And who knows, Google might be already.
