I came across Weatherbonk yesterday, while doing some research on building a google maps style application for a client.
It’s a very cool site, that tells you the weather forecast using google maps. It even knows to default the map to where you currently are (in my case I am in China this week). You also get live Web Cam feeds from the nearest cameras to your location, and the site shows traffic maps as well. I also love the ability to track weather on a given route .. which would be useful for the transport industry. For golfing or skiing fans, they have sister sites called Golfbonk and Skibonk
Perspective: It’s great to see more and more tools providing first hand information tailored to your needs.
