As Hurricane Irene was approaching Puerto Rico, I noticed that the National Hurricane Center posts mapping layers for each element in their storm-track forecast maps.
Since their zoomable maps aren't embeddable, I made one that is. Feel free to use it:
Right now, I'm manually updating the map with new layers as they are issued, every three hours. I'm pretty close to having a script ready to handle that for me, based on information in the storm's RSS feed.
In the process of building this map, I learned how to use "listeners" to dictate the order the layers are rendered. For anyone trying to work that out, here's the code for how I did it.
