That link should work after a storm begins to form. I believe the first formation will be AL90.
Also seen in the left sidebar, second section from the top.
I understand that this link should not return anything now as there nothing to return.
My question was what is the format of the returned xml file. In other words what would be between the <currentstorms> tags if there were active storms.
I need this information because I would like to update our web portal very 2 or 3 hours with this information.
