How it came to be

As a resident of Florida, I have lived the experience that “waiting for a hurricane is like being stalked by a turtle.” I would grab images of the National Hurricane Center’s famous “probability cone” for (most) storm updates and build animations to watch how they develop. At some point it occurred to me that a bot could do this work. Once I had the animations, I asked it to render the actual track, and I could watch how predictions more or less matched reality. Finally, I added the “wind footprint” to the animations, and I had a “product” I had not seen elsewhere.

I started with storms of interest to me, and add new storms to this animation as time and usage quotas allow. I hope you have fun with this viewer. Feedback, including a storm of particular interest to you, is always appreciated.

All storm data comes from the National Hurricane Center.

How to use it
