It is a great feature. I live in Orlando, FL and watched the Hurricane Irma made land fall on Keys. All three models were predicting Irma would hit Tampa. That is, lesser impact on Orlando. However, the radar is showing straight northward path now. I think the Hurricane Center should update their prediction soon. I like the long hour record the best, since it shows clear path of the storm. However, the iPhone and iPad version of radar are kind of hit-and-miss missing images.
