You mean the wind velocity data directly from the doppler radar? Yeah... it turns out that wind velocity isn't super accurate for predicting where the storm is

You mean the wind velocity data directly from the doppler radar? Yeah... it turns out that wind velocity isn't super accurate for predicting where the storm is going. If you watch a storm building up over time, you'll often see it staying in one place or even moving against the wind. Almost like a traffic jam on a highway. So that's why we take a computer vision approach rather than basing it on wind-speed.
