This is 2133 UTC when the NMDA was maxed out with 8 tilts (0.5 – 5.1) being incorporated into the detection. Rotation track at the upper left shows how quickly this escalated.

Below is a jump ahead to 2146 UTC. Through this time, the NTDA was very consistent with tracking the circulation even as depicted in leftward curving rotation track.
