Listen to local media or NOAA Weather Radio for the latest information. However, when a purple arrowhead is observed on the radar - and especially if it is preceded by and/or coincident with a long lived rotation center as indicated by a gray or purple swirl icon - a Tornado Warning is often issued. It should be pointed out that due to the curvature of the earth, it is not possible for any radar, no matter how powerful, to see what is going on directly at ground level. The purple arrowhead means that intense rotation was detected in the lowest levels of the storm, and therefore has a higher probability that it is actually extending down to the ground. Thus, it is not likely that this intense rotation has made it to the ground. The purple swirl icon simply means that intense rotation was detected, but it was located in the upper-level parts of the storm rather than near the bottom. Using the Left and Right Arrows, please select the Radar you would like to viewĪreas of particularly strong rotation are indicated by either a purple swirl icon or a purple arrowhead as indicated by the legend on the left-hand side.
