TVS?
I see this in GRLevel3, but I don't know what it means. I believe it indicates a tornado/funnel cloud, but I say that because of the pink upside-down triangle. Can anyone explain?

SPC states that it means this.
TVS - Tornadic Vortex Signature. Doppler radar signature in the radial velocity field indicating intense, concentrated rotation - more so than a mesocyclone. Like the mesocyclone, specific criteria involving strength, vertical depth, and time continuity must be met in order for a signature to become a TVS. Existence of a TVS strongly increases the probability of tornado occurrence, but does not guarantee it. A TVS is not a visually observable feature.
