Tail Doppler Radar (TDR) data from the current recon mission into Melissa shows that the vortex is vertically stacked up to 15 km w/ the upshear/NW quad being the strongest.

This is about as favorable of a vortex structure as you’ll see for rapid intensification

Ever seen a “volnado” before?

Check out this video from USGS of a whirlwind kicking up loose ash deposits along the active fountain and flow within the Halemaʻumaʻu crater of Kilauea!

According to USGS, these whirlwinds have been documented during several eruptive episodes downwind of the eruption
