18 August 2007

Wall cloud/supercell associated with the remnants of tropical storm Erin. This storm displayed classic supercell structure on radar, though it was difficult to observe from the ground given the very low cloud bases and precip. Unlike most tropical cyclone supercells, this storm had frequent LTGCG W-N-NE of the mesocyclone.
