Forward Flank Downdraft - The main region of downdraft in the forward, or leading, part of a supercell, where most of the heavy precipitation is. Compare with rear flank downdraft. See pseudo-warm front, and Fig. 7, supercell.
FFD - Forward Flank Downdraft. A region of strong downdrafts and outflow winds in the precipitation area, usually on the downwind side of a thunderstorm. The gust front is also ahead of this region.
The line normally has a stair-step appearance, with the tallest clouds closest to the main storm, and generally coincides with the pseudo-cold front.

Triple point also may refer to a point on the gust front of a supercell, where the warm moist inflow, the rain-cooled outflow from the forward flank downdraft, and the rear flank downdraft all intersect; ...
Triple Point - the intersection point between two boundaries (dry line, outflow boundary, cold front, etc.) OR a point on the gust front of a supercell, where the warm moist inflow, the rain-cooled outflow from the forward flank downdraft and ...
