Scene notes:

A mature tropical thunderstorm that does not have prevailing winds to push it anywhere, its first plumes have already ascended, slightly too light in density to become a dangerous storm. However, new cells are growing at its left, fed by knock-on effects from the other cell: the developing cell is pushed along by new downdrafts from the shadows of the first, while still being in direct sunlight on its growing areas of convection.
