I love storms! I live at 10th floor and have quite good views ;) A few years ago I had a phase of catching lightning (by camera), but in this LO not the lightning comes... I've been delighted incredibly dark clouds.
Ding of additives emphasize the thick, stifling atmosphere before a storm, crystals and splashing announce the eagerly awaited rain.
