A heavy late afternoon rain approaches our Puku Ridge tented camp. I intensify the overwhelming presence of that huge rain cloud by wrapping it in overhanging leaves, limiting the space through which it must pass. There are more clouds than space in this shot, and it is that juxtaposition that gives this image its tension and power. And yes, when the rains came, they came with high winds and great energy. But the stronger the rain, the more quickly it ends. The typical summer rain in Zambia lasts for an hour or two, generally between five or six in the afternoon and seven or eight at night.
