Cumulonimbus clouds build upward in a blue sky with telephone poles below.
A daytime view, looking up at a blue sky with a large grouping of cumulonimbus clouds. The clouds have flat bottoms and are darker gray on the bottom. They have lift and fluffy white tops. The clouds are building up toward the upper left. Three smaller cumulonimbus clouds are in the very bottom right corner. Two slightly larger clouds are in the bottom left corner. Both have a gray bottom half that is cut off by the bottom edge and left corner of the frame. Two traditional telephone poles with two crossbars are visible holding up their lines. They extend from the bottom right edge, close to the corner. The telephone lines run across their tops, from the lower middle right edge to the bottom right edge.
