Caption: Timelapse footage of fast-growing cumulus clouds with pileus clouds at their tops. Pileus clouds appear as wispy horizontal caps, and form as the rising air in the cumulus clouds pushes moist air upwards, causing it to condense. They are indicative of powerful updrafts, and therefore a good sign of an impending storm. Filmed in Colorado, USA, in summer.
