Typically, clouds can move 30-120 miles per hour. ... For instance, high cirrus clouds can travel at a speed of more than 100 mph during the jet stream. Clouds during the thunderstorm can travel at speed up to 30 to 40 mph. The speed of the clouds is dependent on the movement of the wind.

What's it mean when clouds move fast?

Clouds are made up of water vapour, which may later fall to the ground as rain, hail or snow. The higher up you go in the sky, the faster the clouds move. This is because the wind is faster at higher heights above the surface. ... These clouds are following a particularly strong wind, called the jet stream.

What is it called when a cloud moves?

When caught in the outflow (downdraft) beneath a thunderstorm, scud clouds will often move faster than the storm clouds themselves. When in an inflow (updraft) area, scud clouds tend to rise and may exhibit lateral movement ranging from very little to substantial.
