What does a storm cloud weigh?

![]( =320x) Since this is the season around here for frequent thunderstorms.. I thought it might be interesting to look at what a typical storm cloud might ‘weigh’. These things are floating above our heads.. and it’s just not something most people ever think about. They are all unique of course.. so here are some baselines. A storm cloud that is 1 sq/mi and 33k feet tall (medium height for what we get this time of year) with an average density would hold about 563 million pounds of water.
