Many days when I visit the river the cloud formations hold my attention. I love to casually watch them form and spread and take shape. On a cloudy day I like to look for the dark spots in the clouds to see if I can see where it is raining and figure out how long it will be raining where I am.
This is a beautiful time lapse video from film maker Jack Miller for the World Meteorological Organization. It's intention is to 'bring awareness of how clouds form and interact with our weather'. More than that.. it is beautiful.
