Areas immediately to the leeward of the mountains have a microclimate with sparse precipitation called a rain shadow.

It is described as " a patch of land that has been forced to become a desert because mountain ranges blocked all plant-growing, rainy weather" On one side of the mountain the weather is wet, rainy and snowy. And on the other side (the rain shadow) there are no precipitations.
