In a nutshell, there are thin lines in the atmosphere which contain much of the rainfall that falls each year. They are called rivers because that’s kind of what they look like from space. There are less than a handful of these rivers around at any one time, but they can be thousands of kilometres in length.
If conditions are right, they drop some of that moisture on land. The west coast of North America is particularly susceptible. Every once in a while, the amount of precipitation reaches the critical level, leading to long and heavy rainfall.
