This graphic is about Atmospheric Rivers i.e. thick concentrated movements of water moisture. More explanation on Atmospheric Rivers can be found by clicking here or if you want more theoretical information by clicking here.

This raises the potential for extreme precipitation events. You can convert this graphic into a flexible forecasting tool by clicking here.
