And this cyclone brought along a big friend. Below, or to the south of the cyclone, is a long line of clouds, known as an atmospheric river. These are formidable bands of moisture that often deluge California with potent rain and snow, sometimes to damaging degrees. Spinning mid-latitude cyclones often drive these long bands of moisture, as they pull the atmospheric river behind the storm, explained Weber.
In this case, the bulk of the atmospheric river, also dubbed a "river in the sky," has slammed into Baja California, Mexico's long, wild peninsula.
