State officials in Oregon say landslides and high water have closed parts of many state highways. That’s after being hammered by a heavy rain storm – the kind scientists call an “atmospheric river.” In most years, West Coast states count on four to six of these super-soakers for as much as half of their annual precipitation.

Scientists have a lot to learn about these storms, including how they form and what makes them so strong. The best way to study the storms is by flying into them head-on. Danielle Venton from Here & Now contributor KQED climbed aboard one of the research planes and brought back this report.
