Atmospheric rivers like the one hitting California this week are forecast to happen more often in the next century. That’s according to a recent study published by Doctor Corinne Bowers, who recently earned her Ph.D. in civil engineering at Stanford University. The storm sequences are also predicted to be more intense, last longer, and may happen in places that haven’t seen them before. The study says the chance of “super sequences,” which last longer than 60 days, could also increase. Because soil is already saturated, a storm can cause three times more damage if happens during a sequence of storms than if it happens alone. Experts say there was evidence of this in California last winter.
