Bettina Boxall writes in the LA Times about “the perfect drought”:

Nature is pulling a triple whammy on Southern California this year. Whether it’s the Sierra, the Southland or the Colorado River Basin, every place that provides water to the region is dry.

It’s a rare and troubling pattern, and if it persists it could thrust the region into what researchers have dubbed the perfect Southern California drought: when nature shortchanges every major branch of the far-flung water network that sustains 18 million people.

Usually, it’s reasonably wet in at least one of those places. But not this year.

The mountain snowpack vital to water imports from Northern California is at the lowest level in nearly two decades. The Los Angeles area has received record low rainfall this winter, contributing to an early wildfire season that included Friday’s blaze in the Hollywood Hills. And the Colorado River system remains in the grip of one of the worst basin droughts in centuries.
