An atmospheric river, a ribbon of moisture-laden air that can ferry water thousands of miles across the sky. When the tempest hit, the state was on the brink of an exceptional drought. But instead of storing the surge the storm brought for the dry days to come, the reservoir’s owner, the US Army Corps of Engineers, let it run downstream.

Despite the fierce rains and deadly mudslides that have struck California, water officials are concerned about the possibility of a renewed drought. But they caution that is too early to tell. Frank Gehrke, chief of the California Cooperative Snow Surveys Program, measured snowpack levels with a team last week in the bare Phillips Station area of the Sierra Nevadas, about 90 miles east of Sacramento.

The recent fires and rains in Southern California have led to mudslides, debris flows and rock falls along the Santa Barbara County coast. At least 17 people have died, dozens of homes have been destroyed and, in the coastal village of Montecito, the water system was severely damaged. With extreme weather becoming the norm in California, Take Two reached out to Stanford University earth science professor, Noah Diffenbaugh, to learn more about the state’s infrastructure and its level of preparedness for natural disasters.
