A storm system moving toward Southern California will bring a “long period” of steady rain across the region this week and could trigger debris flows in recent burn areas, forecasters said. The storm is expected to drop 2 to 4 inches of rain along the coast and in the valleys in Los Angeles, Ventura and Santa Barbara counties, and 4 to 6 inches in the mountains between Tuesday afternoon and Thursday morning, said Todd Hall, a meteorologist with the National Weather Service in Oxnard. South-facing slopes could see up to 8 inches in some areas.

Despite another hot and dry year with less than four inches of rain in the Los Angeles area, we are back to our water-wasting ways. Two years ago, Californians were using 24% less water compared with 2013. This year, we’re hardly conserving at all — just 1%. Clearly, our earlier successes were more behavioral than structural. If lawn removal and new efficient fixtures and appliances had saved all that water, we wouldn’t be seeing this momentous backslide.
An atmospheric river that forecasters are billing as the biggest storm of the season is expected to drench Southern California beginning Tuesday night and will bring with it the potential for mud flows and widespread flooding, the National Weather Service said. The storm, which is fueled by warm, western Pacific waters, will deliver nonstop rain across much of California and provide some relief to areas that have seen a resurgence in drought conditions.
Members of the San Diego Regional Water Quality Control Board gathered in a closed session on Monday afternoon, debating whether to file a lawsuit against the federal government to stem the cross-border flow of sewage, sediment and other contaminants from Tijuana to San Diego. The deliberations followed a lawsuit filed earlier this month by the cities of Imperial Beach, Chula Vista and the Port of San Diego against the U.S. International Boundary and Water Commission, alleging violations of the Clean Water Act and Resource Conservation and Recovery Act.
Democrats in Congress have stalled an attempt to jump start an expansion of Shasta Dam, California’s largest reservoir and a major water source for the Central Valley. Their objections blocked a Republican gambit to allow the $1.3 billion project to move forward without full up-front funding and despite objections from Gov. Jerry Brown’s administration. A Democratic leadership aide in the House confirmed to the Sacramento Bee on Monday that House Democrats rejected a GOP proposal to speed preparations for the project, by eliminating a requirement on the amount of upfront funding needed for pre-construction.
An already dry winter for the Colorado River has gotten worse in recent weeks, but it won’t be enough to send Lake Mead to a record low — at least not right away. Despite worsening conditions in the mountains that feed the Colorado, forecasters still expect the reservoir east of Las Vegas to contain just enough water by the end of the year to avoid a first-ever federal shortage declaration. A month ago, the Colorado River Basin was on track for its seventh-driest winter in more than half a century.
Heavy rain and snow is in the forecast for California this week including local areas that are at risk of mudslides because of recent wildfires. But there is an upside. All that precipitation is chipping away at a snowpack deficit in the Sierra Nevada mountains – the source of one-third of the state’s drinking water supply. December, January and February were unusually hot and dry. But March has been a different story. Since the beginning of the month, the Sierra snowpack has gone from 23 percent to 48 percent of average in terms of its snow to water equivalent.
An atmospheric river is predicted to dump more rain on Southern California and the Central Coast than any other storm this year, and is expected to drop up to 4 feet of snow in the Sierra Nevada and 2 inches of rain in Sacramento before dissipating over the weekend. The National Weather Service expects a weak preliminary storm to hit Tuesday afternoon. Light rain and snow above 5,000-6,000 feet elevation is expected before a short break Wednesday morning, followed by a second system’s arrival that afternoon.
