Climate Scientists See Alarming New Threat To California

California could be hit with significantly more dangerous and more frequent droughts in the near future as changes in weather patterns triggered by global warming block rainfall from reaching the state, according to new research led by scientists at Lawrence Livermore National Laboratory. The latest study adds a worrying dimension to the challenge California is already facing in adapting to climate change, and shifts focus to melting polar ice that only recently has been discovered to have such a direct, potentially dramatic impact on the West Coast.

Portable Treatment Systems To Create First ‘Virtual Water District’

One of the hard truths revealed by California’s five-year drought is that many small, rural communities lack the resources to adapt to water shortages. In this case, that means both money and expertise. It can be very expensive, for instance, to build a new water treatment plant or connect with one in the next closest town. Even if a community finds the money to build a small treatment plant, it may not have anyone locally with the expertise to operate it.

 

Southern California’s Wet Season Has Started Dry and No Rain Relief Is in Sight

Southern California has begun its annual wet season with paltry amounts of precipitation so far, and the forecast does not bode well through at least the middle portion of December. Strong Santa Ana winds gusting to near 80 mph this week have made conditions worse by fanning destructive wildfires in Southern California. Los Angeles has seen just 0.11 inches of rainfall since Oct. 1, which ranks as the 11th-driest start to the wet season in 141 years of records, according to meteorologist Bob Henson of wunderground.com.

What Could Cause California Droughts? Melting Sea Ice

Polar bears aren’t the only ones in trouble from the Arctic’s melting ice. A new study by Bay Area scientists concludes that Californians could face reduced rainfall — and worse droughts — by the continuing loss of sea ice. Their computer analyses show a 10 to 15 percent average decrease in California’s rainfall in the coming decades. The culprit, scientists now believe, is a link between the melting ice and the buildup of massive high pressure systems that park off the California coast and block Pacific storms.

Cold But No Rain In Immediate Forecast. Is California Having a Dry Winter?

What happened to the rain? Less than a year after the drought was declared over, precipitation has been relatively scarce in the Sacramento area and Northern California so far this season. This week’s cold snap is accompanied by a round of dry weather that’s expected to last at least another 10 days. It’s too soon to panic about a prolonged dry spell, however.

Wild Winds, Low Humidity, Could Spread Wildfires Across This Week

The National Weather Service has issued a red flag fire weather warning for the coast and a wind advisory for the rest of San Diego County due to the onset of four days of Santa Ana winds and low humidity. Forecasts say the winds will peak Monday night into Tuesday morning and Wednesday night into Thursday morning. The winds will blow 20 to 30 mph with gusts to 55 mph, and isolated gusts of 70 to 80 mph at a few of the county’s highest peaks.

OPINION: A Test Of California’s Commitment To Groundwater Sustainability

Throughout California, access to water and how it is distributed is a perennial issue. Water conflicts are often nuanced and take on a life of their own. In some cases, a local conflict can have statewide implications — the City of Marina, a small city along the shores of Monterey Bay, finds itself in such a conflict. In 2009, the California State Water Resources Control Board ordered the private, for-profit California American Water Company to end its illegal water diversions from the Carmel River.

California Water Districts Don’t Need Voter Approval On Fees

The state’s water conservation districts don’t need the approval of property owners or voters to charge their customers fees to fund programs aimed at protecting groundwater, the California Supreme Court ruled on Monday. But the justices in a unanimous decision also said the districts cannot charge cities disproportionately more than farmers for conservation efforts. The decision ensures the water districts have a source of funding to undertake projects to replenish ground water — a key irrigation source for farmers that became even more vital during California’s historic drought.

Longest And Strongest Santa Ana Winds Bring Fire Danger To Southern California

Dry and gusty Santa Ana winds sweeping through Southern California are predicted to bring days of critical fire weather conditions. Red Flag warnings by the National Weather Service began late Sunday and will last through Thursday. Meteorologists say relative humidity levels will plunge into the single digits and teens. Officials have dedicated extra resources to fire-prone areas. Forecasters say it could be the strongest and longest Santa Ana wind event so far this season, with gusts capable of bringing down tree branches and power lines.

Metropolitan Water District Approves Repair Of Lake Mathews’ Forebay Lining And Outlet Tower

The Metropolitan Water District of Southern California approved the repair of the forebay lining and outlet tower at Lake Mathews. The Nov. 14 MWD board vote awarded a $3,248,000 contract to J.F. Shea Construction for the work while appropriating $4,570,000 for the project. The board action also found the project categorically exempt from California Environmental Quality Act review.
