Storm Will Plant A Wet One On San Diego This Valentine’s Day

Not to take the romance out of Valentine’s Day, but this year a sturdy umbrella might be a better gift than chocolate or flowers. The National Weather Service says a huge, warm plume of moisture from the sub-tropics will arrive in San Diego County and drench a region that’s already squishy from earlier storms. The system will begin spreading rain late Wednesday. But the core will hit on Thursday — Valentine’s Day — when the moisture rides up the side of local mountains, condenses, and unleashes heavy rain. Its called orographic lift.

Massive Response After Rancho Bernardo Creek Turns Purple

Connie Bakken opened her bedroom window Sunday morning and didn’t quite believe her eyes. “I called my husband and said, ‘Why is the stream purple?” she says. Bakken lives in a Rancho Bernardo home that overlooks a creek just west of Matinal Circle. What she saw – the creek where she loves to watch turtles and crabs live naturally turn into a deep, unnatural purple. “It didn’t look like water,” Bakken says. “It actually looked like purple paint.”

Massive Bird Die-Off At Salton Sea Raises Environmental Concerns

Thousands of birds were discovered dead at the Salton Sea last month, raising new concerns about the lake’s declining health. California Department of Fish and Wildlife workers cleaned up the carcasses at the Sonny Bono Salton Sea National Wildlife Refuge after hunters initially reported the gruesome bird die-off. More than 400 species of birds use the Salton Sea’s wetlands as a stop along the Pacific flyway for migratory birds. The man-made Salton Sea is receiving less and less water from agricultural runoff and the Colorado River, causing it to shrink dramatically. Andrea Jones, director of bird conservation for Audubon California, said the birds fell victim to avian cholera, a contagious disease, due to overcrowding.

American Canyon Keeps Sites Reservoir In Its Sights

American Canyon will continue looking to the proposed, massive Sites reservoir in Colusa County to someday help slake its thirst. The city of about 20,000 residents is the only Napa County city without a local reservoir. It depends on the state’s North Bay Aqueduct that pumps water out of Barker Slough, a dead-end slough in the Solano County portion of Sacramento-San Joaquin Delta. Supply reliability is tied to the Sierra snowpack that melts and sends water into the state’s Lake Oroville reservoir that feeds into the Delta. From year to year, it’s wait-and-see how much of the American Canyon allocation will actually arrive.

An Atmospheric River Could Bring Torrential Rainfall To California Over Several Days This Week

California has all the elements in place for nasty flooding because of an “atmospheric river” event: Waterlogged soil from an already-wet winter? Check. Many square miles of land scorched by fire? Check. A thick snowpack on the mountaintops? Check. And wouldn’t you know it, the hours are ticking away before another atmospheric river makes landfall somewhere in the Golden State. Welcome to West Coast winter 2018-2019, responsible for a snowbound Seattle (the most snow in February since the Truman administration), a soaked Los Angeles (its wet season rainfall exceeding 13 inches, more than 50 percent above average) and totally stoked skiers in between.

California’s ‘Dry Farmers’ Grow Crops Without Irrigation

Jim Leap fondly recalls the first Early Girl tomatoes he grew at UC Santa Cruz’s farm in 1990. Sweet and bursting with flavor, they were raised without a single drop of irrigated water. Nearly three decades later, he remains deeply committed to “dry farming” — forsaking modern irrigation and relying on seasonal rainfall to grow tomatoes, winter squash, potatoes, dry beans and corn on the 4-acre San Juan Bautista farm that Leap and his wife, Polly Goldman, have owned for eight years. “What motivated us to dry farm was the environmental ethic,” Goldman said. “We are not using city water or groundwater.”

Midweek California Storm To Bury Sierra Nevada Under Yards Of Snow, Bring Flooding Risk

One of the more potent storms of the winter will hit California with heavy rain, excessive mountain snow and gusty winds from Tuesday night to Thursday night. The worst of the storm is forecast to focus on Central and Northern California with a heightened threat of flooding, mudslides, erosion, power outages and avalanches and road-closing snowfall in the mountains.

Atmospheric River Possible Next Week For California, Raising Flood Concerns

Computer models are showing a growing likelihood of an atmospheric river storm hitting California late next week, raising concerns that if a warm “Pineapple Express” barrels in with enough force, it could melt parts of the state’s big Sierra Nevada snow pack and increase flood risk. Atmospheric scientists and meteorologists say more will be known in a few days. The storm could still fizzle the way hurricanes that develop far out in the Atlantic Ocean sometimes fail to materialize or make landfall.

Salton Sea: Fish And The Birds That Fed On Them Wiped Out This Winter

Tim Bradley crunched across a broad beach made of dead barnacles and fish bones. He bent down and stirred green slime, tinged with brown foam at the western edge of the vast lake unfurled before him. It was a sign for the longtime biologist that the much-maligned Salton Sea is alive. “It’s just algae and bacteria and scum and so forth, but it’s an incredible thing, because this could be a very productive site,” he said. “The water is so full of nutrients. See those bubbles there? The only question is, what’s going to take advantage of that?”

Wet Winter Greatly Reduces Drought Conditions In California

A very wet winter has greatly reduced drought conditions in California, but Ventura County isn’t out of the woods yet. The U.S. Drought Monitor reports that more than 34 percent of the state including the Sierra Nevada, much of the Central Valley and the San Francisco Bay Area is free of any significant dryness. Ventura County is in a portion of the state rated as “abnormally dry” after rain eased the “moderate drought” rating for an area that stretched from the Central Coast down through the southern tier of the state.
