More Rain Expected For Soggy South Bay Cities

Another atmospheric river hovered over the South Bay early Monday, dumping about an inch of rain along the coast but stopping short of causing any major damage. An overnight countywide flood advisory was canceled by 9 a.m., but a similar storm was expected to roll in Tuesday and hang around into Wednesday, when high pressure brings fair and warmer weather, according to the National Weather Service. Forecasters another storm may deliver more rain Friday into the weekend.

AZ Conservation Deals Seek To Prevent Lake Mead Shortages

Water levels in Lake Mead, which stores water for Arizona, California, and Nevada, have plunged in recent years.  If levels drop below a certain point, they trigger an official shortage.  But as Maya Springhawk Robnett of the Arizona Science Desk reports, the three states are trying to avoid that… Federal water managers say there is a 50/50 chance water levels in Lake Mead will fall below one-thousand-seventy-five feet above sea level, or about 35% capacity for the reservoir.  That’s the point at which federal rules will kick in mandating radical cuts in water taken from the Lake.

California Storms Could Trigger Floods, Mudslides And Bring 120-mph Winds, Forecasters Warn

The storms didn’t pack the punch of the atmospheric rivers that swept across California in January. But the first of two storms that arrived before sunrise Monday dropped much welcomed rain and snow from the Sacramento Valley and Sierra Nevada down to San Diego County. After years of sustained drought, California’s landscape has been inundated with storm after storm since the beginning of the water year in October.

 

Municipal Water District Of Orange County Wants To Take ‘Emergency’ Out Of Drought

The drought panic is over – at least that’s what one water agency is declaring. On Monday, the board of directors for water wholesaler Municipal Water District of Orange County voted unanimously to declare an end to emergency drought conditions in Orange County and requested the state do the same. The move comes days after another water agency, in San Diego, declared an end to drought conditions and asked the state to end emergency regulations.

 

Rain in Southern California Triggers Flood Advisory, Concerns Of Mud Flows In Foothills

The first of two rainstorms to hit Southern California this week arrived before sunrise Monday, dropping more than an inch of rain in Ventura County and triggering concerns of mud flows in the city of Duarte. The storm is expected to let up this afternoon, said National Weather Service meteorologist Dave Bruno, but a second spell is expected overnight into early Tuesday. Even though the rainfall hasn’t been heavy compared with a series of atmospheric rivers that slammed California in January, it has sparked some concerns about overwhelming burn-scarred hillsides in the San Gabriel Valley.

‘State of Extremes’: What to Make of California’s Weather

A dry El Niño year followed by a wet start to what is expected to be a dry year in Southern California has raised questions about California’s climate. California is a state of extremes when it comes to precipitation, which has alternated between drought and excessive rain throughout recorded history. Los Angeles, for example, has an average of 15 inches of rain a year, even though the city rarely nears that amount. In the past 30 years, Los Angeles has gone from extremely dry years to well above average years of rain, which results in the 15-inch average overall.

 

California’s Wettest Drought? – 2017

Wet.  After five years of drought, most of California finally has become wet.  The mountains are exceptionally wet and covered with snow.  The state’s reservoirs are fuller than their long term average (with a few exceptions).  Flood control structures are being employed, some for the first time since 2006. We can now better understand the balance needed for California’s water system – which must operate for many sometimes-conflicting purposes in a climate with wild swings in water availability.  Every year, California must operate for drought, flood, public and ecosystem health, and economic prosperity (or at least financial solvency).

Plan For More Wind and Rain This Week

If you’re planning your outfits for the coming week, sweaters, raincoats and umbrellas are a sure bet. No one likes to wear squishy wet socks, so consider lacing up the kind of sensible shoes that can ward off puddles, because there is likely to be a lot of them this week. Forecasters are predicting 2 inches of rain by Wednesday alone. And more rain is coming with storm No. 3 on Thursday and Friday.

$900M Folsom Dam Spillway Project Nearing Completion

The Folsom Dam auxiliary spillway project is in its last phase and on schedule to finish by October, according to the U.S. Army Corps of Engineers, Sacramento District.The $900 million structure, which runs parallel to Folsom Lake Crossing, has been in construction since 2008 and is a joint project between several federal and state agencies: the U.S. Army Corps of Engineers, U.S. Bureau of Reclamation, State of California and Sacramento Area Flood Control Agency. The Corps of Engineers built the dam, while the Bureau of Reclamation excavated the spillway chute and will operate the dam when it is finished.

Does The ‘Blob’ Foretell North Pacific Future?

There is good news and bad news about the big warm-water “Blob” that has wreaked havoc on the North Pacific for the past three years, an expert told fellow scientists at the Alaska Marine Science Symposium in Anchorage. The good news: The unusual warm conditions that have persisted in the waters off Alaska and the West Coast now appear to be diminishing, said the climatologist who named the water mass the “Blob.”
