California storm death toll increases to 5 as rain pummels Bay Area

Firefighters prepare to transport a patient by ambulance at the scene of a car stuck in flooding as a powerful storm moves across Southern California on February 17, 2017 in Sun Valley, California.
The death toll in the recent powerful California rainstorms rose to five as the weather system moved to pummel the northern portion of the state.

In Thousands Oaks, rescuers discovered the body of a man in his 20s who was swept away by floodwaters, the Ventura County Sheriff's Office said Saturday. On Friday, one person was found dead in Victorville in a flooded vehicle, a 55-year-old man was electrocuted in Sherman Oaks when a power line fell and two people died after a traffic accident in San Diego because of water on Interstate 15.

Meteorologists have called the storm "bombogenesis," an intense extra-tropical cyclonic low-pressure area, or "a weather bomb." They say the system is one of the strongest in years.

The storm flooded roadways in Los Angles and San Diego as power remained out and cars were underwater. At least 8 inches of rain fell on roads in San Diego.

On Friday, two cars plunged into a massive sinkhole in the Studio City neighborhood of Los Angeles.

Sun Valley, California. February 17, 2017.
At least two people have been killed - one drowned and another electrocuted - in a heavy storm that hit southern California, uprooting trees and sweeping vehicles away. Voluntary evacuations were called, while some highways were closed and numerous flights delayed or cancelled.

Two cars were swept away by floodwaters in Victorville, where police discovered one person dead in a submerged car, but were able to rescue another person in a separate car.

Los Angeles Fire Department responded to a man in Sherman Oaks who came in contact with downed power lines. The man was found in critical condition and was rushed to the hospital, where he was pronounced dead.

Two vehicles were reported to have fallen into a sinkhole in Studio City shortly after 8:30pm local time.

Fire and rescue crews are on scene.

Heavy rain, flooding as ex- Cyclone Dineo sweeps over South Africa

As the tropical ex-cyclone Dineo dissipates over SA, heavy rainfall has hit the north-eastern parts of the country.

Flooding has occurred following heavy rainfall late on Thursday afternoon, 16 February in the Free State capital of Bloemfontein, as some cars appeared to be floating.

To the north-eastern side of Bloem, the expected areas over Limpopo also received heavy rain. In the Kruger National Park, specifically, gravel roads have been closed and select remote camps evacuated in the wake of the rains.

KwaZulu-Natal, on the other hand, where disaster management teams have been on standby since Wednesday, was not hit as hard by the effect of Dineo.

In Mozambique, Dineo has displaced thousands of people, while seven fatalities have already been reported, the country's government disaster centre said on Thursday. Heavy rains and fierce winds have destroyed about 20 000 homes, they say.

Not just Oroville: Record rain is straining California's whole flood control network

© California Department of Water Resources
This image shows conditions at Lake Oroville and other Northern California reservoirs as of midnight February 15, 2017.
The frantic effort over the last few days to lower water levels at Oroville Dam after the structure's two spillways became damaged is part of a larger drama playing out as California rapidly shifts from extreme drought to intense deluges.

Large swaths of the region are on track to experience their wettest winter on record, with many areas having already surpassed their average precipitation for an entire year.

And all that water is putting new strains on the network of dams, rivers, levees and other waterways that are essential to preventing massive flooding during wet years like this one.

The biggest danger zone lies in the Central Valley at the base of the Sierra Nevada, whose tall peaks can wring the skies of huge amounts of rain and snow. The area is essentially one giant floodplain that would be easily transformed into an inland sea without man-made flood control. At 400 miles long and 40 miles wide, it has only a tiny bottleneck from which to drain — a one-mile opening at the Carquinez Strait at San Pablo Bay — before water heads into the San Francisco Bay.

California's Oroville Dam update: Spillway releases curbed, even as 'atmospheric river' looms

Oroville Dam Spillway
The water level at Lake Oroville continues to drop as state officials press on with the effort to drain the reservoir in light of a forecast calling for rain through Monday. Despite forecasts showing another "atmospheric river" poised to strike the region early next week, engineers began dialing back the water releases from Oroville Dam's main spillway Thursday in an effort to eventually restart the dam's shuttered hydroelectric plant. When operational, the plant could release additional water from Lake Oroville.

After pounding the damaged spillway with releases of 100,000 cubic feet per second since Sunday evening, the state Department of Water Resources dialed back the releases to 94,000 by late Thursday morning. DWR's website indicated releases would fall to 80,000 cfs by 3 p.m.

Even with the curtailed releases, the water level at troubled Lake Oroville continued to decline. The reservoir was falling by about 5 feet every 12 hours and was down to 867.5 feet just before noon, or nearly 34 feet below the top of the dam. Federal flood regulations say the lake should be at no more than 850 feet this time of year.


Projections of rainfall will overtop emergency spillway by 13 feet at California's Oroville Dam

Oroville Dam
With five overlapping weather forecast rainfall models, a full 3-5 inches of precipitation will fall in the drainage basin of the Oroville Dam, which will raise water levels faster that the damaged spillway can out flow over topping the emergency spillway by 13 feet. The last over top was 2-2.5 feet. Are you ready for the effects if the spillway ruptures as the water will damage natural gas pipelines, food deliveries and scour away roadways?

Evacuations in the south of France as rivers overflow

Flood in France
Heavy rain, up to 200 mm in some areas, caused flooding in parts of the Occitanie Region in southern France yesterday, 14 February.

Météo-France issued an orange level alert for flooding rain for the Aude, Hérault and Tarn departments on 14 February. Levels of the Aude River increased dramatically, causing the river to overflow in several areas during the afternoon of 14 February.

Local media report that around 150 people were evacuated and several houses flooded in Aude department. Flooded areas include Saint-Marcel, Marcorignan, Coursan, Conques-sur-Orbiel Cuxac, Sallèles-d'Aude and Peyriac-Minervois. River levels have since started to fall.

Update: "ROCK SHOT" at Oroville Dam: Repair before more rain overtops spillway again

Oroville Dam
UPDATE Assessment of ROCK SHOT Success as 3-6 Inches of Rain Blanket California. With less than a day left before new storms roll over California dumping 3-6 inches of new rainfall, which will over top the Oroville Emergency Spillway again. They are now dropping bags of rocks in the areas where the dam will collapse, I call it the "ROCK SHOT" which reminds me of the "Junk Shot" in the BP Oil Spill.

GOES WEST rainfall forecast maps as well. Once you leave your homes you will not be allowed to return for weeks if at all until spring. Good Luck.

Los Angeles area braces for what could be biggest storm of the season; flooding, mudslides possible

A rainstorm is expected to hit Southern California by Friday. A flash flood watch was issued for burn areas in Los Angeles and Ventura counties.
A powerful new storm is expected to arrive in Southern California on Friday, and it could provide a walloping, with possible flash flooding, mudslides and rock slides.

"The Friday storm in particular could in fact become the strongest of the season in the Los Angeles region," said UCLA climate scientist Daniel Swain.

A slow-moving storm is expected to debut in the Southland with some light rain Thursday night or Friday morning, but is expected to dump large amounts of rain in a short time frame during its peak Friday afternoon and evening, said Ryan Kittell, a forecaster with the National Weather Service in Oxnard.

Rainfall totals for the Los Angeles metropolitan area are predicted to be between 2 to 4 inches, with 6 to 8 inches expected in the mountains and foothills, he said.
