Disastrous' flood warning in California as another storm hits

'Disastrous' flood warning in California as
another storm hits

January 14 2023, by Huw GRIFFITH

Farm workers dig an irrigation canal around a field of strawberries as the Salinas
River begins to overflow its banks on January 13, 2023 in California.

Disastrous flooding could hit parts of California this weekend,
forecasters warned Friday, as the eighth storm in succession barreled in

1/7

over land already too waterlogged to soak up any more rain.

The most populous US state has been pummeled by near-record
downpours over a very wet three weeks, which have already caused
flooding, landslides and widespread power outages.

At least 19 people are known to have died as communities struggle to
cope with the constant deluge.

On Friday yet another system moved in, with forecasters warning the
Monterey Peninsula could be cut off and the whole city of
Salinas—home to 160,000 people—flooded.

"The entire lower Salinas Valley will have disastrous flooding," the
National Weather Service said.

"The entire city of Salinas is in danger of flooding. Most of Castroville
will flood. All roads near the Salinas River will be flooded and
impassable. 90,000 acres or more of agricultural land in the Salinas
Valley will have disastrous flooding.

"Many roads, homes and agricultural land areas in the Salinas Valley will
have major flood damage."

The Salinas River, already swollen by weeks of torrential rain, was
expected to peak some time Friday, breaching its banks in a flood that
could last until Sunday.

Floodwater are seen as the Salinas River overflows its banks on January 13, 2023
in California.

Kelley O'Connell said the bursting of a levee near her home had worried
her.

"If they release water from the dams or we get more rain, we're just a
field away," she told the San Francisco Chronicle as she collected
sandbags.

Evacuation orders and warnings were widespread, with forecasters
saying major roads could become impassable—including highways that
link the Monterey Peninsula with the rest of the county.

"Residents both on the peninsula and in the Salinas area should expect to
be cut off for two to three days," Monterey County officials said earlier
this week.

Monterey County Sheriff Tina Nieto told reporters Thursday that
floodwater could strand people.

"This is a slow-moving event" and not all places will be impacted at
once, she said.

"The river crests at different times."

Resident John Guru said he was taking no chances, with four days'
supplies at home and two days' worth in his car in case he is caught out
on the road.

"I'm not sure how bad it's going to be," he told the Monterey Herald.

"I will find a place if needed and do whatever it takes," he said, adding:
"This is crazy, I was not anticipating anything like this."

Snow

Workers have rushed out in between storms to clear up some of the mess
left behind, shoveling mud from roads even in the heart of Los Angeles.

Crews have cut up felled trees, and heavy machinery have been drafted
in to move rockslides.

Hundreds of thousands of homes and businesses have been left without
power at various times—sometimes repeatedly—as rickety
infrastructure has taken a battering.

And it's not over yet, forecasters say.

"The ongoing unsettled weather in the West associated with the active
Atmospheric River pattern unfortunately continues into this weekend
with another couple rounds of heavy precipitation forecast," the NWS
said.

5/7

This aerial view shows two cars siting in a large sinkhole that opened during a
day of relentless rain, January 10, 2023 in the Chatsworth neighborhood of Los
Angeles, California.

Over the mountains, that precipitation was falling as snow, with more
than three feet (a meter) expected in the Sierra Nevada range, making
travel dangerous or impossible, even as thousands of skiers and
snowboarders head for fresh powder over the Martin Luther King, Jr
Day holiday weekend.

Among those who have died in the last three weeks were drivers who
were found in submerged cars, people struck by falling trees, a husband

and wife killed in a rockfall, and people whose bodies were discovered
                                   in floodwaters.

                                   Winter storms are not unusual in California, where most of the annual
                                   rain comes in a fairly concentrated period.

                                   But global warming, driven by the industrial era's unchecked use of
                                   fossil fuels, is supercharging storms, making them wetter and wilder.

                                   At the same time, the western United States is aridifying, with much of
                                   the region in its 23rd year of drought.

                                   Hydrologists say the recent rains are helping—California has received an
                                   average of almost nine inches (23 centimeters) of rain since late
                                   December—but are not a fix.

                                   "A few weeks of storms is not enough in this drought for California, but
                                   it certainly is nice. It's certainly making a good dent," Jay Lund, director
                                   of University of California, Davis, told the Chronicle.
