Deadly #Floods Due to #Levee Failures Reflect Need for #Infrastructure Investment
Levees were never designed to handle extreme weather that is now more common due to climate change.
By Farshid Vahedifard, December 29, 2025
"In recent weeks, powerful #AtmosphericRiver storms have swept across #Washington, #Oregon and #California, unloading enormous amounts of rain. As rivers surged, they overtopped or breached multiple levees – those long, often unnoticed barriers holding #floodwaters back from homes and towns.
"Most of the time, levees don’t demand attention. They quietly do their job, year after year. But when storms intensify, levees suddenly matter in a very personal way. They can determine whether a neighborhood stays dry or ends up underwater.
"The damage in the West reflects a nationwide problem that has been building for decades. Across the U.S., levees are getting older while weather is getting more extreme. Many of these structures were never designed for the enormous responsibility they now carry.
"As a civil engineer at Tufts University, I study water infrastructure, including the vulnerability of levees and strategies for making them more resilient. My research also shows that when levees fail, the consequences don’t fall evenly on the population."

2nd #AtmosphericRiver to flood #California with firehose of rain into Christmas
#HeavyRain and #flooding problems experienced in the #Northwest in recent weeks from atmospheric rivers will shift farther south into California through Christmas Day with major travel disruptions and safety concerns.
By Alex Sosnowski, AccuWeather senior meteorologist
Published Dec 21, 2025
"Two main atmospheric rivers will force copious amounts of #Pacific moisture into #California this week. Heavy rain with incidents of flooding, washouts and mudslides will expand and shift from north to south over the state, leading to travel disruptions at the very least and posing some risk to lives and property in extreme cases. The #SierraNevada will receive many feet of snow as freezing levels lower through the week and the region is affected by both atmospheric rivers.
"The storms are hitting at a busy time of the year, with many traveling short and long distances, running errands and planning outdoor activities.
"The first atmospheric river was already in progress and will continue to focus on Northern to Central California into Wednesday. A second atmospheric river is forecast to develop and concentrate on Central and Southern California from Tuesday night through Christmas Day. But even beyond Christmas, lingering moisture will lead to additional rounds of showers and mountain snow, according to AccuWeather.
"Through Wednesday, much of the #Sacramento Valley and the #SanFrancisco Bay region will receive 2-4 inches of rain with locally higher amounts. The anticipated rainfall for San Francisco in the stormy pattern into next weekend will bring from one to two times the historical average for December.
"On the west- and southwest-facing mountainsides of the Coast Ranges and the Sierra Nevada, 4-12 inches of rain will pour down with an AccuWeather Local StormMax™ of 20 inches.
"At times, multiple inches of rain can fall in a matter of hours, overwhelming storm drains and causing small streams and short rivers to quickly overflow their banks. As the ground becomes saturated, the risk of debris flows, road washouts and hillside collapses will increase substantially.
"From Tuesday night to early Friday, the second atmospheric river will spray rain of varying intensity throughout Central and Southern California.
"A general 4-6 inches of rain is forecast to fall on the Los Angeles basin. Downtown, L.A. had seven times its historical average monthly rainfall for November with 5.53 inches. While no rain has fallen so far in L.A. this month, from two to three times December's average rainfall of 2.48 inches may occur with the stormy pattern from Tuesday to Saturday.
"On the southwest-facing hillsides of the Transverse Ranges, 6-12 inches will pour down with an AccuWeather Local StormMax™ of 16 inches. Even in many desert areas of Southeastern California, between 0.25 of an inch to 1 inch of rain is expected to fall.
"Just as with the first atmospheric river up north, rain will be drenching, leading to rapid urban flooding and flooding of small streams and short-run rivers, along with mudslides, washouts and the potential for hillside slides in Southern California. "

#California Issued Warning Over ‘Onslaught’ of #AtmosphericRivers
By Amanda Greenwood, Dec 17, 2025
"Following last week’s atmospheric rivers—which triggered flooding in the #Cascades and #WashingtonState—the #WestCoast is facing another series of storms, now shifting south. These systems are expected to bring heavy rain and mountain snow to #Oregon and #NorthernCalifornia from Wednesday into the weekend and next week, according to senior meteorologists at The Weather Channel.
"In summary, these meteorologists have forecast that Wednesday could bring heavy rain and high winds to the northwest and far northern parts of California, lessening to showers on Wednesday afternoon.
"Another atmospheric river will then hit #Oregon, Washington, #Idaho, and #Montana on Thursday, bringing snow and rain. By Friday, the system is expected to move into southern Oregon and northern California, particularly affecting areas north of the Bay Area. Over the weekend, there is a concern that northern California will be badly affected by rainfall on Sunday, with locally heavy rain forecast to return to Oregon and Washington.
"They've predicted that the heaviest rainfall is expected to fall over the weekend, in western Oregon and northern California, particularly #Siskiyou and coastal ranges along the California coast, where up to 5 inches of rain is forecast. This is likely to cause #FlashFlooding and possibly even #landslides—especially in areas that have recently experienced #wildfires.
"Already flooded areas in Washington—particularly the Skagit, Snohomish, Green, White, Cowlitz, Chehalis, and Yakima Rivers—could experience secondary crests, a later rise in river levels, from the additional rainfall. Although levels aren’t expected to be as high as last week, it could cause 'major flooding,' especially along the #SkagitRiver."

A few weeks ago... Expect #BombCyclones and #AtmosphericRivers to become a common and unpredictable occurrence with #ClimateChange!
Europe's weekend #BombCyclone to rival B.C.’s intense storms
Dennis Mersereau
Fri, November 22, 2024"Canada has been no stranger to weather bombs this season. British Columbia is in the midst of its second bomb cyclone in one week—another intense storm hitting the same areas affected by hundreds of thousands of power outages just days earlier.
"While B.C.’s second storm won’t grow as strong as the first, another storm out in the Atlantic Ocean could rival that first storm’s monstrous strength.
"Storm Bert is brewing in the northern Atlantic Ocean, and it’s got its eyes set on the British Isles heading into this weekend.
"The storm’s minimum central pressure is expected to drop a whopping 40-50+ mb in just 24 hours. This swift strengthening would more than double the criteria needed for bombogenesis, the process of rapid intensification that creates a bomb cyclone."

Of course, #TFG's comments are unfounded and pie in the sky.
And, OFC he doesn't know it, but in essence, he's actially right about the potential of reclaiming unused #rainfalls, in particular using #AtmosphericRivers weather conditions on the #WestCoast.
There are already some projects of limited scope, apart from #LA: -
#SolutionsForClimateChange: #Agrivoltaics and #WaruWaru
The solutions for a big part of the planet have been with us since 1977 and 300 BCE: Agrivoltaics and Waru Waru, also called #sucacollos.
This is true in regions experiencing extreme rainfalls due to #AtmosphericRivers, like the US West Coast, or monsoon regions in #Asia vor parts oft the #US. -
Finally my paper looking at #AtmosphericRivers is out!
"How River-like ARE Atmospheric Rivers?”
VERY-- they take moisture from 1000's km and 10deg equatorward than your average storm.
#NASA #CYGNSS - GPS array that looks at how choppy the ocean surface is to determine surface wind speed and heat fluxes compares well w simulations from the #NASAGISS climate model w include a tracer suite that identifies where moisture in the atmosphere originally evaporated from.

The top 10 most impactful #weather events of 2023
From powerful #hurricanes and #tornadoes to drought-busting storms and the deadliest #wildfire in the US in a century, here is a look back at the most unforgettable weather events of 2023.
By Monica Danielle, AccuWeather senior producer
Published Dec 26, 2023
1. Record-breaking January tornado outbreak
In a month typically clocking inches of snow, there were a whopping 168 tornadoes reported over two outbreaks, more than triple the historical average for January, setting a new record for the month.
An outbreak on January 12 produced 70 tornado reports across seven states. This date included two EF3 tornadoes that resulted in at least 9 deaths and 34 injuries across #Alabama and #Georgia. An EF2 tornado also caused devastation in the historic city of #SelmaAlabama, about 40 miles west of Montgomery.
2. Violent EF4 tornado rips through #Mississippi, killing 17
On March 24, two dozen twisters touched down across the Southeast, including the deadliest and one of the year’s most violent tornadoes. The EF4 tornado ripped through #Rolling ForkMississippi, and claimed the lives of 17 people, including a couple killed by a large semi-truck that was tossed into their home.
3. The most notable tornado outbreak of the year
The most notable tornado outbreak of 2023 was the deadly and now historic outbreak that impacted large portions of the Midwest, South, and East U.S. on March 31 and April 1. The year's second and final EF4 tornado was one of 122 twisters reported across multiple states. AccuWeather's own storm tracker and meteorologist, Tony Laubach, captured incredible footage of one of the strongest tornadoes of the year when he intercepted the twister in southeast #Iowa near the city of #Ottumwa.
4. Drought-busting #AtmosphericRivers unload record-breaking #snow
Coming into 2023, drought was a major concern for #California and other parts of the West. "This is a #megadrought," California Governor Gavin Newsom said. "Some scientists argue it's the most significant in 1200 years of human history." But it wouldn't be long until the #drought was wiped out completely.
5. Smoke from #Canada's worst-ever wildfire season blankets US cities
Canada experienced its worst wildfire season on record, obliterating all other years in terms of area burned. Over the course of the fire season, flames scorched an estimated 18.4 million hectares—an area roughly the size of North Dakota. According to NASA, on average, just 2.5 million hectares burn in Canada each year.
6. Deadliest US wildfire in more than a century sweeps through #Maui, #Hawaii
The wildfire that ignited in Maui on August 8 was the deadliest in the U.S. in more than a century, killing at least 106 people and all but incinerating #Lahaina, destroying every building in the town of 13,000.
7. #HurricaneIdalia slams #Florida's Nature Coast
The above-normal 2023 Atlantic hurricane season was characterized by record-warm #AtlanticSeaSurfaceTemperatures and a strong #ElNiño. A total of 20 storms were named in 2023, along with a tropical depression and an unnamed subtropical storm. This ranks fourth for the most-named storms in a year since 1950 and the most on record during an El Niño-influenced season. Seven storms were hurricanes, three intensifying to major #hurricanes.
8. #HurricaneLee stirs up rough surf, and dangerous rip currents along East Coast
Before making landfall in far western #NovaScotia, Hurricane Lee caused dangerous surf and rip currents along the Atlantic Coast of the United States. Lee claimed two victims, a 51-year-old man who was killed by a falling tree branch in #Maine and a teenager who drowned off the coast of Florida amid rough seas churned up by the hurricane. The monstrous storm cut power to more than 280,000 electric customers across Maine, Nova Scotia and New Brunswick as it roared ashore.
9. The hottest year in recorded history
Six record-breaking months and two seasons – summer and autumn – were recorded in 2023, making it the hottest year ever recorded.
10. El Niño nears historic strength
The global weather phenomenon El Niño, in which surface waters are abnormally warm in the eastern tropical Pacific, was a major player in many of the top weather events in 2023. The major shift to El Niño following three years of La Niña, could evolve into one of the strongest El Niño events observed over the past 75 years, new data shows.

This ranks fourth for the most-named storms in a year since 1950 and the most on record during an El Niño-influenced season. Seven storms were hurricanes, three intensifying to major #hurricanes.
8. #HurricaneLee stirs up rough surf, and dangerous rip currents along East Coast
Before making landfall in far western #NovaScotia, Hurricane Lee caused dangerous surf and rip currents along the Atlantic Coast of the United States. Lee claimed two victims, a 51-year-old man who was killed by a falling tree branch in #Maine and a teenager who drowned off the coast of Florida amid rough seas churned up by the hurricane. The monstrous storm cut power to more than 280,000 electric customers across Maine, Nova Scotia and New Brunswick as it roared ashore.
9. The hottest year in recorded history
Six record-breaking months and two seasons – summer and autumn – were recorded in 2023, making it the hottest year ever recorded.
10. El Niño nears historic strength
The global weather phenomenon El Niño, in which surface waters are abnormally warm in the eastern tropical Pacific, was a major player in many of the top weather events in 2023. The major shift to El Niño following three years of La Niña, could evolve into one of the strongest El Niño events observed over the past 75 years, new data shows.

The Winds of Change: Foehn Drive Intense Melt
https://eos.org/articles/the-winds-of-change-foehn-drive-intense-meltIncreasing extreme melt in northeast Greenland linked to #foehn winds and atmospheric rivers https://www.nature.com/articles/s41467-023-37434-8
"#AtmosphericRivers on the northwestern Greenland #IceSheet are driving dry winds across northeastern #Greenland, forcing extreme short-term #melt... as atmospheric moisture rises because of #GlobalWarming, an increase in atmospheric rivers is expected"

Summary: There may be fewer atmospheric rivers because of climate change, but the ones that occur will be extreme.
NASA: #ClimateChange may lead to bigger #AtmosphericRivers
By Esprit Smith,
NASA's Jet Propulsion Laboratory
May 24, 2018"A new NASA-led study shows that #ClimateChange is likely to intensify #ExtremeWeather events known as atmospheric rivers across most of the globe by the end of this century, while slightly reducing their number.
"The new study projects atmospheric rivers will be significantly longer and wider than the ones we observe today, leading to more frequent atmospheric river conditions in affected areas.
"The results project that in a scenario where greenhouse gas emissions continue at the current rate, there will be about 10 percent fewer atmospheric rivers globally by the end of the 21st century,' said the study's lead author, Duane Waliser, of NASA's Jet Propulsion Laboratory in Pasadena, California. 'However, because the findings project that the atmospheric rivers will be, on average, about 25 percent wider and longer, the global frequency of atmospheric river conditions -- like #HeavyRain and #StrongWinds -- will actually increase by about 50 percent.'
"The results also show that the frequency of the most intense atmospheric river storms is projected to nearly double.
"Atmospheric rivers are long, narrow jets of air that carry huge amounts of water vapor from the tropics to Earth's continents and polar regions. These 'rivers in the sky' typically range from 250 to 375 miles (400 to 600 kilometers) wide and carry as much water -- in the form of water vapor -- as about 25 Mississippi Rivers. When an atmospheric river makes landfall, particularly against mountainous terrain (such as the Sierra Nevada and the Andes), it releases much of that water vapor in the form of rain or snow.
"These storm systems are common -- on average, there are about 11 present on Earth at any time. In many areas of the globe, they bring much-needed precipitation and are an important contribution to annual freshwater supplies. However, stronger atmospheric rivers -- especially those that stall at landfall or that produce rain on top of snowpack -- can cause disastrous #flooding.
"Atmospheric rivers show up on satellite imagery, including in data from a series of actual atmospheric river storms that drenched the U.S. West Coast and caused severe flooding in early 2017."

Sorry to hear that.
However, #NovaScotia's new climate conditions sounds as if it would also need an agricultural revolution suggested by me earlier this year combining the #German #FraunhoferInstitut's new tech of #agrivoltaics with the ancient agricultural method of #WaruWaru from the #Andean #Altiplano, subject to #AtmosphericRivers.

@privateshufti this article is really wonderful, thank you so much for sharing. The need for and already occurring emergence of new vocabulary has already been a #ClimateDiary theme (#WinterDrought #AtmosphericRivers etc) but Anna Badkhen puts it so well
“Every day spells a new normal, requires our hearts to learn an endless vocabulary.” ❤️

⬆️ “Across #California, residents have been reeling from the effect of #extremeweather, with a large portion of the state now covered by a presidential emergency declaration. California has been hit with 11 #atmosphericrivers in a virtually nonstop series that has sparked #floods and #landslides, toppled trees, stranded mountain dwellers in historically deep snow and downed power lines, leaving thousands without electricity.” What’s it like in

A day after the big New Year's Eve storm. Off in the distance black cattle are standing in the snow next to a farmhouse. We already have so much snow and several more Atmospheric River storms are forecasted this week and into the future. It will take a while to dig out from all of this.
