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. "

Deadly storm floods NYC, brings trees down in Philadelphia

A deadly storm flooded New York City, brought barges ashore in New Jersey, and sent a tree crashing onto a car in Philadelphia.

By Jesse Ferrell, AccuWeather meteorologist and senior weather editor

Published Oct 31, 2025 11:58 AM EDT | Updated Oct 31, 2025 11:58 AM EDT

" A powerful storm caused heavy rain in the Northeast on Thursday evening, flooding roads and subways in New York City, and sending two barges ashore in New Jersey. Two people perished in flooded New York City basements, according to ABC7.

In Philadelphia earlier in the day, a tree fell onto a moving car during heavy rain, killing the driver. High winds caused power outages, with approximately 15,000 customers in both New York and New Jersey without power during the storm's peak.

"The storm, which drew in additional moisture from Hurricane Melissa, featured rainfall rates of 1 inch per hour," AccuWeather Lead Hurricane Expert Alex DaSilva said. The high rain rates, along with clogged storm drains from fall leaves, led to the New York City flooding.

The heavy rain broke daily rainfall records across the region, including Central Park, LaGuardia Airport, Newark, Baltimore, and Williamsport, Pennsylvania."

Literally, when it does rain, it pours!

Warming atmosphere fueling heavier U.S. rainfall and rising flood risk, AccuWeather analysis shows

A new AccuWeather study of more than 60 years of rainfall records shows U.S. precipitation totals are flat, but heavy downpours and hourly extremes are increasing, raising the risk of flooding, damage, and economic losses.

By Monica Danielle, Sep 19, 2025

"It’s not raining more across the United States, but when it rains, it’s falling harder, faster and in more extreme bursts. That’s the finding of a new AccuWeather analysis of more than 60 years of weather records, which reveals a striking shift: National rainfall totals remain statistically flat, yet the number of heavy downpours and hours with extreme rainfall have increased sharply.

"These changes are fueling greater flood risk, straining infrastructure and threatening communities nationwide. "

They also specifically list regions near mountain ranges as safe carbon storage sites.

With permafrost and glacier melt & heavy downpours followed by huge temperature drops prising open rock fissures?

Uhm, I do realize geologists were among the authors 😁 I'm not saying they're wrong, how could I, I'm expert in nothing!
But I am really worried.
And perhaps, researchers can pick up on these worries and address them in future communications🖖🏽

Very good documentary about extreme weather in a weirding climate
https://www.youtube.com/watch?v=X6VCTfzl1DU
Rockström, Knutti, Swain and Erik Fischer explain weather phenomena like Lytton's 50°C in June 2021 and Valencia's 800mm rain October last year.
These explanations are very welcome as understanding them reduces my fear.

Then they stress the necessary adaptation and illustrate with a few examples how the human individual and collective mind so far has largely shrugged at communicated risks "It won't happen here."

This reminds me of Brunner et al 2025 who compared commonly low-ish resolution climate models like CMIP6 with high resolution climate models and their respective number of extreme events by 2049.

Municipalities do not yet know what's physically possible or physically plausible at their specific location.

I can imagine cases where making adaptation plans today without such Brunner-like high-resolution projections, the information base is just insufficient and the money spent on new bridges, new asphalt, new train tracks, or on flood mitigation later turns out to be mis-spent.

Okay, I mean, then it'll just get done again, because money is merely an idea, not a physical law. True, true...🤔
Yeah, right. It wouldn't matter much.

Making adaptation plans now also has lots advantages aside from planning actual hardware updates or swaps.
Once the clerks' brains shift gear toward adaptation, they'll get other ideas around climate weirding as well which will be beneficial for the community too.

#CapeVerde floods kill at least eight people

By Reuters
August 12, 2025

PRAIA, Aug 12 (Reuters) - "At least eight people were killed after flooding on Cape Verde's #SaoVicenteIsland overwhelmed emergency services and cut key roads, a regional civil protection councillor said on Tuesday.

"On Monday morning torrential rains lashed the northern island in the Atlantic archipelago located off #WestAfrica swamping roads and sweeping away vehicles and people.

"Municipal councillor Jose Carlos da Luz told a state broadcaster seven people had died in floods and one person was electrocuted, adding that three others were still missing.

"In a report on Monday, the International Federation of Red Cross and Red Crescent Societies put the death toll at nine and said 1,500 people had been displaced on Sao Vicente.

"Sao Vicente usually records 116 mm of rain in a year, according to Cape Verde's meteorology institute. But early on Monday 193 mm fell in just five hours, according to Ester Brito, an executive at the institute.

" 'It is a rare situation because what was recorded is above our 30-year climatological average,' she told Reuters, adding that in just two hours more rain fell than the island typically receives annually.

"The U.S. National Hurricane Center said on Monday that #TropicalStormErin was located about 280 miles (455 km) west-northwest of #CapeVerde and packing maximum sustained winds of 45 miles per hour (75 kph).

"Interior Minister Paulo Rocha said on Monday that floodwaters disrupted transport across #SaoVicente and severed the main road to Cesaria Evora International Airport, though the facility remained operational. #Rockfalls also blocked traffic.

" 'It was a difficult night marked by panic and despair,' Rocha told public radio, adding that first responders were inundated with distress calls.

"Rescue and cleanup operations were ongoing, but Rocha said authorities were mobilising resources that would allow the island to quickly return to normal life."

Officials issue highest-possible weather alert amid record-breaking #downpour: 'Black rainstorm warning'

Timothy McGill
Wed, August 6, 2025

"Torrential rain fell on Hong Kong recently, breaking a long-held record and disrupting life in one of the most densely populated urban centers in the world.

"The 'black rainstorm warning,' issued by the Hong Kong Observatory, represents the most severe level of rainstorm alert in #HongKong. It's triggered when torrential rain is causing or likely to cause serious #flooding and major #disruptions.

"In early August, the #HKO issued this dire warning not once, but four times in only eight days, setting a new benchmark for the most times the city's highest weather alert has been issued in a single year, according to China's state news agency Xinhua, per Reuters."

"The new study has shown that a large contrast in #soil moisture levels over a range of hundreds of kilometers results in atmospheric changes that increase rainfall area and amount in several megastorm hotspots globally. This increase ranges from 10% to 30% depending on the region and size of the storm."

More rain forecast after #StormBert hits UK

by David Mercer, Ian Aikman & BBC Weather
November 25, 2024

"More rain is due to fall in the coming hours and into Wednesday in southern England and south Wales, where flooding and high winds from Storm Bert have caused major disruption to homes, roads and rail networks.

"At least five people have died in the storm that struck much of the UK over the weekend and prompted criticism about a lack of preparation and insufficient warnings.

"The severe flood warning for the River Nene in Northamptonshire remains in force with a "danger to life and risk of significant disruption", as a holiday park has been submerged for the third time this year.

"Environment Secretary Steve Reed said more flooding was likely this week but it should be 'less severe' than on Sunday."

#Málaga evacuates thousands as #Spain issues more #FloodAlerts

by Nick Beake and Thomas Mackintosh

"Thousands of people have been evacuated from their homes in the #CostaDelSol region of southern Spain as #ExtremeRain and #flooding drenches the area.

"National weather office Aemet has placed both Malaga and the northeastern #Catalonia region on the highest alert for strong rain expected to last until Friday.

"The Malaga area, including the tourist resorts of Marbella, Velez and Estepona, is expected to take the brunt of the extreme weather phenomenon known as a '#Dana'.

"Parts of the eastern Valencia area have also been placed on the highest alert, weeks after the area was devastated by flash floods that killed more than 220 people.

"Several other regions in Spain remain braced for more heavy showers and low temperatures.

"Up to 180mm of rain could fall in #Catalonia in north-eastern Spain in just 12 hours, accompanied by thunderstorms along the coast near Tarragona, forecasters say.

"Schools in the entire southern province of Málaga have been closed while many supermarkets have kept shutters down.

"Footage circulating on social media showed the city's normally busy areas deserted as water flooded the streets.

"Around 3,000 people living in close proximity to the #Guadalhorce River have been told to leave their homes, the Regional Government of #Andalusia has said."
