Sudan declares 3-month state of emergency over deadly floods

Floods have killed 99 people and caused total and partial collapse of more than 100,000 homes, says local media.

...

The rates of floods and rain for this year exceeded the records set during the years 1946 and 1988, with expectations of continued rising indicators, minister Lena el-Sheikh added.

...

Sudan's rainy season begins in June and continues through to October, which means the country experiences floods and torrential rains annually.

The committee warned on Friday the country may face more rains, adding that the water level in the Blue Nile rose to a record 17.58 metres.

I think you live in north-west Florida Tor. There's flooding in Florida because of 'stalled' tropical storm Sally. Are you okay?

Quote
Significant coastal flooding has been affecting much of the Southeast and mid-Atlantic U.S. coast since September 15, during the high “king tide” period associated with the New Moon of September 17. The king tides have been exacerbated by big swells from Hurricane Teddy, high runoff from the heavy rains from Hurricane Sally the previous week, and powerful northeast winds associated with a strong area of high-pressure positioned over New England.

It seems a hurricane doesn't have to get anywhere near the Carolinas to flood their coast these days.

I live right above the 'armpit' of Florida, called the "Big Bend" when tourists are listening.  I had 125 mm (5") of rain in 36 hours plus several 10-20 mm days before and after, due to Sally.  No flooding in my neck of the woods, but our neighborhood dirt/gravel road did get a bit rutted.  (We've certainly see worse.)  My papaya tree fell down, though, top heavy with fruit and sodden soil.  Its leaves seem to be perfectly happy, but most of the fruit broke off - about half the roots are still in the ground.

Thanks for your concern.  Pensacola, which did get some rain, is about 325 km (200 miles) to my west.

Kenya: Red Flag as Swelling Rift Valley Lakes Wreak Havoc
28 September
https://allafrica.com/stories/202009290072.html

Quote
The lake waters are extending at a high speed, worrying residents and scientists, who seem not to have sufficient explanation as rains have not fallen in huge volumes over the past few months.

Lakes Nakuru, Naivasha, Baringo and Bogoria have expanded to levels not seen in 75 years, with the Water Resources Authority, (WRA) revealing that the phenomenon has affected the quality of water.

WRA attributes the rising water levels to tectonic activities and the effects of climate change on rainfall patterns. WRA says water levels in all the five lakes in the Rift Valley have risen to the highest recorded levels in recent years.

[...]

When the Nation visited the park on Sunday, KWS was racing against time to relocate animals among them zebras, rhinos, buffaloes, and gazelles, which are fighting for the limited space in the park.

Acacia trees that used to host baboons have been immersed in the waters, pushing the animals into neighbouring estates. Flamingos and pelicans that used to feed at the shores of the lake have fled.

The raging waters have also invaded KWS rangers' homes, forcing some to relocate to Nakuru town. In Lake Baringo, more than 15 schools bordering the lake may need to be relocated after water levels rose drastically, swallowing adjacent structures.

Havler-Barrett at the independent: Flood the poor, the rich got lawyers

"Water was discharged from the Peñitas dam following flooding caused by Hurricane Eta"

"President Andres Manuel Lopez Obrador said on Monday that he understood the decision would cause harm"

“They are Chontales [Indigenous Tabascans], the poorest, but we had to make a decision,”

"Meanwhile, Mexican social media has been alight with dramatic footage of a rescue of a dog"

Water from Murray-Darling Basin plan not being delivered to wetlands, Australian-first report finds

The majority of environmental water redirected from irrigators under the $13 billion Murray-Darling Basin Plan isn't being delivered to its intended wetland targets, with private land blocking the connections between rivers and floodplains, new research shows.

The research, published today, found less than a quarter of the nearly 200,000 hectares of floodplains targeted with environmental water controlled by the Federal Government between 2014 and 2019 has actually delivered an effective flood, leaving crucial ecosystems heading towards collapse.

Jamie Pittock, an expert in water management from the Australian National University, said the study was the first to look at what the Basin Plan sought to achieve for the environment and measure its progress, in totality.

"And sadly, that progress is lacking," Professor Pittock said.

Overall, only 2 per cent of all the wetlands throughout the Murray-Darling Basin that could be inundated with environmental water controlled by the Federal Government were actually watered each year, he said.

"This is a $13 billion reform program, and we think that the Australian public would expect a better rate of return than 2 per cent per year," he told the ABC.

...

But the new research shows those intentional environmental floods are being stopped, mostly by towns and private farms.

Since agreements haven't been reached with about 3,300 farmers to allow the flooding to pass through private property, the environmental water isn't able to reach the wetlands.

...

Professor Pittock and his co-authors examined commonwealth environmental flows in the five years to 2019.

Without agreements with private landholders, the CEWO could sometimes only create very small floods that wouldn't risk running across private property.

As a result, Professor Pittock said each watering event ended up inundating only the low-lying parts of the floodplain. But since some types of ecosystems — like black box eucalyptus forests — live higher on floodplains, some ecosystems were almost never benefiting from the environmental water.

"It's really only the easy-to-water billabongs and low-lying redgum forests that are getting watered, whereas other kinds of wetland ecosystems are being disadvantaged, like black box floodplain forests," Professor Pittock said.

"The risk is that the disadvantaged ecosystems will be significantly lost unless these programmes are improved," he said.

Colman at politico: mispriced mortgages

"Taxpayers are backing more than a trillion dollars in home mortgages, but the agencies buying them are neglecting to consider climate risks."

“It just has not reached that level of concern. And it never does, right?”

"political, scientific, technical and social complexities that have left the taxpayer-backed mortgage market suspended in time, unwilling or unable to prepare for the inevitability of property- and wealth-destroying climate change."

"Officials at the FHFA, which oversees Fannie Mae and Freddie Mac, maintain that taxpayers are protected by flood insurance requirements."

"Turning off the mortgage spigot in communities affected by climate change would disproportionately affect people of color, whose neighborhoods are more likely to be plagued by violent weather."

"a peculiar kind of stasis — a crisis that everyone sees coming but no one feels empowered to prevent, even as banks and investors grow far savvier about assessing climate risk."

"The mortgage giants appear to be taking fledgling steps ... issued a request for proposals to analyze climate exposure to homes that are outside the 100-year floodplain, and therefore do not require flood insurance coverage"

"some current and former federal housing officials who were interviewed by POLITICO said that they interpret the charters that formed Fannie Mae and Freddie Mac as preventing officials from deciding, on their own accord, to stop buying mortgages in areas at high climate risk ... Others who occupied the same positions said the exact opposite."

"any actions taken by the two mortgage giants would be highly disruptive in themselves: A refusal to buy mortgages on homes in certain areas would potentially choke off lending in those areas, driving down housing prices ... But failing to take preventative action in anticipation of climate changes risks a far greater downturn."

"Weighing those climate-fueled dynamics would take Fannie Mae and Freddie Mac into the political minefield of place-based pricing. The companies’ charters discourage such distinctions in order to create a national mortgage market. Maintaining a largely homogeneous market helps to combat redlining policies that have deprived predominantly Black neighborhoods of access to credit, while also ensuring that rural communities have the same access to credit as urban areas that have far more lenders. "

"In the early 1990s, Fannie Mae and Freddie Mac tried to raise the price of mortgages on properties in California neighborhoods with a high risk of earthquake damage, only to backtrack in the face of furious opposition"

" Fannie Mae and Freddie Mac already maintain some forms of risk-based pricing. The lenders charge banks higher rates — known as “guarantee fees” — when a borrower’s credit history signals a greater default risk."

"Making those decisions would put the mortgage giants in a position to write off whole communities ... many Black communities are situated in low-lying areas as a result of racist historical policies. "

“That we are rapidly growing places that are just right there in the bull's-eye of climate change just doesn’t make any sense.”

"The mortgage giants have already made an implicit decision to distort the market by not pricing climate risk ... They extend more financing to climate-vulnerable borrowers than the properties are worth. Thus they put taxpayer dollars and American lives in the crosshairs of extreme weather and storms. "

"Fannie Mae and Freddie Mac have no designated financial buffer for offsetting climate-related losses"

"This sets up the possibility that banks would deliberately sell off mortgages in areas with climate risks to Fannie Mae and Freddie Mac — which can’t refuse them, given the mandate to provide market liquidity — while keeping the sturdier loans on their own books."

"Banks such as Wells Fargo, Morgan Stanley, Citigroup and Bank of America acknowledged in response to questions from Sen. Elizabeth Warren (D-Mass.) that they are using new tools and services to gauge climate risk"

" if the bank ever becomes convinced of the inevitability of climate change in certain places, it could simply flip any loans in those places to Fannie Mae and Freddie Mac, which would be obligated to buy them. That means taxpayers would be guaranteeing the risk rather than private lenders."

“We don’t do that today … but that is certainly something I have contemplated.”

“Until those loans that are in zip codes that have flood risk trade at a discount to other loans, [Fannie Mae and Freddie Mac] won’t care ... But since there’s a guarantee to credit risk, [investors] don’t care.”

"The fear is that, if the properties are destroyed, Fannie Mae and Freddie Mac would indeed pay off the mortgages immediately. But that would deprive investors of the benefits of interest over the longer term."

"these assets have been priced irresponsibly"

"As Hurricane Harvey barreled down on Texas in 2017, securities that Fannie Mae and Freddie Mac sell to private investors in what’s known as a “credit risk transfer” went haywire, spiking 150 basis points — or 1.5 percent — amid fears that the storm would obliterate entire communities. When the credit risk transfer market settled after Harvey, the Association of Mortgage Investors, a trade group representing mortgage securities buyers, asked Fannie Mae and Freddie Mac to remove mortgages vulnerable to climate change from those offerings."

" unlike with most of the mortgage-backed securities that the mortgage giants sell, private buyers take the loss on credit risk transfers if mortgages default. The idea is to relieve taxpayers of the risk of having to cover for potential losses, putting it on private investors instead. But that solution can only work for so long, especially given the pressure investors have put on the mortgage giants to remove loans on properties at risk of climate change from those offerings"

"Fannie Mae and Freddie Mac took the loans out of the credit risk transfer pool, he said, letting climate-vulnerable mortgages pile up on their own books."

Haines is a small town in the South East of Alaska and is accustomed to receiving storms coming in off the N. Pacific. The area's infrastructure is designed with massive precipitation events in mind.
But, close to a foot of rain in a day has overwhelmed the place's capability.
Roads have collapsed, homes flooded or swept out to sea by a landslide.
People are still missing.

Mitigation fail.
Venice floods as weather catches city off-guard
Quote
Much of Venice was left under-water on Tuesday, as unexpectedly severe weather caused flooding in the city.

A new system of 78 flood gates, known as Mose, guard the entrance to the Venetian lagoon and were designed to protect the city from tides of up to 3 metres (10 ft), however, they require 48-hours notice to be activated.

We were warned about this Mediterranean cyclon days ahead, so I don't know why the Venetians did nothing. Not that this was unexpected, or anything...

I read the forecast was just below where it would be needed so they didn't activate the system. A promise to review guidelines was given.

They predicted 125 CM of rise but they got 138 CM. So the weather prediction was not accurate enough. I wonder how much margin they use though.

I dont know but given it take 24 hours to deploy I bet it is a major disruption to waterway traffic. Given all but foot traffic is waterway traffic I imagine people complain almost as much when it is deployed and not needed as when it is not deployed and needed.

In a blog post putting 500,000 American Covid-19 deaths into a population-influenced perspective, E-V.com posted a pair of charts that include the 1931 Chinese floods.

These 1931 floods rank 9th worst of 'compared events' when considering 'per year' deaths of the various events. (The American Covid-19 experience ranks 17.  The Armenian genocide, the 14th century bubonic plague in Europe and the Spanish conquest of the Incas rank 1, 2 and 3.)

Let us not forget the USAF bombing of the dikes in North Korea, possibly over 1.5 million civilians drowned.   It was mentioned in MacKinlay Kantor's (Andersonville Pulitzer prize) ghosted autobiography of Gen. LeMay.

Not only are these war-caused floods not know in the US, Wikipedia appears to be nearly silent on the matter.  For example, the words "dike," "flood" and "drown" don't appear in the Korean War article.  There is reference to the bombing of dams in May 1953, but it refers to potential starvation consequences (which were mitigated by international aid), not drowning.  With estimates of 1.5 to 3 million civilian (1.5 m military) casualties during that war, if a million people drowned, somebody should update the Wikipedia article with references.

In Wikipedia's Bombing of North Korea article, "flood" is referenced associated with bombing of dams, with thousands of acres of rice fields flooded and 43 km of a river valley "scooped clean".  Although people undoubtedly drowned, Wikipedia is mum on drowning deaths.

In Wikipedia's List of natural disasters by highest estimated death toll excluding epidemics and famines, the 1931 Chinese floods lead the list.  An 1887 flood in China comes second.

An act of war is not a natural disaster.
If bombing of the dam does not appear in wiki article add it. Even just mentioning it may encourage someone else to fill in the details.
