Storm Daniel was Greece’s worst storm in recorded history but for Libya it would trigger a disaster of unimaginable scale.
Sky’s Data and Forensics team looks at the warning signs that were missed and how human error exacerbated a natural disaster.
The storm began forming over the Ionian Sea on 4 September and after battering Bulgaria, Turkey and Greece it made its way south across the Mediterranean towards Africa.
Some warnings in Libya were issued but critics say more action could have been taken before the flash floods hit.
Weather warnings

Based on these warnings, a state of emergency was announced in the eastern regions.
But no mitigations were put in place and no evacuations were carried out, as the storm made landfall in the eastern city of Derna.
Footage verified by Sky News shows a torrent of water swelling the Wadi river, which runs from the mountains and through the city, in the early hours of Monday morning.
Residents were seen filming the water from the riverbank by the city’s al Sahaba Mosque. The flash floods and the collapse of the dams would later sweep away entire neighbourhoods and kill more than 11,000 people.
Old dams from 1970s
But it wasn’t just the weather that impacted the outcome of this disaster.
The World Meteorological Organisation (WMO) said Libya’s National Meteorological Centre “didn’t address the risk posed by the ageing dams” which burst.
The two dams located upstream around 5km apart were built in the 1970s.
A hydrological report published just last year warned that maintenance of the two structures was required to prevent catastrophic flooding.
But the deputy mayor of Derna has said neither dam had been maintained since 2002.
The report, in the Sebha University Journal of Pure and Applied Sciences, said the area has a “high potential for flood risk”, adding that dams of Wadi Derna basin needed “periodic maintenance” and that large floods could cause one of the dams to collapse making those in Derna vulnerable.
Before and after satellite images of one of the dams shows the extent of the damage after flash floods ripped through the structure.
Both the infrastructure and the politics at play have impacted this disaster.
Professor in Climate Risks & Resilience, University of Reading, Liz Stephens said: “There’s no such thing as a natural disaster.
“So there might be an extreme weather event, but it’s that interplay with the community, the governance and the people on the ground that leads to that risk.
“In this case, if the dams were not there, then we wouldn’t have seen large loss of life as a result of their collapse.”
Sky News will air a special programme – Libya floods: The city swept away – at midday on Saturday.
A curfew and no evacuation
Authorities have also been blamed for their initial response and handling of the disaster.
While critics say evacuations should have taken place to move residents of Derna to safer areas, the authorities instead told the population to hunker down.
On 10 September the mayor met with the security directorate of Derna, images posted on Facebook show.

The pair discussed a curfew and urged residents to stay in their homes.
They say the measure was put in place for citizens’ safety, but that announcement was met with anger and complaints at the time and afterwards in comments on the Facebook page.
The head of the WMO, secretary-general Petteri Taalas, added that evacuations should have been ordered and Libya’s government was “not functional”.
Had there been a weather service which could have issued warnings, emergency management authorities would have been able to carry out evacuations, he added.
For Libya, rescue operations are complicated by political fractures in a country which has been at war on-and-off with no strong central government since a NATO-backed uprising toppled Muammar Gaddafi in 2011.
But the deadly combination of a powerful storm, inadequate infrastructure and an unstable political environment has left the people of Libya victim to a disaster which might largely have been avoided.
Around 14 million people could die across the world over the next five years because of cuts to the US Agency for International Development (USAID), researchers have warned.
Children under five are expected to make up around a third (4.5 million) of the mortalities, according to a study published in The Lancet medical journal.
Estimates showed that “unless the abrupt funding cuts announced and implemented in the first half of 2025 are reversed, a staggering number of avoidable deaths could occur by 2030”.
“Beyond causing millions of avoidable deaths – particularly among the most vulnerable – these cuts risk reversing decades of progress in health and socioeconomic development in LMICs [low and middle-income countries],” the report said.

March: ‘We are going to lose children’: Fears over USAID cuts in Kenya
USAID programmes have prevented the deaths of more than 91 million people, around a third of them among children, the study suggests.
The agency’s work has been linked to a 65% fall in deaths from HIV/AIDS, or 25.5 million people.
Eight million deaths from malaria, more than half the total, around 11 million from diarrheal diseases and nearly five million from tuberculosis (TB), have also been prevented.
USAID has been vital in improving global health, “especially in LMICs, particularly African nations,” according to the report.

Queer HIV activist on Trump and Musk’s USAID cuts
Established in 1961, the agency was tasked with providing humanitarian assistance and helping economic growth in developing countries, especially those deemed strategic to Washington.
But the Trump administration has made little secret of its antipathy towards the agency, which became an early victim of cuts carried out by the Department of Government Efficiency (DOGE) – formerly led by Elon Musk – in what the US government said was part of a broader plan to remove wasteful spending.

What is USAID?
In March, US Secretary of State Marco Rubio said more than 80% of USAID schemes had been closed following a six-week review, leaving around 1,000 active.
The US is the world’s largest humanitarian aid donor, providing around $61bn (£44bn) in foreign assistance last year, according to government data, or at least 38% of the total, and USAID is the world’s leading donor for humanitarian and development aid, the report said.
Between 2017 and 2020, the agency responded to more than 240 natural disasters and crises worldwide – and in 2016 it sent food assistance to more than 53 million people across 47 countries.
The study assessed all-age and all-cause mortality rates in 133 countries and territories, including all those classified as low and middle-income, supported by USAID from 2001 to 2021.
Thailand’s prime minister has been suspended after a leaked phone call with a senior Cambodian politician caused outrage.
An ethics investigation into Paetongtarn Shinawatra is under way and she could end up being dismissed.
The country’s constitutional court took up a petition from 36 senators, who claimed dishonesty and a breach of ethical standards, and voted 7 to 2 to suspend her.

The prime minister’s call with Cambodia’s former leader, Hun Sen, sparked public protests after she tried to appease him and criticised a Thai army commander – a taboo move in a country where the military is extremely influential.
Ms Shinawatra was trying to defuse mounting tensions at the border – which in May resulted in the death of one Cambodian soldier.
Thousands of conservative, nationalist protesters held a demo in Bangkok on Saturday to urge her to step down.
Her party is clinging on to power after another group withdrew from their alliance a few weeks ago over the phone call. Calls for a no-confidence vote are likely.

Deputy prime minister Suriya Juangroongruangkit will take over temporarily while the court looks into the case.
The 38-year-old prime minister – Thailand‘s youngest ever leader – has 15 days to respond to the probe. She has apologised and said her approach in the call was a negotiating tactic.
The popularity of her government has slumped recently, with an opinion poll showing an approval rating of 9.2%, down from 30.9% in March.
Ms Shinawatra comes from a wealthy dynasty synonymous with Thai politics.
Her father Thaksin Shinawatra – a former Manchester City owner – and aunt Yingluck Shinawatra served as prime minister before her – in the early to mid 2000s – and their time in office also ended ignominiously amid corruption charges and military coups.
Israeli Prime Minister Benjamin Netanyahu will be meeting Donald Trump next Monday, according to US officials.
The visit on 7 July comes after Mr Trump suggested it was possible a ceasefire in Gaza could be reached within a week.
On Sunday, he wrote on social media: “MAKE THE DEAL IN GAZA. GET THE HOSTAGES BACK!!!”
At least 60 people killed across Gaza on Monday, in what turned out to be some of the heaviest attacks in weeks.

According to the Hamas-run health ministry, 56,500 people have been killed in the 20-month war.
The visit by Mr Netanyahu to Washington has not been formally announced and the officials who said it would be going ahead spoke on condition of anonymity.
An Israeli official in Washington also confirmed the meeting next Monday.

White House Press Secretary Karoline Leavitt said the administration was in constant communication with the Israeli government.
She said Mr Trump viewed ending the war in Gaza and returning remaining hostages held by Hamas as a top priority.
The war in Gaza broke out in retaliation for Hamas’ 7 October 2023 attacks on southern Israel that killed 1,200 people and saw a further 250 taken hostage.
An eight-week ceasefire was reached in the final days of Joe Biden’s US presidency, but Israel resumed the war in March after trying to get Hamas to accept new terms on next steps.
Talks between Israel and Hamas have stalled over whether the war should end as part of any ceasefire.
