Storm Daniel

wikipedia: “Storm Daniel, also known as Cyclone Daniel, was the deadliest and costliest Mediterranean tropical-like cyclone ever recorded as well as the deadliest cyclone worldwide since Cyclone Nargis in 2008. It was also the deadliest weather event of 2023 to date.^[4] Forming as a low-pressure system around 4 September 2023, the storm affected Greece, Bulgaria, and Turkey with extensive flooding. The storm then organized as a Mediterranean low and was designated as Storm Daniel. It soon acquired quasi-tropical characteristics and moved toward the coast of Libya, where it caused catastrophic flooding before degenerating into a remnant low. The storm was the result of an omega block, as a high-pressure zone became sandwiched between two zones of low pressure, with the isobars shaping like the Greek letter Ω.^[5][6]

In Greece, the storm was considered the worst in recorded history, with severe rainfall leading to flooding that caused more than two billion euros in damage. Libya was hit the hardest, with torrential rains causing two dams near the city of Derna to fail. This resulted in more than ten thousand deaths, with between 10,000 and 100,000 people missing, although exact figures varied by source. Libya's vulnerability to such disasters was blamed on its civil war, which damaged critical infrastructure and left it in poor condition before the storm. In the aftermath, several countries along the Mediterranean Sea pledged to provide aid to affected countries.”
