Cyclone (Storm) Daniel

Storm Daniel, also known as Cyclone Daniel, was the deadliest Mediterranean tropical-like cyclone in recorded history, as well as one of the costliest tropical cyclones on record outside of the north Atlantic Ocean. 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; a high-pressure zone sandwiched between two zones of low pressure, with the isobars shaping like the Greek letter omega.
