Weather tracker: Libya floods caused by Storm Daniel ‘medicane’

Country hit by record rainfall that followed Mediterranean storm with similarities to tropical cyclone

After battering Greece last week, Storm Daniel caused further devastating floods, this time affecting Libya. As the storm moved across the Sahara, it developed into what is informally known as a medicane, a storm in the Mediterranean that develops characteristics similar to those seen in tropical cyclones, notably a central eye. The particularly warm Mediterranean water fuelled by the extreme heat seen over southern Europe this summer, helped strengthen Daniel as it approached Libya.

By Saturday 10 September, Daniel had reached north-eastern Libya, with winds of 70-80mph according to Libya's National Meteorological Centre. The devastation then came from extreme rainfall, as 24-hour totals of 150mm-240mm were widely recorded in the region. One station in the city of Al-Bayda recorded a rainfall total of 414.1mm in 24 hours, a new record for the area. These torrential rains caused two dams to collapse, which resulted in devastating flash flooding that has killed thousands of people.
