Lukas was a Category 5 windstorm that formed in early February. Lukas is the first of six Category 5 windstorms. In late November, Lukas was upgraded from a Category 4 windstorm.
On 3 February, a low pressure system with a frontal wave and a central pressure of 1000 mb was designated Lukas by the Free University of Berlin (FU-Berlin). Only six hours later, a buoy near the center of the storm reported an air pressure drop of 25.5 millibars. By later that day, Lukas had a central pressure of 955 mbar near the Faroe Islands. On 4 February, a ship just north of Scotland reported a fall 24.5 millibars in 3 hours, the the second lowest after Lothar in 1999. The next day saw strong winds, up to 105 mph on the Cairngorms summit in Scotland. The central pressure dropped even more to 950 mbar. The warm front of Lukas ran from the storm center south-westwards to Brittany and his cold front ran from the northern North Sea of Southern Ireland. During the late hours of the 4th of February, the storm departed from western and central Europe. However, the Lukas I stayed over the Norwegian Sea with a central pressure of 965 mbar and Lukas II was hanging over the Baltic Sea with a central pressure of 985 mbar. In Germany, in the following days, temperatures ranged between 6°C and 9°C, but nighttime temperatures in southern Germany were below zero. On February 7, Lukas moved out of FU-Berlins area of responsibility and later dissipated on the 9th of February.
