It was the eleventh named storm, eighth hurricane and sixth major hurricane of the 2004 season. Karl formed on September 16, originating from a strong tropical wave that emerged off of Africa. It rapidly intensified, becoming a major hurricane on two occasions. Karl peaked as a strong Category 4 hurricane on the Saffir-Simpson hurricane scale on September 21 with 145 mph (230 km/h) winds. It weakened as it moved northward, becoming extratropical on September 24 in the north Atlantic and becoming absorbed by another system on September 28. The extratropical storm affected the Faroe Islands, but no damage was reported there and no lives were lost.
