Katrina stayed at hurricane strength in Mississippi, but it soon weakened. It lost hurricane strength more than 150 miles (240 km) inland, near Meridian, Mississippi. Katrina was then lowered into a tropical depression near Clarksville, Tennessee and broke in half. One half of the storm continued to race northward, affecting the Central United States, and it was last noticeable in the eastern Great Lakes region. On August 31, it was absorbed by a frontal boundary and became a powerful extratropical low, causing 1.97–6.69 inches (50–170 mm) of rain in 12 hours. It also caused gale-force wind gusts from 31 to 61 mph (50 to 98 km/h) in southeastern Quebec and northern New Brunswick. In the region of Saguenay and Côte-Nord, rain caused breakdowns and failure in roads. The Côte-Nord region was isolated from the rest of Quebec for at least 1 week. However, the other half of Katrina broke off in the eastern part of the Appalachians, which caused a major tornado outbreak in the area from central Georgia to central Pennsylvania. The tornadoes were strong, killing two people and creating heavy damage.
