The depression drifted eastward under the influence of the dissipating frontal trough and intensified into Tropical Storm Florence, as confirmed by Hurricane Hunters. The storm turned northward on September 9 and accelerated toward the northern Gulf Coast under the influence of a mid- to upper-level trough. Florence became a hurricane just hours before landfall on the western Mississippi Delta. The storm rapidly weakened over southeastern Louisiana and lost all its deep convection as it passed over the New Orleans area. Florence became a depression on September 10 near Baton Rouge and dissipated the next day over northeast Texas.
