According to Hurricane Center: “Data from an Air Force Reserve hurricane hunter aircraft along with satellite imagery and various intensity estimates indicate that Florence has weakened instead of strengthening. However, while the hurricane hasn’t strengthened in terms of peak winds, the inner-core and outer wind fields have continued to expand, resulting in an increase the cyclone’s total energy, which will create a significant storm surge event. The upper-level outflow remains impressive and is still expanding except toward the south.”
