Hurricane Florence is currently a powerful Category 4 hurricane over the Atlantic Ocean, threatening the Southeastern United States and the U.S. Mid-Atlantic states. The sixth named storm, third hurricane and the first major hurricane of the 2018 Atlantic hurricane season, Florence originated from a strong tropical wave that emerged off the west coast of Africa on August 30. Steady organization resulted in the formation of a tropical depression on the next day near Cape Verde. Progressing along a steady west-northwest trajectory, the system acquired tropical storm strength on September 1, and fluctuated in strength for several days over open ocean.

An unexpected bout of rapid intensification ensued on September 4–5, culminating with Florence becoming a Category 4 major hurricane on the Saffir–Simpson scale—estimated maximum sustained winds were 130 mph (215 km/h). Thereafter, hostile environmental conditions tore the storm apart, and Florence degraded to a tropical storm by September 7. Shifting steering currents led to a westward turn into a more suitable environment, and the system regained hurricane strength on September 9 and major hurricane status by September 10. At 16:00 UTC on September 10, Florence again became a Category 4 hurricane, later reaching a new peak intensity with winds of 140 mph (220 km/h) and a central pressure of 939 mbar (27.7 inHg). Afterwards, Florence weakened slightly as it underwent an eyewall replacement cycle, but began to restrengthen late on September 11.
