Hurricane Florence was a powerful and long-lived Cape Verde hurricane that caused catastrophic damage in the Carolinas in September2018, primarily as a result of freshwater flooding due to torrential rain. Inland flooding from Florence inundated cities such as Fayetteville, Smithfield, Lumberton, Durham, and Chapel Hill.

Like any tropical cyclone, there are several main requirements for typhoon formation and development: (1) sufficiently warm sea surface temperatures, (2) atmospheric instability, (3) high humidity in the lower to middle levels of the troposphere, (4) enough Coriolis effect to develop a low pressure center, (5) a pre- , The seventh tropical depression, fifth named storm and the second tropical cyclone of the season, Eloise's origins can be traced to a disturbance over the central portion of the South-West Indian Ocean basin which developed into a tropical depression on 16 January, and strengthened into a tropical storm on 17 January, .

Farther south along the Waccamaw River, homes in a neighborhood in Socastee were flooded with as much as 8ft (2.4m) of water. The university collaborated with the University of North Carolina at Asheville to house students who had no options for safe shelter. The first phase is the formation of the tropical cyclone, and numerous factors can lead to this, such as The four stages in the life cycle of an extratropical cyclone are: (1) the initial state, (2) the incipient stage, (3) the mature stage, and (4) the occlusion stage.

[9], Development of a small central dense overcast and a mid-level eye feature signified Florence's intensification to hurricane strength early on September4, roughly 1,240 miles (2,000km) west-northwest of Cape Verde. It converts the energy available from a warm ocean surface into strong vertical air currents and horizontal wind speeds via the evaporation of warm water from the ocean surface and the subsequent . This is essential for the continuing development of the cyclone, by providing energy into the storm system. See animated graphic below:", "Intensity at 18z has been increased to 115kt -- #Florence is officially a category 4 hurricane.

[140] Many individuals whose homes were ruined due to the hurricane were offered aid through Red Cross shelters, rental assistance from FEMA, or utilizing undamaged rental properties until their homes are livable. The storm begins as a tropical disturbance, which typically occurs when loosely organized cumulonimbus clouds in an easterly wave begin to show signs of a weak circulation.
