The Waccamaw River in Conway crested at 22.1ft (6.7m) on September 26, exceeding the Hurricane Matthew record of 19.1ft (5.8m). [10][11] Shortly thereafter, the system unexpectedly rapidly intensified within a small area of low wind shear in an otherwise adverse upper-level environment;[12] the hurricane's core structure, eye, and outer banding improved markedly, catching forecasters off-guard and intensifying beyond model outputs. Tropical cyclonesvariously defined as hurricanes, typhoons, and cyclonesregularly impact human populations and periodically produce devastating weather-related natural disasters. stage of development of tropical cyclone florence. Easterly trade winds propelled the disturbance along a west to west-northwest trajectory. A rain gage in Swansboro indicated accumulations of 14 to 15in (360 to 380mm) by 14:34UTC, exceeding radar estimations. [42] The system intensified again and reached its peak intensity with winds of 150mph (240km/h) and a pressure of 937mbar (hPa; 27.76inHg) at 18:00UTC.

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. A Potential Tropical Cyclone is a storm system that is not yet a tropical cyclone but has a high likelihood of becoming one and is anticipated to produce tropical storm or hurricane conditions on land within 48hours. 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 . On September 15, NCDOT asked drivers to avoid driving in North Carolina altogether, instructing them to take a detour at Richmond, Virginia using Interstate 64 west to Interstate 81 south into Tennessee to Interstate 40 west to Interstate 75 south into Georgia to Interstate 16 east back to Interstate 95.

From September79, Florence's forward momentum slowed as it turned west. A mandatory evacuation for visitors and tourists was issued on September 11 for Holden Beach, Oak Island, and Currituck. Once over land, the forward motion of the hurricane slowed to about 2 to 3 miles per hour. When the wind speed reaches 39 mph (63 km/h), it is called a tropical storm. [74], Florence's flooding in North Carolina and Virginia was compounded by earlier flooding during the summer that left the ground heavily saturated. The entirety of Horry and Marion counties also fell under curfews. Expanding outflow ventilated the cyclone, enabling continued growth. [1][26] Meteorologist Robbie Berg described the intensity forecasts for Florence as a "self-defeating prophecy" owing to the "nuances of the environmental shear". A cyclone will dissipate once it moves over land or over cooler oceans. [34][39][40], On September8, Virginia Governor Ralph Northam also declared a state of emergency. Over the next several days, the hurricane delivered historic amounts of rainfall across North and South Carolina, causing substantial flooding in many communities across, 12201 Sunrise Valley Drive Reston, VA 20192, Region 2: South Atlantic-Gulf (Includes Puerto Rico and the U.S. Virgin Islands), Region 12: Pacific Islands (American Samoa, Hawaii, Guam, Commonwealth of the Northern Mariana Islands), South Atlantic Water Science Center (SAWSC), Preliminary peak stage and streamflow data for selected U.S. Geological Survey streamgaging stations in North and South Carolina for flooding following Hurricane Florence, September 2018, South Atlantic Water Science Center (SAWSC) News, South Atlantic Water Science Center - Columbia, SC Office.

Florence degenerated into a post-tropical cyclone over West Virginia on September17 and was absorbed by another frontal storm two days later. Its low-level circulation became exposed as convection became displaced to the northeast and the previously well-defined eye dissipated. Yet each stage of the process entails a fresh contribution to greenhouse. At 22.4N / 46.2W, this also makes #Florence the furthest north category 4 hurricane east of 50W ever recorded in the Atlantic", Tropical Storm Florence Discussion Number 31, Tropical Storm Florence Discussion Number 33, "A lot of huge track shifts we've seen the last 3-4 days are also related to the downstream impact of #Jebi's #ET. On this Wikipedia the language links are at the top of the page across from the article title.

[18][19] Broad-scale conditionsmoderate wind shear, sea surface temperatures below 81F (27C), and low relative humidity valuesdid not favor further intensification. [22][23][24], Upon the designation of Potential Tropical Cyclone Six on August30, the government of Cape Verde issued tropical storm warnings for the islands of Brava, Fogo, and Santiago. Media coverage of the hurricane drew comparisons with Hurricane Floyd; Smithfield Foods, which owns many of eastern North Carolina's hog farms, had been criticized at the time for allowing the lagoons to overflow, and had promised improvements to prevent future incidents of pollution. [81][82], Strong winds in New Hanover County toppled numerous trees and power lines, while more than 90% of the county was left without electricity.

[147] South Carolina Governor McMaster applied for $1.2billion in federal funding for recovery, including $165million under the National Flood Insurance Program and $125million for agriculture. Intensifying to a tropical storm the following day, Florence embarked on a west-northwest to northwest trajectory over open ocean. Analyses after the hurricane indicate that warming led to an increase in total rainfall of around 5% and an increase in diameter of around 1.5 miles. On March 11, 2005, a greatly-weakened Ingrid re-emerged over open water in the Gulf of Carpentaria. A collapse of steering currents was anticipated around the time of landfall on September14, which would result in the hurricane meandering near the coast or just inland for a prolonged period of time. Tropical storm looks like a little hurricane, but it has no eye in its centre. The wave steadily organized, and strengthened into a tropical depression on the next day near Cape Verde. [8] Through much of the day and into August31, convection remained confined to the southwest of the disturbance within a monsoon trough and precluded its classification as a tropical cyclone. [30], In anticipation of adverse conditions, Norwegian Cruise Lines and Oceania Cruises adjusted itineraries for Norwegian Escape, Norwegian Dawn, and Sirena to avoid crossing the hurricane's path and not dock in Bermuda.

A total of 226homes were damaged and other 2were destroyed. Early on September14, Florence made landfall in the United States just south of Wrightsville Beach, North Carolina as a Category 1 hurricane, and weakened further as it slowly moved inland under the influence of weak steering currents. A new rain band developed closer to the storm's core over New Hanover, Brunswick, Pender, Bladen, and Sampson counties. Projections prior to landfall made the case that the hurricane could be up to 50% larger and 50 miles wider given the effects of anthropogenic warming. The storm had reportedly cut power to more than 500,000 customers in North and South Carolina by the time of landfall and caused the roof of a hotel in Jacksonville, North Carolina to collapse that morning. 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 August30, 2018. Flooding persisted along multiple rivers for more than a week after the storm. Torrential rains from the storm itself, estimated at 30 inches (760mm), also caused a swamp to spill into the cooling pond. However, the twister in Chesterfield County, rated EF2, damaged several buildings between Winterpock and Bon Air and destroyed a warehouse, causing one death and at least one injury.
