ECMWF aims to provide accurate medium-range global weather forecasts out to 15 days and seasonal forecasts out to 12 months. [11] Its products are provided to the national weather services of its member states and co-operating states as a complement to their national short-range and climatological activities, and those national states use ECMWF's products for their own national duties, in ...
The first dynamical hurricane track forecast model, the Sanders Barotropic Tropical Cyclone Track Prediction Model (SANBAR), [9] was introduced in 1970 and was used by the National Hurricane Center as part of its operational track guidance through 1989. It was based on a simplified set of atmospheric dynamical equations (the equivalent ...
1933 Chesapeake–Potomac hurricane – Category 4 hurricane that took a similar track to Florence as it approached the US, before making landfall near Chesapeake Bay; Hurricane Hazel (1954) – One of the strongest tropical cyclones to affect the Carolinas; Hurricane Gracie (1959) – Category 4 hurricane that made landfall in South Carolina
Also known as spaghetti plots, these models show where a tropical system, such as a hurricane, may go. The more they are clustered together, the higher the confidence in the forecast.

Total damage between the two states reached an estimated $24 billion, ranking Florence as the ninth-costliest hurricane in United States' history. [1] Florence weakened below hurricane strength by 00:00 UTC on September 15. Its close proximity to the coastline enabled it to maintain its organization and only slowly degrade. [1]
Over the past two decades, the National Hurricane Center’s one- to three-day track forecast errors have diminished by 75%, with reductions of about 60% at four- and five-day lead times.
The HWRF computer model is the operational backbone for hurricane track and intensity forecasts by the National Hurricane Center (NHC). [2] The model will use data from satellite observations, buoys, and reconnaissance aircraft, making it able to access more meteorological data than any other hurricane model before it. [2]
