The 2013 Atlantic hurricane season was a well below average Atlantic hurricane season in terms of the number of hurricanes. It was the first since 1994 with no major hurricanes, Category 3 or higher on the Saffir–Simpson scale , and the first in the satellite era where no hurricanes reached Category 2 strength.
2 Only systems that formed either on or after January 1, 2013 are counted in the seasonal totals. 3 Only systems that formed either before or on December 31, 2013 are counted in the seasonal totals. 4 The wind speeds for this tropical cyclone/basin are based on the IMD Scale which uses 3-minute sustained winds.
The 2013 Atlantic hurricane season was an event in the annual hurricane season in the north Atlantic Ocean. It featured below-average tropical cyclone activity, [nb 1] with the fewest hurricanes since the 1982 season. [2] The season officially began on June 1, 2013 and ended on November 30, 2013.
An example of a chart for Hurricane Matthew showing its five-day forecast track A black and white track chart for Hurricane Floyd (1999) using a conic projection. Lines or dots connecting symbols can be varying colors, solid, dashed, or symbols between the points depending on the intensity and type of the system being tracked. [26]
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 ...
The cone represents the probable position of a tropical cyclone's circulation center, and is made by drawing a set of circles centered at each forecast point—12, 24, 36, 48, and 72 hours for a three-day forecast, as well as 96 and 120 hours for a five-day forecast. The radius of each circle is equal to encompass two-thirds of the historical ...

Tropical cyclone forecasting is the science of forecasting where a tropical cyclone's center, and its effects, are expected to be at some point in the future. There are several elements to tropical cyclone forecasting: track forecasting, intensity forecasting, rainfall forecasting, storm surge, tornado, and seasonal forecasting.
