In Context
A forecast track is a best estimate, not a guaranteed path, which is why it's shown alongside a cone of uncertainty that widens the further out the forecast extends.

Cone of Uncertainty
The cone of uncertainty is the shaded area shown on a forecast track map representing the range of possible paths a tropical cyclone's center could take, based on the historical accuracy of past forecasts.
Eastward Movement
Eastward movement describes a tropical cyclone tracking from west to east, an uncommon direction usually associated with a weakening or dissipating system caught in unusual steering flow.
Forward Speed
Forward speed is how fast a tropical cyclone's center is moving along its track, distinct from its wind speed, which measures how strong the winds are rotating around that center.
Landfall
Landfall is the point at which a tropical cyclone's center crosses from open water onto land.
Northeast Track
A northeast track describes a tropical cyclone that has recurved, shifting from a westward or northwestward path toward the northeast, typically after clearing the Philippines or Taiwan.
Northwest Track
A northwest track is a common path for Northwest Pacific tropical cyclones, curving from an initial westward motion toward the northwest as they near or cross the Philippines.
Recurvature
Recurvature is a tropical cyclone's shift from a westward track to a northward or northeastward one, usually caused by a break or weakening in the steering ridge of high pressure.
Second Landfall
A second landfall occurs when a tropical cyclone crosses back over water after an initial landfall and then makes landfall again on a different part of the coast or a different island.
