In Context
Landfall doesn't mean the danger is over. A typhoon can retain damaging winds and heavy rain for hours after landfall, and provinces well inland from the coast can still see flooding and landslides long after the eye has passed.

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.
Forecast Track
A forecast track is the projected future path of a tropical cyclone, issued by PAGASA and other agencies and updated with each new bulletin as conditions change.
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.
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.
