Many people seem confused on what landfall means in the context of an incoming typhoon. Landfall occurs when the center of a typhoon crosses from the sea to land. For example, if the center of a typhoon crosses from the Philippine sea to the Isabela coast, then it made landfall on Isabela.
Because of this sea-to-land definition, landfall can occur multiple times with the same typhoon. This is very common in the Visayas region. A typhoon makes multiple landfalls as the typhoon crosses from sea to island to sea then to another island.
Typhoon Uwan is projected to make landfall on the province of Aurora tomorrow evening (Sunday).
