<P> Landfall is the event of a storm or waterspout moving over land after being over water . </P> <P> A tropical cyclone is classified as making landfall when the center of the storm moves across the coast; in strong tropical cyclones this is when the eye moves over land . This is where most of the damage occurs within a mature tropical cyclone, such as a typhoon or hurricane, as most of the damaging aspects of these systems are concentrated near the eyewall . Such effects include the peaking of the storm surge, the core of strong winds coming ashore, and heavy flooding rains . These coupled with high surf can cause major beach erosion . In low - lying areas, the storm surge can stay inland for a long time and mix with chemicals already in the area to create a toxic mess . When a tropical cyclone makes landfall, the eye closes in upon itself due to the weakening process, which causes surf to decrease . Maximum sustained winds will naturally decrease as the cyclone moves inland due to frictional differences between water and land with the free atmosphere . </P> <P> Landfall is distinct from a direct hit . A direct hit is where the core of high winds (or eyewall) comes onshore but the center of the storm may stay offshore . The effects of this are quite similar to a landfall, as this term is used when the radius of maximum wind within a tropical cyclone moves ashore . These effects are high surf, heavy rains that may cause flooding, water buildup along the coast with minor storm surge, coastal beach erosion, high winds, and possibly severe thunderstorms with tornadoes around the periphery . </P>
