Hurricane Maria losing its characteristic structure after making landfall in Puerto Rico
Hurricane Maria losing its characteristic structure after making landfall in Puerto Rico

Landfall is the event of a storm moving over land after being over water. More broadly, and in relation to human travel, it refers to 'the first land that is reached or seen at the end of a journey across the sea or through the air, or the fact of arriving there'.[1]

Tropical cyclone

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.[2] 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.[citation needed] 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.[3]

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.[4] 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.

Storms, e.g., hurricanes, can be quite wide. Potentially dangerous winds, rain and flooding may impact an area near the center of the storm even though technically landfall may not have occurred. Accordingly, it may be helpful, to gauge the anticipated impact of such storms, to be aware of their general location, and land masses adjacent to the major thrust of the storm.

Tornado or waterspout

When a tornadic waterspout makes landfall it is reclassified as a tornado,[5] which can subsequently cause damage to areas inland of the coast. When a fair weather waterspout makes landfall it usually dissipates quickly due to friction and a reduction in the amount of warm air supplied to the funnel.[6]
