The Atlantic tropical cyclones of 2018 collectively caused 172 fatalities and just over $50.2 billion in damage. [24] The Atlantic hurricane season officially ended on November 30, 2018. [22] Tropical cyclogenesis began with the formation of Tropical Storm Alberto on May 25, marking the fourth consecutive year that activity began early. [22]
Tropical cyclone tracking chart. A tropical cyclone tracking chart is used by those within hurricane-threatened areas to track tropical cyclones worldwide. In the north Atlantic basin, they are known as hurricane tracking charts. New tropical cyclone information is available at least every six hours in the Northern Hemisphere and at least every ...

The Tropical Cyclones Portal. A tropical cyclone is a storm system characterized by a large low-pressure center, a closed low-level circulation and a spiral arrangement of numerous thunderstorms that produce strong winds and heavy rainfall. Tropical cyclones feed on the heat released when moist air rises, resulting in condensation of water ...
Map of all North Atlantic tropical cyclone tracks from 1851 to 2019. Tropical storms are shown in green. On the Saffir–Simpson scale, a tropical cyclone reaches tropical storm status when it attains maximum sustained winds of between 39 knots (45 mph; 72 km/h; 20 m/s) and 72 knots (83 mph; 133 km/h; 37 m/s).
