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 vapor contained in the moist air. They are fuelled by a different heat mechanism than other cyclonic windstorms such as nor'easters, European windstorms, and polar lows, leading to their classification as 'warm core' storm systems. Most tropical cyclones originate in the doldrums near the Equator, approximately 10 degrees away.
The term 'tropical' refers to both the geographic origin of these systems, which form almost exclusively in tropical regions of the globe, and their formation in maritime tropical air masses. The term 'cyclone' refers to such storms' cyclonic nature, with anticlockwise rotation in the Northern Hemisphere and clockwise rotation in the Southern Hemisphere. Depending on its location and intensity, a tropical cyclone can be referred to by names such as 'hurricane', 'typhoon', 'tropical storm', 'cyclonic storm', 'tropical depression', or simply 'cyclone'.

Hurricane Mitch was one of the most powerful hurricanes ever observed, with maximum sustained winds of 180 mph (290 km/h). The storm was the thirteenth tropical storm, ninth hurricane, and third major hurricane of the 1998 Atlantic hurricane season. At the time, Mitch was the strongest hurricane ever observed in the Atlantic Ocean in the month of October, though it has since been surpassed by Hurricane Wilma of the 2005 season. Mitch formed in the western Caribbean Sea, eventually reaching Category 5 status on the Saffir-Simpson Hurricane Scale. It remained nearly stationary over water for several days, and eventually weakened, striking Honduras as a minimal hurricane.
Though Mitch weakened before striking land, it drifted just off the coast of Central America from October 29 to November 3, dropping historic amounts of rainfall, with unofficial reports of up to 75 inches (1,900 mm). Deaths due to catastrophic flooding made it the second deadliest Atlantic hurricane in history; nearly 11,000 people were killed with over 8,000 left missing by the end of 1998. The flooding caused extreme damage, amounting to around $7 billion (2005 USD), though exact totals will likely never be known.

Tropical cyclone anniversaries
January 7
- 1966 - Cyclone Denise struck Réunion, producing 1,825 mm (71.9 in) of rainfall at Foc-Foc. As of 2012, this is the highest 24 hour rainfall total worldwide.
- 1998 - Three cyclones (pictured) – Ron (right), Susan (center), and Katrina (left) – are active over the southern Pacific Ocean. The former two were among the strongest on record for the region, while the latter lasted 24 days while moving erratically around Australia.
January 8
- 1979 - Typhoon Alice (pictured) reached its peak with 215 km/h (130 mph) winds in the open Pacific Ocean. Alice caused extensive damage in the Marshall Islands.
- 2010 - Cyclone Edzani became a very intense tropical cyclone, the first in the basin in five years.
January 9
- 1880 - An unnamed tropical cyclone struck land near Onslow, Western Australia. The storm created an 8‑metre (26‑ft) storm tide and sank the ship Adalia, drowning some of the crew.
- 2006 - Cyclone Clare (pictured) struck Pilbara, Western Australia, causing heavy rainfall but minor damage.
