List of the wettest tropical cyclones by country

Bangladesh has been the scene of the greatest tropical cyclone casualties in recent times. The country is quite flat and generally lies near sea level.

This country has terrain mainly across its southern sections, with elevations up to about 3,700 feet (1,100 m).^[51] The highest reported rainfall in what was formerly British Honduras occurred during Hurricane Keith in 2000 when 32.67 inches (830 mm) of rain fell in a 24‑hour period at Phillip Goodson International Airport in Belize City.^[52] Equally heavy rains could have fallen during Hurricane Hattie of 1961 and Hurricane Fifi of 1974.

Tropical cyclones are usually in transition to extratropical cyclones by the time they reach Atlantic Canada, though occasionally they retain their tropical status. No tropical cyclone has ever hit Canada's Pacific coast.

China is a mountainous country, which leads to rapid dissipation of cyclones that move inland as well as significant amounts of rain from those dissipating cyclones. Typhoon Nina (1975) caused the collapse of two huge reservoirs and ten smaller dams when 1,062 millimetres (41.8 in) fell in Henan during a 24‑hour period, which is the record for Mainland China. Typhoon Sam of the 1999 Pacific typhoon season became the wettest known tropical cyclone to impact Hong Kong since records began in 1884, breaking a 73‑year‑old record.^[75] Precipitation associated with tropical cyclones and their remains can bring snow to Tibet. An early October 2004 tropical depression brought daily precipitation of 6 centimetres (2.4 in) of liquid equivalent precipitation to Che-Ku county in the form of heavy snow, which was a new October daily precipitation record for both rain and snow. This led to a loss of 340,000 kg of food, 230,000 kg of forage grass, and 263 livestock in the snowstorm.^[76]

Hurricane Flora of October 1963 drifted across Cuba for four days, leading to extreme rainfall across the mountainous island country. During the heaviest 24‑hour period of rainfall, 735 millimetres (28.9 in) of rain fell at Santiago de Cuba. Total amounts of 2,033 millimetres (80.0 in) over 4 days and 2,550 millimetres (100 in) over 5 days produced staggering loss of life in Cuba, where over 2000 perished.^[94]

The islands of the eastern Caribbean are constantly threatened by tropical storms and hurricanes, mainly between August and October. Dominica is a rugged island, with spots of elevation as high as nearly 4,750 feet (1,450 m).^[95] As Hurricane Jeanne moved through the region, 422.3 millimetres (16.63 in) of rain fell during the 24‑hour period ending on the morning of September 15, 2004.^[96]

The Dominican Republic, has some of the highest terrain surrounding the Caribbean Sea, with Pico Duarte peaking at 10,700 feet (3,300 m) above sea level.^[101] Most of the tropical cyclone rainfall totals on the list below are 24‑hour maxima, which likely underrepresent the storm total.

Orography from the volcanic islands of Fiji has led to significant rainfall during tropical cyclone passages, which occur roughly once a year.

Tropical Storm Agatha in May 2010 became the second-wettest tropical cyclone in the nation's history when it slowly developed while remaining nearly stationary to the southwest of Guatemala, before turning northeast and dissipating across inland Central America.^[164]

Haiti that makes up three-eighths of Hispaniola,^[170][171] is a mountainous country that has experienced some of the most powerful hurricanes on record, including Hurricane David. Its three mountain ranges have peaks as high as 8793 feet/2680 meters above sea level.^[172]

India can be struck by cyclones that form in the Bay of Bengal or the Arabian Sea.

The precursor tropical disturbance of Tropical Cyclone Inigo in April 2003 dropped heavy rainfall in eastern Indonesia. The rainfall caused flash flooding and mudslides, primarily in Flores but also on West Timor^[200] and Sumba.^[201] In some locations, the depth of the floodwaters reached 5 metres (16 ft). The Oessao River in West Timor exceeded its banks, which flooded seven villages. In Kupang in West Timor, the system destroyed hundreds of homes and large fields of corn, bean, and rice crop. Heavy damage was reported near Ende, where flooding and mudslides destroyed 20 houses and destroyed the roads connecting to East Flores. The city airport was flooded with one meter (3 ft) of water, preventing aerial transportation and which left the city temporarily isolated. In East Flores Regency in eastern Flores Island, the system left 75 destroyed houses, along with 77 severely damaged and a further 56 receiving light damage.^[200]

This mountainous island country of Jamaica can get lashed with rainfall by slow-moving tropical cyclones in the western Caribbean Sea. Its interior, the Blue Mountains, reach a height of 7,400 feet (2,300 m) above sea level.^[206]

The mountainous island archipelago is constantly struck by typhoons recurving out of the tropics, which are normally in extratropical transition as they pass through Japan. Typhoon Namtheun of the 2004 Pacific typhoon season holds the national 24-hour precipitation record with 1,317 millimetres (51.9 in) observed in Kisawa village,^[214] surpassing the previous record of 1,140 mm (45 in) set during Typhoon Fran in 1976.^[215]

Tropical cyclones occasionally threaten this central Pacific island. Hurricane Celeste of 1972 brought 6.21 inches (158 mm) to the isle around August 19.^[234]

The Korean Peninsula experiences typhoons regularly. Tropical cyclones which impact southern China also lead to, on average, five heavy rainfall events per year across the Korean peninsula.^[235]

The north end of the island, known as the Tsaratanana Massif region, contains terrain with elevations up to 9417 feet/2880 meters.^[246]

Hurricane Wilma of 2005 drifted over the northeast portion of the Yucatán peninsula for a couple of days, dropping significant rains. A report of 1,576 millimetres (62.0 in) was reported by the Servicio Meteorológico Nacional in Mexico,^[261] which is the wettest known 24-hour rainfall amount ever measured in Mexico. Second on the list is from Hurricane John in 2024, which accumulated up to 1,442 millimetres (56.8 in) of rain at Acapulco in Guerrero.^[262] Below is a list of the highest known storm total rainfall amounts from individual tropical cyclones across Mexico. Most of the rainfall information was provided by the Mexico's National Weather Service, Servicio Meteorológico Nacional, which is a part of the National Water Commission, Comisión Nacional del Agua.

The elevation of the country increases to the west, with mountains on its highest plateau reaching nearly 8,000 feet (2,400 m).^[279]

Some of the highest elevations on the planet lie in Nepal. Eight out of fourteen highest peaks in the world lie in the Nepalese Himalaya including the highest peak of the World, Mt. Everest (8848 m).^[287] During a tropical depression that affected the Indian Subcontinent in 2004, 51.3 millimetres (2.02 in) of rain fell at Kathmandu airport in the 24‑hour period ending at 1200 UTC on October 7.^[76]

Most tropical cyclones which pass near New Zealand are in extratropical transition (ET) or have become extratropical, which can enhance their heavy rainfall threat.

During the passage of Tropical Cyclone Heta in January 2004, the Niue Meteorological Station reported a record 24-hour rainfall of 999.2 millimetres (39.34 in).^[313]

Tropical cyclones for the Arabian Sea usually affect Pakistan. Tropical cyclones from the Bay of Bengal can affect Pakistan, though they usually weaken by the time they reach the Pakistani coastline.^[322]
