List of wettest tropical cyclones by country

This is a list of wetest tropical cyclones by country, using all known available sources. Data is most complete for Australia, Cuba, the Dominican Republic, Japan, Hong Kong, Mexico, Taiwan, Yap, Chuuk, and the United States, with fragmentary data available for other countries. The French region of Réunion holds several world records for tropical cyclone rainfall, due to the rough topography and its proximity to the Indian ocean.

Bangladesh has been the scene of the most epic 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 . The highest reported rainfall in what was formerly British Honduras occurred during Hurricane Keith in 2000 when of rain fell in a 24 hour period at Phillip Goodson International Airport in Belize City. It should be noted that equally heavy rains could have fallen during Hurricane Hattie/Simone/Inga of 1961 and Hurricane Fifi of 1974.


Bermuda has not historically received overwhelming rains out of tropical cyclones. This could be because of the rapid pace storms usually pass the island and the lack of mountains on the island.



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 1062 mm/41.81 inches fell in Henan Province 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. The mountainous island of Taiwan province sees extreme rains from tropical cyclones, particularly in its central mountain range. Precipitation associated with tropical cyclones and their remains can bring snow to Tibet. An early October 2004 tropical depression brought daily precipitation of 60 mm/2.4 inches liquid equivalent 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.

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 mm/28.94" of rain fell at Santiago de Cuba. Total amounts of 2033 mm/80.04" over 4 days and 2550 mm/100.40" over 5 days produced staggering loss of life in Cuba, where over 2000 perished.

Dominica, Eastern Caribbean

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 . As Hurricane Jeanne moved through the region, of rain fell during the 24 hour period ending on the morning of September 15, 2004.

Dominican Republic

This country, taking up two-thirds of Hispaniola, has some of the highest terrain surrounding the Caribbean Sea, with Pico Duarte peaking at above sea level. Most of the tropical cyclone rainfall totals on the list below are 24 hour maxima, which likely underrepresent the storm total.

Federated States of Micronesia


Elevations of the islands surrounding Chuuk lagoon reach a height of about . Typhoon Chataan led to excessive rainfall on this island from June 23-July 3 of 2002, when a total of 939 mm/36.96 inches fell. During the time frame when Chataan was declared a tropical cyclone from July 1-3, 622 mm/24.49 inches fell, with 506 mm/19.92 inches falling on the 2nd alone at the international airport.

The wettest known tropical cyclone for the island was Ruby in 1982, which drifted in the island's vicinity for several days during its initial development phase.

Typhoon Dainmu went near Ulithi, an atoll in Yap State, in mid-June 2004. A 24 hour rainfall of 102.8 mm/4.05" was recorded at Falalop Island ending at 0000 UTC on the 13th.


Orography from the volcanic islands of Fiji has led to significant rainfall during tropical cyclone passages, which occur roughly once a year. Tropical Cyclone Ami of January 2003 led to disastrous flooding across the northern and eastern sections of the island group. The coastal side of Vatuwiri on Taveuni Island measured 311 mm/12.24" of rainfall on January 13.



Hurricane Marilyn moved directly across the island in mid-September 1995, bringing the highest known rainfall totals to the island from a tropical cyclone.


Martinique is a mountainous island at the fringe of the eastern Caribbean Sea.

Réunion Island (Indian Ocean)

The mountainous island of Réunion has experienced some of the highest rainfall totals from tropical cyclones around the world. Three tropical cyclones have staked their place in rainfall history:

Unnamed Tropical Cyclone (April 8-10, 1958): World record for 48 hours set at Aurere.

Tropical Cyclone Denise (January 7-8, 1966): World record for 12 hours and 24 hours set at Foc-Foc.

Tropical Cyclone Gamede (February 24-28, 2007): World record for 72 hours set at Commerson Crater. Gamede also holds the world record for accumulated rainfall through nine days.

During late January 2002, Tropical Cyclone Dinah dropped significant rains on the island. The highest amounts were over a 48 hour period at the Bellecombe resting place (a volcano lodge) and a storm total at Pierrefonds.


The mountainous country of Haiti 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.

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 and Sumba. In some locations, the depth of the floodwaters reached . 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.

This island chain frequently sees rainfall from the remains of former eastern and central Pacific tropical cyclones, but direct impacts of tropical cyclones are infrequent despite its location in the subtropics due to the protective influence of the Central Pacific Tropical Upper Tropospheric Trough (TUTT) which normally dissipates systems approaching Hawaii. The highest amount reported statewise was during Hurricane Hiki of 1950, when 1321 mm/52.00 inches fell in the mountains.. More recently, Hurricane Kenneth deposited 305 mm/ 12.00 inches within the 50th state.

The most recent tropical cyclone-related deluge was from Hurricane Georges from September 1998, when 775 mm/30.51 inches of rain was measured at Jayuya. The heaviest rainfall noted over the past 30 years was from the precursor disturbance to Tropical Storm Isabel (1985), when 804 mm/31.67 inches fell at Toro Negro Forest. Hurricane Eloise of 1975 dropped 946 mm/33.29 inches of rainfall at Dos Bocas, with 586 mm/23.07 inches falling in 24 hours.
