This list of wettest tropical cyclones in the United States presents the highest known rainfall totals from tropical cyclones and their remnants. These storms have moved into the lower 48 United States from the Atlantic Ocean, the Gulf of Mexico, and the eastern Pacific Ocean. The tropical cyclones and their remnants which have brought rainfall to Alaska, Puerto Rico, the U.S. Virgin Islands, Hawaii, Guam, and American Samoa are also included within this list.
Alabama
The wettest tropical cyclone to impact the state of Alabama was Hurricane Danny, which stalled over Mobile Bay for over 24 hours, and which led to significant rainfall.
Alaska
While no tropical cyclone has managed to track into Alaska, their remnants evolve into extratropical cyclones which bring rain to the state. The extratropical remains of Hurricane Ioke brought a record daily rainfall of to Bethel during September 2006. Rainfall is also documented to have fallen from the remains of Hurricane Fico in 1978.
American Samoa
Tropical cyclones impact the island chain with tropical storm-force winds once every three years, on average. The wettest known cyclone to affect the island group occurred early in 1966, when nearly fell at Vaipito.

Arizona
Hurricane Nora was the last tropical cyclone to enter the United States from Mexico at tropical storm strength. The rainfall which fell across the Mogollon Rim led to the state's 24-hour rainfall record.
Arkansas
Tropical Storm Allison in 1989 stalled for three days across southeast Texas which lead to prolonged rains across Arkansas. This way, Allison became the wettest known tropical cyclone to impact the state.
California
One of five known eastern Pacific tropical cyclones to bring tropical storm-force winds to the Southwest, Hurricane Kathleen accelerated northward ahead of an upper level trough, spreading heavy rains into the transverse ranges of southern California.
Colorado
Few tropical cyclone remnants originating from the eastern Pacific make it as far north as Colorado. Most recently, Javier dropped locally heavy rainfall exceeding over the higher terrain of western Colorado in 2004.

Connecticut
The wettest known tropical cyclone to impact New England is also the wettest known for the state of Connecticut. The flood from Hurricane Diane led to a significant death toll (nearly 200) from Pennsylvania eastward through southern New England.
Delaware
A large swath of heavy rainfall spread over the East coast along a frontal zone draping over the northern side of Hurricane Floyd. Over fell across portions of Delaware, the most recorded during the passage of a tropical cyclone or its remnants within the state borders.
Florida
The heaviest rainfall to occur in 24 hours was measured in Yankeetown during Hurricane Easy in 1950, which caused of precipitation. This is also the highest known point storm total maximum related to any tropical cyclone which has impacted Florida, and by itself would be the highest known rainfall total for any month, or any 24 hour period, from any location within Florida. This rainfall amount remained the national 24-hour rainfall record until Tropical Storm Claudette's landfall in 1979.
Georgia
Tropical Storm Alberto in 1994 looped across central Georgia, leading to 24-hour rainfall amounts exceeding across central sections of the state. It also became the wettest tropical cyclone on record for the state of Georgia, eclipsing the record set in 1929.
Guam
An average of three tropical storms and one typhoon pass within of Guam each year. Super Typhoon Pamela was not only a wet tropical cyclone for the island, but a destructive one as well. Since Pamela, wooden structures across Guam have been largely replaced by concrete structures in order to better weather typhoons.
Hawaii
This island state frequently sees rainfall from the remains of former eastern and central Pacific tropical cyclones. However, despite Hawaii's location in the subtropics, direct impacts by tropical cyclones are infrequent due to the protective influence of the Central Pacific Tropical Upper Tropospheric Trough (TUTT), which normally dissipates systems approaching Hawaii. Hurricane Hiki in 1950 led to significant rainfall in the mountains, with of rainfall reported. This is the most rainfall produced by a tropical cyclone on record within the United States.

Illinois
Hurricane Carla was a large hurricane which moved into Texas during September 1961. As it transitioned into an extratropical cyclone across the Great Plains and Midwest, heavy rainfall fell in a band on the poleward side of a frontal boundary extending northeast from Carla, leading to the wettest known event to be associated with a tropical cyclone or its remains across Illinois.
Indiana
Hurricane Tico led to significant rainfall from the southern Plains through the Ohio Valley along a frontal boundary ahead of the former tropical cyclone. Heavy rainfall in excess of fell across portions of Indiana, making Tico the wettest tropical cyclone to impact the state.
Iowa
Hurricane Carla was a large hurricane which moved into Texas during September 1961. As it transitioned into an extratropical cyclone across the Great Plains and Midwest, heavy rainfall fell in a band on the poleward side of a frontal boundary extending northeast from Carla, leading to the wettest known event to be associated with a tropical cyclone or its remains across Iowa.
Kansas
Heavy rainfall from Tropical Storm Frances (1998) fell from the western Gulf coast northward into the Great Plains. Heavy rainfall spread across portions of Kansas, with localized amounts above recorded.
Kentucky
Soon after moving inland, the Unnamed tropical cyclone of 1960 looped over South Texas, leading to heavy rains along the coastal plain near Port Lavaca. As it moved north-northeast, bursts of heavy rainfall were accompanied with the
system over Arkansas and Kentucky. The maximum in Kentucky not only represents their highest tropical cyclone-related rainfall amount on record, but also the state's all-time 24 hour precipitation record (through 1998).
Louisiana
Heavy rains and flooding are the primary problem associated with tropical cyclones across the Pelican State. Recent examples of flooding across the state from tropical cyclones include Tropical Storm Allison, Tropical Storm Frances (1998), Tropical Storm Allison (1989), and Tropical Storm Claudette (1979). Three of the four systems stalled across eastern Texas, prolonging the rainfall which occurred over Louisiana. If it were not for the intermittent invasions from tropical cyclones, rainfall during the months of August, September, and October would average about 25% less that it currently does.
Maine
The combined impact from a Nor'easter just one day before Daisy hit, and Hurricane Daisy, caused severe flooding in Maine, when rain fell for 65 consecutive hours in some locations. Rainfall from the two systems caused record rainfall in some areas in Maine.
Maryland
Eloise's remnants brought great moisture to the Northeast third of the United States in the combination of warm, tropical air and cold air from a cold front. From Virginia through New Jersey, of rain were reported, while New York and Pennsylvania experienced . Westminster, Maryland received the maximum amount from the storm in this region with a total of . The excessive rainfall across the Mid-Atlantic states led to overflown rivers from flash flooding.
Massachusetts
The wettest known tropical cyclone to impact New England is also the wettest known for the state of Massachusetts. The flood from Hurricane Diane led to a significant death toll (nearly 200) from Pennsylvania eastward through southern New England.
Michigan
Hurricane Carla was a large hurricane which moved into Texas during September 1961. As it transitioned into an extratropical cyclone across the Great Plains and Midwest, heavy rainfall fell in a band on the poleward side of a frontal boundary extending northeast from Carla, leading to the wettest known event to be associated with a tropical cyclone or its remains across Michigan.
Minnesota
Few tropical cyclone remnants originating from the eastern Pacific or Atlantic Basins make it as far north as Minnesota. Most recently, 2004's Hurricane Javier dropped locally heavy rainfall exceeding in localized spots.
Mississippi
Hurricane Georges stalled over the southern portion of the state, it produced torrential rainfall, exceeding locally. The heavy rainfall contributed to significant river overflowing, including the Tchoutacabouffa River at D'Iberville, which set a record crest of .
Missouri
Remnant tropical cyclones can move into the state which originate in either the Pacific or Atlantic hurricane basins. Tropical Storm Erin (2007) reintensified over Oklahoma leading to heavy rainfall in that state. As the system moved eastward, its surface low quickly dissipated. However, its mid-level circulation remained robust, leading to a burst of heavy rainfall across Missouri exceeding in isolated spots, which turned out to be to wettest tropical cyclone remnant on record for the state.
Montana
It is rare for tropical cyclone remnants originating from the eastern Pacific or Atlantic Basins to make it as far north as Montana. The remains of Kathleen dropped locally heavy rainfall approaching in localized spots.

Nebraska
Hurricane Carla was a large hurricane which moved into Texas during September 1961. As it transitioned into an extratropical cyclone across the Great Plains and Midwest, heavy rainfall fell in a band on the poleward side of a frontal boundary extending northeast from Carla, leading to the wettest known event to be associated with a tropical cyclone or its remains across Nebraska.
Nevada
Nevada is impacted by eastern Pacific tropical cyclones, or their remnants, every few years. The wettest event for the state was during Hurricane Doreen, when over fell in isolated spots.
New Hampshire
A large swath over heavy rainfall spread up the East coast along a frontal zone draping over the northern side of Hurricane Floyd. Nearly fell across portions of New Hampshire, the most recorded during the passage of a tropical cyclone or its remnants.
New Jersey
A large swath over heavy rainfall spread up the East coast along a frontal zone draping over the northern side of Hurricane Floyd, which produced over across portions of New Jersey.
New Mexico
Tropical cyclones, and their remnants, move into New Mexico from both the eastern Pacific and Atlantic basins. Although Atlantic Basin tropical cyclones are more unusual events, the rainfall record for New Mexico was from a tropical depression which moved across Texas from the Gulf of Mexico in October 1954.
New York
Tropical cyclones moving up the East coast bring rainfall to New York frequently. During Hurricane Connie, over fell in isolated spots, which is the most rainfall recorded with a tropical cyclone or its remains across the state.
North Carolina
Heavy rains accompany tropical cyclones and their remnants which move northeast from the Gulf of Mexico coastline, as well as inland from the western subtropical Atlantic ocean. As much as 15% of the rainfall which occurs during the warm season in the Carolinas is attributable to tropical cyclones. Over the past 30 years, the wettest tropical cyclone to strike the coastal plain was Hurricane Floyd of September 1999, which dropped over of rainfall north of Southport. In the mountains, Hurricane Frances of September 2004 was nearly as wet, bringing over of rainfall to Mount Mitchell.

Ohio
The state of Ohio can be impact by the remnants of both eastern Pacific and Atlantic tropical cyclones, with a bulk of the activity originating in the Gulf of Mexico. Hurricane Frederic in 1979, interacting with a nearby frontal zone, brought over of rainfall to isolated spots of the state, becoming the wettest known tropical cyclone, or remnant, to impact Ohio.
Oklahoma
Remnant tropical cyclones can move into the state which originate in either the Pacific or Atlantic hurricane basins. Most recently, Tropical Storm Erin (2007) reintensified over Oklahoma leading to heavy rainfall within the state. Rainfall exceeded in isolated spots, which turned out to be the third wettest tropical cyclone remnant on record for Oklahoma.

Although Hurricane Agnes was barely a hurricane at landfall in Florida, its major impact was over the Mid-Atlantic region, where Agnes combined with a non-tropical low to produce widespread rains of to with local amounts up to in western Schuylkill County in Pennsylvania . These rains produced widespread severe flooding from Virginia northward to New York, with other flooding occurring over the western portions of the Carolinas.
Puerto Rico
Puerto Rico has seen dramatic rainfall from tropical cyclones and their precursor disturbances. The most recent tropical cyclone-related deluge was from Hurricane Georges from September 1998, when 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 fell at Toro Negro Forest. Hurricane Eloise of 1975 dropped of rainfall at Dos Bocas, with falling in 24 hours.

Rhode Island
The wettest known tropical cyclone to impact New England is also the wettest known for the state of Rhode Island. The flood from Hurricane Diane led to a significant death toll (nearly 200) from Pennsylvania eastward through southern New England.
South Carolina
Portions of South Carolina experienced significant rainfall totals approaching with Tropical Storm Jerry (1995), which became the wettest known tropical cyclone to impact the state. The flash flooding covered numerous roadways and washed out bridges, with the statewide transportation damage totaling $4.5 million (1995 USD). River flooding was great across the state. In addition, the rainfall broke dams, flooded houses, and covered fields, causing a damage total of $10.1 million (1995 USD).
South Dakota
It is rare for tropical cyclone remnants originating from the eastern Pacific or Atlantic Basins to move as far inland as South Dakota. The remains of Javier in 2004 dropped locally heavy rainfall exceeding in localized spots.

Tennessee
Tropical Storm Chris (1982) moved inland into the Southeast, producing a burst of rainfall across Tennessee exceeding . This system stands as Tennessee's wettest known tropical cyclone.
Texas
The most serious threat from tropical cyclones in Texas residents is from flooding. The worst aspect about tropical cyclones is that the weaker they are, the more efficient they can be at producing heavy rains and catastrophic flooding. Systems with sprawling circulations, such as Hurricane Beulah, also tend to make good rainmakers. Slow moving systems, such as Tropical Storm Amelia (1978) also can produce significant rainfall over the Lone Star State. Amelia's storm total rainfall is the most recorded within the contiguous United States. Tropical Storm Claudette (1979) holds the national 24-hour rainfall record for the United States, with falling within a day.
United States Virgin Islands
