Tropical cyclones move into the contiguous United States from the Atlantic Ocean, the Gulf of Mexico, and the eastern Pacific Ocean. The highest rainfall totals in the country have been measured across the Gulf Coast and lower portions of the Eastern Seaboard. Intermediate amounts have been measured across the Southwest, New England, and the Midwest. The northern Great Plains and Pacific Northwest have received the lowest amounts, as those regions lie exceptionally far from the breeding grounds of Atlantic and Eastern Pacific tropical cyclones.
The wettest tropical cyclone in the United States storm on record is Hurricane Harvey, which dumped 60.58 in (1,539 mm) of rain on Southeast Texas in 2017. Tropical Storm Claudette holds the national 24-hour rainfall record: 42.00 in (1,067 mm) in Alvin, Texas.

No storm has ever affected Alaska as a tropical cyclone, but extratropical remnants of tropical cyclones have brought heavy rainfall to the state. Examples include the extratropical remnants of Hurricane Fico in 1978. [10]
Tropical cyclones affect the island chain with tropical storm-force winds once every three years, on average. [11] The wettest known cyclone to affect the island group occurred early in 1966, when nearly 19 inches (480 mm) fell at Vaipito. [1]

Although having weakened significantly by the time it reached the state, the slow movement of Hurricane Barry over Arkansas led to a widespread and significant flooding event. Murfreesboro saw the greatest rainfall accumulation at 14.58 inches (370.3 mm), which is the highest total ever recorded from a tropical cyclone in the state of Arkansas. [19]

The heaviest rainfall to occur in 24 hours was measured in Yankeetown during Hurricane Easy in 1950, which caused 38.70 inches (983 mm) of precipitation. This is also the highest known point storm total maximum related to any tropical cyclone which has impacted Florida, [1] 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. [34]

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 52 inches (1,300 mm) of rainfall reported. [3] This was the most rainfall reported to have been produced by a tropical cyclone within the United States until surpassed by Hurricane Harvey in 2017. [1]

Hurricane Audrey directed moisture up to a front to its north across the Midwest during late June 1957 as it transitioned into an extratropical cyclone. Heavy rains fell across central Illinois, leading to the wettest known event to be associated with a tropical cyclone or its remnants across Illinois.

Soon after moving inland, the 1960 Texas tropical storm 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). [68]

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 in 2001, Tropical Storm Frances in 1998, Tropical Storm Allison in 1989, and Tropical Storm Claudette in 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 than it currently does. [70]

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. [72] [73] Flooding caused by Hurricane Irene's heavy rainfall washed out two bridges on State Route 27 in Carrabassett Valley. [74]

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, 5 inches (130 mm) of rain were reported, while New York and Pennsylvania experienced 10 inches (250 mm). Westminster, Maryland received the maximum amount from the storm in this region with a total of 14.23 inches (361 mm).

Remnant tropical cyclones can move into the state which originate in either the Pacific or Atlantic hurricane basins. Tropical Storm Erin 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 10 inches (250 mm) in isolated spots, which became the wettest tropical cyclone remnant on record for the state.

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. [90] Over the past 30 years, the wettest tropical cyclone to strike the coastal plain was Hurricane Florence of September 2018, which dropped over 35 inches (890 mm) of rainfall in Elizabethtown. In the mountains, Hurricane Helene of September 2024 was the wettest, bringing over 30 inches (760 mm) of rainfall to Busick, which is the settlement closest to Mount Mitchell. [6]

Remnant tropical cyclones can move into the state which originate in either the Pacific or Atlantic hurricane basins. In 2007, Tropical Storm Erin reintensified over Oklahoma leading to heavy rainfall within the state. Rainfall exceeded 12 inches (300 mm) in isolated spots, which turned out to be the fourth wettest tropical cyclone remnant on record for Oklahoma. [8] [82]

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 6 to 12 inches (150 to 300 mm) with local amounts up to 19 inches (480 mm) in western Schuylkill County in Pennsylvania. [1] 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 has seen dramatic rainfall from tropical cyclones and their precursor disturbances. The most recent tropical cyclone-related deluge was from Hurricane Irene in August 2011, when 22.05 inches (560 mm) of rain was measured at Gurabo Abajo. [106] The heaviest rainfall noted over the past 30 years was from the precursor disturbance to Tropical Storm Isabel, when 31.67 inches (804 mm) fell at Toro Negro Forest. [107] Hurricane Eloise of 1975 dropped 33.29 inches (846 mm) of rainfall at Dos Bocas, with 23.07 inches (586 mm) falling in 24 hours.

Portions of South Carolina experienced significant rainfall totals eclipsing 35 inches (890 mm) with Hurricane Florence, which became the wettest known tropical cyclone to impact the state. The flash flooding covered numerous roadways and washed out bridges. River flooding was great across the state. In addition, the rainfall broke dams, flooded houses, and covered fields.

The most serious threat from tropical cyclones in Texas residents is from flooding, from both Gulf of Mexico hurricanes and tropical storms and the remnants of Eastern Pacific storms. Systems with sprawling circulations, such as Hurricane Beulah, also tend to make good rainmakers. [119] Slow moving systems, such as Tropical Storm Amelia or Hurricane Harvey also can produce significant rainfall over Texas. Harvey's storm total rainfall is the most recorded within the United States. [120] [121] Harvey's extremely heavy rainfall produced catastrophic flooding across much of southeastern Texas; particularly in and around the Houston metropolitan area, where accumulations exceeded 40 in (1,000 mm) over a four-day period. [120] Tropical Storm Claudette holds the national 24-hour rainfall record for the United States, with 42 inches (1,100 mm) falling within a day. [122]

Virginia has some special considerations that affect tropical cyclone-related rainfall. Mountains to the west act as a perfect mechanism for upward motion during sustained east winds, which can lead to flash flooding and landslides in that region (e.g. Hurricane Camille). As a tropical system approaches from the south, a frontal zone sets up between the moist Atlantic Ocean and the drier landmass to the west. This boundary can set up two or three days in advance of a tropical storm, and can lead up to prolonged heavy rains across coastal sections (e.g. Hurricane Floyd). As the cyclone advances north, the boundary will slowly shift west, but progresses west of a Richmond/Washington, D.C. line. [127]

The 1960 Atlantic hurricane season was the least active season since 1952. The season officially began on June 15, and lasted until November 15. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. The first system, an unnamed storm, developed in the Bay of Campeche on June 22. It brought severe local flooding to southeastern Texas and was considered the worst disaster in some towns since a Hurricane in 1945. The unnamed storm moved across the United States for almost a week before dissipating on June 29. In July, Hurricane Abby resulted in minor damage in the Leeward Islands, before impacting a few Central American counties — the remnants of the storm would go on to form Hurricane Celeste in the East Pacific. Later that month, Tropical Storm Brenda caused flooding across much of the East Coast of the United States. The next storm, Hurricane Cleo, caused no known impact, despite its close proximity to land.
Hurricane Kathleen was a Category 1 Pacific hurricane that had a destructive impact in California. On September 7, 1976, a tropical depression formed; two days later it accelerated north towards the Baja California Peninsula. Kathleen brushed the Pacific coast of the peninsula as a hurricane on September 9 and made landfall as a fast-moving tropical storm the next day. With its circulation intact and still a tropical storm, Kathleen headed north into the United States and affected California and Arizona. Kathleen finally dissipated late on September 11.
Tropical Storm Frances caused extensive flooding in Mexico and Texas in September 1998. The sixth tropical cyclone and sixth named storm of the annual hurricane season, Frances developed from a low pressure area in the Gulf of Mexico on September 8. The cyclone moved northward through the western Gulf of Mexico, making landfall across the central Texas coastline before recurving across the Midwest through southeast Canada and New England. A large tropical cyclone for the Atlantic basin, yet an average sized system by western Pacific standards, the storm produced heavy rains across the Isthmus of Tehuantepec, Texas, western Louisiana and the Great Plains.
Tropical Storm Arlene brought torrential rainfall to the western United States Gulf Coast, particularly to the U.S. state of Texas, in June 1993. The first named storm of the 1993 Atlantic hurricane season, Arlene developed from an area of low pressure in the Bay of Campeche on June 18. The depression slowly strengthened as it tracked west-northwestward and later north-northwestward across the western Gulf of Mexico. Arlene was subsequently upgraded to a tropical storm on June 19, but failed to intensify further due to its proximity to land. The cyclone then made landfall on Padre Island, Texas, with winds of 40 mph (65 km/h) and degenerated into a remnant disturbance on June 21.
The United States tropical cyclone rainfall climatology concerns the amount of precipitation, primarily in the form of rain, which occurs during tropical cyclones and their extratropical cyclone remnants across the United States. Typically, five tropical cyclones and their remnants impact the country each year, contributing between a tenth and a quarter of the annual rainfall across the southern tier of the country. The highest rainfall amounts appear close to the coast, with lesser amounts falling farther inland. Obstructions to the precipitation pattern, such as the Appalachian Mountains, focus higher amounts from northern Georgia through New England. While most impacts occur with systems moving in from the Atlantic Ocean or Gulf of Mexico, some emanate from the eastern Pacific Ocean, with a few crossing Mexico before impacting the Southwest. Those making landfall within the Southeast portion of the country tend to have the greatest potential for heavy rains.
Mexico tropical cyclone rainfall climatology discusses precipitation characteristics of tropical cyclones that have struck Mexico over the years. One-third of the annual rainfall received along the Mexican Riviera and up to half of the rainfall received in Baja California Sur is directly attributable to tropical cyclones moving up the west coast of Mexico. The central plateau is shielded from the high rainfall amounts seen on the oceanward slopes of the Sierra Madre Oriental and Occidental mountain chains.
Hurricane Paine was the sixteenth tropical storm and eighth hurricane of the fairly active 1986 Pacific hurricane season; moisture from the system contributed to one of the most significant flooding events in Oklahoma history. Paine formed on September 28 off the southeast coast of Mexico. It moved around a ridge, later turning to the north and brushing the Baja California Peninsula. By that time, Paine had attained peak winds of 100 mph (160 km/h), but it weakened slightly before hitting the Mexican state of Sonora. The remnant moisture combined with a cold front to produce heavy rainfall in the South Central United States.
Hurricane Hiki was the third-wettest tropical cyclone on record in the United States, behind Hurricane Lane in 2018, and Hurricane Harvey in 2017. It was also considered the first official hurricane in the vicinity of the Hawaiian Islands. The fourth tropical cyclone of the 1950 Pacific hurricane season, Hiki formed as a tropical depression to the southeast of Hawaii on August 12. On the following day, the depression headed northwestward and intensified into Tropical Storm Hiki. While paralleling the Hawaiian Islands on August 16, Hiki strengthened into a hurricane. Around that time, the storm peaked with maximum sustained winds of 85 mph (140 km/h). The following day, Hiki curved southwestward on August 17. Two days later, the hurricane resumed moving northwestward and weakened to a tropical storm shortly thereafter. Around midday on August 21, Hiki weakened to a tropical depression and dissipated about six hours later.
The 1960 Texas tropical storm brought severe but localized flooding to southeastern Texas in June 1960. The first tropical cyclone and first tropical storm of the 1960 Atlantic hurricane season, this system developed from an area of showers and thunderstorms in the Bay of Campeche on June 22. Initially a tropical depression, it strengthened and was estimated to have reached tropical storm status on June 23. Early on the following day, the storm peaked with winds of 60 mph (97 km/h). Later that day, it made landfall near Corpus Christi, Texas, at the same intensity. The storm weakened slowly and moved across the Central United States, before dissipating over Illinois on June 28.
Tropical Storm Imelda was a tropical cyclone which was the fourth-wettest storm on record in the U.S. state of Texas, causing devastating and record-breaking floods in southeast Texas. The eleventh tropical cyclone and ninth named storm of the 2019 Atlantic hurricane season, Imelda formed out of an upper-level low that developed in the Gulf of Mexico and moved westward. Little development occurred until the system was near the Texas coastline, where it rapidly developed into a tropical storm before moving ashore shortly afterward on September 17. Imelda weakened after landfall, but continued bringing large amounts of flooding rain to Texas and Louisiana, before dissipating on September 21.
