- List of wettest tropical cyclones in the United States
This list of wettest tropical cyclones in the United States presents the highest known rainfall totals from
tropical cyclone s and their remnants. These storms have moved into the lower 48United States from theAtlantic Ocean , theGulf of Mexico , and the easternPacific Ocean . The tropical cyclones and their remnants which have brought rainfall toAlaska ,Puerto Rico , theU.S. Virgin Islands ,Hawaii ,Guam , andAmerican Samoa are also included within this list.Alabama
The wettest tropical cyclone to impact the state of
Alabama was Hurricane Danny, which stalled overMobile Bay for over 24 hours, and which led to significant rainfall. [cite web|author=David M. Roth |url=http://www.hpc.ncep.noaa.gov/tropical/rain/danny1997.html|title=Hurricane Danny Rainfall Page|accessdate=2008-03-04]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. [cite web|publisher=

The wettest known tropical cyclone to impact
New England is also the wettest known for the state of Connecticut. The flood fromHurricane Diane led to a significant death toll (nearly 200) from Pennsylvania eastward through southern New England.cite web|url=http://www.hpc.ncep.noaa.gov/tropical/rain/diane1955.html|author=David M.

Tropical Storm Alberto in 1994 looped across central Georgia, leading to 24-hour rainfall amounts exceeding convert|20|in|mm across central sections of the state. [cite web|author=

Impacts from tropical cyclones in the
Pacific Northwest are rare. Most recently, the remains of Olivia moved through the region in 1982, spurring spotty moderate to heavy rainfall acrossIdaho .Iowa
Hurricane Carla was a large hurricane which moved into Texas during September 1961. As it transitioned into anextratropical cyclone across theGreat 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 acrossIowa .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) , andTropical Storm Claudette (1979) . Three of the four systems stalled across eastern Texas, prolonging the rainfall which occurred overLouisiana . 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.

The wettest known tropical cyclone to impact
New England is also the wettest known for the state ofMassachusetts .

Hurricane Georges stalled over the southern portion of the state, it produced torrential rainfall, exceeding convert|30|in|mm locally.cite web|author=David M. Roth |url=http://www.hpc.ncep.noaa.gov/tropical/rain/georges1998.html|title=Hurricane Georges Rainfall Page|accessdate=2008-03-06] The heavy rainfall contributed to significant river overflowing, including the Tchoutacabouffa River at D'Iberville, which set a record crest of convert|19|ft|m.

Hurricane Carla was a large hurricane which moved into Texas during September 1961. As it transitioned into anextratropical cyclone across theGreat 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 acrossNebraska .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 ,David M. Roth . [http://www.hpc.ncep.noaa.gov/tropical/rain/floyd1999.html Hurricane Floyd - September 14-17, 1999.] Retrieved on2008-03-06 .] which produced over convert|14|in|mm across portions ofNew Jersey .North Carolina
Heavy rains accompany
tropical cyclones and their remnants which move northeast from theGulf of Mexico coastline, as well as inland from the western subtropicalAtlantic ocean . As much as 15% of the rainfall which occurs during the warm season in the Carolinas is attributable to tropical cyclones. [cite web|author=David B. Knight and Robert E. Davis|url=http://bellwether.metapress.com/content/n562284522t561n5/|title=Climatology of Tropical Cyclone Rainfall in the Southeastern United States|accessdate=2008-02-29] Over the past 30 years, the wettest tropical cyclone to strike the coastal plain wasHurricane Floyd of September 1999, which dropped over convert|24|in|mm of rainfall north of Southport. In the mountains,Hurricane Frances of September 2004 was nearly as wet, bringing over convert|23|in|mm of rainfall toMount Mitchell .cite web|author=David M. Roth |url=http://www.hpc.ncep.noaa.gov/tropical/rain/tcsoutheast.html|title=Tropical Cyclone Rainfall in the Southeast|accessdate=2007-12-20]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 theGulf of Mexico .Hurricane Frederic in 1979, interacting with a nearby frontal zone, [cite web|publisher=National Weather Service |url=http://docs.lib.noaa.gov/rescue/dwm/data_rescue_daily_weather_maps.html|title=Daily Weather Maps: September 10-16, 1979|accessdate=2008-03-06] brought over convert|8|in|mm of rainfall to isolated spots of the state, becoming the wettest known tropical cyclone, or remnant, to impact Ohio.Pennsylvania
Although
Hurricane Agnes was barely a hurricane at landfall inFlorida , its major impact was over the Mid-Atlantic region, where Agnes combined with a non-tropical low to produce widespread rains of convert|6|in|mm to convert|12|in|mm with local amounts up to convert|19|in|mm in western Schuylkill County inPennsylvania . These rains produced widespread severe flooding fromVirginia northward to New York, with other flooding occurring over the western portions of the Carolinas.outh Carolina
Portions of
South Carolina experienced significant rainfall totals approaching convert|19|in|mm withTropical Storm Jerry (1995) , which became the wettest known tropical cyclone to impact the state. [cite web|author=David M. Roth |url=http://www.hpc.ncep.noaa.gov/tropical/rain/jerry1995.html|title=Tropical Storm Jerry Rainfall Page|accessdate=2008-03-06] 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). [cite web|author=Richard J. Pasch|url=http://www.nhc.noaa.gov/1995jerry.html|title=Preliminary Report: Tropical Storm Jerry 22-28 August 1995|accessdate=2008-03-06]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. [cite web|author=David M. Roth |url=http://www.srh.noaa.gov/lch/research/txhuclimo2.php|title=A Brief Climatology of Tropical Cyclones in Texas (continued)|accessdate=2008-03-05] Slow moving systems, such asTropical 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. [cite web|author=David M.
