[[Arizona]] has been affected by [[tropical cyclone|hurricanes]] on numerous occasions. Usually, these storms originate in the [[Tropical cyclone basins#Northeast Pacific Ocean|eastern Pacific Ocean]], make landfall in the Mexican states of [[Baja California]] or [[Sonora]], and dissipate before crossing into the United States. Thus, in most cases, it is only the tropical cyclones' remnant moisture that produces heavy rainfall—and in some occasions, flooding—in portions of Arizona. However, approximately every five years, a tropical cyclone retains sufficient strength to enter the state as a [[Tropical cyclone#Intensities of tropical cyclones|tropical storm]] or a [[tropical depression]]. Arizonans can expect indirect [[flash flood]]s caused by the remnants of tropical cyclones to occur about every two years.<ref name="NWS Tucson"/>

Tropical cyclones in Arizona are not common, since the [[Trade wind|predominant wind pattern]] steers most storms that form in the Eastern Pacific either parallel or away from the Pacific coast of northwestern Mexico. As a result, most storms that could affect Arizona are carried away from the United States, with only 6% of all Pacific hurricanes entering US territory.<ref name="monsoon">{{cite web|first=Kristen L.|last=Corbosiero|title=The Contribution of Eastern North Pacific Tropical Cyclones to the Warm Season Rainfall Climatology of the Southwestern United States|year=2003|publisher=[[University of Albany]]|access-date=2011-07-23|url=http://www.atmos.ucla.edu/~kristen/monsoon/monsoon.html |archive-url = https://web.archive.org/web/20060505070334/http://www.atmos.albany.edu/student/kristen/monsoon.html |archive-date = 2006-05-05 |url-status=dead}}</ref> Not all Arizona hurricanes originate from the Pacific Ocean, however; in July 2008, an [[Atlantic hurricane]] named [[Hurricane Dolly (2008)|Hurricane Dolly]] produced rainfall in the eastern portion of the state, and another Atlantic storm reached Arizona as a tropical depression. Many, but not all, of these systems also [[List of California tropical storms|impacted California]].

Despite their rarity, tropical cyclones are among Arizona's most significant weather makers. In years when Arizona is affected by a tropical cyclone, these can be responsible for up to 25% of the rainfall in areas along the [[Colorado River]]. Arizona hurricanes are also responsible for torrential rains in localized areas, with the state's 24-hour rainfall record—{{convert|11.97|in|mm}} of precipitation<ref name="MCFCD"/>—occurring during [[Hurricane Nora (1997)|Hurricane Nora]]'s [[landfall]] in 1997. The heavy rainfall can trigger extensive flash floods, such as the ones produced by the remnants of [[October 1983 Southwest United States floods|Tropical Storm Octave]] in 1983, or the lingering moisture from [[Tropical Storm Emilia (2006)|Tropical Storm Emilia]] in 2006.

==Climatology==
{{Wettest tropical cyclones in Arizona|align=right}}
Tropical cyclones are not common over Arizona, but on average, a tropical storm or a tropical depression affects the state approximately every five years. However, indirect [[flash flood]]s caused by the remnants of tropical cyclones are more common, as they tend to occur about every two years.<ref name="NWS Tucson">{{cite web|author=National Weather Service, Tucson Regional Office|title=Tropical cyclones in Arizona|access-date=2011-07-21|url=http://www.wrh.noaa.gov/twc/tropical/tropical.php|archive-url=https://web.archive.org/web/20111014025624/http://www.wrh.noaa.gov/twc/tropical/tropical.php|archive-date=2011-10-14|url-status=live}}</ref>

Storms that approach the southwestern United States, specifically Arizona, generally track closer to the Mexican coast than average, making them more likely to recurve northwards under the influence of an approaching [[trough (meteorology)|trough]]. These troughs tend to extend farther to the south during the latter part of the Pacific hurricane season, in the period between late August and early October. These pronounced troughs thus produce a [[synoptic scale|synoptic-scale]] flow that is conducive to steering hurricanes towards the southwestern United States.<ref name="Corbosiero MWR">{{cite journal|last=Corbosiero|first=Kristen L.|author2=Dickinson, Michael J. |author3=Bosart, Lance F. |title=The Contribution of Eastern North Pacific Tropical Cyclones to the Rainfall Climatology of the Southwest United States|journal=[[Monthly Weather Review]]|date=August 2009|volume=137|issue=8|pages=2415–2435|doi=10.1175/2009MWR2768.1|bibcode = 2009MWRv..137.2415C |doi-access=free}}</ref> All of the systems that have impacted Arizona have formed in the [[Pacific hurricane season]], and only storm remnants have affected the state before August.<ref name="monsoon"/>

The infusions of tropical moisture from tropical cyclones can be a significant portion of the annual rainfall in the region. In years when storms approach Arizona, eastern and northern portions of the state receive on average 6–8% of the [[North American Monsoon|monsoon-season]] precipitation from tropical systems and their remnants. This percentage rises towards the southwestern corner of the state, which can receive up to a quarter of its monsoon-season rainfall from tropical cyclones.<ref name="Corbosiero MWR"/><ref name="USGS">{{cite web | title=Hydrologic Conditions in Arizona During 1999–2004: A Historical Perspective | publisher=[[United States Geological Survey]] | author=Arizona Water Science Center | access-date=2006-03-20 | date=September 2005 | url=http://pubs.usgs.gov/fs/2005/3081/pdf/FS2005-3081WEB.pdf | archive-date=2011-11-04 | archive-url=https://web.archive.org/web/20111104221230/http://pubs.usgs.gov/fs/2005/3081/pdf/FS2005-3081WEB.pdf | url-status=live }}</ref>

===Before 1960===
Records of [[Pacific hurricane|tropical cyclones in the East Pacific]] before 1950 are sparse, but there were still several storms that produced rainfall over Arizona in this period.
*August 1921:  The first known tropical disturbance to affect the state occurred when a remnant low of a tropical cyclone moved into the western portions of the state.<ref name="USA Today California">{{cite news | author = Williams, Jack | url = https://www.usatoday.com/weather/whhcalif.htm | title = Background: California's tropical storms | date = May 17, 2005 | newspaper = [[USA Today]] | access-date = 2008-05-16 | archive-url = https://web.archive.org/web/20090226172558/http://www.usatoday.com/weather/whhcalif.htm | archive-date = February 26, 2009 | url-status = live }}</ref>

* September 1926: Five years later, the remnants of another September storm hit the state, but this time the precipitation was heaviest on the southeastern portion of the state. The 1926 storm caused over {{convert|5.00|in|mm}} of rain in the vicinity of [[Douglas, Arizona|Douglas]].<ref name="NWS Phoenix"/>
* September 1927: The remnants of another tropical system caused {{convert|1|–|2|in|mm}} of rainfall throughout the state.<ref name="NWS Phoenix"/>
* June 1929: The [[Atlantic hurricane reanalysis]] project discovered that a rare [[North Atlantic tropical cyclone|Atlantic hurricane]] reached the eastern part of the state as a tropical depression.{{hurdat-ATL}}<ref>{{cite web|last=Christopher W.

* August 1935: The remnants of an unnamed tropical storm that landed on Southern California caused torrential rain and flooding across Arizona, especially along the [[Santa Cruz River (Arizona)|Santa Cruz River]] and Rillito Creek on Southern Arizona. The rainfall from the storm contributed to an extremely wet month of August, which still holds the monthly rainfall record at the National Weather Service office in Tucson, as {{convert|5.61|in|mm}} of rainfall fell during the month.<ref name="USACE Pima"/>
* September 1939: Two tropical systems entered the state during the month. On September 4, the remnants of a former hurricane entered southwest Arizona, near Yuma. More than {{convert|5.00|in|mm}} of precipitation fell in northwest Arizona, with many parts of the state collecting more than an inch of rain.<ref name="NWS Phoenix"/> This same system produced more than twice the average annual rainfall in [[Imperial Valley (California)|Imperial Valley, California]].<ref name="USA Today California"/> On the 11th, the remnants of a separate system also passed over southwest Arizona.<ref name="USA Today California"/>
*August 1951: No tropical cyclones are known to have affected Arizona in the 1940s. However, in the 1950s, the remnants of two more storms affected the state. On August 24, 1951, the moisture from a hurricane that made landfall in [[Baja California]] moved over the state, producing more than {{convert|5.00|in|mm}} of precipitation over southwestern Arizona. Flagstaff saw {{convert|4.00|in|mm}} of rain, with similar totals measured at Prescott ({{convert|3.95|in|mm|disp=x|; }}) and Phoenix ({{convert|3.24|in|mm|disp=x|; }}). The storm also washed out several roadways near [[Gila Bend, Arizona|Gila Bend]], isolating the city from motorists. Overall, the storm caused $750,000 (1951 [[USD]]) in property damage.<ref name="NWS Phoenix"/>
*July 1954: Three years later, the remnants of another hurricane moved over Arizona from the south during the month of July. Damage from this storm is unknown.<ref name="USA Today California"/>

===1960s===
* September 1962: Remnant moisture from [[Tropical Storm Claudia (1962)|Tropical Storm Claudia]] caused severe flash floods in the vicinity of Tucson, with {{convert|5|to|7|in|mm}} of precipitation falling over the headwaters of the [[Arroyo (watercourse)|washes]] of Santa Rosa, Jackrabbit, and [[Brawley Wash|Brawley]] during a 14- to 15-hour period.<ref name="USACE Pima" /> Over {{convert|7|in|mm}} of rainfall also fell near the [[Arizona-Sonora Desert Museum]].<ref name="NWS Phoenix"/> The ensuing flood of the [[Santa Cruz River (Arizona)|Santa Cruz River]] and its tributaries produced a path of destruction about {{convert|100|mi|km}} long and up to {{convert|8|mi|km}} wide. Santa Rosa Wash conveyed {{convert|53100|cuft/s|m3/s|lk=on}} at its peak; Los Robles Wash carried up to {{convert|32600|cuft/s|m3/s|abbr=on}}, while the Santa Cruz River proper peaked at {{convert|9200|cuft/s|m3/s|abbr=on}}. The washes and rivers reached depths of up to {{convert|20|ft|m}}, and overflowed its banks in places by {{convert|1|to|6|ft|m}}.<ref name="USACE Pima" /> Flooding from the storm inundated the towns of [[Marana, Arizona|Marana]] and [[Sells, Arizona|Sells]], both in [[Pima County, Arizona|Pima County]].<ref name="NWS Phoenix"/> Total damage in Pima and [[Pinal County, Arizona|Pinal]] Counties exceeded $11 million (1962 USD).<ref name="USACE Pima" />
* September 1964: The next storm to affect the state was [[Tropical Storm Tillie (1964)|Tropical Storm Tillie]] in 1964. Although the storm remained at sea,<ref name="NOAA CSC"/> its residual moisture was advected over southern Arizona, allowing a passing [[cold front]] to trigger widespread showers and thunderstorms on the evening of September 9.<ref name="USACE Pima" /> Tucson received {{convert|3.05|in|mm}} of rainfall in a 24-hour period between September 9 and 10,<ref>{{cite journal|last=Green|first=Raymond, A.|title=The Weather and Circulation of September 1964|journal=Monthly Weather Review|date=December 1964|volume=92|issue=12|pages=601–606|doi=10.1175/1520-0493(1964)092<0601:TWACOS>2.3.CO;2|bibcode = 1964MWRv...92..601G |doi-access=free}}</ref> and two locations—one in the [[Catalina Mountains|Catalina Mountain foothills]] and one near [[Sahuarita, Arizona|Sahuarita]]—recorded {{convert|6.75|in|mm}} of precipitation.

* September 1965: The following year, the remnants of [[Hurricane Emily (1965)|Hurricane Emily]] crossed into Arizona from Baja California.<ref name="NOAA CSC"/> Any damage from the storm is not known.
* September 1966: The remnants of [[Tropical Storm Kirsten (1966)|Kirsten]] caused {{convert|1.26|in|mm}} of rainfall in [[Nogales, Arizona|Nogales]].<ref name="NWS Tucson-Kirsten">{{cite web|author=National Weather Service, Tucson Regional Office|title=Hurricane Kirsten 1966|access-date=2011-07-21|url=http://www.wrh.noaa.gov/twc/tropical/kirsten_1966.htm|archive-url=https://web.archive.org/web/20170616001944/http://www.wrh.noaa.gov/twc/tropical/kirsten_1966.htm|archive-date=2017-06-16|url-status=live}}</ref>

* August 1968: Two storms approached Arizona in 1968. The first was [[Tropical Storm Hyacinth (1968)|Tropical Storm Hyacinth]] in August. It reached the southeastern corner of the state as a tropical depression,<ref name="NOAA CSC"/> and produced showers and thunderstorms over the eastern portion of the state.<ref>{{cite journal|last=Denney|first=William J.|title=The Eastern Pacific Hurricane Season of 1968|journal=Monthly Weather Review|date=March 1969|volume=97|issue=3|pages=207–224|doi=10.1175/1520-0493(1969)097<0207:TEPHSO>2.3.CO;2|bibcode = 1969MWRv...97..207D |s2cid=120697651 |doi-access=free}}</ref>
* October 1968: The last storm to impact Arizona during the decade was [[Hurricane Pauline (1968)|Hurricane Pauline]], which added high amounts of moisture ahead of a cold front in early October. The added [[atmospheric instability|instability]] in the atmosphere allowed the cold front to produce [[severe thunderstorm]]s, including an [[Fujita scale|F2 tornado]] that wrecked several homes and caused $250,000 (1968 USD) in damage when it touched down in [[Glendale, Arizona|Glendale]].<ref name="NWS Tucson-Pauline">{{cite web|author=National Weather Service, Tucson Regional Office|title=Hurricane Pauline 1968|access-date=2011-07-21|url=http://www.wrh.noaa.gov/twc/tropical/pauline_1968.htm|archive-url=https://web.archive.org/web/20120320072045/http://www.wrh.noaa.gov/twc/tropical/pauline_1968.htm|archive-date=2012-03-20|url-status=live}}</ref><ref>{{cite web|title=Event Report for Arizona: Maricopa County|url=http://www4.ncdc.noaa.gov/cgi-win/wwcgi.dll?wwevent~ShowEvent~5557|publisher=National Climatic Data Center|access-date=2011-07-21|year=1968}}{{dead link|date=April 2018 |bot=InternetArchiveBot |fix-attempted=yes }}</ref>
