[[Image:Hilary 2023-08-20 1730Z.jpg|thumb|Satellite image of dissipating [[Hurricane Hilary]] in August 2023, which caused damaging floods across the state|230px|right]]<onlyinclude><!-- See [[Wikipedia_talk:Featured_lists#Proposed_change_to_all_featured_lists]] for an explanation of this and other inclusion tags below -->Since 1854, at least 100&nbsp;[[tropical cyclone]]s affected the [[U.S. state]] of [[California]], including [[1858 San Diego hurricane|a hurricane in 1858]] that produced hurricane-force winds near [[San Diego]]. This averages to roughly once a year, although events are more likely during [[El Niño–Southern Oscillation|El Niño]] events. Although storms have occurred as early as June and as late as October, they are most likely during the month of September. Due to cold [[sea surface temperature]]s and the typical track of most [[Pacific hurricane]]s, there has only been one recorded [[landfall (meteorology)|landfall]] of a tropical storm in the state &ndash; [[1939 California tropical storm|a storm in 1939]] that hit [[Los Angeles]], killing 45&nbsp;people after catching many residents off guard. There have been at least 13&nbsp;other deadly tropical cyclones affecting California.</onlyinclude>

Typically, the greatest threat to California from tropical cyclones is rainfall, which can cause [[flash flood]]ing when the precipitation accumulates quickly enough. Former [[Hurricane Kathleen (1976)|Hurricane Kathleen]] in 1976 produced {{convert|14.76|in|mm}} of rainfall along [[Mount San Gorgonio]], which was the highest precipitation in California related to an Atlantic or Pacific hurricane. Kathleen killed at least nine people in the state from heavy rainfall, with severe flooding affecting the city of [[Ocotillo, California|Ocotillo]]. On some occasions, tropical cyclones have dropped the equivalent to a year's worth of rainfall, particularly in the deserts of southern California. 

California occasionally experiences high surf and [[rip current]]s from distant but powerful hurricanes, such as [[Hurricane Guillermo (1997)|Hurricane Guillermo]] in 1997, which killed a swimmer in [[Orange County, California|Orange County]]. Although the state does not usually suffer from high winds, there have been eight tropical cyclones that have brought [[gale]]-force winds to California since 1850, including the hurricane of 1858 and the 1939 tropical storm. Those include the remnants of [[Tropical Storm Jennifer-Katherine (1963)|Tropical Storm Jennifer-Katherine]] in 1963, [[Hurricane Emily (1965)|Hurricane Emily]] in 1965, and [[Hurricane Joanne (1972)|Hurricane Joanne]] in 1972. [[Hurricane Nora (1997)|Tropical Storm Nora]] in 1997 entered the state, producing gale-force winds and heavy rainfall that led to four traffic deaths. The remnants of [[Hurricane Kay (2022)|Hurricane Kay]] in 2022 produced flooding and {{cvt|100|mph}} wind gusts across southern California, killing one person. In August 2023, the remnants of [[Hurricane Hilary]] produced {{cvt|87|mph|km/h}} winds along with heavy rainfall, with floods killing one person.

==Climatology and warnings==
[[Image:CaliforniaTropicalCycloneBreakpoints.png|thumb|right|Map of warning breakpoints]]
The state of California rarely experiences [[Pacific hurricane]]s for various reasons. Typically, storms in the region move to the west or northwest, away from the North American mainland and out to sea. In addition, much of the coast of California experiences cold [[sea surface temperature]]s due to the [[California Current]]. As a result, the temperatures in the summer rarely rise above 24&nbsp;°C (75&nbsp;°F) in southern California, too cold to sustain intense tropical cyclones, and much cooler than the same latitude along the United States Atlantic coastline.<ref>{{cite web|url=https://www.aoml.noaa.gov/hrd-faq/#west-coast-hurricanes|title=Hurricanes Frequently Asked Questions|date=June 1, 2023|publisher=National Oceanic and Atmospheric Administration|access-date=May 18, 2024|archive-date=September 1, 2023|archive-url=https://web.archive.org/web/20230901040902/https://www.aoml.noaa.gov/hrd-faq/#west-coast-hurricanes|url-status=live}}</ref> Consequently, the primary threat from tropical cyclones in the region is not from winds, but from rainfall and [[flash flood]]s. Occasionally, these storms enter southern California after making [[landfall (meteorology)|landfall]] along Mexico's [[Baja California peninsula]], or otherwise in their dissipating stage. In other instances, an mid-latitude [[trough (meteorology)|trough]] can draw moisture from a distant tropical cyclone. Northern California is rarely affected by tropical cyclones.<ref name="tm258">{{cite report|title=1985 - 1998 Eastern North Pacific Tropical Cyclones Impacting the Southwest United States and Northern Mexico: An Updated Climatology|date=January 1999|author=Armando L.

Roughly once a year, tropical cyclones affect the southwestern United States.<ref name="tm258"/> The frequency of events increases during [[El Niño–Southern Oscillation|El Niño]] events, such as 1932, 1939, 1972, 1976, 1982, 1997, 2015, and 2023 A record four tropical cyclones affected the state in September 1939, which set monthly precipitation records across the region.

Until around 1920, the [[United States Weather Bureau]] did not acknowledge the eastern Pacific Ocean as a [[tropical cyclone basin]]. After the unexpected [[1939 California tropical storm|1939 Long Beach tropical storm]], the weather bureau set up a forecast office for southern California in February 1940. Before 1965, the lack of satellite imagery meant that some tropical cyclones that affected the region were undetected.<ref name="Smith"/><ref name="nws"/> In the event a tropical cyclone threatens the state, the [[National Hurricane Center]] (NHC) issues a variety of advisories and bulletins, including [[tropical cyclone warnings and watches]]. The NHC can issue these advisories at one of seven locations along the Pacific coast, known as breakpoints, beginning at the [[Mexico–United States border]], and continuing northward to [[Piedras Blancas Light Station|Point Piedras Blancas]].<ref>{{cite web|title=Hurricane and Tropical Storm Watch/Warning Breakpoints|url=https://www.nhc.noaa.gov/breakpoints/|date=March 2024|accessdate=May 29, 2024|publisher=National Hurricane Center|archive-date=May 15, 2024|archive-url=https://web.archive.org/web/20240515224549/https://www.nhc.noaa.gov/breakpoints/|url-status=live}}</ref> The first ever tropical storm watch or warning for the state was in 2023 during [[Hurricane Hilary]].<ref name="htcr"/>

==List of tropical cyclones==
Hurricanes that affect California are mainly the remnants of hurricanes or tropical storms. In the twentieth century, only four eastern Pacific tropical cyclones have brought tropical storm-force winds to the [[Continental United States]]: the [[1939 Long Beach Tropical Storm]], [[Hurricane Joanne (1972)|Tropical Storm Joanne]] in 1972, [[Hurricane Kathleen (1976)|Tropical Storm Kathleen]] in 1976, and [[Hurricane Nora (1997)|Tropical Storm Nora]] in 1997.<ref name="sandiegohurricane">{{cite web|url=http://www.aoml.noaa.gov/hrd/Landsea/chenowethlandsea.pdf|title=The San Diego Hurricane of October 2, 1858|author=[[Christopher Landsea]] & Michael Chenoweth|publisher=[[American Meteorological Society]]|work=[[Bulletin of the American Meteorological Society]]|pages=1689|date=November 2004|access-date=2007-12-26|archive-date=2012-09-04|archive-url=https://web.archive.org/web/20120904191216/http://www.aoml.noaa.gov/hrd/Landsea/chenowethlandsea.pdf|url-status=live}}</ref>
