/* An improbable event */ (1858 shows that it is possible, though rare)
<onlyinclude><!-- See [[Wikipedia_talk:Featured_lists#Proposed_change_to_all_featured_lists]] for an explanation of this and other inclusion tags below -->A '''California hurricane''' is a [[tropical cyclone]] that affects the state of [[California]]. Usually, only the remnants of tropical cyclones affect California. No hurricane has ever made landfall in California in recorded history. Two tropical storms have hit California, one by direct landfall from offshore, another after making landfall in [[Mexico]].</onlyinclude>
Since 1900, only four tropical cyclones have brought gale-force winds to the Southwestern United States. They are an unnamed tropical storm that made landfall near San Pedro in 1939, the remnants of Hurricane Joanne in 1972, the remnants of Hurricane Kathleen in 1976, and Hurricane Nora in 1997 which entered California as a tropical storm. In addition, a recently-discovered and reconstructed hurricane just missed making landfall in 1858.
In most cases, rainfall is the only effect that these cyclones have on California. Sometimes, this rainfall is severe enough to cause flooding and damage. For example, floods from Hurricane Kathleen devastated [[Ocotillo, California]] and killed several people. Precipitation other than rainfall is unusual<ref name="NHC Marilyn">{{cite web|url=http://www.nhc.noaa.gov/1995marilyn.html|title=Preliminary Report Hurricane Marilyn|author=[[Ed Rappaport]]|publisher=[[National Hurricane Center]]|date=1996-01-17|accessdate=2008-01-14}}</ref> in tropical cyclones because of their weak updrafts and lack of supercooled water.<ref name=C5A>{{cite web|url=http://www.aoml.noaa.gov/hrd/tcfaq/C5a.html|author=[[Chris Landsea]]|title=Subject: C5a) Why don't we try to destroy tropical cyclones by seeding them with silver iodide?|work=FAQ|accessdate=2008-01-14|publisher=[[National Hurricane Center]]}}</ref>

==An improbable event==
There are two reasons why tropical cyclones rarely strike California: sea surface temperatures, and the usual upper level steering winds in the eastern Pacific, with sea surface temperature being the most important.
Tropical cyclones usually require very warm water to depth, generally above 26.5 °C (80 °F) extending to a depth of 50 metres (160 ft).<ref name=A16>{{cite web | title=Subject: A16) Why do tropical cyclones require 80 °F (26.5 °C) ocean temperatures to form ? | work= Tropical Cyclone FAQ| url=http://www.aoml.noaa.gov/hrd/tcfaq/A16.html | accessdate=2007-12-25| author=[[Christopher Landsea]]|publisher=[[National Hurricane Center]]}}</ref>
The waters off California are cold even in summer. They rarely rise above 24 °C (75 °F) in near-shore southern California,<ref name=G8>{{cite web|url=http://www.aoml.noaa.gov/hrd/tcfaq/G9.html|title=Subject: G8) Why do hurricanes hit the East coast of the U.S., but never the West coast?|work=Tropical Cyclone FAQ|publisher=[[National Hurricane Center]]|author=[[Christopher Landsea]]|accessdate=2007-12-25}}</ref> and usually don't get above 17 °C (63 °F) along most of the rest of the coast and outer coastal waters, although [[El Niño]] events may warm the waters somewhat. This is due primarily to the extensive [[upwelling]] of colder sub-surface waters caused by the prevailing northwesterly winds acting through the [[Ekman spiral|Ekman Effect]]. The winds drive surface water to the right of the wind flow, that is offshore, which draws water up from below to replace it. The upwelling further cools the already cool [[California Current]] which runs north to south along coastal California and even much of coastal [[Baja California]]. This is the same mechanism which produces coastal California's characteristic fog.
The second reason is the general path of tropical cyclones in the eastern Pacific. They generally move north-westward or westward due to steering by the prevailing upper level winds, which takes them far out to sea and away from land.<ref name=G8/>
These factors make eastern Pacific landfalls improbable north of about central Baja California. In those instances when upper level steering winds do allow a more northerly path, much cooler sea surface temperatures quickly weaken tropical cyclones that approach California, although torrential rainfall can still occur. For example, the September 24-hour rainfall record for [[Los Angeles, California|Los Angeles]] is held by the [[1939 Long Beach Tropical Storm]], as of January 2007.<ref name="history of sig events p10">{{cite web|url=http://www.wrh.noaa.gov/sgx/research/Guide/weatherhistory.pdf|title=A History of Significant Weather Events in Southern California|format=PDF|pages=10|publisher=NOAA|accessdate=2007-12-26|month=January|year=2007}}</ref>
==List of cyclones==
Most of these cyclones 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]], [[1972 Pacific hurricane season#Hurricane Joanne|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 2 October 1858|author=[[Christopher Landsea]] & Michael Chenoweth|publisher=[[American Meteorological Society]]|work=[[Bulletin of the American Meteorological Society]]|pages=1689|month=November|format=PDF|year=2004|accessdate=2007-12-26}}</ref>

==Modern repeats==
While rare, tropical cyclones do affect California, occasionally very seriously as far as rainfall is concerned.
===Damage===
[[Image:CaliforniaTropicalCycloneBreakpoints.png|thumb|400px|right|Map of warning breakpoints]]
A modern repeat of the 1858 storm is estimated to cause damages of hundreds of millions of dollars.<ref name="sandiegohurricane"/> A repeat of the 1939 tropical storm would cause around 200 million dollars in damage.<ref name="sandiegohurricane"/> The most serious damage would be due to rains rather than winds or storm surge, although distant hurricanes may still create heavy surf,<ref name="nhclinda1997"/> possibly injuring or killing people. Nora caused millions in damage and skirted extreme southeastern California.
===Preparedness===
When Linda was forecast to make landfall, statements about its possible impact were issued by the [[Oxnard, California]] office of the [[National Weather Service]]. They stressed the uncertainty of a forecast that far in the future.
When Nora was threatening, "unprecedented coordination" was required between the NHC and several other agencies. The coordination was "smooth and effective".<ref name="nhcnora1997"/> However, no inland tropical storm warnings were issued for any area in the United States as Nora was approaching from the south.<ref name="nhcnora1997"/>
There are five Pacific Coast breakpoints in the United States. They are, from north to south, [[Point Conception, California|Point Conception]], [[Point Mugu, California|Point Mugu]], the mouth of the [[San Gabriel River]], [[San Mateo Point, California|San Mateo Point]], and the mouth of the [[Tijuana River]], although places outside this area can be selected if conditions warrant.<ref name="nhccaliforniabreakpointslocations">{{cite web|url=http://www.nhc.noaa.gov/breakpoints_list.shtml?|publisher=National Hurricane Center|title=Hurricane and Tropical Storm Watch/Warning Breakpoints|accessdate=2007-12-27|date=2007-06-01}}</ref> Should there be the threat of landfall, [[tropical cyclone warnings and watches|warnings or watches]] would be issued for those sections of coast. It is highly unlikely that any tropical cyclone will threaten the Central Coast or farther north, due to the stronger influence of the [[California Current]].
