'''Hurricane Linda''' was the strongest eastern [[Pacific hurricane]] on record. Forming from a [[tropical wave]] on September 9, 1997, Linda steadily intensified and reached hurricane status within 36 hours of developing. It [[rapid deepening|rapidly intensified]], reaching winds of {{convert|185|mph|km/h}} and an estimated central pressure falling to {{convert|902|mbar|inHg}}. The hurricane was briefly forecast to move toward southern California, but instead, it turned out to sea and dissipated on September 17. It was the fifteenth [[tropical cyclone]], thirteenth named storm, seventh hurricane, and fifth [[tropical cyclone scales|major hurricane]] of the [[1997 Pacific hurricane season]]. |

Samuel: NO IT WAS NOT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! |

While near peak intensity, Hurricane Linda passed near [[Socorro Island]], where it damaged meteorological instruments. The hurricane produced high waves along the southwestern Mexican coastline, forcing the closure of five ports. If Linda had made [[landfall (meteorology)|landfall]] on California as predicted, it would have been the strongest storm to do so since a [[1939 California tropical storm|storm in 1939]]. Though it did not hit the state, the hurricane produced light to moderate rainfall across the region, causing mudslides and flooding in the [[San Gorgonio Wilderness]]; two houses were destroyed and 77 others were damaged, and damage totaled $3.2 million (1997 [[United States Dollar|USD]], $4.3 million 2008 USD). Despite the intensity, the name was not [[list of retired Pacific hurricane names|retired]]. |

== Origins and rapid intensification == |
|||
{{storm path|Linda 1997 track.png}} |
|||
The origins of Hurricane Linda are believed to have been in a [[tropical wave]] that moved off the coast of Africa on August 24. The wave tracked westward across the [[Atlantic Ocean]] and [[Caribbean Sea]] without [[tropical cyclogenesis|development]]. An area of [[convection (meteorology)|convection]] developed to the west of [[Panama]] in the [[Pacific Ocean]] on September 6, which is believed to have been related to the tropical wave. The system continued westward, and within three days of entering the basin, a poorly defined [[Atmospheric circulation|circulation]] formed. [[Tropical cyclone#Physical structure|Banding features]] began to develop, and at around 1200 [[Coordinated Universal Time|UTC]] on September 9, the system organized into Tropical Depression Fourteen-E. At the time, it was approximately {{convert|460|mi|km}} south of the Mexican city of [[Manzanillo, Colima|Manzanillo]].<ref name="tcr">{{cite web|author=Max Mayfield|date=1997-10-25|title=Hurricane Linda Tropical Cyclone Report|publisher=[[National Hurricane Center]]|accessdate=2008-12-25|url=http://www.nhc.noaa.gov/1997linda.html}}</ref> |
|||
Samuel: NO SHUT UP! |

On becoming a tropical cyclone, the depression moved northwestward at {{convert|6|and|12|mph|km/h}}, partially under the influence of a [[Earth's atmosphere#Structure of the atmosphere|mid- to upper-level]] [[low pressure area|low]] near the southern tip of the [[Baja California peninsula]]. Deep convection and banding features increased, and the depression intensified into a tropical storm early on September 10. Upon being designated, the cyclone was [[list of tropical cyclone names|named]] Linda by the [[National Hurricane Center]] (NHC). As upper-level [[outflow (meteorology)|outflow]] became well-established, the storm began to strengthen quickly. By September 11, an intermittent [[eye (cyclone)|eye]] appeared, by which time the NHC estimated that Linda reached hurricane status. The storm began to [[rapid deepening|rapidly intensify]]; its small eye became well-defined and surrounded by very cold convection.<ref name="tcr"/> In a 24 hour period, the minimum [[Atmospheric pressure|pressure]] dropped {{convert|81|mbar|inHg}}, or an average drop of {{convert|3.38|mbar|inHg}} per hour. Such intensification met the criterion for [[rapid deepening|explosive deepening]], an average hourly pressure decrease of at least {{convert|2.5|mbar|inHg}}.<ref>{{cite web|author=National Hurricane Center|date=2007-09-10|title=Glossary of NHC terms|accessdate=2008-12-25|url=http://www.nhc.noaa.gov/aboutgloss.shtml}}</ref> By early September 12, Hurricane Linda reached [[List of Category 5 Pacific hurricanes|Category 5]] status on the [[Saffir-Simpson Hurricane Scale|Saffir-Simpson scale]], and around 0600 UTC, Linda attained estimated peak winds of 185 mph (295 km/h) about 145 mi (235 km) southeast of [[Socorro Island]].<ref name="tcr"/> Its [[maximum sustained wind]]s were estimated from {{convert|180|and|195|mph|km/h}}, based on the [[Dvorak technique]],<ref name="tcr"/> and gusts were estimated to have reached {{convert|218|mph|km/h}}.<ref name="wrh">{{cite web|author=San Diego National Weather Service|date=January 2007|title=A History of Significant Weather Events in Southern California|accessdate=2008-12-26|url=http://www.wrh.noaa.gov/sgx/document/weatherhistory.pdf|format=PDF}}</ref> The hurricane's pressure is estimated at {{convert|902|mbar|inHg}}, making Linda the most intense Pacific hurricane on record.<ref name="tcr"/> When the storm was active, its pressure was estimated to have been slightly lower, at {{convert|900|mbar|inHg}}.<ref name="wm">{{cite web|author=Jesse Ferrell|year=1997|title=Hurricane Linda: History in the Making|publisher=Central Atlantic Storm Investigators|accessdate=2008-12-26|url=http://www.weathermatrix.net/tropical/1997/linda/|archiveurl = http://web.archive.org/web/20070928120154/http://www.weathermatrix.net/tropical/1997/linda/ |archivedate = September 28, 2007|deadurl=yes}}</ref> |

Shortly after reaching peak intensity, Hurricane Linda passed near Socorro Island as a Category 5 hurricane.<ref name="mwr">{{cite journal|author=Miles B.

Forecasters and computer models did not anticipate how quickly Linda would strengthen; in one advisory, the NHC under-forecast how strong the winds would be in 72 hours by {{convert|115|mph|km/h}}.<ref>{{cite journal|author=Kevin R.

Hurricane Linda occurred about a month after the similarly powerful [[Hurricane Guillermo (1997)|Hurricane Guillermo]], which also reached Category 5 status. The passage of Linda cooled the waters in the region, causing [[Hurricane Nora (1997)|Hurricane Nora]] to weaken when it passed through the area on September 21.<ref name="mwr"/> |

Although the eye of Hurricane Linda did not make [[landfall (meteorology)|landfall]], the hurricane passed near [[Socorro Island]] while near peak intensity.<ref name="mwr"/> The hurricane cut power to wind and pressure instruments.<ref name="tcr"/> A station on the island recorded a pressure of {{convert|986|mbar|inHg}} before it stopped producing data.<ref name="wm"/> No [[Tropical cyclone warnings and watches|tropical cyclone warnings or watches]] were issued for the hurricane.<ref name="tcr"/> However, the threat for high tides and strong winds in Mexico prompted officials to issue coastal flood warnings and to close five ports. Waves of up to {{convert|7.8|ft|m}} were reported along the coastline, causing flooding in the [[Political divisions of Mexico|states]] of [[Michoacán]], [[Jalisco]], [[Nayarit]], and [[Sinaloa]].<ref name="r914">{{cite news|author=Staff Writer|publisher=Reuters|date=1997-09-14|title=Hurricane hits Mexican ports, may be headed to California}}</ref> |

[[Image:Linda Calif. forecast.PNG||right|thumb|175px|Forecast track of Linda on September 13 showing a path toward southern California]] |
|||
When Linda was predicted to turn towards the northeast, it was forecast to move ashore in [[Southern California]] as a weak tropical storm, which would have made Linda the first to do so since a [[1939 California tropical storm|tropical storm in 1939]].<ref name="wrh"/> The [[Oxnard, California]] [[National Weather Service]] office issued public information and special weather statements that discussed the possible impact of Linda on southern California. The advisories mentioned forecasting uncertainty, and advised the media not to exaggerate the storm.<ref name="tcr"/> The office noted a threat for significant rainfall—possibly causing [[flash flood]]ing—as well as high surf.<ref name="wm"/> To prepare for possible flooding, workers cleaned storm drains and prepared sandbags for coastal properties.<ref>{{cite news|author=Steve Schmidt|date=1997-09-15|title=Fears ease as Pacific hurricane veers off|publisher=Copley News Service}}</ref> |
|||
Although the storm did not make the turn, {{convert|15|and|18|ft|m}} waves reached southern California.<ref name="wrh"/> In [[Newport Beach, California|Newport Beach]], a wave swept five people off a [[jetty]] and carried them {{convert|900|ft|m}} out to sea, although all were rescued by a passing boat.<ref>{{cite web|author=San Diego National Weather Service|date=2007-11-20|title=Day in Weather History: September 14|accessdate=2008-12-26|url=http://www.wrh.noaa.gov/sgx/document/Dayinhistory/dayhistory0914.pdf|format=PDF}}</ref> Moisture from the hurricane moved across the state, producing heavy rainfall and golfball-sized [[hail]]. A station in Forrest Falls, located within the [[San Gorgonio Wilderness]], recorded rainfall rates of {{convert|2.5|in|mm}} per hour. The rainfall caused severe flooding and mudslides which destroyed two houses, damaged 77 others, and inflicted $3.2 million in damage (1997 [[United States Dollar|USD]], $4.3 million 2008 USD).<ref name="wrh"/> San Diego recorded {{convert|0.05|in|mm}} of rain, the first measurable precipitation in 164 days; this tied the record for the longest duration without rainfall at the station, previously set in 1915 and 1924. Moisture from Linda extended into the [[Upper Midwest]], contributing to a record daily rainfall total of {{convert|1.97|in|mm}} in [[Minneapolis]], [[Minnesota]].<ref>{{cite web|author=National Agricultural Statistics Service|publisher=United States Department of Agriculture|date=1997-09-23|title=Weekly Weather and Crop Bulletin|accessdate=2008-12-27|url=http://usda.mannlib.cornell.edu/usda/waob/weather_weekly//1990s/1997/weather_weekly-09-23-1997.pdf|format=PDF}}</ref> |

With an estimated pressure of {{convert|902|mbar|inHg}}, Hurricane Linda became the most intense Pacific hurricane since reliable records began in [[1966 Pacific hurricane season|the 1966 season]].<ref name="tcr"/> Linda is also believed to have been the strongest since overall records began in the basin in 1949.<ref name="mwr"/> The previous most intense hurricane was [[Hurricane Ava (1973)|Hurricane Ava]] in 1973, which contained a confirmed pressure of {{convert|915|mbar|inHg}}. Since no observations recorded the pressure during Linda's peak, its peak intensity was estimated. As such, Ava remains the strongest measured hurricane in the basin.<ref name="tcr"/>{{EPAC hurricane best track}}<ref>{{cite web|author=Miles B. Lawrence and Michelle M.
