The 1858 San Diego hurricane was a very rare California hurricane. It is the only known tropical cyclone to impact California as a hurricane, although other systems impacted California as tropical storms.

Meteorological history[edit]

Late in September, a hurricane formed in the East Pacific Ocean, fueled by the abnormally warm 1857-58 El Niño[2] waters. Unlike most east Pacific storms, this one accelerated towards the north-northeast. On October 2, it neared Southern California while weakening due to cool water and strong wind shear. It just missed making landfall, while it turned to the west-northwest. It approached Santa Catalina Island in the Channel Islands and dissipated. There is some uncertainty to this reconstructed path.[1]

Impact[edit]

In San Diego, the rain was very heavy, and the property damage was great; many homes lost at least their roofs, and a few even collapsed. In addition, trees were uprooted, and fences destroyed. A recently constructed windmill was also blown away completely. Three schooners, the Plutus, the Lovely Flora, and the X.L., were blown ashore, although only the X.L. suffered major damage.[1]

Rainfall in San Pedro was also heavy, but high winds were not reported. Parts of the embankment in the city were washed away, causing only around US$100 ($2725.77 today) in damage. The yacht Medora was washed ashore. Many reports claimed that the yacht was irreparable, but it was later claimed that the damage wasn't actually that great and could be repaired.[clarification needed] A barge was destroyed, as was a large portion of the San Pedro wharf.[1]

El Monte was buffeted by high winds, damaging corn crops and trees. Los Angeles and Visalia noted large amounts of rain, as much as 7 inches (180 mm), but low winds.[1]

Two researchers with NOAA Michael Chenoweth and Christopher Landsea reconstructed the path of the hurricane using accounts from newspapers of the strong winds. They estimated that if a similar storm were to have hit in 2004, it would have caused around US$500 million in damage.[3]
