No hurricane has made it to Los Angeles in my lifetime, my parents' lifetime, my grandparents' lifetime, or my great grandparents' lifetime.
You have to go back to October 1858, where "the San Diego hurricane" made landfall to both San Diego and Los Angeles. In the 164 years since, there have been no hurricanes in California.
In September 1997, Hurricane Linda was forecasted to finally break that streak, and hit Los Angeles. I didn't believe it. I said that it would either change course or die in the cold Pacific Ocean -- which is basically a hurricane killer in California.
This was a picture of Hurricane Linda, on September 12, 1997:
Indeed, it ended up shifting course, went out to sea, and died. It ended up being no big deal.
Now Hurricane Kay, located in a similar spot to 1997's Linda, is considered having the best chance to hit LA as a hurricane since Linda. However, unlike Linda, this one is not expected to actually do it, but instead is expected simply to come close to LA before degrading into a tropical storm or depression before hitting land.
The storm is expected on Friday night, and will stay through Saturday.
