The ocean waters south of Mexico and Central America are quite warm, but by the time you get up to the Baja peninsula, they are quite cold, comparable to what we see along the New England coast some 15 degrees further from the equator. This is the reason there haven’t been any hurricanes to hit the California coast during my lifetime: storms in the northeast Pacific that make it that far north fall apart in waters that cold. But I recall reading something on Weather Underground to the effect that a hurricane made landfall in what is now San Diego County in 1858, and if the waters off California are warming at a similar rate to other ocean waters, storms like that one would be more likely. Flooding and landslides due to heavy rainfall would probably be the biggest risk (they are used to seeing Santa Ana winds, which can blow with hurricane force, and the topography would limit storm surges to within a few blocks of beaches and harbors).

Not harsh at all. Just pointing out that the pages I looked at for the EP have not received the attention the Atlantic has. The main graphic of the frequency of EP hurricanes by month is years old.
