I know. I live in Los Angeles. Last winter we had 12 atmospheric rivers over 2 or 3 months, each dumping as much water in a 24h period as Hilary is expected for our area.
Areas like Palm Springs, though, are expecting much more and I’m worried about my friends there.
However, to say a hurricane is hitting California is hyperbole. I’ve been in hurricanes in both Florida and New York.
Unprecedented? How about when the Central Valley fills up with water every 300 years? Is someone actually claiming that this is never happened in the history of California?
