I think most Californians will welcome rain of an El Nino year a lot. However, the loss of life and homes and property lost is always difficult every time this happens when we have an El Nino year like now. The biggest problem for California is we have elevations from over 14,000 feet in the Sierras and places like Mt. Shasta and then every other elevation all the way to sea level (the entire Pacific Coast (and then below sea level in Death Valley and I believe the Salton Sea area too.) Death Valley I believe goes 100 to 300 feet below sea level which might be part of why it can reach 130 degrees Fahrenheit or more potentially.
I'm wondering when the return of the 1862 type of flooding will occur (unless Global Warming has thrown off this traditional occurrence) which happens like Clock work every 150 to 300 years for thousands of years now. The last big one bankrupted the state and the Capital had to move to San Francisco for 6 months until Sacramento dried out. They had to move the Capital by Boat all the way to San Francisco as no roads were viable between Sacramento and San Francisco then for at least 6 months time.
