That's how much rain is expected to fall in California in the coming week - ten trillion gallons of water.
Yeah, that California, the state that's endured years of severe drought along with brush and forest fires until la nina showed up with atmospheric rivers to essentially drown the place.
Years ago I read of a nomadic pastoralist (herder) in sub Saharan Africa. He lost half his herd one year to flash floods only to lose the remaining half the next year to severe drought. He gathered up his family and their possessions and made off for the nearest city to look for ways to survive.
Now California is the poster child for climate change and global weirding.
It is feared that areas that have been previously hit by forest fires could be more susceptible to mud slides as there is less vegetation to break the flow of running water.
Terry Anzur of KFI News told the BBC the dry, scorched ground that had been "saturated" with the heavy downpour was turning streets in to "rivers of mud".
After five years of drought, a series of storms have filled state reservoirs.
In a season of heavy storms, the latest is expected to be the heaviest by far.
