Drenching rain will fall on much of California through Tuesday night, bringing some relief to the ongoing drought and raising the risk of flash flooding.
While a series of storms have brought rain to parts of northern and central California over the past few weeks, Tuesday’s storm will bring the first significant rain event for Southern California since the spring.
They’d accept half the state being covered with mud if it meant that the reservoirs were full of rainwater…

The rain may indeed help, but what we need for long term relief is a lot of snow in the Sierras.
I’d note with sufficient cheap electricity, there are straightforward solutions to this problem (and even with CA rates, there’s still a desalination plant opening up in Carlsbad).
