For folks asking how this compares to our hypothetical "ARkStorm 2.0" scenarios published, a very approximate estimate: we've so far experienced about 1/3 to 1/2 the precipitation we'd expect from such a scenario on a statewide basis. #CAwx #CAwater [1/2]

@weatherwest I assume the 2 to 3x rainfall would need to happen in one event or limited timeframe.

@weatherwest In the purple here. Not in a flood zone, but hardly slept for days while talking to the 60ft trees asking them to hold on.
