I like to search/zoom in round the world using Ecowitt's weather map.  Looks like some big rainfall totals (70mm/2 3/4") North of Santa Clara (unless he is cleaning his rain sensor )  Most other data on his station looks pretty stormy.  https://www.ecowitt.net/home/index?id=83194

That station eventually recorded 164.1mm (6.4").

In Ventura (CA), we only measured 1.35" total as of 8:30am on Monday. We are on the western edge of the storm path, so did not quite get the same amount of rain and wind.

I wonder if all that shaking from the earthquake added to my rain total?

Just 15 miles to the southeast in Camarillo, I recorded 3.76" of rainfall from Hilary (from both an automated Davis rain gauge and a manual Stratus rain gauge).  Amazing how quickly the impacts of a storm like this can change over the course of just a few miles.

What's weird is that only a few inches of rain can create massive flooding in some areas.  Death Valley roads were closed due to flooding at least twice this year.  Is it terrain, or is the ground so dry and hard it doesn't absorb water very well?

It's both terrain (mountains) and hard, impermeable soil .. the water can't 'soak in' so pools and runs off downhill.
