To get a picture of the amount of rain from any storm event we have to use a variety of sources and no one community has just one number. That said, there is certainly plenty of data to look at.

The next two images are 48 hour rainfall totals from the Ventura County Watershed Protection District. These are 2 day rainfall totals from automated equipment captured at 4:31pm. Note there are several locations which are not very accurate, like Paso Robles and Atascadero. Further in this story you’ll get a better picture for both those locations.
To interact with this live data set click HERE. It auto updates and you can also anything from 15 minute rainfall to seasonal rain.
Paso Robles got .52″ in the last 24 hours and now is at 18.23″ for the season. This report is from PR City Water, it does differ from the airport which is considered official by NOAA. However locals think the city report is most representative.
Atascadero got .91″ in the last 24 hours and now more than 22″ for the season.
I will supplement and edit this report as new/additional information becomes available.
