In the past few days, it's rained off and on, and we've had pretty much steady rain since last night (the night of the 20th). So far, we've accumulated another 2.75 inches since last reporting, it continues to rain, and more rain is expected--through Christmas at least. That brings our total to 15.15 inches as of around noon on the 21st, but that will probably rise in the next few days. The historical average for December 20 in Santa Rosa is 9.31 inches, so we remain well ahead of normal rainfall levels.
[Update: On the evening of the 21st, we got another 0.25 inches, bringing the total to 15.4 inches.]
