We've had rain on and off in the past week, including a heavy downpour early on the morning of December 4 (this morning). This morning there was 1.9 inches in the rain gauge. That's in addition to a little over two inches earlier in the current rain year, which brings our total to just about four inches.
[More rain overnight and into the morning of December 5 added another 0.65 inches, bringing the total to 4.65 inches.]
[Rain again into the morning of December 6 has added another 0.80 inches, bringing the total at my location now to 5.45 inches.]
[By the morning of 12 December, another 2.90 inches had accumulated. That brings the total to 8.35 inches as of 12 December at my location, but I'm using the newer rain year definition that counts rain from October 1 through the following September 30, My understanding was that there was an older definition of the rain year going from July 1 forward.
Having said that, once source I found says "A water year is defined by hydrologists as the 12-month period that starts Oct. 1 and continues through Sept. 30 the following year. A rainfall year season is defined as the 12-month period beginning July 1 that continues through June 30 of the subsequent year." So, apparently there is a water year and a rainfall year season. Maybe I'm wrong about the definition having been changed. The same source* says 7.46 inches is the historical average for Santa Rosa by this date. So, in any case, it looks like we're a little ahead of usual--which is good.
