Rain: Yet More Rain (March 24-25, 2012)

It's been raining off and on since last night--not heavily, but enough that we've already accumulated about half an inch. The forecast is for showers over the next week. This is likely to be our last chance to catch up before the dry season begins in June (although we get sporadic rain in April and May, and a good storm in the coming weeks could be significant, we've typically had most of our rain for the year by the end of March).

Checking the rain gauge on the morning of the 25th, I see that we got 1.25 inches yesterday and overnight. That brings our 2011-2012 rainy season total to 21.30 inches. The historical average for March 25 is 31.68 inches in Santa Rosa. The historical annual average is 31.91 inches--which means that by now we've usually had nearly all the rain we're going to get, so it seems likely that we'll end the rainy season about 10 inches below normal.
