While not as drenching as the previous event, Sunday's precipitation added almost another half an inch to Washington's soggy December totals. The month-to-date amount of 3.47" is now well above the average for an entire December and over 150% of the month-to-date average. Even an average amount through the rest of the month will be enough for the total to finish over 50% above average. The year-to-date amount of 43.58" is also well above the yearly average of 39.35", although it's almost 3" below last year's near-record total.
