Over the last 25 years, the average Nov-Feb rainfall has been

30.33 +/- 5.7 inches

For 95-96, the total is 44.54 inches to Feb 8.

On average 3 inches of rain will fall from Feb 8 to the end of February so the mean to Feb 8 would be around 30.33 - 3= 27.33 inches.

Measure of significance:

44.54 - 27.33 = 17.21

17.21/5.7 = 3.02 dispersion units --> so this is fairly significant but not unprecedented:

in 73/74 the rainfall amounts were:

Nov: 20.48; Dec: 11.82; Jan: 12.80 Feb: 8.42

in 95/96 the rainfall amounts were: Nov: 9.47; Dec: 13.42; Jan: 14.74 Feb (to date) 7.81

There was not significant flooding in 73/74 in the W. Valley because the depth of the snowpack was less.
