The average annual precipitation recorded by the
Alaska Meteorological Team at Fort Greely, just south of Delta Junction,
is 11.12 inches, in over 30 years of record-keeping. This varies around
the general area - some places get a little more, some a little less. Average annual snowfall is 40.5 inches and the water content of that snow is included in the total precipitation figure given above.

In the photo below by Donna Gardino a summer flash flood took out a
bridge on the Richardson Highway for several days -- an uncommon occurrence
around the Delta area.
The snow that falls in Interior Alaska is quite
'dry' - an inch of snow melts down to less than one-tenth of an inch of
water. (It isn't much good for building snowmen or for making
snowballs.) Early fall and late spring snows, when the air is warmer,
usually contain more water.
