Summer Review: Rain

The climatological highlight for Summer 2010 in Interior Alaska must be the extreme rainfall over the upper Tanana Valley and Fortymile country in late June and July and the attendant flooding.

Northway measured 13.85" of rain June through August. This is almost 2 and half times normal, and is 4" more than the annual normal! This by far the wettest summer of record in Northway. Eagle, with 10.09" of rain also recorded the wettest summer of record. The flooding on the Fortymile River in July was the greatest of record, and the Taylor Highway beyond the Top of the World Cutoff was closed more often than open due to mudslides and the roadbed simply sloughing away.
