Viticulture and Oenology
This harvest report for the Oregon wine industry from 2013 describes the season as "a play in two acts, with a wet intermission." Vintners were surprised by record rainfall one weekend in late September after a warm and dry summer. The rains, remnants from a typhoon in Japan, mostly affected the Willamette Valley, but effects were variable even within that region; southern and eastern Oregon were less affected by the storm.
