Following an unusually dry and sunny late summer and early autumn, Pacific Northwest weather changed dramatically in early November as a series of strong, wet storms began to affect the region. The most significant was a multi-day rain event caused by copious amounts of subtropical moisture, resulting in one of the wettest periods ever seen in the Northwest. Oregon, Washington and Idaho saw new 24-hour rainfall records set:

WASHINGTON
June Lake (elev. 3,340 ft.): 15.20 inches on November 6-7, 2006
Former Record: 14.26 inches on November 23-24, 1986 (Mt. Mitchell #2, elev. 3,600 ft.)

OREGON
Lee's Camp (elev. 660 ft.): 14.30 inches on November 6-7, 2006
Former Record: 11.65 inches on November 19, 1996 (Port Orford, elev. 150 ft.)

IDAHO
Bear Mountain (elev. 5,400 ft.): 9.40 inches on November 6-7, 2006
Former Record: 7.17 inches on November 23, 1909 (Rattlesnake Creek, elev. 4,000 ft.)

Numerous locations in northwest Oregon and southwest Washington reported more than 7 inches in a single day (most of them on November 6 or 7), as well as other very significant weekly and monthly totals. Table 1 below shows Oregon and Washington one-day totals exceeding 7 inches (not necessarily complete). Nehalem 9 NE, with the second highest one-day total for Oregon (11.77 inches) had a two-day total of 20.69 inches for the 6th-7th.
