Here is a report from Columbian weather expert and blogger Steve Pierce:
Historic September Rainfall
Portland, Oregon (September 29th 2013) - Heavy September rains are soaking the Pacific Northwest today as the remnants of typhoon Pabuk dumps its moisture on the region. This is a very significant and in some cases historical rainfall event for the month of September. The Portland International Airport has surpassed its wettest September on record with more than 4.38" as of 12 noon PT. The previous September record was 4.30" set back in 1986. The period of record is 1940-Current at the airport. An even more amazing stat is coming out of Astoria, Oregon today. Astoria is closing in on nearly 10" of rainfall for the month, which shatters the old record. Records at Astoria date back to 1890, or more than 123 years! More than 5" of Astoria's total for the entire month of September has fallen since just Friday. Daily rainfall records were also set on Saturday at Vancouver, WA. Hillsboro, McMinnville, Troutdale, Redmond and Salem, Oregon. Winds have gusted to near hurricane force along the Oregon coast this weekend and power has been out at many locations. Storm drains are clogged, causing localized flooding."
What's up next? "A third and very potent September storm will cross the area today and tonight, bringing with it more heavy rain, strong coastal winds and more localized flooding. Trees are susceptible to coming down with the combination of wind, saturated soils and still having their leaves attached which adds more drag to the tree itself. A very special thanks to the Portland office of the National Weather Service for their great stats. Here is the list of the latest Record Event Reports for Oregon as of 12 noon PT" ---
