2013 certainly won’t go down as one of the wettest in Portland.
“We’re at 26. 72 inches for the year. That’s more than nine inches below where we should be (by now)” says KGW Meteorologist Rod Hill. “That’s good enough for the fifth driest year on record, and those records (at PDX) go back to 1941.”
The likely reason for the below normal rainfall is the weather pattern known as El Nino, which often means a milder and drier winter for the Pacific Northwest.
“It now appears likely that neither El Nino or La Nina will be present this winter,” Steve Pierce with the Oregon chapter of the American Meteorological Society told OregonLive last fall. “We are likely to see a little bit of everything this winter as evidenced already by the record-setting wet September followed immediately by a long spell of dry weather in October. Large variability in month-to-month weather is common in years where there is no clear signal in the tropical Pacific. All of Mother Nature’s cards are on the table this winter.”
September was the wettest month of the year in Portland according to Hill. We received over five and a half inches of rain.
