Rainfall records shattered this October

KGW Noon Forecast 10-31-16

On this final day of October 2016, much of the Willamette Valley is setting all-time records for total October rainfall and for the number of days with measurable rainfall (meaning .01" or more in a calendar day). 

Portland International Airport will break the record for total rainfall if .12" falls over the course of the day.

Below are new total rainfall records, which will still increase through midnight.

Records for total October rainfall (as of Monday morning):

  • SALEM:  11.19" 
  • MCMINNVILLE:  10.05"
  • VANCOUVER:  8.11"
  • HILLSBORO 8.50"

The October rainfall total as of 8 a.m. Monday at Portland International Airport was 8.30", just .11" shy of the record of 8.41", set back in 1994. 

PDX has seen measurable rainfall 28 of 31 days this month, smashing the old record of 23 days set back in October 1950. 

It is very possible that this October will go into the books as the wettest month of the upcoming rainy season, which typically runs November through March.

Normal rainfall for October in Portland is 3 inches.  The surplus of more than 5" of rain is basically like getting an extra November or December thrown in over the last 30 days.

The outlook for the rest of winter: mostly normal temperatures for the valley with precipitation above normal, and a Mt. Hood snowpack looking healthier than it has in the last couple years.
