Wettest October on Record for Several West Coast Cities
October is typically one of the wettest months of the year for the Pacific Northwest, but this particular October saw rainfall records smashed across a big part of the West.
Spokane, Washington saw its all-time wettest month on record with 6.23″ of rain in October, besting November of 1897, where 5.85″ of precipitation was recorded. Seattle, Washington smashed its previous wettest October with 10.05″ of rain, with its previous high water mark for the month being 8.96″.
Portland, Oregon came within a tenth of an inch of rain of setting their wettest October on record while Redding, California also saw its wettest October on record with 7.78″ of precipitation.
A consistent series of storm systems kept the Northwest active, starting with an early month low pressure center that brought hurricane-force wind gusts and even rare tornadoes to coastal areas, and the rain simply never let up. The jet stream parked over the Northwest for much of the month, depriving coastal Alaska and the Rockies of needed moisture and instead focusing it on Washington, Oregon and northern California.
It’ll stay wet to start November across the Northwest with a series of quick-hitting systems set to keep the Northwest coast grey and damp for the opening week of the year’s penultimate month. That said, no major systems are expected, along the lines of what the Northwest saw in early October.
