SEATTLE – Another round of precipitation and windy conditions associated with back-to-back atmospheric river storms in the Northwest will continue to push across portions of Washington State and Oregon on Tuesday.
However, forecasters with the National Weather Service office in Seattle said conditions won’t be as wet as they were with the first atmospheric river storm, which set daily rainfall records in both Seattle and Portland, Oregon on Sunday.
The rain lightened up a bit on Monday. Seattle picked up 0.34 inches of rain, far behind the June 3 record of 1.08 inches back in 1990. Portland reported picking up 0.25 inches on Monday, which was also behind its record of 0.71 inches in 2008.
Flood alerts remain in effect across portions of western Washington through Wednesday morning.
The NWS said the heaviest rainfall will be found in the mountains, where an additional 1-2 inches of rain could fall on Tuesday while totals along the coast should remain between 0.25 and 0.50 inches.
A few hundredths of an inch to a half-inch of rain is also possible across the interior lowlands on Tuesday.
However, the NWS says some thunderstorms are possible on Tuesday which can lead to locally higher rainfall amounts on Tuesday. And while forecasts show rivers will remain below flood stage, tree debris from gusty winds may clog urban drains, and standing water and minor flooding will be possible.
In addition to the rain, which forecasters say should begin to taper off during the afternoon hours, winds will also be high.
The NWS said winds will be between 15 and 25 mph, with gusts as high as 40 mph possible. Those winds were expected to die down late Tuesday morning or in the early afternoon hours.

While the Northwest quickly shifts to a sunny and warm pattern with highs climbing well into the 80s, the first major heat wave of the season is set to sweep across California and the Southwest, and temperatures are expected to climb dangerously high there reaching well beyond 100 degrees starting on Tuesday.
