A very active weather pattern is setting up for the Pacific Northwest this week. An amplified trough and surface cold front will be sweeping through the Pacific Northwest over the next few days. A surge of Pacific moisture will likely lead to a heavy rain set-up…especially for western Washington. This wet and windy weather pattern will begin Monday night and should last into the weekend. Right now it looks like the snowfall potential will be mostly above 7000 feet so the lower elevations will see all rain.
Street flooding will be possible due to the fall leaves and potential heavy rainfall raters. The threat for street flooding in urban areas will be for Tuesday night into early Thursday. It is recommended to keep storm drains clear of leaves, clutter and debris…by doing this, the flooding threat could be lowered.
Here is a look at the latest rainfall forecast.
In far northwestern Washington there will be the potential of 6 to 12 inches of rainfall through Friday morning. This is the area that will need to be closely monitored for flooding potential over the next few days.
