WASHINGTON — Western Washington will once again see very wet and breezy conditions tonight through Thursday morning.

While overall rainfall might not be as heavy in spots as in Round 1 on Monday, this will last a bit longer, soils are completely saturated, and river systems cannot hold more water without flooding.

Forecast for Tuesday Night Dec 9 Forecast for Tuesday Night Dec 9

As rain moves back into the area tonight, another Wind Advisory will go into effect, with gusts in the 40-45 mph range from tonight through the day on Wednesday.

These winds will cause more issues with fallen trees, as soils are now saturated in many areas from 1-4 inches of lowland rain on Monday and Monday night. Power outages are likely to increase.

Then there is the rainfall and flooding threat. Some forecast models have this next round of rainfall topping out in the 2-4″ range in the lowlands from Tuesday night through Thursday morning with 5-10” in the mountains.

This is what we saw as an average through Sunday night and Monday, though drawn out over a longer period.

Still, there will be issues with urban flooding when the heaviest downpours hit, as storm drains are not equipped to handle the rainfall rates we’re likely to occasionally see.

Rivers will spike higher once again. Major flooding is expected on many of our river systems with crests higher than what we observed on Monday and into Tuesday.

Major flooding is expected on the following rivers with the following times of peak river levels (subject to change with new forecasts):

Puyallup River –

Near Orting:

Will reach an even higher crest Wednesday morning at 10 a.m. in major flood stage.

At Puyallup:

Will crest again higher, but still in minor flood stage around 10 a.m. Wednesday

Snoqualmie River –

At the Falls:

Next crest even higher in major flood stage at 58,000 cfs at 10 p.m. Wednesday, then quickly falling.

At Carnation:

Falling overnight and then an even higher crest near 60 feet Thursday morning at 10 a.m. (about 2.2 feet below record.)

Tolt River –

Near Carnation:

Cedar River –

Reaches minor flood stage Wednesday afternoon reaching a crest of 17 feet Thursday morning, just shy of record level.

Other Rivers –

Tolt River at Carnation: Wednesday afternoonCarbon River near Fairfax: Wednesday afternoonNisqually River near National: Wednesday nightCowlitz River at Randle: in major flood stage now through Friday morningCowlitz River at Packwood: Wednesday morning

Some minor coastal flooding is also possible, especially near the time of high tide and near where rivers empty into the Salish Sea.

Drier weather will be in the forecast from Thursday afternoon through Friday and the weekend with most rivers dropping quickly into the weekend though hazards will still remain, with debris and dangerous river currents.

While the weekend’s weather looks calmer, there are prospects for more warm, wet, windy weather systems next week – possibly with some atmospheric river components.

It appears that we won’t have an end to the flooding threat in Western Washington through next week.

KIRO 7 will have live team coverage of this ongoing flooding threat through the event. Stay with us on-air and online.
