A tropical blast of warm air is starting to be pumped into the Puget Sound region, bringing loads of rain and enough heat to snap records.
Record warm temperatures, flood watches and landslide warnings forecast for Western Washington mean it’s going to be a better holiday for eating than for traveling and skiing.
And frankly, that’s just as it should be, according to National Weather Service of Seattle meteorologist Dustin Guy.
“November is our wettest month of the year, ordinarily, and November as we know it is here,” Guy said.
Tuesday is predicted to warm up as tropical air from the Pacific Ocean, near Hawaii, travels on an atmospheric river, sometimes referred to as the “Pineapple Express,” and works its way up toward Puget Sound.

“It will bring copious rain and warmer temperatures,” Guy said. The high on Wednesday is expected to reach above 60 degrees, topping the record high for the day of 58 degrees.
The milder temperatures will continue through the night, dipping down only to about 55 degrees, and then climbing back up to a predicted high of 58 on Thanksgiving, 9 degrees above the average high of 49, Guy said.
The unseasonable warmth will also raise the snow line up to 8,000 feet Tuesday through Thursday before falling back down to 6,000 on Saturday.
The Weather Service also issued a statement advising that there’s an increased risk of landslides in already water-soaked areas.
The Weather Service is predicting that the Skokomish River will “almost certainly rise above flood stage” on Wednesday night due to 2-5 inches of rain forecast over the south Olympics.
In addition, 2-5 inches of rain over Mount Rainier could produce minor flooding in a number of rivers, including the Cowlitz, Nisqually, Snoqualmie, Stillaguamish, Skagit and Nooksack rivers.
Guy said he doesn’t expect any days he would call dry this week, though Wednesday will be less wet than Tuesday, and Thursday will be pretty wet again.
“It’s going to be a good day for staying indoors and eating all day,” he said.
The rain will lighten slightly on Friday before another system comes in on Saturday, bringing … wait for it … more rain.
“It’s sort of like a broken record: one system every two days and little break in between,” Guy said.
