The region known for its gray skies and rainfall is receiving more than its fair share this month.
The Pacific Northwest has received more rain over the past two weeks than it has normally seen for the entire month of November, which is also accumulating to be one of the five wettest months of November. wet never recorded for Seattle.
“Rainfall from November through Sunday was 6.83 inches. Normal for the entire month is 6.31,” said Maddie Kristell, a meteorologist for the National Weather Service (NWS) in Seattle.
“We’re at the tail of a series of two atmospheric rivers that we’ve had in quick succession, almost back to back,” she said.
The current Category 5 atmospheric river targeting the region is on exactly the same track as the last event several days ago.
Extreme precipitation, river flooding, destructive winds, and even landslides are all on the table with this system.
The NWS office in Seattle said, “Record flooding forecast for the Skagit River at Mount Vernon,” north of Seattle.
Cities around the expected high water were ordered to evacuate before the event to help minimize possible dangers.
The rainfall totals with the storm were impressive.
“Some parts of the Olympic Peninsula saw 6 or 7 inches, and even parts of the Cascades saw 4-6 inches as well,” Kristell said.
Melting snow also contributes to flooding.
Areas previously covered in snow now receive rain, causing it to melt quickly and run off into rivers, contributing to their rapid rise.
According to the Seattle NWS, 6.24 inches of rain fell in Sumas, WA and 5.21 inches in Mount Baker in just 24 hours.
With all the extra saturation of the soil, landslides will not only be a danger during the atmospheric river event, but afterwards, as the soil remains wet and unstable.
High winds will also be a major concern. Across the area, winds are expected to gust 30 to 35 mph, but near Skagit County, where significant river flooding is expected to occur, winds could gust to 60 mph or more .
“In terms of wind, this matches our threat of prolonged damage to trees. We could also face power outages in the area,” Kristell said.
She’s hoping her area gets a break from the rain in the next few days, but another system could impact the area by the end of the week.
“It is definitely a unique situation having two atmospheric river events pointing to the same area, ie our coast and Washington in general, ”added Kristell.
A look at the Thanksgiving trip
If you’re leaving town early for Thanksgiving, consider yourself lucky. Things could get pretty risky as we get closer to the holidays.
The weather this weekend promises to be rather calm. There will be a quick show of rain and snow for parts of the Great Lakes.
Rain will develop in the Mississippi Valley for the latter part of the weekend, and more rain is expected for northwest Washington.
However, as we move into the days leading up to Thanksgiving, travel could become a bit of a nightmare if you believe the US weather model for computer prediction this far.
The American model suggests a storm for the Northeast and New England, while the European model does not realize it at all.
The cities we will be watching closely for the Thanksgiving trip next week will be:
- Seattle: for the rain at the beginning of the week
- Washington DC: for the rain a few days before Thanksgiving
- New York City: for rain and even snow several days before Thanksgiving
- Boston: for rain, snow and wind before Thanksgiving
As for temperatures for Thanksgiving week, “Looks like a cold snap mainly for the lower Midwest and the south for Tuesday and Wednesday morning,” CNN meteorologist Monica Garrett said.
“There is a slight rebound, then another more general cold snap for Friday and Saturday, especially for the Northeast.”
