It’s business as usual this November in Seattle area: More rain is on the way


Seattle Times reporter

The short, non-technical version of the weather forecast for West Washington on Friday and through the weekend is: It will rain more. Lots of it.

It is expected to rain heavily on Friday morning due to an atmospheric river also known as the Pineapple Express, which rises about 30 degrees north over the central Pacific and blows east to northeast towards Washington.

The rain will continue to move inland in the morning hours. The showers will subside in the afternoon and evening, but don’t expect the break to continue. More is on the way from Saturday to Sunday. #wawx

While Saturday is expected to be “more dry than wet” during the day, it will rain heavily on Friday, according to Matthew Cullen of Seattle’s National Weather Service, and it will likely rain again on Saturday night. This rain will be with us until the middle of next week.

In a more detailed statement, the weather service’s Weather Prediction Center said regional Doppler radars show there will be a sizable area of ​​moderate to heavy showers moving over western Washington and northwestern Oregon, particularly the coastal areas, on Friday morning and the western slopes of the Cascade.

“It is in these areas where the current is orthogonal to the terrain and where the greatest amounts of rainfall occur,” said the Weather Prediction Center.

These areas could fall another three inches of rain on Friday, adding to concerns about runoff and flooding.

The Seattle Weather Bureau reported a rumble of thunder Friday at around 12:50 p.m. and said some additional lightning strikes were possible. “When the thunder roars, go inside!” NWS recalled on Twitter.

12:50 am | Did you hear that in Seattle? Yes, you may have just heard a rumble of thunder. Some heavy showers are embedded in the heavier rain, and some additional lightning strikes are possible. Remember: if the thunder is booming, go inside! #wawx
