You’ve had dry. Now get ready for wet.
A drenching Pacific storm headed toward Washington state could bring 1 to 2 inches of rain in the Western Washington lowlands and 4 inches of rain in the mountains, according to the National Weather Service.
Heaviest precipitation is expected between midday Thursday and midday Friday.
The forecast for tonight and tomorrow is a 50 percent chance of showers and thunderstorms, some producing heavy rain, according to the weather service.
Thursday night will be wet as well, with almost certain rain and possibly a thunderstorm, and a low around 60, the service reports.
Friday? More rain. The weather service predicts a high of 69, with a 90 percent chance of showers. Friday night the rain could let up a bit, though, with a 30 percent chance of rain. It is supposed to be mostly cloudy, with a low around 58, the weather service says.
The predicted downpour could create some urban flooding, as well as floods in small streams, according to a “Special Weather Statement” from the Weather Service.
The predicted rain would be a sharp contrast to the sunny, dry summer Seattle has had. Seattle-Tacoma International Airport, where the area’s official readings are taken, had just 2.65 inches of rain in the entire June-July-August period.
The approaching storm prompted Seattle city officials to warn construction crews to inspect and maintain storm drain “socks,” temporary inserts often used to capture sediment from construction projects.
“The predicted weather system will not be huge by winter storm season standards, but for a time of the year that is normally dry it will be powerful,” said Seattle Public Utilities meteorologist James Rufo-Hill.
The good news: The forecast still calls for a mostly sunny weekend in the Puget Sound area, with highs Saturday and Sunday in the mid to upper 70s.
