Seattle Local Forecast

October 21st, 2017 morning forecast with KING 5 Meteorologist Ben Dery.


Puget Sound Forecast:  Steady rain, moderate to heavy at times. 1-2" possible. Highs in the mid 50's. South to southwest wind 10 to 15 mph.

Mountain Forecast: Snow turning to rain at pass level. Snow level rising from 3,500 feet this morning to around 6,000 feet this afternoon. A couple slushy inches possible. Pass temps in the lower 40's. Pass wind easterly 10 to 20 mph.

Coast Forecast: Rainy and windy, with gusts up near 45mph. Highs in the low 50's.

Eastern Washington Forecast:  Rain likely, with snow staying up in the mountains. Highs in the mid 40's to low 50's. No snow accumulation is expected.


Today is going to be wet! That's the bottom line as another atmospheric river takes shape over western Washington. Light rain has moved in this morning, and it will likely be with us most of the day turning moderate to heavy at times. Much of the Puget Sound area is looking at 1-3" of rain today, with up to 6" in the mountains! Watch for urban street flooding and rising rivers.

One place in particular to watch is immediately surrounding the Norse Creek burn scar area. 3-6" of rain here may lead to mudslides and flash flooding. Be especially mindful in the valley below Crystal Mountain.

This is a warm front passing today, so expect a rising snow level. It was near 3,500 feet this morning, and is forecast to rise up to 6,000 feet this afternoon. Temps closer to sea-level warm to the mid 50's.

A trough of low pressure keeps the scattered showers in the forecast through Sunday, and it will be breezy as well. The rain should come to a close entirely by Monday morning. We actually dry out for a couple days early next week before another fast moving front gives us some quick-hitting rain Wednesday.

Beyond next Wednesday, some forecast models keep us dry through Halloween! We could use a dry break after three consecutive rain storms!
