Seattle Weather: Showers, breezy winds and cooler temperatures Tuesday

Published September 29, 2026 4:00 AM PDT

Our next fall frontal system moves in for Tuesday, bringing widespread showers and breezy winds to western Washington.  Showers will start in the north interior and move southward throughout the day Tuesday. 

The central Puget Sound will see a bit of a rain shadow from the southerly flow, and the heaviest rain is expected in the north interior and coast, the Olympics and along the strait.

Rainfall totals starting Monday evening through late Tuesday show anywhere between 1–3" for the mountains and up to 1.25" for the north interior. 

Winds will pick up Tuesday as the strong frontal system moves inland, bringing the strongest gusts to the north interior and along the Strait of Juan de Fuca. Winds for the Puget Sound will see gusts between 25–35 mph. 

We will need to watch for potential power outages and downed tree limbs as the trees are still heavy with leaves.
