A Puget Sound Convergence Zone (PSCZ) forms when strong westerly winds flow around the Olympic Peninsula and converge over Puget Sound.
It generally forms north of Seattle, and may move southward to as far as Boeing Field or SeaTac Airport.
A PSCZ can cause a narrow band of convective precipitation along it, which can include rain showers, thunderstorms, or snowfall.
Strong south to southwest winds are to the south of the PSCZ and north to northwest winds to the north.
More model information for the winds around SeaTac can be found on the SeaTac Wind Page . |
