A Nor'easter will create hazardous marine and coastal conditions along the Mid-Atlantic coast through mid-week, with significant coastal flooding and beach erosion possible. Meanwhile, another strong storm system is forecast to bring high winds and heavy precipitation to portions of southern Alaska. Elsewhere, relatively benign weather is expected through the first half of the work week. Read More >

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 . |
