Scattered severe thunderstorms are possible across parts of the Ohio Valley and Mid-Atlantic this afternoon and evening. Strong to severe wind gusts capable of producing wind damage should be the primary hazard, but isolated hail may also occur. Thunderstorms may bring heavy to excessive rainfall and possible flooding today over the northern Gulf Coast and upper Ohio Valley. 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 . |
