Heavy rain from Tropical Storm Moke will begin to impact the Big Island today, risking life-threatening flooding and mudslides in windward and southeast areas. Severe thunderstorms are expected across the northern Rockies/Plains and northern Great Basin. Repeated storms and heavy rainfall may cause flash flooding from the Plains into the Lower MS Valley. Dangerous heat persists across the South. 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 . |
