A wind gust or just gust is a brief, sudden increase in the wind speed. It usually lasts for less than 20 seconds, briefer than a squall, which lasts minutes. A gust is followed by a lull in the wind speed. From Wikipedia
The storm, following a classic coastal track, is set to deliver 1–3 inches of rain, 50 mph coastal winds, and potential snow in higher elevations before tapering off by Friday.
