Fog

It's 2pm (1400) and I look out the window and see fog so dense it looks like smoke. It's just billowing past us in great drifts and making everything hazy. Except I look out at our view of the ocean and 200 feet away is completely obscured by fog. In a matter of just 10-20 mins a dense, pea soup fog has taken over my clear radiant skies and still appears to be billowing like a large fire. I have never seen fog so swirled and pushed around by wind so quickly, especially at 2 in the afternoon. My camera isn't good enough to pick this up very clearly even though I took a few videos of it.
