I've been noticing on visible imagery today a sort of 'haze' surrounding the Florida Keys.

Thinking perhaps it was just an artifact of the site I was viewing, I quickly checked a half dozen others. And all the sites I viewed showed the same thing:

A sort of "nebulous haze" engulfing the Keys, extending out to perhaps 5 or 10 miles, on both sides of the Keys.

And, on one of the "high zoom factor" satellites I looked at, one could even see a "skinny black line" (as Max Mayfield used to say) *snaking right down the center* of the heretofore unidentified nebulosity, making it appear that some sort of "shaft" had enveloped the notorious Overseas Highway.

Thinking, at first, that it was moisture and evaporation steaming off the Keys (after the drenching it received yesterday), but then wondering WHY it was roughly equidistant on BOTH sides of the road, so to speak, when the stiff southerly wind currently blowing over the Keys should be displacing it towards the northern side of the Islands.

More recently, I'm wondering if it might be *Sand and Sediment* in the water, stirred up by TS Isaac's passage just south of the Keys yesterday, and that it just has not mixed out and fallen back to the bottom quite yet. Your thoughts?
