I saw that swirl too, it might be something becoming cut off from Noel's associated surface trough/developing cold front. The 12Z discussion and surface analysis didn't mention anything here, but the 18Z package should be more interesting..
CARIBBEAN SEA... A TRAILING SFC TROUGH FROM NOEL IS KEEPING ACTIVE WEATHER OVER THE CENTRAL AND PORTIONS OF THE WRN CARIBBEAN. LIGHTNING DATA IS DEPICTING NUMEROUS TSTMS OFFSHORE NICARAGUA FROM 12N-16N BETWEEN 78W-82W. A CLUSTER OF MODERATE CONVECTION IS ALSO NOTED IN THE GULF OF HONDURAS S OF 17N BETWEEN 85W-88W...WITH ONSHORE NLY FLOW. THE TROUGHING IS ALSO GENERATING SCATTERED TSTMS OVER THE COASTAL WATERS OF ERN CUBA...JAMAICA..AND HAITI. SCATTERED SHOWERS ARE ELSEWHERE BETWEEN 71W-83W. SOME OF THE GLOBAL MODELS ARE DEVELOPING A WEAK SFC LOW S OF JAMAICA OVER THE WEEKEND AND DRIFTING IT S/SW...ASSOCIATED WITH THE TROUGHING S OF NOEL. THERE DOES APPEAR TO BE SOME ENHANCED LOW LEVEL VORTICITY IN THIS REGION SO WILL CONTINUE TO WATCH FOR THIS OVER THE NEXT FEW MAPS.

No kidding. You should have seen the clouds from where I was. The outer bands were stunning, then they got lit up by a magnificent sunset. The undersides of the cloud bands went from gold to an incredibly vivid glowing orange-magenta. Their undersides also had the most even wave-like shapes all across the sky. The bands would point sort of this way: | , whereas the waves pointed roughly this way: -- . Wish you could have seen it.
