What is depicted in this photo I am quite certain is the base of a towering
cumulous (TCU) formation that is out of the photo to the left. It is quite
common for these structures to develop "rotor" clouds along the forward
leading edge of the storm as they advance. It certainly is not in my
opinion anything associated with hurricane Isabel or any other hurricane
for that matter.
Actually it reminds me very much of a similar formation I encountered in
the central Gulf of Mexico a few years back on a sailing passage from Tampa
to Cancun. A very similar looking formation advanced on us late in the
afternoon and upon sighting it we quickly reefed down and rigged for heavy
weather only to find that it passed over us almost without any real change
in conditions except for a slight elevation in the wind speed. At one
point we found ourselves at the center of what appeared to be a giant smoke
ring about 2 miles in diameter. It was one of the weirdest phenomena I
have ever experienced at sea.
