Ophelia - A Storm Inside A Storm?

The government's National Hurricane Center issued a very interesting statement this morning:

REPORTS FROM A NOAA RECONNAISSANCE AIRCRAFT INVESTIGATING TROPICAL STORM OPHELIA INDICATED A CENTRAL PRESSURE OF 987 MB...OR 29.15 INCHES...AND A SURFACE WIND OF 55 KT...OR 65 MPH. WHILE THESE DATA APPEAR TO BE GOOD...THEY ARE NOT BELIEVED TO BE REPRESENTATIVE OF THE OVERALL STRUCTURE OF THE OPHELIA. NOAA DOPPLER RADAR DATA FROM MELBOURNE FLORIDA SUGGEST THAT THIS INFORMATION IS ASSOCIATED WITH A SMALLER-SCALE CIRCULATION THAT HAS BEEN ROTATING CYCLONICALLY AROUND THE LARGER CIRCULATION CENTER. THE MOST RECENT DOPPLER RADAR DATA ALSO INDICATE THE SMALL-SCALE CIRCULATION FEATURE HAS WEAKENED CONSIDERABLY

Stuff like this fascinates me.

Afternoon update -- after examining some radar loops (if you have broadband, check out this all-day radar loop) I still don't see what all the fuss is about... looks like just the circulation tightening/loosening or the eyewalls reforming to me.
