13L Marco

Upgraded to a TS today with 55 kts wind. This storm is very interesting because of the extremely small size. TS wind only extend 30 km from the center(might not be correct but according to this the TS wind field is only 60 km across max). If that is the case, this might be the smallest TC in record, beat out Cyclone Tracy, which has a 96 km wide TS wind field.

EXAMINATION OF THE HIGH-RESOLUTION QUIKSCAT DATA FROM 0100 UTC
SUGGESTS THAT THE RADIAL EXTENT OF TROPICAL STORM FORCE WINDS IS
EXCEEDINGLY SMALL...PERHAPS NO MORE THAN ABOUT 10 NMI.
I think Marco has beaten Tracy.

But one of the problem is the true max intensity of Marco remain unknown. Not saying it was as intense as Tracy, but Marco could have been an hurricane during the peak intensity. There is only one recon plane fly a mission into Marco and at that time it was a 55 kts storm. The true max intensity remain a mystery. Marco got a T-number of 2.0 while the recon plane measure 55kt wind inside Marco so obviously the estimate of the intensity isn't a very good for this particular storm.

But still, Marco should be the new record for the smallest TC.
