In addition, the radius of maximum winds has contracted to about 40 n mi. This, along with the current convective pattern, suggests that the system has made a transition from a subtropical to a tropical cyclone, and it has been designated as Tropical Storm Dolly.

The forecast track and status changes are the same as in the previous advisory.
