500 PM AST Tue Jun 23 2020

Dolly's structure has continued to improve somewhat during the day
with convective banding now extending around the eastern and
northern side of the circulation. While water vapor imagery
indicates that an upper-level low is still in the vicinity of
Dolly, that feature is displaced from the cyclone a bit, with some
anticyclonic outflow noted in the cirrus canopy. This
structure further supports the analysis of Dolly's transition to a
tropical storm. For intensity, there is a wide range among
satellite estimates, with TAFB and SAB ranging from 25-35 kt and
UW-CIMSS ADT and SATCON estimates betwe...

A 1348 UTC ASCAT-A scatterometer pass, arriving just after the
previous advisory was issued, indicates that the cyclone is
producing winds of 35-40 kt in its southern semicircle. 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.

Recent satellite-derived wind data indicate that Subtropical
Depression Four has strengthened, and maximum sustained winds are
now 45 mph (75 km/h) with higher gusts. In addition, the wind
field has contracted, and the system has made a transition to a
tropical storm.

A Special Advisory on Tropical Storm Dolly will be issued by 100 PM
AST (1700 UTC) to update the intensity forecast.

Subtropical Depression Four Discussion Number

NWS National Hurricane Center Miami FL

AL042020
1100 AM AST Tue Jun 23 2020

GOES-16 visible satellite imagery shows that the depression's
circulation has become better defined since yesterday, and the
center is exposed just to the north of a band of convection mainly
located within the southern semicircle. This convection is aligned
along the Gulf Stream current, where instability is greatest, and
the system appears a little more tropical than yesterday. However,
the depression is still collocated with an upper-level low, and it
will therefore retain the subtropical designation. The initial
intensity remains 30 kt based on a ST1.5/25-30 kt classification
from TAFB. A...
