Tropical Storm Gert Special Discussion Number   7
NWS National Hurricane Center Miami FL       AL062023
1200 AM AST Mon Aug 21 2023

Recent satellite wind-derived data indicated that winds in the
northeast quadrant were a little over 35 kt.  Conventional enhanced
infrared imagery showed cooling cloud tops of -85 Celsius in the
same region of the cyclone.  Accordingly, the depression is
upgraded to a tropical storm on this Special Advisory.

No changes to the forecast track and intensity philosophy are
required.  Since the environment is still expected to be
hostile with very strong westerly shear during the next day or so, 
Gert should degenerate into a remnant low later today, and 
dissipate by Tuesday.
