Tropical Storm Cindy Discussion Number  15
NWS National Hurricane Center Miami FL       AL042023
500 PM AST Sun Jun 25 2023

This afternoon, we have had a wealth of in-situ observations, both 
from an Air Force Reserve reconnaissance aircraft sampling Cindy, in 
addition to a NOAA buoy that very recently was in the center of the 
tropical storm. The aircraft observations indicate that Cindy still 
has strong winds in its northeastern quadrant, but well removed from 
the center and more related to transient convection. Both the plane 
and the surface buoy indicate that the minimum pressure with Cindy 
continues to increase, now near 1010 mb. The wind field on the 
western side of the storm is also quite diffuse and is barely closed 
given the light west winds observed on the south side by the 
aircraft. Satellite intensity estimates continue to drop from both 
TAFB and SAB, but the initial intensity will remain 40 kt for this 
advisory, out of respect for the higher flight-level winds.    

Cindy has continued to move northwestward this afternoon, with the 
latest estimated motion at 315/14 kt. The track forecast is 
essentially unchanged from earlier today, as Cindy should continue 
this northwestward track until it opens up into a trough in 24 to 36 
hours. The NHC track lies very close to the various consensus aids. 
This track forecast does not preclude the possibility of some 
possible center nudges poleward due to the enhanced convection 
ongoing in the northeast quadrant of the storm. 

Cindy might be having one last convective gasp this afternoon, as 
continued strong southwesterly vertical wind shear and dry mid-level 
air are likely to lead to its demise. The vast majority of the 
guidance now suggests the storm will soon open up into a trough 
axis. The latest NHC intensity forecast continues to indicate 
dissipation after 24 hours, though this could occur sooner than 
indicated here. There remains a possibility of regeneration later 
this week near or to the north of Bermuda, but enough uncertainty 
exists to not show this scenario in the current official forecast.
