POST-TROPICAL CYCLONE RACHEL DISCUSSION NUMBER 26

Rachel artfully draws to a close. Deep convection associated with
Rachel dissipated about 15 hours ago and it is unlikely to redevelop
due to unfavorable thermodynamic factors and strong shear. Based on
these conditions, the cyclone is being declared a post-tropical
remnant low at this time. Dvorak intensity estimates have decreased
further and the initial intensity has been lowered to 25 kt. Global
model guidance shows the remnant low degenerating into an open
trough by Friday. The official intensity forecast is close to the
previous forecast and the GFS model.
During the last couple of hours, the now-shallow vortex associated
with Rachel has taken on a southward drift. A slow southwestward
motion is expected during the next two days as it continues to move
around the eastern periphery of a low-level ridge. The track
forecast is essentially an update of the previous one, nearly

2. between the ECMWF and GFS model solutions.
This is the last advisory on Rachel by the National Hurricane
Center. For additional information on the remnant low please see
