TROPICAL DEPRESSION NINE DISCUSSION NUMBER  13
NWS NATIONAL HURRICANE CENTER MIAMI FL       AL092015
1100 AM AST SAT SEP 19 2015

Visible satellite imagery shows that the center of the depression
is losing definition and becoming elongated. In addition, the
system has been without organized convection since around 0700 UTC.
Given the continued influence of strong shear and dry air, the
system is expected to become a remnant low within 12 hours or could
dissipate as soon as later today if the center continues to lose
definition.

The initial motion has been slower over the past few hours, and the
current estimate is 285/05. The low- to mid-level subtropical ridge
north of the cyclone should steer it or its remnants toward the
west-northwest until the system dissipates completely in the next 24
to 36 hours. The new NHC track is close to the previous one adjusted
for the initial position and motion.
