  NHC:40%  
1. Showers and thunderstorms have increased tonight in association with
an area of low pressure centered several hundred miles
south-southwest of Manzanillo, Mexico.  Conditions are conducive for
additional development, and a tropical depression could form within
the next two to three days.  After mid week, this system is likely
to interact or merge with the disturbance to its east, and further
development after that time is not anticipated.
* Formation chance through 48 hours...medium...40 percent.
* Formation chance through 5 days...medium...50 percent.

NHC展望提升至High,80%/80%
1. A small area of low pressure centered several hundred miles
south-southwest of Manzanillo, Mexico, continues to become better
organized.  Any significant increase in organized thunderstorm
activity will likely result in the formation of a tropical
depression tonight or tomorrow.  Beyond mid week, strong upper-level
winds from the system to the east could inhibit further development
while the low moves slowly west-northwestward or northwestward.
* Formation chance through 48 hours...high...80 percent.
* Formation chance through 5 days...high...80 percent.

Tropical Depression Fourteen-E Discussion Number   1
NWS National Hurricane Center Miami FL       EP142019
900 AM MDT Tue Sep 17 2019

Deep convection has intensified over the small area of low pressure
that NHC has been monitoring for several days.  Both SAB and TAFB
estimates indicate that there is now enough organized thunderstorm
activity to initiate advisories on a tropical depression, and the
initial wind speed of 30 kt matches the overnight scatterometer
data and the subjective Dvorak estimates.

The initial motion is an uncertain 335/8 kt, with steering provided
by a distant low-level ridge to the east.  The cyclone is forecast
to gradually turn toward the northwest and west-northwest during the
next several days as it runs into the southwestern side of a mid-
latitude ridge centered over northwestern Mexico. The biggest
complication is Tropical Storm Lorena to the northeast, which some
of the model guidance, such as the 6Z GFS, shows a binary
interaction with at longer term, which could induce a more northward
motion. While I can't rule that out, the forecast will stay closer
to the models that show less interaction, such as the more westward
HWRF and ECMWF solutions, and the NHC forecast is close to a blend
of those models.

While almost all of the guidance indicates strengthening of this
depression into a hurricane in a few days, this forecast is
problematic because of the proximity to Lorena.  Convective outflow
from Lorena could induce more easterly shear than is currently
forecast if the tracks get closer together.  For now, since the
cyclones are forecast to remain a fair distance from one another,
this wind speed prediction assumes that the low-shear environment in
most of the models materializes, and the forecast follows the
corrected-consensus intensity guidance HCCA.

Tropical Storm Mario Discussion Number   2
NWS National Hurricane Center Miami FL       EP142019
300 PM MDT Tue Sep 17 2019

Thunderstorm activity continues to grow over the center of the
cyclone, with a banding feature trying to form in the western
semicircle.  While the subjective estimates are unchanged from
earlier, the objective estimates are rising, which matches the
increased convective organization trend on satellites.  Thus the
initial wind speed is bumped up to 35 kt on this advisory.

Mario is moving northwestward, with that general motion anticipated
for the next two days due primarily to a mid-latitude ridge centered
over northwestern Mexico.  A slow west-northwest track is forecast
at long-range due to the orientation of the weakening ridge. Global
models have come into much better agreement overall, and the new NHC
track forecast is shifted to the west during the next few days since
the models suggest little-to-no interaction with Tropical Storm
Lorena.

With the guidance showing less interaction with Lorena, it seems
probable that further strengthening will occur in a low-shear,
warm-water environment.  Interestingly, the guidance is actually
lower than this morning, although it is difficult to pinpoint any
reasons for the change. I've elected to let the morning forecast
ride for one more advisory to see if the guidance comes back
upward, and the latest wind speed prediction is at the upper end of
the guidance envelope.
