EPAC: SIXTEEN-E - Remnants

[Yellow Evan]

This storm must not be named if we want that hurricane streak to continue!

It's lasted long enough. I wanna cross another name off the list.

800 PM PDT THU SEP 11 2014

Earlier microwave imagery indicated that the low-level center of
the depression was located near the northern edge of the deep
convection. The convection itself is not all that organized, and
the cloud tops have recently been warming. The system remains a
30-kt depression based on Dvorak estimates from TAFB and SAB. The
vertical shear affecting the cyclone is expected to increase out of
the east during the next 12-24 hours, which should prevent
strengthening during the next couple of days. The depression is
likely to become absorbed by the larger circulation of Tropical
Storm Odile, and the NHC forecast continues to show dissipation by
day 3.

The initial motion is northward, or 360/5 kt. Low clouds to the
east of the depression are already being pulled eastward into
Odile's circulation, and the depression is also likely to be pulled
northeastward and eastward during the next 24 hours. The available
track models are showing a faster eastward motion on this cycle, and
the updated NHC forecast is adjusted eastward near the multi-model
consensus TVCE.

200 AM PDT FRI SEP 12 2014

A 0538 UTC ASCAT-B pass indicates that the center of the depression
is still located on the northeastern edge of the remaining deep
convection, consistent with northeasterly shear of around 10 kt
analyzed over the cyclone by the SHIPS model. The initial intensity
remains 30 kt based on data from the ASCAT pass and the latest
TAFB Dvorak estimate. Easterly vertical shear is expected to
gradually increase today, which should prevent any intensification.
Thee official forecast continues to show the depression weakening to
a remnant low in a couple of days and dissipating as it is absorbed
into the circulation of Tropical Storm Odile by 72 hours. However,
both of these could occur sooner than indicated.

The depression has been drifting northward during the past few
hours. The track guidance shows an eastward to east-southeastward
motion developing during the next day or so as the depression comes
under the influence of Odile's circulation. Given the recent lack of
motion and a trend toward a slower forward speed in much of the
track guidance this cycle, the new NHC track forecast is slower than
the previous one through dissipation. This forecast is close to a
blend of the GFS and the GEFS ensemble mean and is on the fast side
of the guidance envelope.

200 PM PDT FRI SEP 12 2014

The depression is not well organized with limited deep convection
and little, if any, convective banding to be seen. Earlier SSMI,
SSMIS, and a more recent ASCAT overpass showed that the low-level
center was displaced to the east-northeast of a small cluster of
showers. The current intensity is kept at 30 kt based on the
scatterometer data. The ASCAT overpass, however, also showed that
the low-level circulation was becoming elongated from southwest to
northeast. The unfavorable low-level influence of the much larger
circulation of Tropical Storm Odile, located about 800 n mi to the
east, is expected to become increasingly disruptive to the
depression. The system is now forecast to degenerate into a remnant
low sooner than shown in earlier advisories.

Based on the microwave observations and visible satellite imagery,
the cyclone has been moving slowly east-northeastward or 070/3.
The depression or post-tropical cyclone should soon become
entrained into the circulation of Odile and turn eastward to
east-southeastward over the next day or so. The official track
forecast is between the latest ECMWF and GFS solutions.

TROPICAL DEPRESSION SIXTEEN-E DISCUSSION NUMBER 7
NWS NATIONAL HURRICANE CENTER MIAMI FL EP162014
800 PM PDT FRI SEP 12 2014

Tropical Depression Sixteen-E has become poorly organized this
evening. Deep convection is limited to an amorphous blob on the
western side of the increasingly elongated low-level wind center.
The initial intensity for this advisory has been held at 30 kt based
on the Dvorak classification from TAFB. The recent disruption of
the circulation is primarily due to the proximity of the depression
to Tropical Storm Odile, located about 800 n mi to the east. As a
result, the environment around the depression consists of increasing
wind shear in the vertical and horizontal. The environment is
expected to become even more unfavorable while the depression moves
closer to Odile. All of the global and regional dynamical models
forecast that the depression will open up into a trough within 36
hours, and some suggest that this could occur much sooner than that.

The cyclone is beginning to accelerate toward the east and the
initial motion is 110/05. The models remain in good agreement that
the depression, or its remnants, will accelerate toward Odile on a
nearly straight line until dissipation. No substantial changes
were made to the track forecast.

TROPICAL DEPRESSION SIXTEEN-E DISCUSSION NUMBER 9
NWS NATIONAL HURRICANE CENTER MIAMI FL EP162014
800 AM PDT SAT SEP 13 2014

A strong burst of deep convection with cloud tops colder than -80C
have developed during the past few hours near and to the southwest
of the center of TD-16E. In addition, recent passive microwave
satellite images indicate that the low-level circulation remains
well defined despite the moderate northeasterly shear that has been
affecting the small cyclone. The initial intensity of 30 kt is
based on consensus T2.0/30 kt classifications from TAFB and SAB.
UW-CIMSS ADT estimates are T2.5/35 kt, but the intensity is being
held below this value due to the pulsing nature of the deep
convection. The initial position was adjusted slightly southward of
the previous track based on a 1040 UTC SSMI microwave overpass.

The initial motion estimate is toward the east-southeast or 110/06
kt. The depression is forecast to gradually turn more eastward as
it comes under the influence of increasing westerly flow on the
south side of Hurricane Odile, which is located more than 700 nmi to
its east. The only change to the previous forecast track was to add
remnant low positions at 36 and 48 hours given that most of the
global models are now maintaining a discrete circulation a little
bit longer. By 72 hours, however, the small cyclone is expected to
be absorbed into the outer circulation of Odile.

The vertical wind shear is expected to remain moderate from the
northeast and east at 15-20 kt for the next 24 hours or so, followed
by even stronger shear induced by the outflow from Odile as the two
cyclones move closer to each other. As a result, the depression is
forecast to degenerate into a remnant low by 24-36 hours. The
official intensity forecast is similar to the previous advisory, and
closely follows the ICON consensus model.

NWS NATIONAL HURRICANE CENTER MIAMI FL EP162014
800 PM PDT SAT SEP 13 2014

Satellite imagery suggests that the depression is actually somewhat
better organized than it was 24 hours ago. Last-light visible images
showed a well-defined circulation within an elongated broader-scale
cyclonic envelope, obscured by a thick veil of cirrus clouds. A band
consisting of intermittent, cold-topped convection also was noted
on the south side of circulation. Since there have been no
fundamental changes to the cloud pattern since the last advisory,
the initial intensity estimate is held at 30 kt.

Opposing lower- and upper-level flow is creating a hostile
environment of easterly shear over the depression, with global
models showing the shear increasing while the depression nears
Hurricane Odile. The model guidance shows that the shear will
become so extreme that the depression will degenerate into an open
trough in about 24 hours, and the NHC forecast follows suit.

The depression is moving faster toward the east-southeast or
120/08. The small cyclone is expected to accelerate eastward and
east-northeastward during the next 24 hours while it is drawn into
the circulation of Hurricane Odile. The system should turn
northeastward after that time before losing its identity altogether.
