Remnants Of Wilfred Discussion Number 11
NWS National Hurricane Center Miami FL AL232020
1100 PM AST Sun Sep 20 2020

Northwesterly vertical wind shear has continued to take a toll on
Wilfred. Recent infrared satellite imagery along with scatterometer
data indicate that Wilfred's low-level circulation has become an
open trough of low pressure. Therefore, Wilfred is no longer a
tropical cyclone and this will be the last NHC advisory on this
system. The remaining deep convection has a linear shape and
appears to be the result of the system interacting with an
upper-level trough to its northwest. The scatterometer data
revealed peak winds of close to 30 kt to the north of the trough
axis, and that is the basis for the initial intensity.

The system is moving generally westward at about 15 kt. The trough
should continue to move westward at a slightly slower forward
speed until it weakens and dissipates within a few days.

This is the last NHC advisory on Wilfred. Additional information
on the remnants of this system can be found in High Seas Forecasts
issued by the National Weather Service, under AWIPS header
NFDHSFAT1, WMO header FZNT01 KWBC, and online at

Tropical Depression Wilfred Discussion Number 10
NWS National Hurricane Center Miami FL AL232020
500 PM AST Sun Sep 20 2020

Wilfred is not a healthy tropical cyclone as strong vertical shear
from the combination of outflow from Hurricane Teddy as well as
winds on the southern side of a nearby upper-level trough are
impinging upon the system. While there is substantial deep
convection, it is more linear rather than curved in appearance and
it may be more a product of forcing from the upper-level trough
rather than the tropical cyclone itself. Dvorak classifications
from SAB and TAFB have reduced some at 18Z, though the intensity
remains a perhaps generous 30 kt.

The tropical cyclone continues to move west-northwest at a fast 17
kt clip. As the system slowly winds down, it will be increasingly
steered by the low-level flow indicating a slower movement toward
the west or west-northwest until dissipation. The new track
forecast is similar to that from the previous advisory, except for
the final 60 hr point that does show a turn toward the northwest
based upon the TVCN and HCCA track consensus techniques.

Strong shear and dry mid-level humidities should continue to cause
a reduction in the deep convection and lead to the system becoming
a remnant low in a day or two followed shortly thereafter by
dissipation. Most statistical and dynamical intensity guidance is
in agreement. A plausible alternate scenario is that the small
circulation opens up into a trough and dissipation occurs sooner
than indicated below. It is worth noting that the ECMWF model does
suggest the possibility of reformation of the system farther north
by day three. However, this scenario is discounted at this time.

Tropical Depression Wilfred Discussion Number 9
NWS National Hurricane Center Miami FL AL232020
1100 AM AST Sun Sep 20 2020

First-light visible imagery of Wilfred shows a well-defined center
south of widespread - but not very well banded - deep convection.
The improved positioning this morning allows for a more confident
assessment of its movement toward the west-northwest at 17 kt. As
the system slowly winds down, it will be increasingly steered by
the low-level flow indicating a slower movement toward the west or
west-northwest until dissipation. The new track forecast is
slightly farther west due to the faster initial motion within 36
hours, then slightly farther east afterward based upon the TVCN
track consensus approach.

While the ASCAT scatterometer passes this morning missed Wilfred's
center, ASCAT-B observed 30 kt peak winds in its northeastern
quadrant. This value is used as the initial intensity, consistent
with both SAB and TAFB's Dvorak classifications.

The combination of outflow from Hurricane Teddy as well as winds on
the southern side of an impinging upper-level trough are causing
about 20 kt vertical shear from the west-northwest. This shear
should increase over the next couple of days as Wilfred gets into
closer proximity with the trough. The strong shear and dry
mid-level humidities should continue to cause a reduction of the
deep convection and lead to the system becoming a remnant low in a
couple of days followed within another day or so by dissipation.
All statistical and dynamical intensity guidance is in agreement
with this scenario. Alternatively, Wilfred could become a remnant
low sooner, if the convection ceases later today or Monday.

Tropical Storm Wilfred Discussion Number 8
NWS National Hurricane Center Miami FL AL232020
500 AM AST Sun Sep 20 2020

It is unclear if Wilfred still exists, and if so, exactly where it
is located. Although there is clear evidence of a broad elongated
circulation, the formerly small center of Wilfred is either
obscured by higher clouds or has dissipated. AMSR-2 microwave
imagery at 0431 UTC showed only evidence of a northwest-southeast
oriented trough with one or more embedded mesoscale lows. Visible
imagery and the next round of ASCAT passes will hopefully provide
more information about Wilfred's status later this morning. The
intensity remains 35 kt based on ASCAT data from last night, but
more recent Dvorak estimates are lower.

Due to the uncertainty associated with Wilfred's status and
location, the motion estimate is a very uncertain 295/15 kt. In
general, Wilfred or its eventual remnants should continue on a
west-northwestward heading today, and then could turn westward by
early Monday. The NHC forecast is very similar to the previous one
and lies near the middle of the guidance suite.

Virtually no change has been made to the official intensity
forecast. Wilfred will likely gradually weaken until it dissipates
due to a combination of increasing wind shear and a dry
environment. The exact point at which Wilfred will become a trough
varies from model to model, but confidence is fairly high that
Wilfred won't last much longer than another day or two. The NHC
forecast carries Wilfred for 48 h based on persistence from the
previous advisory, but if recent trends hold, it could dissipate as
soon as later today.

Tropical Storm Wilfred Discussion Number 7
NWS National Hurricane Center Miami FL AL232020
1100 PM AST Sat Sep 19 2020

Microwave data since the previous advisory indicates that the
center of Wilfred is located near the southwestern edge of the deep
convection. The displacement of the center from the convection
is the result of moderate westerly vertical wind shear. The
initial intensity remains 35 kt, and is based on an ASCAT-B
overpass from around 0000 UTC that revealed peak winds of 30-35 kt.

Wilfred is headed toward an area of increasing westerly wind shear,
and a drier mid-level environment. These negative factors should
lead to weakening in 24 to 48 h, and the global models dissipate
the cyclone within the next few days. The official forecast
follows suit, but given the small size of the cyclone it could
weaken and dissipate sooner than indicated below.

The initial motion estimate is 295/14, a little faster than before.
Wilfred is forecast to remain on a west-northwestward heading
through Sunday, but should turn westward within the low-level flow
by Sunday night or Monday. The latest NHC track forecast is once
again similar to the previous advisory and near the middle of the
guidance envelope.

Tropical Storm Wilfred Discussion Number 6
NWS National Hurricane Center Miami FL AL232020
500 PM AST Sat Sep 19 2020

A small low-level swirl that is apparently Wilfred's circulation
center was noted in late afternoon visible imagery. The coldest
cloud tops are in a small area of bursting convection to the
northeast of the center with a ragged convective band noted to
the south and southwest. The latest objective and subjective
satellite intensity estimates remain 35 kt, and that will be the
intensity for this advisory, but could be a bit generous.

Increasing westerly shear and a drying airmass along the forecast
track should result in weakening within 36 to 48 hours, and global
models show the cyclone dissipating by 60 h. However, given the
small size of the system, it wouldn't be surprising if the cyclone
weakened or dissipated sooner than shown here.

The initial motion estimate is 290/12. Wilfred should continue
west-northwestward for the next 24 to 36 hours before turning
westward in the low-level flow prior to dissipation. The new NHC
track forecast is close to the previous one and lies near the
consensus aids and the middle of the guidance envelope.

Tropical Storm Wilfred Discussion Number 5
NWS National Hurricane Center Miami FL AL232020
1100 AM AST Sat Sep 19 2020

Wilfred still consists of a very small low-level circulation
embedded within an elongated area of low pressure. There has been a
bit of an increase in deep convection near/over the estimated center
during the past few hours, and the intensity remains 35 kt based on
the latest Dvorak classifications from TAFB and SAB and UW-CIMSS
SATCON.

Wilfred will be moving over SSTs of around 28C but will experience a
gradual increase in westerly shear during the next 24 to 36 hours as
an upper-level trough amplifies to the northwest, and this should
result in little change in strength during that time. Beyond that
time, the cyclone moves into a drier and more stable airmass, which
should result in the system becoming a remnant low and dissipating
in 60 to 72 hours. The new NHC intensity forecast is close to the
latest IVCN consensus.

The initial motion estimate based on the latest satellite fixes
is 285/12. Wilfred should continue moving generally west-
northwestward for the next 24 to 36 hours and then turn more
westward by 48 h as it becomes a shallower system. The new NHC
track forecast is a bit faster than the previous one and has
been adjusted farther south at 36 h and beyond, trending toward
the latest consensus aids.

Tropical Storm Wilfred Discussion Number 4
NWS National Hurricane Center Miami FL AL232020
500 AM AST Sat Sep 19 2020

Helpful AMSR microwave imagery from near 4Z revealed that Wilfred
consists of a small low embedded within a broader elongated
area of low pressure. A skinny, ragged band of convection wraps
around the western and southern portions of the tropical storm, but
Wilfred is only producing a small amount of convection near its
center. Objective and subjective satellite intensity estimates are
generally near 35 kt, and the intensity is held at that value.

No noteworthy changes were made to the NHC track or intensity
forecasts. Wilfred should continue to move generally
west-northwestward for the next few days, steered by a
subtropical ridge to the north. Small fluctuations in intensity are
possible for the next day or two, but Wilfred should be on the
overall decline by the end of the weekend due to increasing wind
shear and an expected influx of dry, stable air. The dynamical
guidance consensus is that Wilfred will open into a trough and
dissipate in about 72 h, and this is reflected in the NHC forecast.
Both the NHC track and intensity forecasts are based on the
multi-model consensus throughout the forecast period.

Tropical Storm Wilfred Discussion Number 3
NWS National Hurricane Center Miami FL AL232020
1100 PM AST Fri Sep 18 2020

Conventional satellite imagery shows that Wilfred's surface
circulation has lost quite a bit of definition during the last
several hours, and it has been difficult to pinpoint the center.
Additionally, deep convection has become less organized and the
cloud tops just to the east of the estimated center position have
warmed considerably. The initial intensity is generously held at
35 kt for this advisory and is in best agreement with blend of the
subjective and objective satellite intensity estimates.

The GFS and ECMWF global model soundings indicate 30-35 kt of
northeasterly shear at about 300 mb, and it's apparently
undercutting the much lighter, diffluent southeasterly flow above.
Statistical-dynamical guidance, however, still show an outside
chance of some strengthening Saturday, and the NHC forecast follows
suit. Afterward, a combination of Teddy's massive outflow and
increasing northwesterly shear produced by an mid- to upper-level
trough to the north of the cyclone, should induce slow weakening on
Sunday and this trend should continue through the forecast period.

The initial motion is estimated to be west-northwestward, or
285/16 kt, and the cyclone is being steered by a low to
mid-tropospheric subtropical ridge to the north. A few of the
global models are hinting at a slow turn toward the north-northwest
prior to dissipation as the steering pattern becomes very meridional
with developing high amplitude high pressure over the eastern
Atlantic, and Hurricane Teddy well to the northwest creating a large
weakness over the western Atlantic. For now, the NHC forecast shows
some reduction in forward speed at day 3, before dissipation, and
lies close to the consensus aids, HCCA and TVCA.

Tropical Storm Wilfred Discussion Number 2
NWS National Hurricane Center Miami FL AL232020
500 PM AST Fri Sep 18 2020

There haven't been a lot of changes with Wilfred today, with the
northern side of the circulation looking rather dry while the
center remains close to a burst of convection. The initial wind
speed is kept 35 kt, closest to the TAFB classification. Wilfred
could strengthen some during the next day or so before increasing
upper-level westerlies winds likely begin by Sunday. A gradual
weakening is expected into early next week, though the model
guidance is in worse agreement than the last advisory due to the
positioning of an upper-level low. The forecast continues to
show the storm ending up on the convergent side of the low and
dissipating, close to the previous one.

Wilfred is moving west-northwestward at about 16 kt, after
accounting for a re-positioning westward. Most of the guidance
agrees on a scenario that maintains this track for the next few
days, with a turn toward the west as the cyclones dissipates. The
new forecast is closest to the GFS-based guidance. Similar to the
intensity forecast, however, there are some models that suggest
Wilfred could slow down and turn to the right in a couple of days if
it is stronger than anticipated.

Tropical Storm Wilfred Discussion Number 1
NWS National Hurricane Center Miami FL AL232020
1100 AM AST Fri Sep 18 2020

Satellite images indicate that the broad area of low pressure over
the eastern Atlantic has become better-defined this morning. In
addition, scatterometer data also show a closed circulation, albeit
with some rain contamination causing some noise near the center.
The initial wind speed is set to 35 kt, in accordance with
scatterometer data from last night (this morning's data missed the
eastern side of the storm). Thus Wilfred has formed, continuing
the record-setting pace of the 2020 hurricane season since it is
the earliest 21st named storm on record, about 3 weeks earlier
than Vince of 2005.

Further intensification is possible during the next day or two
before a large upper-level trough is forecast to drop into the
path of the storm and stay there for at least a few days. That
should promote weakening due to a substantial increase in shear, and
most of the global models show this tropical cyclone opening up
into a trough by day 5. The official forecast follows this
scenario, and the NHC intensity forecast is a blend of the
consensus and corrected-consensus aids.

Wilfred is moving west-northwestward at about 15 kt. The storm
is forecast to continue this motion for the next several days,
owing to steering from the low- to middle-level subtropical ridge.
The guidance is in fair agreement, and the official forecast is
near or west of the consensus at all times, leaning in the
direction of the HCCA corrected-consensus. I should mention that
if Wilfred intensifies more than expected, it would probably move a
bit right of the forecast track for a while due to the expected
southwesterly flow at higher levels, before eventually turning back
west-northwestward.
