Tropical Storm Helene Discussion Number 5
NWS National Hurricane Center Miami FL AL082018
1100 AM AST Sat Sep 08 2018

The structure of Helene continues to improve, with convective
banding wrapping around almost completely around the center of the
cyclone in visible satellite imagery. Infrared imagery suggests
this convection is not very strong at the moment, though, and this
may be why recent scatterometer data indicates that the storm has
not strengthened since the last advisory. The initial intensity
remains 40 kt based on the scatterometer winds.

All indications are that Helene should strengthen through at least
72 h in a light vertical shear environment over sea surface
temperatures near 27C. This part of the intensity forecast is
similar to the previous forecast and lies near the intensity
consensus. However, there are a couple of alternate forecast
scenarios. The first is that Helene could rapidly intensify and
become stronger than currently forecast. The second is that a
large plume of African dust and associated dry air that has spread
over the northern Cabo Verde Islands starts entraining into the
cyclone and inhibits intensification. The former alternative seems
more likely than the latter at this time, and if RI begins later
intensity forecasts will need to be increased. After 72 h, Helene
is expected to encounter increasing southwesterly shear associated
with a mid- to upper-level trough over the central Atlantic, which
should cause the system to weaken.

Helene's center appears to have again re-formed, this time a little
to the south. The somewhat uncertain initial motion is 265/11.
Other than a slight nudge to the south due to the initial position,
there is little change in the forecast track for Helene. The
cyclone should moved westward to west-northwestward for the next
3-4 days on the south side of the subtropical ridge, then turn
northwestward in response to the aforementioned trough.

Thats a long ass flight to measure a storm that wont meaningfully impact land after Sunday for a week (and probably never). All just to get it declared a TS a few hours early?


It's already a TS, and if they would do it they would get so much valuable data that could be put into the computers. It would help with all the storms out there right now. Also Helene will be hitting landfall in the next 36 hours.


Likely won’t be landfalling anywhere, will just scrape the islands to the south. And I agree it’s meaningless to send recon all the way across the Atlantic. One, tax money isn’t unlimited, and two, they are preoccupied with Florence and Olivia at the moment.

Otherwise, Helene is starting to get together and is taking a path similar to Florence in the short term. But I’m pretty sure this will be a storm to possible harass the Azores. We’ll see though.

None.

SUMMARY OF WATCHES AND WARNINGS IN EFFECT:

A Hurricane Watch is in effect for...
* The Cabo Verde islands of Santiago, Fogo, and Brava

A Tropical Storm Warning is in effect for...
* The Cabo Verde islands of Santiago, Fogo, and Brava

A Hurricane Watch means that hurricane conditions are possible
within the watch area, in this case within the next 24 to 36 hours.

A Tropical Storm Warning means that tropical storm conditions are
expected somewhere within the warning area, in this case within the
next 24 to 36 hours.

For storm information specific to your area, please monitor
products issued by your national meteorological service.


DISCUSSION AND OUTLOOK
----------------------
At 200 PM AST (1800 UTC), the center of Tropical Storm Helene was
located near latitude 13.4 North, longitude 21.1 West. Helene is
moving toward the west near 13 mph (20 km/h), and this general
motion will likely continue through Sunday. A gradual turn toward
the west-northwest with an increase in forward speed is expected
Sunday night through Tuesday. On the forecast track, Helene will
pass very close to the southern Cabo Verde Islands tonight and early
Sunday.

Maximum sustained winds have increased to near 50 mph (85 km/h) with
higher gusts. Satellite imagery indicates that Helene is becoming
better organized, and strengthening is forecast for the next couple
of days. Helene is expected to become a hurricane on Sunday or
Sunday night.

Tropical-storm-force winds extend outward up to 60 miles (95 km)
from the center.

The estimated minimum central pressure is 1001 mb (29.56 inches).


HAZARDS AFFECTING LAND
----------------------
WIND: Tropical storm conditions are expected to first reach the
warning area tonight or early Sunday. Hurricane conditions are
possible in the southernmost Cabo Verde Islands on Sunday.

RAINFALL: Helene is expected to produce total rain accumulations of
3 to 5 inches over the southern Cabo Verde Islands through Sunday,
with isolated maximum amounts of 8 inches. This rainfall may produce
life-threatening flash floods.


NEXT ADVISORY
-------------
Next complete advisory at 500 PM AST.

Tropical Storm Helene Discussion Number 6
NWS National Hurricane Center Miami FL AL082018
500 PM AST Sat Sep 08 2018

During the past few hours, Helene has developed a convective band
that wraps about three-quarters of the way around the storm, and
the intensity of the inner core convection has increased. In
addition, microwave imagery shows an elliptical inner ring feature.
Satellite intensity estimates at 18Z were in the 35-50 kt range, and
given the recent increase in organization the initial intensity is
increased to 50 kt.

Helene should continue to strengthen through at least 72 h in a
light vertical shear environment over sea surface temperatures near
27C. This part of the intensity forecast has been increased over
the previous forecast and lies near the intensity consensus.
However, there remain a couple of alternate forecast scenarios. The
first is that Helene could rapidly intensify and become stronger
than currently forecast, and the rapid intensification index of the
SHIPS model has about a 35 percent chance of 25 kt of strengthening
in the next 24 h. The second is that a large plume of African dust
and associated dry air that has spread over the Cabo Verde Islands
starts entraining into the cyclone and inhibits intensification.
The former alternative is more likely than the latter at this time.
After 72 h, Helene is expected to encounter increasing southwesterly
shear associated with a mid- to upper-level trough over the central
Atlantic, which should cause the system to weaken significantly.

The initial motion is 275/11. There again is little change in the
forecast guidance or the forecast track, with Helene expected to
move westward to west-northwestward for the next 3 days or so on the
south side of the subtropical ridge, then turn northwestward in
response to the aforementioned trough.

Tropical Storm Helene Discussion Number 7
NWS National Hurricane Center Miami FL AL082018
1100 PM AST Sat Sep 08 2018

Helene continues this evening with a large area of convective
bands that wrap about three-quarters around the center. A blend of
the subjective Dvorak classifications from TAFB and SAB with
the CIMSS' SATCON gives an intensity of 50 kt, unchanged from the
previous advisory. The tropical storm is situated just south of the
upper-level subtropical ridge, which is inducing weak southeasterly
vertical shear. That along with warm 28C waters and a moist,
unstable atmosphere should support at least steady intensification
for the next two days. By day three, however, the shear will
increase out of the southwest as Helene moves close to an
upper-level low. Simultaneously, the SSTs will drop to near 26C and
the mid-troposphere should dry. The new intensity forecast shows a
peak of 90 kt at 48 h, with gradual to steady weakening thereafter.
This is based upon the IVCN multi-model consensus (minus the
much weaker HMON solution) with a higher peak intensity than the
previous advisory but a slightly faster decay.

Helene's initial position was aided by the availability of a 2222Z
ASCAT pass, which showed it to be somewhat farther south than
earlier estimated. The initial motion is analyzed to be 260/11,
as it is steered by a deep-layer ridge to its north. The
tropical cyclone should gradually turn toward the west-northwest by
Monday, then toward the north-northwest by Wednesday. The new
track forecast - based on the TVCN multimodel consensus - is
slightly south of the previous advisory throughout the forecast
period, mainly because of the southward initial position.

The aforementioned scatterometer pass allowed for a more accurate
assessment of the initial size, which is somewhat larger than
analyzed earlier. The new wind radii prediction indicates a larger
Helene than the previous advisory, and is based upon the RVCN
multi-model consensus.

Tropical Storm Helene Discussion Number 8
NWS National Hurricane Center Miami FL AL082018
500 AM AST Sun Sep 09 2018

Satellite imagery indicates that Helene continues to become better
organized with an increase in banding overnight. A couple of
recent microwave images show that the inner core continues to
organize with a low-level ring evident and indication that a
banding-type eye is forming. Dvorak satellite T-numbers have
increased and support an initial intensity of 55 kt.

Helene is forecast to remain over SSTs of 27-28C during the next
couple of days. The upper-level wind pattern is also expected to
be quite favorable, and these conditions should support steady
intensification. Slightly cooler waters and increasing
southwesterly shear from an upper-level trough to the northwest of
Helene are likely to put an end to the intensification process by
day 3. After that time, Helene is forecast to move closer to the
aforementioned trough with southwesterly shear and drier mid-level
air likely to result in weakening by day 4 and 5. The NHC intensity
forecast is near the IVCN intensity consensus model, but it is a
little more conservative than the FSSE and HCCA models.

The tropical storm is moving westward or 270 degrees at 12 kt. A
deep-layer ridge to the north of the storm should steer Helene
westward to west-northwestward during the next couple of days. By
mid-week, Helene is expected to approach a weakness in the ridge
between 40-50W longitude and the cyclone is predicted to turn
northwestward, then north-northwestward by the end of the period.
The track guidance is in fairly good agreement on this scenario,
but there is some spread later in the period as to exactly what
longitude the northwesterly turn takes place. The NHC forecast is
between the various dynamical model solutions and is close to the
HFIP corrected consensus model.

Tropical Storm Helene Discussion Number 9
NWS National Hurricane Center Miami FL AL082018
1100 AM AST Sun Sep 09 2018

Helene continues to exhibit a fairly well-organized cloud pattern,
but does not yet have a well-defined inner core. The current
intensity estimate, 55 kt, is based on a blend of subjective and
objective Dvorak estimates and is also close to the latest SATCON
value. The tropical cyclone is expected to remain over warm waters
with low to moderate vertical wind shear for the next couple of
days. Therefore, strengthening is likely through the early part of
this week. Later in the period, marginal SSTs and increasing
south-southwesterly shear should induce weakening. The official
wind speed forecast is on the high side of the numerical intensity
guidance.

Helene continues to move westward, or about 270/11 kt. The system
should move westward to west-northwestward to the south of a
mid-level ridge over the eastern Atlantic over the next 48 hours or
so. Thereafter, a mid-level trough is expected to create a
pronounced weakness in the ridge along 40W-45W longitude. This
steering pattern is likely to cause Helene to turn northwestward to
north-northwestward during the latter part of the forecast period.
The official track forecast is very similar to the previous NHC
prediction and lies roughly in the middle of the numerical guidance
suite.

Trying its best to break out of the shadows. But it will have to rapidly intensify to a major fast to get any attention, kinda reminding me of Julia 2010.

Hurricane Helene Discussion Number 10
NWS National Hurricane Center Miami FL AL082018
500 PM AST Sun Sep 09 2018

Deep convection has increased in coverage and intensity over the
southern portion of the circulation, and microwave imagery suggests
that an inner core is beginning to develop. Helene's maximum
winds are boosted to hurricane strength, 65 kt, based on Dvorak
Current Intensity numbers from SAB and TAFB. The cyclone should
continue to traverse warm waters and be in a low-shear environment
for the next couple of days. Therefore, additional intensification
is called for during the next 48 hours. Afterwards, increasing
south-southwesterly shear should cause gradual weakening. The
official intensity forecast is close to the model consensus, IVCN.

Helene is moving just north of due west, or 280/11 kt. There are no
significant changes to the track forecast philosophy for this
advisory. Helene should move generally west-northwestward along
the south side of a weak mid-level ridge for the next couple of
days. After that, a mid-level trough digging along 40W-45W
longitude should induce a turn toward the northwest and eventually
north. The official track forecast is very similar to the one from
the previous cycle through 72 hours, and is nudged a little to the
east after that time. This is fairly close to the latest corrected
consensus guidance, HCCA.

FORECAST POSITIONS AND MAX WINDS

INIT 09/2100Z 13.4N 26.0W 65 KT 75 MPH

I do believe she will get to Major, just don't know if she will make the complete loop over the open water or go into Spain/Portugal. If it makes the complete loop who knows what she will do .
