...SMALL TROPICAL STORM FORMS IN THE NORTHEAST ATLANTIC...


SUMMARY OF 500 PM AST...2100 UTC...INFORMATION
----------------------------------------------
LOCATION...35.8N 32.2W
ABOUT 325 MI...525 KM WSW OF THE AZORES
MAXIMUM SUSTAINED WINDS...45 MPH...75 KM/H
PRESENT MOVEMENT...ESE OR 115 DEGREES AT 10 MPH...17 KM/H
MINIMUM CENTRAL PRESSURE...990 MB...29.24 INCHES


WATCHES AND WARNINGS
--------------------
There are no coastal tropical cyclone watches or warnings in effect.


DISCUSSION AND OUTLOOK
----------------------
At 500 PM AST (2100 UTC), the center of Tropical Storm Pablo was
located near latitude 35.8 North, longitude 32.2 West. Pablo is
moving toward the east-southeast near 10 mph (17 km/h), and this
motion is expected to continue tonight, followed by a gradual
turn toward the northeast and an increase in forward speed. On
this track, the small core of Pablo will pass near or over the
Azores this weekend.

Maximum sustained winds are near 45 mph (75 km/h) with higher gusts.
No significant change in strength is anticipated, and Pablo is
expected to become an extratropical cyclone in a couple of days to
the northeast of the Azores.

Pablo is a very small cyclone and its tropical-storm-force winds
extend outward up to 35 miles (55 km) from the center.

The estimated minimum central pressure is 990 mb (29.24 inches).


HAZARDS AFFECTING LAND
----------------------
Since Pablo is embedded within a large extratropical low, which
itself is forecast to bring strong winds to the Azores, the
Portuguese Institute for the Sea and Atmosphere (IPMA) has included
the effects of this small cyclone in their products. Those products
already account for the strong winds and high waves.

Tropical Storm Pablo Discussion Number   1
NWS National Hurricane Center Miami FL       AL182019
500 PM AST Fri Oct 25 2019

High-resolution visible satellite imagery gave us a surprise today.
A tropical cyclone has formed within a larger extratropical cyclone
in the northeastern Atlantic. This is not unique and has occurred
several times in the past, primarily during the latter part of the
hurricane season. Pablo is a very small-scale tropical cyclone, but
ASCAT data clearly show a well-defined but small circulation with
40-kt winds embedded within the larger low. This is the intensity
assigned to the cyclone for this advisory. The cloud pattern
consists of an eye-type feature surrounded by a ring of deep
convection. Given the small size of the cyclone, and the baroclinic
environment, the intensity forecast is highly uncertain. At this
time, the NHC forecast calls for a small increase in the winds and
for the cyclone to become extratropical in about 36 hours. However,
this transition could occur sooner than anticipated.

Pablo is currently moving toward the east-southeast at about 9 kt
while embedded within the circulation of the larger extratropical
low. Pablo should then turn toward the northeast with some increase
in forward speed, as indicated by the multi-model consensus aids.
In fact, all the models are in very good agreement, and the NHC
forecast is in the middle of the guidance envelope.

Given that Pablo is embedded within a large extratropical low,
which itself is forecast to bring strong winds to the Azores, the
Portuguese Institute for the Sea and Atmosphere (IPMA) has included
the effects of this small cyclone in their products. Those products
already account for the strong winds and high waves.

Tropical Storm Pablo Discussion Number   3
NWS National Hurricane Center Miami FL       AL182019
500 AM AST Sat Oct 26 2019

Pablo remains a small cyclone, and recently the eye-like feature
that was noted in earlier satellite images is no longer evident.
Since the system continues to have an area of deep convection
concentrated near the center, it should still be classified as a
tropical cyclone.  The current intensity is held at 40 kt, in
general agreement with the most recent estimate from TAFB, and
pending a new scatterometer overpass.  Pablo is embedded within a
much larger cyclonic circulation that is also producing gale-force
winds well to the north and northwest of the center.

The tropical storm is moving a little south of east at around 8 kt.
A turn toward the northeast and north is expected over the next
couple of days as Pablo moves around the periphery of a large
deep-layer trough over the eastern Atlantic   The official forecast
is a little faster than the previous one but slightly slower than
the latest corrected dynamical model consensus.

Some slight strengthening is possible during the next day or so
while Pablo moves through an environment that is unstable enough to
support deep convection.  However, by 36 hours the cyclone will be
passing over waters of 18 deg C or colder.  This should result in
the system becoming an extratropical low around that time.  In 2-3
days, the global models show the post-tropical low merging with
a larger low over the north Atlantic.

Given that Pablo is embedded within a large extratropical low,
which itself is forecast to bring strong winds to the Azores, the
Portuguese Institute for the Sea and Atmosphere (IPMA) has included
the effects of this small cyclone in their products.  Those products
already account for the strong winds and high waves expected in the
Azores.

Tropical Storm Pablo Discussion Number   4
NWS National Hurricane Center Miami FL       AL182019
1100 AM AST Sat Oct 26 2019

Pablo has changed little in organization since the last advisory.
The small cyclone is maintaining an area of banded convection near
the center, and there have been occasional appearances of an
eye-like feature.  Recent scatterometer overpasses show several wind
vectors of 40-45 kt, so the initial intensity is nudged upward to
45 kt.

The initial motion is now 090/14, a little faster than before.
Pablo is expected to turn northeastward during the next few hours,
with the small core of the storm passing near or over the eastern
Azores tonight.  After that, the tropical storm should turn
northward and eventually northwestward as it, as well as the
surrounding larger low pressure area, become steered by another
mid-latitude low pressure area developing over the north central
Atlantic.  The first 24 h of the new forecast track is adjusted
somewhat to the east of the previous track based on the initial
position and motion, with only small changes made thereafter.  The
new track lies near the various consensus models.

Little significant change in strength is expected during the next
24 h or so while Pablo moves through an environment that is unstable
enough to support deep convection.  After that time, colder sea
surface temperatures, increasing shear, and a developing frontal
zone near the cyclone should lead to the system becoming
extratropical.  The global models continue to forecast the system to
merge with the mid-latitude low to the west between 48-72 h, so the
intensity forecast shows dissipation during that time.

Given that Pablo is embedded within a large extratropical low,
which itself is forecast to bring strong winds to the Azores, the
Portuguese Institute for the Sea and Atmosphere (IPMA) has included
the effects of this small cyclone in their products.  Those products
already account for the strong winds and high waves expected in the
Azores.

Tropical Storm Pablo Discussion Number   5
NWS National Hurricane Center Miami FL       AL182019
500 PM AST Sat Oct 26 2019

Pablo has become a little better organized during the past several
hours, with a small eye becoming somewhat better defined.  However,
the various satellite intensity estimates have remained near 45 kt.
Based on the increased organization since the the 40-45 kt winds
seen in earlier scatterometer data, the initial intensity is now
set at 50 kt.

Pablo has turned northeastward and accelerated, with the initial
motion now 055/22.  This motion should bring the small core of the
storm near or over the eastern Azores during the next several hours.
 After that, the tropical storm should turn northward and eventually
northwestward as a developing mid-latitude low to the west becomes
the dominant steering mechanism.  The guidance has shifted a bit to
the east since the previous advisory, and the new forecast track is
similar to, but east of, the previous forecast.

Pablo should slow weaken as it moves into an environment of colder
sea surface temperatures and increasing shear, and a developing
frontal zone near the cyclone should lead to the system becoming
extratropical by 36 h.  The global models continue to forecast the
system to merge with the mid-latitude low to the west between
48-72 h, so the intensity forecast again shows dissipation during
that time.

Tropical Storm Pablo Discussion Number   7
NWS National Hurricane Center Miami FL       AL182019
500 AM AST Sun Oct 27 2019

Microwave satellite imagery indicates that Pablo has maintained a
small mid-level eye feature for at least the past 18 hours, and
the eye has also been evident in infrared imagery for the past 6
hours. The most recent Dvorak satellite intensity estimate was T3.0,
which was held down due to constraints even though the eye pattern
supports an intensity of 65 kt. Latest UW-CIMSS objective ADT and
SATCON intensity estimates are T4.4/75 kt and 64 kt, respectively.
Based on a blend of the TAFB and UW-CIMSS values, along with the
5- to 8-nmi-diameter eye, the intensity has been increased to 60 kt,
which could be conservative due to the the cyclone's relatively fast
forward speed.

Pablo has continued to accelerate and the initial motion estimate is
now 045/35 kt. The latest model guidance remains in good agreement
that during the next 48 hours, Pablo should slow down while making a
counter-clockwise track around the northeastern periphery of the
larger extratropical low that the small cyclone is embedded within.
The tightly packed guidance suite has shifted to the right of the
previous advisory track, and the new NHC forecast track has been
adjusted in that direction, close to the various consensus models.

Pablo is currently located over 20 deg C sea-surface temperatures
(SST), with colder water near 15 deg C ahead of the cyclone. Model
forecast soundings indicate that mid- and upper-level temperatures
will be warming, and when combined with the cooler SSTs, will result
in stabilization of the troposphere. This will cause convection to
steadily weaken and erode by 12 h, resulting in Pablo degenerating
into a post-tropical extratropical low pressure system in 24 h, if
not sooner. The small cyclone is forecast to dissipate or become
absorbed by the larger parent extratropical low in the 48-72 h
forecast period.

Hurricane Pablo Discussion Number   8
NWS National Hurricane Center Miami FL       AL182019
1100 AM AST Sun Oct 27 2019

Satellite imagery shows that Pablo has continued to maintain a
small eye, and that the eyewall cloud tops have recently cooled.
In addition, early morning microwave satellite intensity estimates,
as well as the CIMSS satellite consensus, indicate that Pablo has
become a hurricane.  The initial intensity is increased to 65 kt as
a blend between the subjective estimate from TAFB and the higher
SATCON estimate, and it is possible this is a little conservative.
The intensification has occurred while Pablo is over sea surface
temperatures of 19-20C, and it is likely that cold mid- to
upper-level air temperatures have allowed the cyclone to maintain
deep convection and strengthen over water temperatures where
tropical cyclones normally weaken.

The initial motion is now 030/28.  The cyclone is expected to turn
northward and slow its forward motion as it approaches a frontal
system to the north during the next 12-24 h, and this will be
followed by a turn toward the northwest as a large mid-latitude low
over the north central Atlantic becomes the main steering mechanism.
The track guidance has again shifted a little to the east, and the
new forecast track is also nudged a little to the east of the
previous track.  Like the previous forecast, it lies close to the
various consensus models.

Pablo should encounter even colder water along the forecast track,
and global model guidance suggests it should merge with the frontal
system between 12-24 h.  This combination should cause Pablo to
weaken and become an extratropical cyclone.  Thereafter, the system
should be absorbed by the much larger low to its west between 48-72
h.

Hurricane Pablo Discussion Number   9
NWS National Hurricane Center Miami FL       AL182019
500 PM AST Sun Oct 27 2019

Pablo continues to have a remarkably impressive appearance for a
tropical cyclone over such cold waters.  The hurricane's eye remains
evident in most satellite imagery channels, with a solid ring of
cloud tops colder than 50C surrounding it.  This maintenance of the
deep convection can be attributed to an environment of very cold
temperatures aloft, which can allow for the hurricane to remain
intact over waters colder than those typically observed. The latest
subjective Dvorak intensity estimate from TAFB remains unchanged
from 6 hours ago, while the objective estimates from UW-CIMSS have
increased slightly.  The initial advisory intensity has been
increased to 70 kt, and this could be a little conservative.

There are strong low-level easterlies associated with a baroclinic
zone and frontal boundary located a couple hundred miles north of
Pablo. The hurricane is expected to begin interacting with this zone
soon, which combined with even cooler waters should make the cyclone
lose its tropical characteristics within the next 24 hours. The
system is then expected to become absorbed by the circulation of a
much larger low as it approaches from the west in a couple of days.

The initial motion is now 020/20 kt. There is significant spread in
the model guidance beyond 24 hours, as the ECMWF and UKMET turn the
post-tropical cyclone to the northeast, while the remainder of the
guidance turns it northwest. The official forecast follows the
majority of the guidance and the previous forecast. In this
scenario, Pablo is expected to turn northward and slow its forward
motion tonight as it approaches the frontal zone. Then, a turn
toward the northwest on Monday is expected as the larger low to its
west begins to steer the cyclone.

Tropical Storm Pablo Discussion Number  10
NWS National Hurricane Center Miami FL       AL182019
1100 PM AST Sun Oct 27 2019

Shortly after the release of the previous advisory, deep convection
associated with Pablo finally began to decrease in both coverage and
organization.  Convection has become confined to the southern
portion of the circulation and the eye is no longer apparent in
conventional satellite imagery, although a low-level eye feature was
still noted in a recent GMI microwave overpass.  The initial
intensity has been reduced to 60 kt, which is a blend of the latest
Dvorak T- and CI-numbers from TAFB.

Pablo is approaching a frontal boundary that lies just to the north
of the cyclone, and is also moving over SSTs of around 17C. This
should cause the deep convection to continue to wane overnight, and
Pablo is expected to become extratropical when it merges with the
aforementioned front on Tuesday.  The global models indicate that
the post-tropical cyclone will be absorbed by a much larger
extratropical low to its west by Tuesday morning.

Recent microwave and satellite fixes show that Pablo's forward speed
has begun to slow as expected, and its initial motion is now north
or 360/12 kt.  The dynamical models indicate that Pablo will
continue to decelerate overnight as it moves generally northward.  A
slow northward motion should then continue on Monday as Pablo merges
with the frontal zone and becomes post-tropical.

The 12- and 24-h forecast wind radii were adjusted outward to
account for the area of gale-force winds north of the frontal
boundary that Pablo is expected to merge with late Monday or early
Tuesday.

Tropical Storm Pablo Discussion Number  11
NWS National Hurricane Center Miami FL       AL182019
500 AM AST Mon Oct 28 2019

Convection associated with Pablo has decreased significantly in both
coverage and vertical depth during the past 6 hours, and the system
barely meets the convective criterion to be classified as a tropical
cyclone. What bit of convection that does remain is limited to the
southeastern quadrant.  The advisory intensity of 45 kt is based on
a TAFB T-number classification of T3.0/45 kt and an earlier ASCAT
pass that showed some 45-kt vectors present in the southeastern
quadrant.

Pablo made a jog toward the northwest since the previous advisory,
but the small cyclone now appears to be moving slowly northward or
360/04 kt.  The latest model guidance remains in reasonable
agreement that Pablo and its remnants will move slowly northward
for the next day or so around the northeastern periphery of a large
extratropical centered several hundred miles to the southwest.
Pablo is expected to merge with the frontal zone and become
post-tropical later today.

Some additional weakening is likely during the next 24 hours due
to Pablo moving over even cooler sea-surface temperatures than the
16.5 deg C water that the cyclone is currently passing over.

Pablo's 34-kt wind radii have been separated from the larger parent
extratropical low's wind field based on late-arriving ASCAT surface
wind data that indicated that Pablo's small wind field a had
detached from the larger wind radii associated with the broad
extratropical low. Additional information on this complex low
pressure system can be found in High Seas Forecasts issued by the
NOAA National Weather Service High Seas Forecasts under AWIPS header
NFDHSFAT1, WMO header FZNT01 KWBC, and online at

Post-Tropical Cyclone Pablo Discussion Number  12
NWS National Hurricane Center Miami FL       AL182019
1100 AM AST Mon Oct 28 2019

Cold waters of 16C and increasing shear caused the deep convection
near Pablo's center to dissipate early this morning, and the
cyclone now consists of a swirl of low- to mid-level clouds and
showers. This lack of deep convection has caused Pablo to now
become post-tropical. A recent ASCAT pass showed an area of 30 to
35 kt winds northwest of the center of Pablo, and the initial
intensity is set to 35 kt based on those data. In addition, the
scatterometer data showed a much larger area of gale-force
winds well to the north of, but not directly associated with
Pablo.

The post-tropical cyclone will move slowly north to northwest over
the next day or so, until it is absorbed by a much larger
mid-latitude low to its west. The gales occurring north of the
Pablo are expected to persist at least until it is absorbed.
