Brutal ese paso por Bermuda...
Ha tenido que ser desastroso para la isla, se ha comido el Huracán de cabo a rabo. Y esa imagen del Ojo con la isla en medio es espectacular. Pero más espectacular se ha tenido que ver desde la propia isla.

Genial seguimiento y muchas gracias!!

El huracán #Nicole sigue debilitándose y perdiendo fuerza cayendo a #Cat1 con vientos de 138 Km/h ya en el paralelo 36
Se aprecia su dispersión.

Pues esa imagen era preludio de cómo NICOLE se iba y está resistiéndose a perder su naturaleza tropical... De hecho, se prevé que vuelva a ser un huracán hoy... 8) :P

TROPICAL STORM NICOLE DISCUSSION NUMBER  45
NWS NATIONAL HURRICANE CENTER MIAMI FL       AL152016
500 AM AST SAT OCT 15 2016

The cloud pattern has not changed much since the last advisory.
Patches of deep convection keep reforming near and to the north of
the center. The circulation appears to be elongated, but it is still
well defined. Initial intensity is kept at 60 kt.

As mentioned by my predecessor, the future structure of Nicole is
difficult to forecast
. Given the strong shear and cold SSTs, one
should tend to foreast weakening or extratropical transition.
However, both the GFS and the ECMWF simulated infrared imagery
continue to forecast the development of an eye feature in a day or
so.
Given these model solutions, the NHC forecast keeps Nicole with
tropical characteristics during the next 3 days and calls for the
cyclone to become post-tropical thereafter.

After an increased in forward speed last evening, Nicole has slowed
down a little, and is now moving toward the east-northeast at about
15 kt. The cyclone is already embedded within a mid-latitude trough
and will continue to move with the trough on the same general track
with a decrease in forward speed for the next 2 to 3 days. After
that time, another trough will approach Nicole and will probably
kick the cyclone toward the north-northeast. The NHC forecast is in
the middle of the guidance envelope and is not different from the
previous one.

Guidance from the NOAA Ocean Prediction Center was used for the
forecast wind radii.

Swells from Nicole will affect Bermuda and portions of the U.S. east
coast and Atlantic Canada during the next couple of days.  By early
next week, wave models suggest that long-period swell from Nicole
will radiate outward and affect much of the North Atlantic basin.

Los diagramas de fase basados en el UKMO son impresionantes... en base a esos pronósticos de reintensificación como huracán, el UKMO apuesta por una profundización muy intensa. A ver qué hace finalmente.

#Nicole se parece mas a una borrasca #Atlántica por su forma de 9 o coma, que a un huracán, aunque al fin de cuentas, ambos son un #Ciclón

La verdad es que es un caso extraordinario, precioso............. :o :o :o

¿Dónde has visto que haya recuperado el estatus de huracán? Porque no veo que el CNH haya actualizado su abanico de productos sobre NICOLE...

HURRICANE NICOLE DISCUSSION NUMBER  46
NWS NATIONAL HURRICANE CENTER MIAMI FL       AL152016
1100 AM AST SAT OCT 15 2016

Nicole has intensified since the last advisory, likely due to
baroclinic influences from a nearby upper-level trough.
Just-received ASCAT-B data shows 70-75 kt winds to the southwest of
the center, and a drifting buoy south of the center reported a
pressure 966.6 mb at 1000 UTC, suggesting a falling
central pressure.  Based on these data, the intensity is increased
to 75 ktIt should be noted that the cloud pattern has some
characteristics of a subtropical cyclone due to the cyclone's
interaction with the upper-level trough
.

The GFS and the ECMWF continue to forecast organized central
convection for the next 48 hours or so, indicating that Nicole is
likely to maintain tropical cyclone characteristics despite cooler
air entraining into the circulation. After that time, the cyclone
should move over sea surface temperatures of 16 deg C or less that
should cause the central convection to dissipate. Based on this, the
intensity forecast calls for Nicole to become post-tropical by 72
hours and then fully extratropical by 96 hours. The new intensity
forecast is adjusted upward for the first 12 hours based on the
current intensity, and after that it is an update of the previous
forecast.  Overall, the forecast lies near the upper end of the
intensity guidance.

Nicole appears to be slowing its forward motion, and the motion
estimate is now 075/11.  A slow easterly motion is expected during
the next 36 hours or so while the cyclone is an area of weaker flow
in the mid-latitude westerlies.  After that time, a large
mid-latitude trough moving into eastern Canada should steer the
cyclone north-northeastward with an increase in forward speed.  The
new forecast track is again similar to the previous track and lies
near the various consensus models.

Guidance from the NOAA Ocean Prediction Center was used for the
forecast wind radii.

Swells from Nicole will affect Bermuda and portions of the U.S. east
coast and Atlantic Canada during the next couple of days.  By early
next week, wave models suggest that long-period swell from Nicole
will radiate outward and affect much of the North Atlantic basin.

HURRICANE NICOLE DISCUSSION NUMBER  47
NWS NATIONAL HURRICANE CENTER MIAMI FL       AL152016
500 PM AST SAT OCT 15 2016

Nicole is currently showing a hybrid structure.  On the larger
scale, the system has the appearance of an extratropical low, with
cold air advection occurring over the southern semicircle and a
developing frontal cloud band east through south of the center.
However, the system has secluded an area of warm air near the
center where a tropical cyclone wind and temperature structure
exists. The earlier scatterometer overpass showed the radius of
maximum winds to be about 75 n mi, and the warm core is strong
enough to produce hurricane-strength AMSU intensity estimates.
Based on little change in the appearance of the cloud pattern since
the last advisory, the intensity is held at 75 kt.

The GFS and the ECMWF continue to forecast organized central
convection for the next 36-48 hours, indicating that Nicole is
likely to maintain tropical cyclone characteristics.  After that
time, the cyclone should move over sea surface temperatures of 16
deg C or less that should cause the central convection to dissipate.
Based on this, the intensity forecast calls for Nicole to become
post-tropical by 72 hours and then fully extratropical by 96 hours.
The latest dynamical model guidance forecasts the cyclone to be
absorbed by another extratropical low by 120 hours, and that is now
reflected in the intensity forecast.  The new forecast is otherwise
an update of the previous forecast.

The initial motion is now 075/10.  A slow easterly motion is
expected during the next 36 hours or so while the cyclone is in an
area of weaker flow in the mid-latitude westerlies.  After that
time, a large mid-latitude trough moving into eastern Canada should
steer Nicole north-northeastward with an increase in forward speed.
The new forecast track is again similar to the previous track and
lies near the various consensus models.

Guidance from the NOAA Ocean Prediction Center was used for the
forecast wind radii.

Swells from Nicole will affect Bermuda and portions of the U.S. east
coast and Atlantic Canada during the next couple of days.  By early
next week, wave models suggest that long-period swell from Nicole
will radiate outward and affect much of the North Atlantic basin.
