01EONE.30kts-1006mb
Primer Invest de la temporada en el EPAC, y ya tenemos lío. A ver si actualiza el NHC sus avisos, por que de momento:
1. SHOWERS AND THUNDERSTORMS ASSOCIATED WITH A LOW PRESSURE SYSTEM
LOCATED ABOUT 625 MILES SOUTH-SOUTHWEST OF ACAPULCO MEXICO HAVE
BECOME MORE ORGANIZED OVERNIGHT...AND IT APPEARS THAT A TROPICAL
DEPRESSION COULD BE FORMING. IF THIS TREND CONTINUES...ADVISORIES
COULD BE INITIATED LATER TODAY. THIS SYSTEM HAS A HIGH CHANCE...80
PERCENT...OF BECOMING A TROPICAL CYCLONE DURING THE NEXT 48 HOURS.
Vamos a ver que hace la bicha. :)

¡Juer........! Si es que los han cogido "en bragas", sobre todo a la Navy. ¿Pues no que ponen en su página el track de un sistema en el Pacífico occidental, al Sur de Japón y Corea? :crazy:

:viejito:
Ya lo comentaba en mis últimos post, que quería arrancar en tiempo la temporada por el Pacífico Oriental. Ahí tenemos la 01E con tufo a Tormenta Tropical, ALVIN le toca.
Según el NHC Huracán en par de día camino a la nada de momento, aunque ahora el GFS a largo plazo parece que la quiere mandar de vuelta a Mexico, aunque eso es a muchos días.

Habemus TORMENTA TROPICAL ALVIN. ;D
TROPICAL STORM ALVIN DISCUSSION NUMBER 2
NWS NATIONAL HURRICANE CENTER MIAMI FL EP012013
200 PM PDT WED MAY 15 2013
ASCAT DATA FROM AROUND 1612 UTC SHOWED THAT THE DEPRESSION HAD WINDS
VERY NEAR THE THRESHOLD FOR A TROPICAL STORM. THE CLOUD PATTERN IN
VISIBLE IMAGERY HAS BECOME MORE ORGANIZED SINCE THE TIME OF THAT
PASS...AND IT IS LIKELY THAT THE SYSTEM HAS BECOME A TROPICAL
STORM. THE INTENSITY IS BEING SET AT 35 KT.
Saludos 8)

Tenemos a Alvin:
...DEPRESSION BECOMES FIRST TROPICAL STORM OF THE EASTERN PACIFIC SEASON...
35 kt 1005 hPa
Sigue teniendo muy buen aspecto, con topes nubosos altos. Tiene buenas posibilidades de superar los 50kt, incluso puede llegar a alcanzar fuerza de huracán durante unas horas, no es algo demasiado probable, pero las previsiones contemplan esa posibilidad.
PD: Jo qué velocidad, Rayo... ;D .
PPD: Parece que la cizalladura tiende a incrementarse hacia el noroeste, supongo que eso mermará sus posibilidades si no sigue organizando su circulación estas próximas 12-24 horas que es cuando tendrá el ambiente más favorable.
Un saludo. ;)

01EALVIN.45kts-1003mb-89N-1065W
En la discursión destacan que sigue fortaleciéndose, pero muy lentamente, debido la la cizalladura moderada del W que incide sobre el ciclón y que hace que la convección principal no esté bien acoplada al LLCC. Tiene tres dias de plazo para fortalecerse, pues pasado ese plazo, interactuaría con una fuerte vaguada y la cizalladura sería prohibitiva.

Cizallado a más no poder ::), y por si fuera poco, parece ser que se ha colado aire seco. El NHC ya no prevé que llegue a Huracán.

TROPICAL STORM ALVIN DISCUSSION NUMBER 6
NWS NATIONAL HURRICANE CENTER MIAMI FL EP012013
200 PM PDT THU MAY 16 2013
THERE IS SOME QUESTION WHETHER ALVIN STILL HAS A CLOSED LOW-LEVEL
CIRCULATION. THE STORM IS STILL FULLY EMBEDDED WITHIN THE ITCZ AND
IS SOMEWHAT DIFFICULT TO DISTINGUISH FROM ANOTHER CLUSTER OF DEEP
CONVECTION A FEW HUNDRED NAUTICAL MILES TO ITS SOUTHWEST. SINCE
THE SATELLITE APPEARANCE HAS WORSENED SINCE THIS MORNING...AND
DVORAK INTENSITY ESTIMATES ARE T3.0 FROM TAFB AND T2.5 FROM
SAB...THE INITIAL INTENSITY IS LOWERED TO 40 KT. THIS COULD BE
OVERLY GENEROUS.
ALVIN ACCELERATED A BIT THIS MORNING BUT HAS AN AVERAGE MOTION OF
285/10 KT. SINCE THE STORM HAS BEEN UNABLE TO DETACH ITSELF FROM
THE ITCZ...IT IS DOUBTFUL THAT ALVIN WILL MAKE MUCH NORTHWARD
PROGRESS. IN DIRECT CONTRAST TO YESTERDAY...THE TRACK GUIDANCE IS
NOW IN FULL AGREEMENT ON A GENERAL WEST-NORTHWESTWARD MOTION DURING
THE 5-DAY FORECAST PERIOD WITH VERY LITTLE SPREAD AMONG THE
INDIVIDUAL MODELS. THE UPDATED NHC TRACK FORECAST IS ESSENTIALLY
UNCHANGED FROM THE PREVIOUS ONE.
THE UW-CIMSS SHEAR ANALYSIS INDICATES THAT ALVIN IS BEING AFFECTED
BY 20-25 KT OF WESTERLY SHEAR...AND IT IS UNLIKELY THAT THE SHEAR
WILL ABATE DURING THE NEXT FEW DAYS. THE CURRENT STRUCTURE OF THE
STORM DOES NOT SUGGEST THAT STRENGTHENING IS LIKELY...AND THE NEW
NHC INTENSITY FORECAST HAS AGAIN BEEN LOWERED. THIS FORECAST
ESSENTIALLY FOLLOWS THE SHIPS...LGEM...AND FSU SUPERENSEMBLE MODELS.
ALVIN IS FORECAST TO DEGENERATE TO A REMNANT LOW IN ABOUT 4 DAYS.
HOWEVER...ADVISORIES COULD BE TERMINATED AT ANY TIME IF IT IS
DETERMINED THAT THERE IS NO LONGER A CLOSED CIRCULATION.
FORECAST POSITIONS AND MAX WINDS
INIT 16/2100Z 9.5N 109.1W 40 KT 45 MPH
12H 17/0600Z 9.8N 110.5W 40 KT 45 MPH
24H 17/1800Z 10.8N 112.0W 35 KT 40 MPH
36H 18/0600Z 11.5N 113.3W 35 KT 40 MPH
48H 18/1800Z 12.0N 114.7W 35 KT 40 MPH
72H 19/1800Z 13.0N 117.5W 30 KT 35 MPH
96H 20/1800Z 13.0N 120.0W 25 KT 30 MPH...POST-TROP/REMNT LOW
120H 21/1800Z 13.0N 122.5W 20 KT 25 MPH...POST-TROP/REMNT LOW
Comentan que es difícil distinguir a ALVIN del cualquier otro cluster convectivo de la ZITC, que entre que no ha podido separarse de esta y la cizalladura ha perdido mucha definición y que pudiera se degradado aun antes de lo pronosticado si no se puede definir su circulación en las próximas horas, la que es posible que haya perdido.

ALVIN es historia, no pudo separarse de la ZITC y la cizalla hizo el resto, bye bye ALVIN :sonrisa:
