Buenos Dias: A la verdad no entiendo los nuevos dizque "productos"para esta temporada 2017 . Historicamente un sistema con vientos sostenidos de 35 MPH era clasificado como depresion tropical y ya con vientos sostenidos de 40mph como tormenta. Pero ahora se le llama "potential cyclone alert".Si entiendo bien, esto reduciria la cantidad de tormentas con nombres en la temporada, pues en este momento este sistema conocido como "two" (2) tiene vientos sostenidos de 40mph y no tiene nombre aun
Para el que sepa la razon de este cambio perdone mi ignorancia. Pero debe existir alguna razon de peso para esta transformacion en la meteorologia tropical conocida hasta hoy.

No afecta el número de sistemas nombrados. Lo de "Potential Tropical cyclone" es otro nombre para un Invest pero con alto % de desarrollo.

Si ese nuevo término no hubiese entrado al juego, este sistema seguiría siendo in Invest. Recuerda que para clasificar como depresión o tormenta, no solamente hacen falta los vientos, se necesita cierta estructura y una circulación completamente cerrada. Esa última es lo que le falta todavía a este Invest/Potential Tropical Cyclone.

El efecto de este nuevo término es solo que se emite un boletín oficial con trayectoria y de ser necesario, avisos y vigilancias.

through the Windward Islands and eastern Venezuela tonight and
Tuesday.

Thunderstorm activity associated with the disturbance continues to
show signs of organization, and additional development is likely
during the next day before the system interacts with Venezuela.
* Formation chance through 48 hours... high...80 percent
* Formation chance through 5 days...high...80 percent

Tropical-storm-force winds extend outward up to 70 miles (110 km)
from the center.

The estimated minimum central pressure is 1005 mb (29.68 inches).


HAZARDS AFFECTING LAND
----------------------
WIND: Tropical storm conditions are expected to first reach
portions of the warning area tonight, making outside preparations
difficult or dangerous.

accumulations of 2 to 4 inches over the Windward Islands and the
eastern coast of Venezuela tonight and Tuesday.


NEXT ADVISORY

Tropical Storm Bret Discussion Number 5
NWS National Hurricane Center Miami FL AL022017
500 PM AST Mon Jun 19 2017

An Air Force WC-130 invest mission this afternoon into the
disturbance was able - after much effort - to find a well-defined
closed circulation. The location of the center was substantially
farther west than anticipated, as the system is now moving toward
the west-northwest at a very quick 26 kt. Because the system
has developed a well-defined center, it is now considered a tropical
storm and has been named Bret.

Convection continues to display robust bands on the northwestern
and southeastern quadrants of the disturbance, as seen in the
geostationary satellite and Trinidad radar imagery. The Hurricane
Hunter mission also found maximum surface winds of about 35 kt,
which agrees with the Dvorak 2.5 CI number from TAFB. These winds
are only occurring in the northern semicircle due to the very quick
translational velocity of the system.

While the convective structure has been impressive today, it
appears that the window of opportunity for the system to
further develop is closing. Between interaction with the landmass
of Venezuela and increasing vertical shear beginning in about a day,
the intensity model guidance does not show any significant
intensification. The official intensity forecast is steady state
for about a day, followed by gradual weakening until dissipation in
about three days. An alternative scenario - given that the
disturbance has tracked left, or equatorward, of the guidance thus
far - is that it could remain south of the forecast track and
dissipate over Venezuela and never reach the Caribbean Sea.

The system is anticipated to slow somewhat, but still move at a
rapid rate toward the west-northwest until dissipation, steered by
strong trade winds south of the Bermuda high. The official track
forecast is based upon the HCCA corrected consensus technique and is
faster compared with the previous advisory, due to the farther west
initial position.


FORECAST POSITIONS AND MAX WINDS

INIT 19/2100Z 9.4N 59.8W 35 KT 40 MPH
12H 20/0600Z 10.1N 62.1W 35 KT 40 MPH

Saludos a todos nuevamente en otra temporada de huracanes y mas temprano que en otras ya con disturbios viniendome del pasillo del Africa. Pregunta que es ESO de que ahora le llaman Potential Tropical Cyclone a Los disturbios aun teniendo 40 MPH. En mis tiempos ESO ya era tormenta tropical. Gracias por la orientación.
