Ya tenemos aquí a la tormenta SUBtropical ANA... que podría transicionar a tormenta tropical pura durante el día de hoy. Ya se observa cómo se va desprendiendo del sistema de frentes

Viendo la evolución de ANA en las últimas horas, creo que pronto será tormenta TROPICAL...

Wow... Se está nutriendo de las aguas cálidas de la corriente del golfo, sin duda... Me resulta bastante chocante la evolución de hoy de ANA...

TROPICAL STORM ANA DISCUSSION NUMBER   7
NWS NATIONAL HURRICANE CENTER MIAMI FL       AL012015
1100 AM EDT SAT MAY 09 2015

Deep convection has increased somewhat near the center of the
storm, and SFMR observations from the Air Force Hurricane Hunters
continue to support an intensity of 50 kt.  Ana will be moving
over the cooler waters to the northwest of the Gulf Stream later
today, and water vapor imagery shows a belt of upper-level
northerly flow advancing toward the tropical cyclone.  The
decreasing sea surface temperatures and increasing northerly shear
should cause Ana to weaken as it nears the coast.  The official
intensity forecast is similar to that from the previous package,
and very close to the latest intensity model consensus, IVCN.

The initial motion estimate is 320/3.  The track forecast reasoning
remains basically unchanged from the past few advisories.  Global
models continue to predict that the blocking mid-level ridge to the
north of Ana will shift eastward and weaken over the next couple of
days.  These models also show a broad trough moving from the central
to the eastern U.S. over the next 72 hours or so.  This should
result in the cyclone turning northward and north-northeastward with
a gradual increase in forward speed.  The official track forecast is
similar to the previous one and in good agreement with the latest
dynamical model consensus, TVCN.
