Hace días que los modelos mostraban desarrollo en el Pacífico Oriental y al final ha sucedido. Tenemos a la Tormenta Tropical CRISTINA a  casi 800 Km al SW de México avanzando de momento a aguas de nadie.

En la discusión nos cuentan que a pesar de tener algo de cizalladura del NE de momento las condiciones pronto mejorarán y con aguas muy cálidas, baja cizalladura  y alta humedad CRISTINA debe pegar un buen levantón en los próximos 1-2 días pudiendo llegar a Major en 72 horas, lo que con un rumbo entre el WNW y el NW a partir de ahí  estaría moviéndose hacía un ambiente mas estable y aguas menos cálidas lo que haría que CRISTINA comenzará a debilitarse en los días 4 y 5.

Saludos

CRISTINA ha ganado en intensidad pero no como se esperaba.

...CRISTINA CONTINUING AS A TROPICAL STORM WELL OFFSHORE THE COAST
OF MEXICO...


SUMMARY OF 300 PM MDT...2100 UTC...INFORMATION
----------------------------------------------
LOCATION...16.0N 107.7W
ABOUT 305 MI...490 KM SW OF MANZANILLO MEXICO
MAXIMUM SUSTAINED WINDS...60 MPH...95 KM/H
PRESENT MOVEMENT...NW OR 315 DEGREES AT 13 MPH...20 KM/H
MINIMUM CENTRAL PRESSURE...998 MB...29.47 INCHES

Durante el día de hoy aunque la convección se ha incrementado  el centro ha estado en par de ocasiones expuesto debido a la cizalladura del NE que no acaba de ceder aunque ya debía, por la misma causa el desarrollo de las bandas espirales es pobre, en especial en el semicírculo norte de la circulación.

Como ha demorado el desarrollo pero el llegar a aguas mas frías y ambiente estable sigue en tiempo (ahora a unas 48 horas)pues ya el NHC no le ve llegando a Major y comenzando a debilitarse en 36-48 horas, probablemente se disipe en unos 4 o 5 días.

Saludos

....CRISTINA casi es huracán.

Casi huracán y es probable que lo logre antes de comenzar a debilitarse a partir de mañana en la noche (unas 24 horas) a partir de que la temperatura superficial del mar por donde se desplazará bajará de los 26ºC necesarios para mantener la convección. Entre 72 y 96 horas CRISTINA será historia.

Saludos

Pues no lo ha logrado, hoy todo el día ha estado cerca pero ya en su última discusión el NHC comenta que es aspecto de CRISTINA se ha degradado durante la tarde producto de moverse sobre aguas mas frías. A partir de ahora a CRISTINA solo le queda ir debilitándose progresivamente hasta llegar a baja remanente en unas 72 horas.

En efecto CRISTINA nunca logró se huracán y ya se debilita a marchas forzadas, moverse sobre aguas cada vez mas frías con aire estable y seco por delante prácticamente le han hecho perder casi toda la convección cerca del centro y la intensidad desciende a apenas 40KT (unos 75 km/h). El NHC le da apenas 24h y pudieran ser menos aun.

CRISTINA es un precioso remolino de nubes bajas y medias entrando en un mar de stratocumulos, sus vientos sostenidos  han descendidos al mínimo de tormenta tropical (35 nudos o 65 Km/h) le quedan unas 12 horas a lo sumo de seguimiento.
