Animación de la perturbación, sin desperdicio...
Vamos a consultar los campos de cizalladura del viento, a ver cómo andan, aunque a priori viendo la imagen de vapor de agua, esa perturbación está ubicada en una zona de baja cizalladura.
MODIFICO: los mapas indican una alta cizalladura...

Ojo al dato en el seguimiento que estamos haciendo en Caza. El forero Vigorro ha puesto allí una discusión sobre la perturbación, presumiblemente del NHC, indicando que la perturbación se estaba haciendo tormenta tropical, y es que las imágenes no engañan

TROPICAL STORM ZETA SPECIAL DISCUSSION NUMBER 1
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
NOON EST FRI DEC 30 2005
AN ELONGATED AREA OF LOW PRESSURE...WHICH HAD ITS ORIGINS IN AN OLD
FRONTAL TROUGH...BEGAN DEVELOPING ORGANIZED CONVECTION OVERNIGHT.
WITH WELL-FORMED CONVECTIVE BANDS NEAR THE CENTER...WEAK
ANTICYCLONIC OUTFLOW ALOFT...AND TROPICAL DVORAK CLASSIFICATIONS...
ADVISORIES ARE INITIATED ON THE 27TH TROPICAL STORM OF 2005. THE
INTIAL INTENSITY OF 45 KT IS A COMPROMISE BETWEEN THE RULE-
CONSTRAINED T2.5 CLASSIFICATIONS AND THE T3.5 DATA T NUMBERS.
WITHIN 24 HOURS...WESTERLY SHEAR IS EXPECTED TO INCREASE SHARPLY
OVER THE CYCLONE...SO ZETA PROBABLY HAS A SHORT LIFE AHEAD OF IT.
THE INITIAL MOTION IS 305/7...AS ZETA IS MOVING AROUND A MID-LEVEL
LOW TO ITS SOUTHWEST. THE FORWARD SPEED IS EXPECTED TO SLOW AS THE
WESTERLIES BEGIN TO IMPINGE ON THE CYCLONE WITHIN 12-24 HOURS.
AFTER THAT...IF THE SYSTEM WEAKENS IN RESPONSE TO THE SHEAR...IT
SHOULD TURN WESTWARD WITH THE LOW-LEVEL FLOW. THE OFFICIAL
FORECAST IS A BLEND OF THE MEDIUM AND SHALLOW BAM MODELS...AND IS
SOMEWHAT SLOWER TO THE WEST THAN THE GFS GUIDANCE.
