TROPICAL STORM ZETA DISCUSSION NUMBER 18
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
4 PM EST TUE JAN 03 2006
BASED ON DVORAK CLASSIFICATIONS...AMSU INTENSITY ESTIMATES...AND THE
GENERAL APPEARANCE OF THE SYSTEM ON SATELLITE IMAGES...ZETA HAS NOT
STRENGTHENED OVER THE PAST SEVERAL HOURS. IN FACT THE CENTRAL
CONVECTION HAS WEAKENED AND THE CLOUD PATTERN HAS BECOME A LITTLE
RAGGED-LOOKING. DVORAK T-NUMBERS CONTINUE TO SUPPORT AN INTENSITY
OF 45 KT. THERE IS AN UPPER-LEVEL TROUGH PRACTICALLY SUPERIMPOSED
ON THE STORM AT THIS TIME. THIS TROUGH SHOULD CONTINUE TO MOVE
EASTWARD...AND STRONG NORTHWESTERLY FLOW IN ITS WAKE IS LIKELY TO
BEGIN TO DISRUPT THE SYSTEM IN 12-24 HOURS.
SO...ALTHOUGH YOU'VE
HEARD THIS FROM US BEFORE...WE EXPECT A WEAKENING TREND TO COMMENCE
TOMORROW.INITIAL MOTION IS WESTWARD...270/4. THERE HAS BEEN LITTLE CHANGE TO
THE TRACK FORECAST REASONING FROM THE PREVIOUS ADVISORY. ZETA
SHOULD BE STEERED GENERALLY WESTWARD BY THE FLOW ON THE SOUTH SIDE
OF A LOW-LEVEL RIDGE FOR THE NEXT DAY OR SO. THEN...A GRADUAL TURN
TO THE RIGHT IS ANTICIPATED IN RESPONSE TO THE APPROACH OF A LARGE
LOW PRESSURE SYSTEM.
IF ZETA WEAKENS FASTER THAN INDICATED
HERE...IT WOULD PROBABLY FOLLOW A MORE WESTWARD TRACK IN 3-4 DAYS.FORECASTER PASCH

Viene a decir que no ha aumentado su conveccion y que, de hecho, parece que se ha desorganizado la "nube" que lo acompaña... dice que fuertes vientos del oeste en altura estan practicamente encima de Zeta y que pueden acbar con el sistema en 12 o 24 horas...
(en negrita) aunque usted haya oido esto antes de nosotros, el debilitamiento esta cerca ... ahora debe dirigirse al oeste por los vientos en superficie que esta encontrando en su parte sur y lego girar mas por el acercamiento de una borrasca...
(en negrita) si Zeta resiste esto probablemente tendra camino libre al oeste durante 3 o 4 dias mas...
