NWS NATIONAL HURRICANE CENTER MIAMI FL       EP012012
800 PM PDT FRI MAY 18 2012

ALETTA HAS ONE WEAKENING PATCH OF DEEP CONVECTION TO THE NORTHEAST
OF THE LOW-LEVEL CENTER SO IT STILL QUALIFIES...ALBEIT BARELY...AS
A TROPICAL CYCLONE AT THIS TIME.  BASED ON DVORAK
CLASSIFICATIONS...THE INTENSITY IS LOWERED TO 25 KT.  CONTINUED
STRONG SHEAR AND THE ENTRAINMENT OF DRY MID-TROPOSPHERIC AIR...AS
SEEN IN TOTAL PRECIPITABLE WATER IMAGERY...SHOULD LEAD TO THE
DEMISE OF THE SYSTEM AS A TROPICAL CYCLONE BY TOMORROW.

THE CYCLONE CONTINUES TO MOVE SLOWLY NORTHEASTWARD...045/03...IN A
REGION OF WEAK STEERING CURRENTS.  OVER THE NEXT COUPLE OF DAYS THE
TROPICAL CYCLONE OR REMNANT LOW SHOULD TURN EASTWARD...AND THEN
SOUTHWARD UNDER THE INFLUENCE OF A DISTURBANCE TO THE EAST.  THE
OFFICIAL FORECAST IS SIMILAR TO THE PREVIOUS ONE AND IS CLOSE TO
THE DYNAMICAL MODEL CONSENSUS.
