TROPICAL DEPRESSION ONE-E DISCUSSION NUMBER   1
NATIONAL WEATHER SERVICE MIAMI FL
2 PM PDT FRI MAY 24 2002

SATELLITE IMAGES INDICATE THAT THE AREA OF DISTURBED WEATHER SOUTH-
SOUTHWEST OF ACAPULCO HAS DEVELOPED ENOUGH DEEP CONVECTION AND
CIRCULATION TO BE CLASSIFIED AS A TROPICAL DEPRESSION.  THIS IS A
SUCCESS FOR THE GLOBAL MODELS...WHICH HAVE BEEN INSISTING ON
TROPICAL CYCLONE FORMATION IN THIS AREA FOR THE PAST FEW DAYS.

THE LOW-LEVEL CENTER APPEARS TO BE UNDER THE CONVECTION. THE 
UPPER-LEVEL OUTFLOW IS FAIR TO THE WEST AND THERE MAY BE SOME 
NORTHEASTERLY SHEAR OVER THE SYSTEM AT THIS TIME. HOWEVER...THE NCEP 
GLOBAL MODEL AMPLIFIES THE UPPER-LEVEL RIDGE AND BECAUSE THE 
DEPRESION IS MOVING OVER WARM WATERS...A GRADUAL STRENGTHENING IS 
INDICATED. THIS IN AGREEMENT WITH THE SHIPS INTENSITY FORECAST 
MODEL.  
 
THE INITIAL MOTION IS UNCERTAIN BUT THE BEST ESTIMATE IS 295/04. A 
NARROW MID-LEVEL RIDGE TO THE NORTH OF THE CYCLONE WILL KEEP THE 
SYSTEM ON A SLOW WEST-NORTHWEST TRACK THROUGH 72 HOURS...WELL TO THE 
SOUTH OF MEXICO.  AN AMPLIFICATION OF THE RIDGE MAY FORCE THE 
CYCLONE ON A MORE WESTWARD TRACK BEYOND 3 DAYS.
