...CORRECTED AWIPS HEADER TO MIATCDEP3...
 
THE TROPICAL DISTURBANCE LOCATED ABOUT 975 MILES SOUTHWEST OF THE 
SOUTHERN TIP OF BAJA CALIFORNIA HAS BECOME BETTER ORGANIZED AND IS 
NOW TROPICAL DEPRESSION EIGHT-E.  THE INITIAL INTENSITY OF 30 KT IS 
BASED ON DVORAK SATELLITE INTENSITY ESTIMATES OF 30 KT FROM TAFB AND 
25 KT FROM BOTH SAB AND AFWA.

THE INITIAL MOTION ESTIMATE IS 285/7.  HOWEVER...THERE IS 
CONSIDERABLE UNCERTAINTY IN THE EXACT CENTER LOCATION RELATIVE TO 
THE CENTRAL DEEP CONVECTION.  THE CENTER HAS BEEN PLACED ON THE 
EASTERN EDGE OF THE CONVECTIVE CLOUD MASS DUE TO SOME WEAK EASTERLY 
SHEAR.  T.D. EIGHT-E SHOULD TRACK IN A GENERAL WEST-NORTHWEST OR 
WESTWARD DIRECTION THROUGHOUT THE PERIOD OWING TO THE STRONG  
SUBTROPICAL RIDGE TO THE NORTH.  THIS IS CONSISTENT WITH MOST OF THE 
MODEL GUDIANCE AND IS A BLEND BETWEEN CLIPER AND THE BAM MODELS.

AS A RESULT OF THE EASTERLY SHEAR ON THE CYCLONE...ONLY SLOW 
INTENSIFICATION IS FORECAST THROUGH 36 HOURS.  AFTER THAT...THE 
UPPER-LEVEL FLOW BECOMES A LITTLE MORE FAVORABLE FOR DEVELOPMENT.
THE SHIPS INTENSITY MODEL WAS FOLLOWED THROUGH 36 HOURS.
