TROPICAL DEPRESSION TEN-E DISCUSSION NUMBER   7
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL

THERE HAS BEEN NO SIGNIFICANT CHANGE IN THE SATELLITE PRESENTATION
OF THE DEPRESSION. THE CENTER CONTINUES TO BE DIFFICULT TO LOCATE
BUT IT APPEARS TO BE TO THE EAST OF THE WEAKENING THUNDERSTORM
ACTIVITY. T-NUMBERS REMAIN ABOUT 1.5 AND 2.0 ON THE DVORAK SCALE SO
INITIAL INTENSITY IS KEPT AT 30 KNOTS.  VISIBLE IMAGES LATER TODAY
WILL LIKELY HELP US TO HAVE A BETTER ESTIMATE OF THE LOCATION AND
THE INTENSITY.

THE DEPRESSION IS LOCATED SOUTH OF A STRONG HIGH PRESSURE RIDGE
WHICH IS FORCING THE CYCLONE ON A TRACK SOUTH OF DUE WEST. THIS
PERSISTENT HIGH IS FORECAST TO CHANGE LITTLE SO THIS GENERAL 
MOTION IS EXPECTED TO CONTINUE DURING THE NEXT 5 DAYS. TRACK
GUIDANCE IS IN VERY GOOD AGREEMENT...AND MOST OF THE MODELS ARE
TIGHTLY PACKED INDICATING A GENERAL WESTWARD MOTION. 

THE SOUTH OF DUE WEST MOTION WILL KEEP THE DEPRESSION OVER
RELATIVELY WARMER WATERS AND THE SHEAR IS EXPECTED TO REMAIN WEAK.
THEREFORE...A GRADUAL STRENGTHENING IS INDICATED AND THE FORECAST
FOLLOWS THE SHIPS MODEL CLOSELY. THE GFDL IS A LITTLE MORE
AGGRESSIVE. HOWEVER...THE INTENSITY FORECAST IS HIGHLY UNCERTAIN
AND THE DEPRESSION COULD EASILY WEAKEN INSTEAD.
