Honestly it looks to be a TD already imo.
SATELLITE IMAGERY INDICATES THAT SHOWER AND THUNDERSTORMS ASSOCIATED
WITH A VIGOROUS TROPICAL WAVE AND ASSOCIATED LOW PRESSURE ABOUT 400
MILES EAST-SOUTHEAST OF THE CAPE VERDE ISLANDS ARE GRADUALLY
BECOMING BETTER ORGANIZED. IF CURRENT TRENDS CONTINUE...A TROPICAL
DEPRESSION COULD FORM DURING THE NEXT DAY OR TWO AS THIS SYSTEM
MOVES TOWARD THE WEST-NORTHWEST AT 10 TO 15 MPH. THERE IS A HIGH
CHANCE...70 PERCENT...OF THIS SYSTEM BECOMING A TROPICAL CYCLONE
DURING THE NEXT 48 HOURS.
