TROPICAL DEPRESSION ALPHA DISCUSSION NUMBER 6

5 PM EDT SUN OCT 23 2005
IT IS HARD TO DETERMINE IF THERE WAS A SURFACE CIRCULATION OR NOT
ASSOCIATED WITH THE DEPRESSION AFTER CROSSING HISPANIOLA AND I WAS
TEMPTED TO DISSIPATE THE CYCLONE. HOWEVER...A NEW AREA OF CIRCULAR
CONVECTION HAS DEVELOPED JUST NORTH OF HAITI NEAR THE POSSIBLE
CENTER...SO THE INITIAL INTENSITY IS KEPT AT 30 KNOTS. WE ARE
FOLLOWING THE CENTER OF THE CLOUD MASS WHICH IS MOVING TOWARD THE
NORTH-NORTHWEST AT 16 KNOTS IN THE ACCELERATING SOUTHEASTERLY FLOW
AHEAD OF WILMA. BECAUSE THE SHEAR IS LOW AND THE CIRCULATION IS
BACK OVER WATER...A SLIGHT INTENSIFICATION IS POSSIBLE AND ALPHA
COULD TEMPORARILY REGAIN TROPICAL STORM STRENGTH. HOWEVER...MOST
LIKELY THE DEPRESSION WILL INCREASE ITS FORWARD SPEED AND BECOME
ABSORBED BY THE LARGER CIRCULATION OF WILMA IN ABOUT 36 HOURS AND
THEN DISSIPATE.
