Tropical Depression MARIE (Text)

ZCZC MIATCDEP4 ALL
TTAA00 KNHC DDHHMM
TROPICAL DEPRESSION MARIE DISCUSSION NUMBER  22
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL   EP142008
800 AM PDT MON OCT 06 2008

A QUIKSCAT PASS FROM ABOUT 12 HOURS AGO INDICATED THAT MARIE WAS A
MARGINAL TROPICAL STORM...AND THE SYSTEM HAS BEEN PRODUCING VERY
LITTLE DEEP CONVECTION SINCE THEN.  THEREFORE IT IS ASSUMED THAT
THE CYCLONE HAS SPUN DOWN TO DEPRESSION INTENSITY BY NOW AND THE
INITIAL WIND SPEED IS SET TO 30 KT.  FURTHER WEAKENING IS LIKELY DUE
TO THE DRY AND STABLE ATMOSPHERIC ENVIRONMENT AND MARIE WILL
PROBABLY BE REDUCED TO A REMNANT LOW IN 24 HOURS...OR LESS.  THE
OFFICIAL INTENSITY FORECAST IS CLOSE TO THE NUMERICAL MODEL
CONSENSUS.

THE MOTION IS ESTIMATED TO BE A WESTWARD DRIFT...270/2.  MARIE IS
STILL RESPONDING...SLIGHTLY...TO THE MID-LEVEL EASTERLY STEERING
FLOW.  THIS IS LIKELY TO BE TEMPORARY AS MOST OF THE TRACK MODEL
GUIDANCE SHOWS MARIE OR ITS REMNANT TURNING WEST-SOUTHWESTWARD TO
SOUTHWESTWARD...AND THEN BEING DRAGGED CYCLONICALLY AROUND THE FLOW
TO THE WEST OF NORBERT.  THE OFFICIAL TRACK FORECAST IS NOT MUCH
DIFFERENT FROM THE PREVIOUS ONE AND ROUGHLY IN THE MIDDLE OF THE
GUIDANCE.
