TROPICAL DEPRESSION ALMA DISCUSSION NUMBER  31
NATIONAL WEATHER SERVICE MIAMI FL
2 AM PDT SAT JUN 01 2002
 
A QUIKSCAT PASS AT 0130Z INDICATED WINDS IN THE 25-30 KT RANGE...AND 
IT IS PRESUMED THAT SOME ADDITIONAL SPIN DOWN HAS OCCURRED SINCE 
THEN.  THE TRANSFORMATION OF ALMA FROM A TROPICAL CYCLONE TO A NON- 
CONVECTIVE LOW IS NEARLY COMPLETE...AS ALMA HAS NOT GENERATED ANY 
DEEP CONVECTION...A REQUIREMENT FOR TROPICAL CYCLONE STATUS...FOR 
ABOUT 18 HOURS.  ADVISORIES WILL BE DISCONTINUED LATER THIS MORNING 
UNLESS ALMA UNEXPECTEDLY COMES BACK TO LIFE.  A REMNANT CLOSED 
CIRCULATION WILL LIKELY PERSIST FOR ANOTHER COUPLE OF DAYS. 
 
THE INITIAL MOTION ESTIMATE IS STILL STATIONARY.  ALMA IS EMBEDDED 
IN A WEAK LOW-LEVEL STEERING ENVIRONMENT AND IS NOT EXPECTED TO MOVE 
MUCH BEFORE THE CIRCULATION DISSIPATES.
