 SUBTROPICAL STORM ANDREA DISCUSSION NUMBER   3
 NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL   AL012007
 1100 PM EDT WED MAY 09 2007
  
 ANDREA CONSISTS OF SEVERAL SMALL SWIRLS EMBEDDED WITHIN A LARGER
 CIRCULATION. MOST OF THE ASSOCIATED WEATHER IS LOCATED TO THE
 EASTERN HALF OF THE CYCLONE WITHIN A BAND OF MODERATE CONVECTION.
 THE INITIAL INTENSITY IS KEPT AT 40 KNOTS...BUT THESE WINDS ARE
 PROBABLY CONFINED TO THE CONVECTIVE BAND. A PARTIAL QUIKSCAT PASS
 SUGGESTS THAT THE WINDS MAY BE WEAKER. BECAUSE ANDREA IS EXPECTED
 TO REMAIN OVER COOL WATERS IT SHOULD GRADUALLY WEAKEN...AS 
 INDICATED BY SHIPS AND GLOBAL MODELS. ONLY THE GFDL MAKES ANDREA A
 LITTLE BIT STRONGER.  
 
 THE CYCLONE HAS BEEN MEANDERING DURING THE PAST SEVERAL HOURS
 EMBEDDED WITHIN THE CIRCULATION OF A LARGE UPPER TROUGH. ONLY A
 SMALL SOUTHWARD DRIFT IS ANTICIPATED AS THE CYCLONE BECOMES STEERED
 BY THE NORTHERLY FLOW ON THE BACK SIDE OF THE UPPER TROUGH. THIS 
 TROUGH IS FORECAST TO MOVE EASTWARD AND WEAKEN. THIS IS CONSISTENT
 WITH TRACK GUIDANCE WHICH INDEED SUGGESTS VERY LITTLE MOTION OF THE
 CYCLONE OR WHATEVER IS LEFT OVER THE NEXT 2 OR 3 DAYS. 
 
 GIVEN THE UNCERTAINTIES IN THE FORECAST TRACK...INTENSITY...AND WIND
 RADII... THE TROPICAL STORM WATCH REMAINS UNCHANGED AT THIS TIME.
