TROPICAL DEPRESSION LOWELL DISCUSSION NUMBER  16

LOWELL IS A PERSISTENT CYCLONE AS IT CONTINUES TO GENERATE
INTERMITTENT BURSTS OF DEEP CONVECTION.  A 1342 UTC QUIKSCAT PASS
INDICATED THAT MAXIMUM WINDS REMAINS NEAR 30 KT SO THIS WILL BE THE
INITIAL INTENSITY ESTIMATE USED FOR THIS ADVISORY. LOWELL WILL BE
CROSSING THE BAJA PENINSULA DURING THE NEXT 12-24 HOURS...AND LAND
INTERACTION IS EXPECTED TO FINALLY CAUSE LOWELL TO WEAKEN.  IN
FACT...THE LOW-LEVEL CIRCULATION COULD BECOME DETACHED FROM THE
MIDDLE TO UPPER-LEVEL CIRCULATION RESULTING IN DEGENERATION INTO A
REMNANT LOW.  IN 36-48 HOURS...THE REMNANTS OF LOWELL WILL BE
MOVING INTO MAINLAND MEXICO WHERE THE TERRAIN IS QUITE HIGH. 
REGARDLESS OF LOWELL'S STATUS AT THAT TIME...MOISTURE FROM THE
SYSTEM COULD GENERATE SOME LOCALLY HEAVY RAINS.  
 
LOWELL CONTINUES NORTHEASTWARD WITH AN INITIAL MOTION ESTIMATE OF
035/06.  TRACK GUIDANCE HAS NOT CHANGED MUCH AND THE NEW OFFICIAL
TRACK IS SIMILAR TO THE PREVIOUS ONE. 

ALTHOUGH THE PROBABILITY OF LOWELL STRENGTHENING TO TROPICAL STORM
STRENGTH IS LOW...IT IS BEST TO CONTINUE THE TROPICAL STORM WATCH
FOR THE BAJA PENINSULA UNTIL LOWELL PASSES.
