 TROPICAL STORM IGNACIO DISCUSSION NUMBER  10
 NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL   EP122009
 800 PM PDT WED AUG 26 2009
 
 MOST OF THE DEEP CONVECTION ASSOCIATED WITH IGNACIO HAS DISSIPATED
 AND WHAT LITTLE REMAINS IS OCCURRING WELL TO THE NORTHEAST OF THE
 LOW-LEVEL CENTER.  THERE HAVE BEEN NO NEW SCATTEROMETER PASSES OVER
 THE CYCLONE AND DVORAK SATELLITE INTENSITY ESTIMATES ARE 35 KT FROM
 TAFB AND SAB.  THE CURRENT INTENSITY IS SET AT 35 KT FOR THIS
 ADVISORY.  A CONTINUED GRADUAL SPIN DOWN OF THE LARGE CIRCULATION
 IS EXPECTED AS THE SYSTEM PASSES OVER PROGRESSIVELY COOLER WATERS
 AND THROUGH AN INCREASINGLY STABLE AIR MASS.  IGNACIO SHOULD WEAKEN
 TO A DEPRESSION TOMORROW AND DEGENERATE INTO A REMNANT LOW IN ABOUT
 24 HOURS.
 
 THE FORWARD SPEED HAS INCREASED AND THE MOTION IS A LITTLE MORE TO
 THE RIGHT AS COMPARED TO EARLIER TODAY.  IGNACIO IS MOVING ALONG
 THE SOUTHWEST PERIPHERY OF A MID-LEVEL HIGH.  AS THE CYCLONE
 BECOMES STEERED MAINLY BY THE LOW-LEVEL ENVIRONMENTAL FLOW...A
 GRADUAL TURN TO THE LEFT IS ANTICIPATED.  THE TRACK GUIDANCE
 INDICATES A SLOWING OF THE FORWARD SPEED OVER THE NEXT COUPLE OF
 DAYS...AND SO DOES THE OFFICIAL FORECAST.
