POST-TROPICAL CYCLONE GENEVIEVE DISCUSSION NUMBER 39
NWS NATIONAL HURRICANE CENTER MIAMI FL EP072026
1100 AM HST SUN AUG 02 2026
COOL SEA SURFACE TEMPERATURES, MODERATE WESTERLY VERTICAL WIND SHEAR
AND DRY MID-LEVEL AIR HAVE SIGNIFICANTLY IMPACTED GENEVIEVE TODAY.
ORGANIZED DEEP CONVECTION HAS SLOWLY DISSIPATED OVER THE PAST 12 H
OR SO, LEAVING ONLY A SMALL AREA OF SHALLOW CONVECTION NORTH OF THE
NOW COMPLETELY EXPOSED LOW-LEVEL CENTER. GENEVIEVE NO LONGER MEETS
THE CRITERIA OF A TROPICAL CYCLONE, AND THIS WILL BE THE FINAL
ADVISORY ISSUED ON THIS SYSTEM. THE MOST RECENT DVORAK INTENSITY
ESTIMATE FROM TAFB WAS 35 KT, AND OBJECTIVE ESTIMATES RANGE FROM
29-38 KT. THE INTENSITY IS LOWERED TO 35 KT FOR THIS FINAL
ADVISORY.
THE GALE-FORCE LOW IS MOVING QUICKLY TOWARD THE WEST-NORTHWEST
AROUND 11 KT, AND THIS GENERAL MOTION WILL CONTINUE EARLY THIS WEEK
AS THE SYSTEM IS STEERED ALONG THE SOUTHERN PERIPHERY OF A
SUBTROPICAL RIDGE CENTERED TO ITS NORTH. AN EVENTUAL TURN TOWARD THE
NORTHWEST ACCOMPANIED BY A DECREASED IN FORWARD SPEED IS EXPECTED BY
MIDWEEK. GRADUAL WEAKENING OF THE POST-TROPICAL LOW IS FORECAST TO
CONTINUE, WITH THE SYSTEM EXPECTED TO DISSIPATE BY 96 H.
