Hurricane KENNETH


ZCZC MIATCDEP1 ALL
TTAA00 KNHC DDHHMM
TROPICAL STORM KENNETH DISCUSSION NUMBER  40
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
8 AM PDT SAT SEP 24 2005
 
MICROWAVE DATA INDICATE THE CENTER OF KENNETH REMAINS NEAR THE
EASTERN PORTION OF THE DEEPEST CONVECTION. SATELLITE INTENSITY
ESTIMATES REMAIN 45 KT FROM TAFB...AND THAT IS THE INTENSITY USED
FOR THIS ADVISORY.
 
THE INITIAL MOTION REMAINS 270/3. STEERING CURRENTS ARE FORECAST TO
REMAIN WEAK FOR THE NEXT 24-36 HOURS AS KENNETH IS EXPECTED TO
REMAIN EMBEDDED WITHIN A LARGE WEAKNESS IN THE SUBTROPICAL RIDGE.
BY 36 HOURS... A MID-LEVEL TROUGH IS FORECAST TO DIG SOUTHWARD TO
THE NORTH OF THE CYCLONE... WHICH WILL ACT TO NUDGE KENNETH
SLIGHTLY SOUTHWARD THROUGH 72 HOURS. AFTERWARDS... THE STEERING
FLOW IS FORECAST TO BECOME MORE EASTERLY AS A RIDGE TO NORTH OF
KENNETH BUILDS IN BEHIND THE TROUGH. REGARDLESS OF THE STEERING
PATTERNS... THE FLOW IS FORECAST TO REMAIN WEAK... SO SOME ERRATIC
MOTION... INCLUDING SMALL LOOPS... WILL BE POSSIBLE.

THE VERTICAL SHEAR IS FORECAST TO WEAKEN TO 2-5 KT IN 24-48 HOURS...
SO SOME SLIGHT STRENGTHENING WILL BE POSSIBLE SINCE KENNETH WILL
STILL BE OVER 27C SSTS. THE MAIN INHIBITING FACTOR WILL BE VERY DRY
MID-LEVEL AIR ENTRAINING INTO THE SYSTEM AT TIMES.
