TROPICAL STORM GORDON DISCUSSION NUMBER 3
NWS NATIONAL HURRICANE CENTER MIAMI FL AL082012
500 AM AST THU AUG 16 2012
SATELLITE IMAGES INDICATE THAT A SMALL CENTRAL DENSE OVERCAST HAS
FORMED NEAR THE CENTER OF THE CYCLONE. MICROWAVE DATA ALSO SUGGEST
THAT THE CENTRAL FEATURES OF THE SYSTEM HAVE BECOME BETTER DEFINED.
THEREFORE...THE INITIAL INTENSITY IS INCREASED TO 35 KT...IN BEST
AGREEMENT WITH THE TAFB SATELLITE ESTIMATE. GORDON SHOULD BE
MOVING OVER RELATIVELY WARM WATER AND WITHIN A LIGHT-TO-MODERATE
SHEAR ENVIRONMENT FOR THE NEXT COUPLE OF DAYS. ALMOST ALL OF THE
GUIDANCE SHOWS THE STORM CLOSE TO OR BECOMING A HURRICANE WITHIN 72
HRS. THE NHC INTENSITY FORECAST IS SLIGHTLY INCREASED FROM THE
PREVIOUS ONE...BUT REMAINS BELOW THE INTENSITY CONSENSUS FROM 48-72
HR...AND IS NEAR A BLEND OF THE SHIPS/LGEM MODELS.
GORDON APPEARS TO HAVE RECURVED AND IS MOVING ABOUT 015/12 KT. THE
STORM IS EXPECTED TO BE STEERED NORTHEASTWARD THEN EASTWARD AROUND
THE NORTHERN PERIPHERY OF THE SUBTROPICAL RIDGE DURING THE NEXT
COUPLE OF DAYS. AFTER THAT TIME...GORDON SHOULD INTERACT MORE WITH
THE MID-LATITUDE WESTERLIES AND THEN TURN TOWARD THE NORTHEAST AHEAD
OF A TROUGH. WHILE THE MODELS ARE IN GOOD AGREEMENT...THERE HAS
BEEN A SOUTHWARD ADJUSTMENT TO THE TRACK IN THE MAJORITY OF THE
GUIDANCE...AND THE NHC FORECAST IS SHIFTED IN THAT DIRECTION.
WHILE GORDON IS EXPECTED TO BE NEAR THE AZORES IN ABOUT 4 DAYS...
MOST OF THE MODELS SUGGEST THAT IT WILL BE EXTRATROPICAL AT THAT
TIME.
