TROPICAL STORM DANIEL DISCUSSION NUMBER  11
NWS NATIONAL HURRICANE CENTER MIAMI FL       EP042012
200 PM PDT FRI JUL 06 2012
 
THE STRUCTURE OF DANIEL HAS NOT CHANGED MUCH OVER THE PAST FEW
HOURS...WITH A CDO PERSISTING NEAR THE CENTER BUT NO SIGNS OF AN
EYE FORMING YET IN GEOSTATIONARY IMAGERY. THE INITIAL INTENSITY
REMAINS 60 KT BASED ON A BLEND OF THE 18Z DVORAK FIXES FROM TAFB
AND SAB. WHILE THE SHEAR REMAINS LOW...DANIEL HAS ABOUT 24 HOURS
LEFT BEFORE IT REACHES COOLER WATERS. INTENSIFICATION TO HURRICANE
STATUS IS STILL SHOWN IN THE OFFICIAL FORECAST...WHICH HAS THE
SUPPORT OF MORE OF THE INTENSITY GUIDANCE THIS CYCLE. RAPID
WEAKENING IS EXPECTED AT 48 HOURS AND BEYOND. THE NHC FORECAST IS
CLOSE TO THE SHIPS MODEL THROUGH 48 HOURS AND THE LGEM THEREAFTER. 

A SERIES OF MICROWAVE IMAGES OVER THE PAST FEW HOURS SUGGESTS THAT
THE CENTER OF DANIEL IS LOCATED SOUTH OF PREVIOUS ESTIMATES AND HAS
BEEN MOVING NEARLY DUE WEST OVER THE PAST 12 HOURS AT AROUND 10 KT.
A GENERAL WESTWARD MOTION IS EXPECTED THROUGH THE FORECAST PERIOD
WITH A GRADUAL INCREASE IN FORWARD SPEED AT DAYS 3 THROUGH 5 AS
DANIEL MOVES SOUTH OF A BUILDING SUBTROPICAL RIDGE. THE NEW NHC
TRACK IS A BLEND OF THE PREVIOUS FORECAST ADJUSTED FOR THE MORE
SOUTHERLY INITIAL POSITION AND THE TVCE MULTI-MODEL CONSENSUS. THIS
RESULTS IN A SOUTHWARD ADJUSTMENT OF 15 TO 20 NM THROUGH THE PERIOD
COMPARED TO THE PREVIOUS ADVISORY.
