200 AM PDT SAT JUL 07 2012
HINTS OF AN EYE ARE APPARENT IN THE LAST FEW GEOSTATIONARY
SATELLITE IMAGES. THIS EYE FEATURE HAS BEEN EVIDENT IN MICROWAVE
DATA SINCE ABOUT 0000 UTC...AND A SSMIS PASS AROUND 0400 UTC
INDICATED THAT THE EYE HAS BECOME A LITTLE LESS RAGGED. THE INITIAL
WIND SPEED IS INCREASED A LITTLE TO 70 KT...BASED ON A BLEND OF
DVORAK CLASSIFICATIONS FROM TAFB AND SAB...AND THE LATEST UW-CIMSS
ADT ESTIMATES. DANIEL WILL REMAIN IN A FAVORABLE ENVIRONMENT FOR
STRENGTHENING FOR ANOTHER 12 TO 18 HOURS. THEREAFTER...THE CYCLONE
WILL BE MOVING OVER COOLER WATERS AND INTO A DRIER AIRMASS. THESE
COMBINED FACTORS SHOULD CAUSE STEADY WEAKENING STARTING IN ABOUT 24
HOURS. THE INTENSITY GUIDANCE IS IN REASONABLY GOOD AGREEMENT...
AND THE OFFICIAL FORECAST IS SIMILAR TO THE PREVIOUS ONE.
DANIEL IS MOVING WESTWARD AT AN ESTIMATED 10 KT. A GENERAL WESTWARD
MOTION WITH AN INCREASE IN FORWARD SPEED IS FORECAST FOR THE
NEXT FIVE DAYS AS THE CYCLONE REMAINS TO THE SOUTH OF A BUILDING
SUBTROPICAL RIDGE. THE LATEST ECMWF TRACK HAS SHIFTED A LITTLE TO
THE NORTH...AND THE OFFICIAL FORECAST FOLLOWS THAT TREND AND IS IN
GOOD AGREEMENT WITH THE MULTI-MODEL CONSENSUS.
THE 34-KT WIND RADII OVER THE EASTERN SEMICIRCLE WERE MODIFIED
SLIGHTLY BASED ON AN ASCAT PASS AROUND 0430 UTC.
