HURRICANE FAUSTO DISCUSSION NUMBER  10
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL   EP072008
800 AM PDT FRI JUL 18 2008
 
AN EYE IS NOT YET DISCERNIBLE IN GEOSTATIONARY VISIBLE OR INFRARED
IMAGERY...BUT A SSMIS OVERPASS FROM 1253Z THAT JUST CAME IN REVEALS
ABOUT HALF OF AN EYEWALL HAS FORMED IN THE SOUTHERN SEMICIRCLE. 
DVORAK INTENSITY ESTIMATES AT 12Z WERE A CONSENSUS 65 KT...AND
COMBINED WITH THE MICROWAVE SIGNATURE PROVIDE ENOUGH EVIDENCE THAT
FAUSTO HAS BECOME A HURRICANE...THE THIRD OF THE 2008 EASTERN
PACIFIC SEASON.  CONDITIONS APPEAR RIPE FOR CONTINUED
STRENGTHENING...WITH NOT MUCH WIND SHEAR AND RATHER WARM SSTS ALONG
THE FORECAST TRACK FOR THE NEXT 2-3 DAYS.  THE NEW OFFICIAL
INTENSITY FORECAST PEAKS A LITTLE HIGHER THAN THE PREVIOUS ONE AND
IS CLOSE TO A CONSENSUS OF THE AVAILABLE OBJECTIVE INTENSITY
MODELS.

THE INITIAL MOTION ESTIMATE IS AN UNSURPRISING 285/11.  FEW CHANGES
TO THE MOTION ARE INDICATED BY THE OFFICIAL FORECAST THROUGHOUT THE
FIVE-DAY PERIOD...AS THE CYCLONE WILL BE STEERED BY THE SUBTROPICAL
RIDGE TO ITS NORTH.  THAT RIDGE IS FORECAST TO WEAKEN SLIGHTLY BUT
TEMPORARILY IN A DAY OR TWO AS A LOW MOVES INTO CALIFORNIA...BUT
THE MODELS INDICATE IT WILL BECOME REESTABLISHED ON DAYS 3-5. 
THERE IS SOME SPREAD IN THE LONG-RANGE GUIDANCE TRACKS...BUT THE
CONSENSUS HAS NOT CHANGED MUCH AND NEITHER HAS THE OFFICIAL
FORECAST...WHICH IS MOSTLY A BLEND OF THE GFS...GFDL...AND HWRF.
