 HURRICANE FAUSTO DISCUSSION NUMBER  20
 NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL   EP072008
 800 PM PDT SUN JUL 20 2008
 
 LATEST VISIBLE AND INFRARED IMAGERY INDICATES THAT FAUSTO CONTINUES
 TO MAINTAIN ITS PRESENT INTENSITY.  TAFB AND SAB DVORAK
 ESTIMATES REMAIN AT A CONSENSUS T4.5 AND A PREVIOUS UW-CIMSS AMSU
 INTENSITY ESTIMATE SUPPORTS KEEPING FAUSTO AS AN 80 KNOT HURRICANE.
 
 THE INTENSITY FORECAST REASONING REMAINS CONSISTENT WITH THE
 PREVIOUS OFFICIAL FORECAST AND THE INTENSITY GUIDANCE MODELS.
 ALTHOUGH THE WIND SHEAR CONDITIONS ARE FAVORABLE OVER THE NEXT FEW
 DAYS AS INDICATED BY THE SHIPS MODEL...THE SYSTEM WILL MOVE OVER
 MUCH COOLER SSTS THAT WILL CONTRIBUTE TO WEAKENING THE SYSTEM. ALL
 INTENSITY GUIDANCE MODELS SUGGEST THAT FAUSTO WILL WEAKEN OVER THE
 NEXT FEW DAYS AND IT WILL DISSIPATE INTO A REMNANT LOW IN THE
 EXTENDED PERIOD. 
 
 THE CURRENT MOVEMENT OF FAUSTO IS 310/11. THE SYSTEM IS LOCATED TO
 THE SOUTHWEST OF A DEEP LAYER RIDGE CENTERED OVER NORTHERN MEXICO
 AND THE U.S. SOUTHWEST. MOST TRACK MODEL GUIDANCE SUGGESTS THAT
 FAUSTO WILL CONTINUE ON A NORTHWESTERLY TRACK AND EVENTUALLY MOVE
 TOWARD THE WEST-NORTHWEST LATER ON IN THE FORECAST PERIOD...MAINLY
 IN RESPONSE TO THE DEEP LAYER RIDGE. THE OFFICIAL FORECAST TRACK
 REMAINS CONSISTENT WITH THIS GUIDANCE AND THE PREVIOUS OFFICAL
 FORECAST TRACK.
