HURRICANE FAUSTO DISCUSSION NUMBER  17

THERE HAS BEEN LITTLE CHANGE IN THE OVERALL CLOUD PATTERN DURING THE
LAST 6 HOURS AND THE INITIAL INTENSITY ESTIMATE REMAINS 75 KT IN
LINE WITH THE SUBJECTIVE DVORAK SATELLITE INTENSITY ESTIMATES.
HAVING SAID THAT...THE CYCLONE IS NOW ENCOUNTERING RAPIDLY FALLING
SSTS AND WEAKENING SHOULD COMMENCE SOON.  IN FACT...WEAKENING
SHOULD BE BRISK WITH THE SHIPS MODEL DISSIPATING THE SYSTEM IN A
MERE 72 HOURS.  THE OFFICIAL FORECAST DOES NOT SHOW NEARLY AS FAST A
WEAKENING RATE AS SHIPS...BUT DOES INDICATE FAUSTO BECOMING A
TROPICAL DEPRESSION IN 72 HOURS AND DEGENERATING INTO A REMNANT LOW
IN 4 DAYS.
 
FAUSTO CONTINUES TO MOVE NORTHWESTWARD...OR 320/10...TOWARD A
WEAKNESS IN THE SUBTROPICAL RIDGE PRODUCED BY A MID- TO UPPER-
TROPOSPHERIC TROUGH JUST OFF THE WEST COAST OF THE UNITED STATES. 
A TURN TOWARD THE WEST IS EXPECTED IN A COUPLE OF DAYS AS THE
PROGRESSIVELY SHALLOWER CYCLONE IS STEERED BY THE LOW-LEVEL FLOW. 
THE NEW OFFICIAL FORECAST IS SHIFTED A LITTLE TO THE SOUTH TO BE IN
BETTER AGREEMENT WITH THE DYNAMICAL MODELS WHICH APPEAR TO HAVE A
BETTER HANDLE ON THE RAPID WEAKENING.
