800 AM PDT THU AUG 16 2012
 
SPIRAL BANDING ON THE WESTERN AND SOUTHERN PORTIONS OF HECTOR HAS
PERSISTED DURING THE PAST 6 HOURS...AND A BLEND OF A 0402 UTC AMSU
INTENSITY ESTIMATE AND THE TAFB SATELLITE CLASSIFICATION SUPPORTS
MAINTAINING AN INITIAL INTENSITY OF 25 KT.  HECTOR SHOULD DECAY TO A
REMNANT LOW DURING THE NEXT 24 HOURS...OR POSSIBLY EARLIER...AS IT
TRAVERSES COOLER SEA SURFACE TEMPERATURES AND REMAINS IN A MODERATE
EASTERLY WIND SHEAR ENVIRONMENT.
 
THE INITIAL MOTION IS ESTIMATED TO BE 335/4 KT.  A GENERAL
NORTH-NORTHWESTWARD TRACK IS LIKELY OVER THE NEXT FEW DAYS AS THE
CYCLONE MOVES WITHIN THE LOW-LEVEL SOUTHERLY FLOW GENERATED BY HIGH
PRESSURE TO THE EAST.  THE NHC FORECAST IS SIMILAR TO THE PREVIOUS
ADVISORY AND IS BASED ON THE TVCE MODEL CONSENSUS.
