 TROPICAL STORM KIKA DISCUSSION NUMBER   5
 NWS CENTRAL PACIFIC HURRICANE CENTER HONOLULU HI   CP012008
 500 PM HST THU AUG 07 2008
 
 DVORAK ANALYSES FROM THE CPHC...JTWC AND SAB HAVE SHOWN LITTLE
 CHANGE IN INTENSITY OVER THE PAST SIX HOURS. THE PHFO DVORAK
 ANALYSIS REMAINS 2.5/2.5...THE JTWC ANALYSIS SHOWED A BIT OF
 WEAKENING AT 1.5/2.0 AND THE SAB ANALYSIS SHOWED DEVELOPMENT AT
 2.5/2.5. THE SATELLITE FIXES WERE BASED ON IMAGERY 3 TO 3-1/2 HOURS
 PRIOR TO THIS BULLETIN. OVER THAT TIME THE CLOUD PATTERN HAS SHOWN
 FURTHER DEVELOPMENT. WE HAVE KEPT THE INITIAL INTENSITY UNCHANGED
 AT 35 KT. KIKA CONTINUES MOVING SLIGHTLY NORTH OF WEST WITH LITTLE
 CHANGE IN FORWARD MOTION IN THE PAST 6 HOURS.
  
 COMPUTER MODELS REMAIN CONSISTENT IN KEEPING A FAIRLY STRONG AND
 DEEP AREA OF HIGH PRESSURE OVER THE CENTRAL NORTH PACIFIC THROUGH
 AT LEAST THE NEXT 120 HOURS. THE DEEP EASTERLY FLOW ON THE SOUTH
 SIDE OF THE HIGH WILL KEEP KIKA MOVING ALONG ON A TRACK TOWARD THE
 WEST OR WEST NORTHWEST. THE TRACK GUIDANCE IS EVEN MORE TIGHTLY
 CLUSTERED THAN THE GUIDANCE FROM 6 HOURS AGO. WE HAVE CHANGED THE
 TRACK VERY LITTLE SINCE THE PREVIOUS PACKAGE...KEEPING THE TRACK IN
 THE MIDDLE OF THE MODEL CONSENSUS.
  
 OVER THE NEXT 72 HOURS...KIKA IS FORECAST TO MOVE OVER SLIGHTLY
 COOLER WATERS WHILE SHEAR WILL REMAIN QUITE WEAK. THAT SHOULD ALLOW
 FOR SLOW INTENSIFICATION. BEYOND 72 HOURS...KIKA IS FORECAST TO
 MOVE INTO AN AREA OF STRONGER WESTERLY SHEAR...AND TO START
 WEAKENING. THIS IS THE SAME INTENSITY TREND WE HAVE BEEN
 FORECASTING ON OUR LAST COUPLE OF FORECASTS.
