NWS CENTRAL PACIFIC HURRICANE CENTER HONOLULU HI
5 PM HST MON SEP 19 2005
 
HURRICANE JOVA APPEARS TO HAVE REACHED ITS PEAK STRENGTH AT 100 KNOTS
OR 115 MPH AND WAS ESTIMATED TO BE A T5.5 AT 2 PM HST. SINCE THEN 
CLOUD TOPS HAVE WARMED WITH ITS COLD EYE WALL BEGINNING TO BREAK 
DOWN...ITS STEADY NORTHWESTWARD PATH IS TAKEN INTO SLIGHTLY COOLER
WATER CROSSING THE 80DEGF ISOTHERM AND INTO PARTIALLY SHEARING 
SOUTHWESTERLIES AT UPPER LEVELS. THUS WE WILL MAINTAIN A SLOW 
WEAKENING TREND...AN ABRUPT WEAKENING DOES NOT SEEM WARRANTED BY 
THE MAJORITY OF INTENSITY MODELS. WE WILL CONTINUE THE NORTHWESTWARD 
MOVEMENT THAT HAS BEEN PERSISTENTLY OUTLINED BY NEARLY ALL MODELS...
PARTICULARLY THE CONSENSUS BASED GUNS GUNA AND CONU AND HAVE
SPEEDED UP OUR LATER PERIOD MOTIONS IN DEFERENCE TO THEM.
THIS WOULD PLACE JOVA 300 TO 400 MILES TO THE NORTHEAST OF THE
BIG ISLAND AT ITS CLOSEST POINT FRIDAY/SATURDAY.
