TROPICAL DEPRESSION ONE-C DISCUSSION NUMBER   3
NWS CENTRAL PACIFIC HURRICANE CENTER HONOLULU HI
11 PM HST WED AUG 03 2005
 
CONVECTION AROUND ONE-C HAS BEEN ON THE DOWNSWING OVER THE PAST 6 
TO 8 HOURS...WITH A SINGLE CB NOW SPUTTERING OFF AND ON ALONG THE 
SOUTHEAST FLANK OF THE LLCC. SATELLITE FIX ESTIMATES FROM CPHC...SAB 
AND JTWC CONTINUE TO CORRESPOND TO SUSTAINED WINDS OF 25 KT. 

FORECAST GUIDANCE VARIES WIDELY BEYOND 24 HOURS...BUT THE 
STRENGTHENING HIGH NORTH OF THE SYSTEM SHOULD PREVENT MUCH INCREASE 
IN LATITUDE BEYOND 16N. FORECAST TRACK FOR ONE-C IS VERY CLOSE TO 
THE PREVIOUS TRACK...SLIGHTLY TO THE RIGHT OF GFDL GUIDANCE...WITH 
THE SYSTEM FORECAST TO MOVE SLIGHTLY FASTER TOWARDS THE WEST BEYOND 
24 HOURS. 

WE ARE OPERATING ON THE ASSUMPTION THAT CB ACTIVITY WILL INTENSIFY 
OVERNIGHT NEAR THE LLCC. GIVEN THE NEUTRAL SHEAR 
ENVIRONMENT...ONE-C WILL LIKELY CONTINUE TO STRENGTHEN THROUGH 24 
HOURS. THE SHEAR ENVIRONMENT BECOMES UNFAVORABLE AFTER THAT...LIKELY 
CAPPING THE STRENGTH OF ONE-C. THIS SYSTEM IS FORECAST TO REACH 
MINIMAL TROPICAL STORM STRENGTH BY 24 HOURS...MAINTAIN THAT STRENGTH 
THROUGH 36 HOURS...THEN SLOWLY WEAKEN TO DISSIPATION AT 120 HOURS.
