REMARKS:
081500Z4 POSITION: 7.41 175.9E2
TROPICAL STORM PAKA (05C) CONTINUES TO TRACK TOWARDS THE
WEST AT 8 KNOTS. THE CURRENT INTENSITY IS STILL 45 KNOTS,
HOWEVER, ANIMATED INFRARED SATELLITE IMAGERY INDICATES
THE CONVECTION ASSOCIATED WITH PAKA HAS BECOME MORE
INTENSE OVER THE PAST 3 HOURS. TS PAKA IS FORECAST TO
CONTINUE ON A WESTWARD TRACK THROUGHOUT THE FORECAST
PERIOD UNDER THE INFLUENCE OF LOW TO MID-LEVEL EASTERLY
FLOW. THE SYSTEM IS FORECAST TO MAINTAIN ITS INTENSITY
FOR THE NEXT 24 HOURS AS IT REMAINS IN AN AREA WITH GOOD
UPPER-LEVEL OUTFLOW. AFTER THE 24 HOUR PERIOD, PAKA IS
EXPECTED TO ENCOUNTER MODERATE VERTICAL WIND SHEAR
WHICH WILL CAUSE THE SYSTEM TO WEAKEN THROUGH THE
REMAINDER OF THE FORECAST PERIOD. MAXIMUM SIGNIFICANT
WAVE HEIGHT AT 081200Z1 IS 18 FEET. REFER TO WWPW31 PGFW
FOR ADDITIONAL SEA HEIGHT INFORMATION. NEXT WARNINGS
AT 082100Z1 (DTG 081951Z), 090300Z2 (DTG 090151Z),
090900Z8 (DTG 090751Z) AND 091500Z5 (DTG 091351Z).//
