REMARKS:
080300Z1 POSITION 14.5N0   90.1E0
TROPICAL STORM LINDA (30W) IS DRIFTING WEST-SOUTHWESTWARD
AT 03 KNOTS.  THE WARNING POSITION IS BASED UPON 072330Z5
ENHANCED INFRARED SATELLITE IMAGERY.  ANIMATED INFRARED
SATELLITE IMAGERY INDICATES THAT TS LINDA (30W) IS
EXPERIENCING MODERATE VERTICAL WIND SHEAR CAUSING MUCH
OF THE CONVECTION TO BE CONCENTRATED ON THE NORTHEAST
SIDE.  THE SYSTEM IS EXPECTED TO TRACK WESTWARD AT SLOW
SPEEDS THROUGH 24 HOURS.  BY 36 HOURS, VERTICAL WIND
SHEAR IS EXPECTED TO INCREASE FURTHER CAUSING THE LOW
LEVEL CIRCULATION OF TS LINDA TO BE FULLY EXPOSED.  THE
SYSTEM WILL THEN TRACK IN A NORTH-NORTHWESTWARD
DIRECTION.  TS LINDA (30W) IS FORECASTED TO DISSIPATE
AFTER 48 HOURS OVER THE WATER.  MAXIMUM SIGNIFICANT WAVE
HEIGHT AT 080000Z IS 15 FEET.  REFER TO WWIO30 PGFW FOR
ADDITIONAL SEA HEIGHT INFORMATION.  NEXT WARNINGS AT
080900Z7 (DTG 080751Z3), 081500Z4 (DTG 081351Z0),
082100Z1 (DTG 081951Z6) AND 090300Z2 (DTG 090151Z8).//
