TROPICAL DISTURBANCE 28W (TWENTYEIGHT), LOCATED APPROXIMATELY 164 NM SOUTH-SOUTHWEST OF IWO TO, HAS TRACKED WEST- NORTHWESTWARD AT 08 KNOTS OVER THE PAST SIX HOURS. SCATTEROMETER DATA REVEALS THAT MAXIMUM SUSTAINED WINDS HAVE WEAKENED INTO A 20-KT TROPICAL DISTURBANCE. THE SYSTEM IS INTERACTING WITH A WALL OF DRY AIR ASSOCIATED WITH A SHEAR LINE TO ITS WEST. THIS INTERACTION WILL CAUSE 28W TO DEGENERATE INTO A TROPICAL WAVE WITHIN 24 HOURS, IF NOT SOONER, AS IT TRAVELS WESTWARD ALONG THE LOW-LEVEL FLOW. THIS IS THE FINAL WARNING ON THIS SYSTEM BY THE JOINT TYPHOON WRNCEN PEARL HARBOR HI. THE SYSTEM WILL BE CLOSELY MONITORED FOR SIGNS OF REGENERATION. MINIMUM CENTRAL PRESSURE AT 150600Z IS 1009 MB. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 150600Z IS 8 FEET. FOR SIX-HOURLY UPDATES. // 2826101000 137N1458E 20 2826101006 140N1467E 20 2826101012 143N1478E 25 2826101018 147N1489E 25 2826101100 153N1500E 30 2826101106 156N1505E 30 2826101112 158N1508E 25 2826101118 161N1508E 25 2826101200 164N1504E 25 2826101206 169N1499E 25 2826101212 172N1490E 30 2826101218 175N1482E 25 2826101300 180N1473E 25 2826101306 188N1463E 25 2826101312 194N1453E 25 2826101318 201N1445E 25 2826101400 207N1435E 25 2826101406 213N1428E 25 2826101412 220N1421E 30 2826101418 223N1413E 25 2826101500 223N1405E 20 2826101506 225N1397E 20 NNNN
