15OCT26. 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.
