01W(DUJUAN). WARNING 20 ISSUED AT 22/03UTC.TD 01W IS TRACKING NORTHWESTARD ALONG THE SOUTHERN PERIPHERY OF AN EXTENSIVE SUBTROPICAL RIDGE TO THE NORTH. THE SYSTEM WILL CONTINUE TO TRACK NORTHWESTWARD TO WESTWARD OVER THE CENTRAL PHILIPPINE ISLANDS AND STEADILY DISSIPATE OVER THE NEXT 12 TO 24 HOURS AS VERTICAL WIND SHEAR INCREASES, ALONG-TRACK SEA SURFACE TEMPERATURE DECREASES AND THE CIRCULATION INTERACTS OCCASIONALLY WITH LAND. NUMERICAL MODEL FORECAST GUIDANCE REMAINS IN GOOD OVERALL AGREEMENT REGARDING THE SPEED AND DIRECTION OF THE DISSIPATING SYSTEM, LENDING HIGH CONFIDENCE TO THE CURRENT JTWC TRACK FORECAST. 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.
