TC 19P IS FORECAST TO TRACK SOUTH- EASTWARD THROUGH THE FORECAST PERIOD ALONG THE SOUTHWEST PERIPHERY OF THE MID-LEVEL RIDGE LOCATED NORTH AND EAST OF THE SYSTEM. TC 19P IS FORECAST TO DISSIPATE AS A SIGNIFICANT TROPICAL CYCLONE IN AN ENVIRONMENT OF MODERATE VERTICAL SHEAR. THIS FORECAST IS BASED ON A BLEND OF NOGAPS, UKMET (EGRR), TCLAPS, AVN, WBAI AND TLAPS MODELS. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 221800Z3 IS 18 FEET. THIS IS THE FINAL WARNING ON THIS SYSTEM BY THE JOINT TYPHOON WARNING CENTER (NAVPACMETOCCEN). THE SYSTEM WILL BE CLOSELY MONITORED FOR SIGNS OF REGENERATION.//
