DISSIPATING AS A SIGNIFICANT TROPICAL CYCLONE OVER LAND

REMARKS:
010900Z POSITION NEAR 16.5N 120.1E.
TYPHOON (TY) 22W (NALGAE), LOCATED APPROXIMATELY 110 NM NORTH OF
MANILA, PHILIPPINES, HAS TRACKED WESTWARD AT 18 KNOTS OVER
THE PAST SIX HOURS. ANIMATED MULTISPECTRAL IMAGERY (MSI) SHOWS THE
EYE HAS FILLED AND INFRARED SATELLITE IMAGERY INDICATES SIGNIFICANT
CONVECTIVE WEAKENING AS TY 22W TRACKS OVER THE RUGGED TERRAIN OF
LUZON. THE INITIAL POSITION IS BASED ON THE MSI WITH LOW CONFIDENCE.
THE INITIAL INTENSITY IS BASED ON THE WEAKENED CONVECTION AND A RJTD
DVORAK ESTIMATE OF 102 KNOTS. WATER VAPOR IMAGERY DEPICTS GOOD
RADIAL OUTFLOW AND IMPROVING POLEWARD OUTFLOW. TY 22W IS CURRENTLY
TRACKING ALONG THE SOUTHERN PERIPHERY OF A DEEP LAYER SUBTROPICAL
STEERING RIDGE, WHICH IS EXPECTED TO REMAIN THE MAJOR STEERING
INFLUENCE THROUGHOUT THE FORECAST PERIOD. TY 22W IS FORECAST TO
CONTINUE WEAKENING AS IT TRACKS ACROSS LUZON AND EMERGE OVER THE
SOUTH CHINA SEA WITHIN THE NEXT 12 HOURS. AS THE SYSTEM CONTINUES TO
TRACK WESTWARD ACROSS THE SOUTH CHINA SEA, IT WILL SLOWLY WEAKEN DUE
TO INCREASED VERTICAL WIND SHEAR AND LAND INTERACTION. AFTER TAU 96,
TY 22W WILL MAKE LANDFALL OVER VIETNAM AND QUICKLY WEAKEN OVER LAND.
NUMERICAL MODEL GUIDANCE IS IN GOOD AGREEMENT EXCEPT FOR WBAR AND
GFDN, WHICH TRACK THE SYSTEM NORTHWESTWARD INTO THE STEERING RIDGE.
ALSO, GFS SLOWS THE SYSTEM AT THE END OF THE FORECAST PERIOD AS IT
ANALYZES A WEAKENING STEERING RIDGE TO THE NORTH. ECMWF, NOGAPS, AND
JGSM MAINTAIN A STRONG STEERING RIDGE; THEREFORE THIS FORECAST IS
MORE IN AGREEMENT WITH THESE MODELS. NEXT WARNINGS AT 011500Z,
012100Z, 020300Z AND 020900Z.//
