REMARKS (for Meteorologists): 2 AM (18 GMT) FRI 29 JULY POSITION: 18.0N 113.3E.
*TROPICAL STORM 10W (NOCK-TEN), LOCATED APPROXIMATELY 260 NM SOUTH
OF HONG KONG, CHINA, HAS TRACKED WEST AT 11 KNOTS OVER THE PAST SIX
HOURS. ANIMATED INFRARED SATELLITE (IR) IMAGERY SHOWS DEEP
CONVECTION CONCENTRATED OVER THE MAJORITY OF THE SOUTHERN PORTION OF
THE LOW LEVEL CIRCULATION CENTER (LLCC). IR IMAGERY ALSO INDICATES
WARMING CLOUD TOPS OVER THE NORTHERN PORTION OF THE LLCC WITH
LOW LEVEL CLOUD LINES CURVING INTO THE STORM. A 28/1758Z AMSU-B 89
GHZ MICROWAVE SATELLITE IMAGE SHOWS THE LLCC POSITIONED TO THE
NORTHEAST OF THE MAIN DEEP CONVECTION. THE 28/1200Z UPPER AIR STREAM
LINE ANALYSIS SHOWS TROUGHING NORTH OF THE STORM, WHICH IS PROVIDING
SUBSIDENCE AND APPROXIMATELY 20 KNOTS OF NORTHEASTERLY VERTICAL WIND
SHEAR OVER THE NORTHERN PORTION OF TS 10W. ANIMATED WATER VAPOR
IMAGERY SHOWS THAT THE EQUATORWARD OUTFLOW REMAINS EXCELLENT, AND THE
POLEWARD CHANNEL REMAINS INTACT WITH THE TROPICAL UPPER TROPOSPHERIC
TROUGH CELL TO THE NORTHEAST. THE INITIAL POSITION IS BASED ON THE
AFOREMENTIONED AMSU-B PASS WITH POOR CONFIDENCE, AND INITIAL
INTENSITY IS HELD SLIGHTLY HIGHER THAN PGTW, KNES, AND RJTD DVORAK
INTENSITY ESTIMATES OF 45-50 KNOTS. THE STEERING INFLUENCE
CONTINUES TO BE THE SUBTROPICAL RIDGE ANCHORED OVER SOUTHEASTERN
CHINA AND NUMERICAL MODEL GUIDANCE CONTINUES TO CONVERGE CLOSER
TOGETHER ON THE TRACK MOTION WITH EACH MODEL RUN; THEREFORE THIS
FORECAST TRACK LIES CLOSE TO THE CONSENSUS OUTPUT...(more info)
