INVEST 91W. UPPER LEVEL ANALYSIS INDICATES INVEST 91W IS IN A FAVORABLE ENVIRONMENT FOR POTENTIAL TROPICAL DEVELOPMENT WITH GOOD WESTWARD AND NORTHWARD OUTFLOW, LOW (10-15KT) VERTICAL WIND SHEAR, AND WARM (29-30C) SEA SURFACE TEMPERATURES. GLOBAL MODELS ARE IN AGREEMENT THAT INVEST 91W WILL TRACK WESTWARD WITH POSSIBLE CONSOLIDATION OVER THE NEXT 5 DAYS.
19S(FARAJI). WARNING 17 ISSUED AT 13/09UTC. 19S IS TRACKING WEST ALONG THE NORTHERN PERIPHERY OF A LOW TO MID-LEVEL SUBTROPICAL RIDGE (STR) ENTRENCHED TO THE SOUTH. AS THE STR BUILDS IN OVER THE NEXT 24 HOURS, TC 19S IS FORECAST TO TAKE ON A SLIGHTLY MORE NORTHWESTWARD TRACK THROUGH THE REMAINDER OF THE FORECAST PERIOD. THE OVERALL ENVIRONMENT HAS BECOME INCREASINGLY UNFAVORABLE, WITH MODERATE (15-20 KTS) NORTHWESTERLY WIND SHEAR AND CONVERGENT UPPER-LEVEL FLOW FROM A DEEP UPPER-LEVEL LOW TO THE SOUTHWEST IMPINGING THE SECONDARY CIRCULATION. AS THE SYSTEM CONTINUES MOVING WEST IT WILL ENCOUNTER INCREASINGLY DRIER AIR IN THE LOW TO MID-LEVELS, WHICH COMBINED WITH THE PERSISTENT CONVERGENT NORTHWESTERLY FLOW ALOFT, WILL LEAD TO STEADY WEAKENING WITH INTENSITY FORECAST TO FALL BELOW 35KNOTS BY 72HOURS.
19S(FARAJI). NUMERICAL MODEL GUIDANCE REMAINS IN OVERALL GOOD AGREEMENT, WITH A SLIGHT INCREASE IN SPREAD TO 325KM AT 72H, LENDING HIGH CONFIDENCE TO THE JTWC FORECAST TRACK.
19S(FARAJI). 13/0915UTC. ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI) CONTINUES TO SHOW THE EFFECTS OF PERSISTENT NORTHWESTERLY SHEAR, WHICH IS DISPLACING FLARING CONVECTION TO THE SOUTHEAST OF THE PARTIALLY EXPOSED LOW LEVEL CIRCULATION CENTER (LLCC).
19S(FARAJI). 13/0341UTC. AMSU-B 89GHZ MICROWAVE IMAGE INDICATED A WELL- DEFINED LOW LEVEL CORE CENTERED TO THE NORTH OF THE CONVECTIVE MASS AND LENT HIGH CONFIDENCE TO THE INITIAL POSITION.
INVEST 93S. NUMERICAL MODEL GUIDANCE DEPICTS THE SUBTROPICAL SYSTEM OVER-LAND.
