24S(HABANA). WARNING 7 ISSUED AT 07/09UTC. TC 24S IS IN AN OVERALL FAVORABLE ENVIRONMENT WITH GOOD RADIAL UPPER LEVEL OUTFLOW, LOW (10-15KT) VERTICAL WIND SHEAR, AND WARM (28-29C) SEA SURFACE TEMPERATURES. THE SYSTEM IS IN A COL BETWEEN THE NEAR EQUATORIAL RIDGE (NER) TO THE NORTH AND A SECONDARY NER TO THE EAST THAT IS SLIGHTLY THE DOMINANT STEERING MECHANISM AND SLOWLY DRIVING THE CYCLONE POLEWARD. AFTER 24H, A SUBTROPICAL RIDGE (STR) WILL BUILD TO THE SOUTH AND ASSUME STEERING, TURNING TC 24S TO A WESTWARD TRACK THEN, AFTER 96H, WEST-SOUTHWESTWARD. TC 24S IS FORECAST TO WEAKEN PRIMARILY DUE TO DIMINISHING UPPER LEVEL OUTFLOW AND BY TAU 36-48, WILL BE REDUCED TO 85KNOTS/US CATEGORY 2. AFTER 48H, INCREASED OUTFLOW FROM THE STR WILL FUEL A SECONDARY INTENSIFICATION PHASE AND BY TAU 120, WILL RE-STRENGTHEN TO 105KTS, POSSIBLY HIGHER WITH RAPID INTENSIFICATION.
24S(HABANA).NUMERICAL MODELS AGREE ON THE GENERAL TRACK SCENARIO. HOWEVER, THE SOLUTIONS DIVERGE SIGNIFICANTLY ALONG- AND CROSS-TRACK DUE TO THE COMPLEX STEERING MECHANISMS. THE JTWC TRACK FORECAST IS PLACED NEAR THE MULTI-MODEL CONSENSUS WITH LOW CONFIDENCE.
24S(HABANA). 07/0757UTC. WEAKENING MICROWAVE SIGNATURE COMPARED TO 24H EARLIER.
24S(HABANA). 07/0034UTC. DMSP.
24S(HABANA). CIMSS Vertical Shear Magnitude : 5.2 m/s (10.0 kts) Direction : 46.3 deg Experimental Vertical Shear and TC Intensity Trend Estimates: UNFAVOURABLE OVER 24H
