12S(ELOISE). WARNING 8 ISSUED AT 20/21UTC. THE CENTER HAS REEMERGED OVER WATER. ELOISE IS TRACKING ALONG THE NORTHWESTERN PERIPHERY OF A SUBTROPICAL RIDGE (STR) POSITIONED TO THE SOUTHEAST AND THROUGH A FAVORABLE ENVIRONMENT CHARACTERIZED BY WARM (28-29 CELSIUS) SEA SURFACE TEMPERATURES (SST), LOW (10-15 KTS) VERTICAL WIND SHEAR (VWS) AND ROBUST EQUATORWARD AND MODERATE POLEWARD OUTFLOW ALOFT. THESE FAVORABLE CONDITIONS ARE EXPECTED TO CONTINUE THROUGH 48H AND RESULT IN A PEAK INTENSITY OF 90 KNOTS/CATEGORY 2 BY THIS TIME. THE SYSTEM WILL CONTINUE TO TRACK ALONG THE STEERING STR AND MAKE LANDFALL NEAR BEIRA, MOZAMBIQUE BETWEEN 48H AND 72H, WITH FURTHER INTENSIFICATION LIKELY TO OCCUR PRIOR TO LANDFALL. THEREAFTER, THE SYSTEM WILL BEGIN TO DISSIPATE OVER LAND DUE TO INCREASING VWS AND INTERACTION WITH THE UNDERLYING TERRAIN AND COMPLETE DISSIPATION OVER LAND BY 96H.
20/2134UTC. MICROWAVE DEPICTED THE SHEARED SIGNATURE OF 13S.
21/0123UTC. 12S(ELOISE).STRONG BAND WITH HEAVY RAIN AFFECTING WESTERN MADAGASCAR.
13S(NONAME). NUMERICAL MODEL GUIDANCE IS IN POOR AGREEMENT WTIH TWO DISTINCT POSSIBLE SOLUTIONS. THE GFS AND GFS ENSEMBLE BRING THE SYSTEM INTO MUCH MORE INTERACTION WITH A DEEPER MID-LATITUDE TROUGH AND HENCE TURN THE SYSTEM EASTWARD AFTER 24H. THE REMAINDER OF THE CONSENSUS MEMBERS INDICATE A MORE POLEWARD TRACK, ULTIMATELY TURNING WESTWARD AFTER 72H, WHILE THE NAVGEM TRACK IS NEARLY STRAIGHT POLEWARD. AT THIS TIME, THE GFS SOLUTION IS CONSIDERED UNLIKELY AND THE JTWC FORECAST TRACK LIES JUST TO THE WEST OF THE MULTI-MODEL CONSENSUS AND CLOSE TO, BUT FASTER THAN, THE ECWMF TRACKER WITH LOW CONFIDENCE.
12S(ELOISE).NUMERICAL MODEL TRACK GUIDANCE IS IN TIGHT AGREEMENT WITH A 320 KM SPREAD IN ACROSS TRACK SOLUTIONS AT LANDFALL. THIS SPREAD DECREASES TO 230 KM WHEN THE FAR LEFT OF TRACK NAVGEM SOLUTION IS NEGLECTED. THIS TIGHT AGREEMENT IN MODEL GUIDANCE LENDS OVERALL HIGH CONFIDENCE IN THE JTWC FORECAST TRACK WHICH IS PLACED NEAR THE MULTIMODEL CONSENSUS.
21/0315UTC. THE JTWC IS ISSUING 12HOURLY WARNINGS FOR 12S(ELOISE) AND 13S(NONAME). 3 HOURLY SATELLITE BULLETINS ARE ISSUED FOR THE 3 SYSTEMS.
21/00UTC.
