59. WILL SLOWLY BEGIN TO WEAKEN IN INTENSITY FROM 40 KNOTS TO 35 KNOTS
    
60. BY TAU 24 AS THE ENVIRONMENT WILL BECOME LESS FAVORABLE DUE TO
    
61. INCREASED VWS. AFTER TAU 24, TC 02S WILL MAKE A SLIGHT TURN AND
    
62. HEAD ON A MORE WEST-SOUTHWESTWARD TRACK AS IT WILL ATTEMPT TO ROUND
    
63. THE STR AXIS. HOWEVER, THE SYSTEM WILL BEGIN TO DISSIPATE AT THIS

2.B LONGER-RANGE OUTLOOK:
NIL


2.C ADDITIONAL INFORMATION:
OVER THE LAST FEW HOURS, CONVECTIVE ACTIVITY MAINTAINED MAINLY IN THE
SOUTH WESTERN QUADRANT IN RELATION WITH A DEEP NORTHEASTERLY SHEAR
STILL MODERATE TO STRONG (20KT ACCORDING TO CIMSS DATA). A LARGE PART
OF THE LOW LEVEL CIRCULATION IS EXPOSED. NEVERTHELESS, THE SYSTEM
MOVEMENT IN THE SAME DIRECTION AS SHEAR AS WELL AS THE CONVECTIVE
ACTIVITY ALLOWED THE INTENSIFICATION OF THE SYSTEM. LAST NIGHT'S AND
THIS MORNING'S ASCAT SWATHS SHOW THE PRESENCE OF GALE FORCE WINDS,
ESPECIALLY IN THE SOUTH WESTERN QUADRANT. THE SYSTEM HAS BEEN NAMED
ASHLEY BY THE MAURITIAN METEOROLOGICAL SERVICE.

IN TERMS OF TRACK, ASHLEY IS MOVING ON THE EDGE OF THE SUBTROPICAL
RIDGE GENERATING A WESTWARD MOVEMENT CURRENTLY. WITH THE EASTWARD
SHIFT OF THESE HIGH PRESSURES, THE SYSTEM SHOULD RESUME A
WEST-SOUTHWESTWARD TRACK.

ASHLEY SEEMS TO HAVE REACHED ITS PEAK INTENSITY AND SHOULD WEAKEN IN
THE NEXT FEW HOURS, STILL UNDER THE UNFAVORABLE INFLUENCE OF THE
STRONG SHEAR AND DRY AIR INTRUSIONS. THE SYSTEM SHOULD EVOLVE INTO A
RESIDUAL SYSTEM BY THE END OF THE WEEK.=

2.C ADDITIONAL INFORMATION:
T=2.0 CI=2.0

DURING THE LAST HOURS, THE CONVECTIVE ACTIVITY OF TROPICAL STORM
ASHLEY SLIGHTLY DECREASED BUT IS STILL PRESENT IN THE SOUTHWEST
QUADRANT OF THE SYSTEM. WITH THE STILL MODERATE TO STRONG
NORTHEASTERLY UPPER SHEAR (20KT ACCORDING TO CIMSS DATA), THE LOW
LEVEL CENTER CONTINUES TO BE EXPOSED. WITHOUT ANY NEW DATA (ASCAT OR
MICROWAVE), THE MAXIMUM WINDS ARE MAINTAINED AT 40KT.

IN TERMS OF TRAJECTORY, THE SUBTROPICAL RIDGE THAT WAS DRIVING THE
WESTWARD FLOW IS PROGRESSIVELY SHIFTING EASTWARD AND BECOMING MORE
NORTHEAST/SOUTHWEST ORIENTED. ASHLEY SHOULD THEREFORE HAVE A MORE
WEST-SOUTH-WEST TO SOUTH-WEST TRAJECTORY FOR THE NEXT 48 HOURS.

IN TERMS OF INTENSITY, ASHLEY REACHED ITS PEAK IN THE LAST HOURS AND
SHOULD PROGRESSIVELY WEAKEN. INDEED, THE STRONG SHEAR AND THE DRY AIR
INTRUSIONS WILL FAVOUR AN EVOLUTION INTO A RESIDUAL SYSTEM WITHIN THE
NEXT 48H.

ASHLEY DOES NOT THREATEN POPULATED AREAS.=
