THIS BAROCLINIC EFFECT, COMBINED WITH THE EFFECT OF THE PRESSURE GRADIENT WITH THE SUBTROPICAL RIDGE, ENABLED GALES TO BE MAINTAINED. A SUBJECTIVE ANALYSIS BY DVORAK SUGGESTS THAT BHEKI IS ONCE AGAIN A MODERATE TROPICAL STORM, WITH MAXIMUM WINDS ESTIMATED AT BETWEEN 35 AND 40 KT. BHEKI CONTINUES ITS SOUTH-WESTERLY TRACK. ITS MOVEMENT IS DRIVEN BY LOW-LEVEL FLOWS ON THE NORTHERN AND WESTERN SIDES OF THE MASCAREIGNES ANTICYCLONE. THE VARIOUS MODELS ARE IN GOOD AGREEMENT ON A TRACK SLIGHTLY TO THE SOUTH OF REUNION, BEFORE PLUNGING TOWARDS SOUTHERN LATITUDES AT THE START OF THE WEEKEND, CAUGHT UP BY THE MID-LATITUDE TROUGH TO THE WEST OF THE SYSTEM. BEHKI IS LIKELY TO MAINTAIN ITS INTENSITY FOR THE TIME BEING, BEFORE WEAKENING OVER THE NEXT 12 HOURS, AS SHOWN BY THE ISPS OF THE AROME AND IFS MODELS. NEVERTHELESS, THIS WEEKEND, IN A HIGHLY SHEARED CONTEXT, BEHKI SHOULD EVOLVE INTO A RESIDUAL SYSTEM DEVOID OF ANY PERSISTENT CONVECTIVE ACTIVITY NEAR THE CENTER, THEN DISSIPATE TO THE SOUTHEAST OF THE MALAGASY COAST. THIS SYSTEM NO LONGER GENERATES IMPACTS ON INHABITED LAND.=
