| #47284 (Received by flhurricane at: 4:49 PM 20.Sep.2005) TCDAT3 HURRICANE RITA DISCUSSION NUMBER 13 NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL 5 PM EDT TUE SEP 20 2005 THERE ARE NO NEW DATA WHICH SUPPORT STRONGER WINDS SINCE THE 87-KNOT PEAK SURFACE WIND MEASURED BY THE STEPPED FREQUENCY RADIOMETER... THE 93-KNOT SURFACE WIND FROM A DROPSONDE IN THE EYEWALL...AND ABOUT 100 KNOTS ON THE DOPPLER RADAR. THE CLOUD PATTERN REMAINS WELL-ORGANIZED WITH AN INTERMITTENT RAGGED EYE AND AN IMPROVING OUTFLOW. INITIAL INTENSITY REMAINS AT 85 KNOTS. GLOBAL MODELS CONTINUE TO HAVE RITA WITH A DEEP CIRCULATION UP TO 200 MB SURROUNDED BY A LARGE-SCALE UPPER-LEVEL ANTICYLONE. THIS PATTERN SUGGESTS STRENGTHENING AND SO DOES THE OFFICIAL FORECAST. THE INTENSITY FORECAST IS IN BETWEEN THE GFDL AND SHIPS MODELS BUT NOT AS AGGRESSIVE AS THE LATTER WHICH BRINGS RITA TO 125 KNOTS. HOWEVER SUCH INTENSIFICATION IS POSSIBLE. RITA CONTINUES TO BE STEERED WESTWARD AT ABOUT 13 KNOTS...BY A LARGE RIDGE OF HIGH PRESSURE ORIENTED EAST-WEST OVER THE SOUTHERN UNITED STATES. THE RIDGE IS FORECAST TO MOVE EASTWARD LEAVING A WEAKNESS IN THE WESTERN GULF OF MEXICO. THIS PATTERN SHOULD FORCE RITA TO TURN GRADUALLY TO THE WEST-NORTHWEST AND NORTHWEST BEYOND 48 HOURS TOWARD THE TEXAS COAST. THE OFFICIAL TRACK FORECAST CONTINUES TO BE OF RELATIVELY HIGH CONFIDENCE SINCE GUIDANCE IS TIGHTLY CLUSTERED... MAINLY DURING THE FIRST 72 HOURS. THEREAFTER...THE GUIDANCE SPREAD IS LARGER BUT MOST OF THE MODELS STILL BRING RITA TO THE TEXAS COAST. ALL INDICATIONS ARE THAT RITA AS AN INTENSE HURRICANE WILL BE APPROACHING THE TEXAS COAST IN ABOUT 3 DAYS.
