Ya gotta love Avila.... Tropical Storm ZETA Discussion -------------------------------------------------------------------------------- Home Public Adv Fcst/Adv Discussion Strike Probs Maps/Charts Archive -------------------------------------------------------------------------------- 000 WTNT45 KNHC 040231 TCDAT5 TROPICAL STORM ZETA DISCUSSION NUMBER 19 NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL 10 PM EST TUE JAN 03 2006 ZETA IS A TENACIOUS CYCLONE AND BASED ON DVORAK CLASSIFICATIONS THE WINDS ARE AT LEAST 55 KNOTS. THE CLOUD PATTERN IS IMPRESSIVE AND CONSISTS OF AN AREA OF MODERATE CONVECTION NEAR THE CENTER AND A CYCLONICALLY-CURVED CONVECTIVE BAND TO THE NORTHEAST. THE OUTFLOW REMAINS ESTABLISHED AND THERE ARE NO SIGNS OF STRONG SHEAR. THE GFDL INSISTS ON MAKING ZETA A HURRICANE AS AN UPPER-LEVEL SHARP TROUGH APPROACHES. THIS COULD BE A CASE OF TROUGH INTERACTION AIDING INTENSIFICATION. I WILL NOT BE SURPRISED IF THE GFDL SOLUTION TURNS OUT TO BE CORRECT. IT HAS ALREADY BEAT ME A FEW TIMES. HOWEVER...FOR THE SAKE OF CONTINUITY ONLY...THE INTENSITY FORECAST KEEPS ZETA WITH 55 OR 50 KNOTS FOR THE NEXT 24 TO 36 HOURS WITH A WEAKENING THEREAFTER. |
