IN THOSE CONDITIONS, THE ACTUAL EXTRATROPICAL TRANSITION WILL SOON BE COMPLETED. THE LOW LEVEL CLOCKWISE CIRCULATION IS ASYMMETRICAL AND THE STRONG WIND EXTENSION IS MORE IMPORTANT IN THE SOUTHEASTERN DUE TO THE GRADIENT WITH HIGH PRESSURES. THE SYSTEM IS EXPECTED TO EVACUATE RAPIDLY SOUTHEASTWARDS.
