The eighteenth named storm of the season, Sub Tropical Storm Sean has formed well off the US coastline.
At 5:00 am Tuesday, Sean was located at 27.2 N, 69.4 W, or about 720 miles off the North Carolina coastline. The storm had sustained winds of 45 mph and was stationary.
A strong cold front moving off the east coast on Thursday will turn Sean to the northeast and push the storm well out to sea by late week. The storm will have no impact on eastern Carolina.
A sub-tropical storm is more of a hybrid type storm with both tropical and non-tropical characteristics. Sub tropical storms generally have a wider wind field without a tight center of circulation.
