Invest 93 Could Gain Subtropical Traits Over Gulf Stream

Keeping an eye on Invest 93 as it moves offshore the Atlantic coast.A storm-force non-tropical low pressure area located a few hundred miles off the North Carolina coast is producing shower and thunderstorm activity primarily west of its center.Recent satellite wind data indicated the low is still frontal, however, over the next couple of days, the low could develop lose its frontal features while it moves slowly north-northeastward over the Gulf Stream, allowing the system to briefly develop subtropical characteristics.By the end of the week, the system is expected to accelerate northeastward where environmental conditions are expected to become unfavorable for additional subtropical or tropical development. Regardless of the status of the system, high winds, coastal flooding, and dangerous surf are expected along portions of the U.S. East Coast during the next few days.The current formation chance through 48 hours and 7 days is 40 percent.
