On the forecast track, the system will move near the Georgia and South Carolina coasts later today and move along the North Carolina coast on Tuesday. Maximum sustained winds remain near 35 mph (55 km/h) with higher gusts. Some strengthening is possible during the next 48 hours, and the system is expected to become a tropical storm by Tuesday morning and then become post-tropical by Tuesday night. Although satellite and radar data indicate that the associated showers and thunderstorms show some signs of organization, the center of circulation is not yet well defined. Only a slight increase in the definition of the circulation would lead to the formation of a tropical cyclone. * Formation chance through 48 hours...high...90 percent * Formation chance through 5 days...high...90 percent The estimated minimum central pressure is 1007 mb (29.74 inches).
