A low pressure system could develop near the coast of the Southeast U.S. during the next 48 hours. At 8:00 a.m. EDT on Friday the center of a developing low pressure system currently designated as Invest 90L was located at latitude 31.3°N and longitude 79.3°W which put it about 150 miles (240 km) east of Brunswick, Georgia. It was moving toward the east-southeast at 9 m.p.h. (15 km/h). The maximum sustained wind speed was 25 m.p.h. (40 km/h) and there were wind gusts to 35 m.p.h. (55 km/h). The minimum surface pressure was 1017 mb.

Early morning visible satellite images appeared to show that a low pressure system was forming along a nearly stationary front off the coast of the southeast U.S. More thunderstorms were forming in the developing low pressure system and some rotation was evident in satellite loops. Thunderstorms appeared to be organizing into bands. The southern end of an upper level trough over the eastern U.S. was producing westerly that were blowing across the top of the developing low pressure system. Those winds were causing moderated vertical wind shear. The upper level winds were also inhibiting the development of thunderstorms on the western side of the developing low pressure system.

The low pressure system will move through an environment somewhat favorable for the formation of a tropical cyclone during the next 48 hours. It will move over water where the Sea Surface Temperatures are near 28°C. The upper level trough will move northeast of the low pressure system on Saturday and the upper level winds will weaken. An upper level low east of the Bahamas could enhance upper level divergence to the southeast of the developing low pressure system. The National Hurricane Center is indicating the probability is 30% that a tropical cyclone forms during the next 48 hours. A reconnaissance plane has been tentatively tasked to investigate the system on Saturday afternoon, if necessary.
