That's a long one, and Tropical Storm Warnings may be required tomorrow for portions of SC/GA:
1. A small low pressure system is located about 425 miles east-southeast of Savannah, Georgia. The associated shower and thunderstorm activity has become less organized since earlier this afternoon, becoming displaced to the northwest of the surface center due to strong upper-level winds. The low is forecast to move quickly west-northwestward at 15 to 20 mph, crossing over the warmer waters of the Gulf Stream Monday morning, and it has some potential to become a tropical depression or tropical storm before reaching the coast of Georgia or southern South Carolina by Monday evening. If the system becomes more organized overnight or on Monday, then tropical storm warnings could be required for a portion of the Georgia and South Carolina coasts with short notice. Regardless of development, a few inches of rain are possible along the immediate coasts of Georgia and southern South Carolina through Monday night. An Air Force Reserve Unit reconnaissance aircraft is scheduled to investigate the system Monday afternoon, if necessary. * Formation chance through 48 hours...medium...50 percent. * Formation chance through 5 days...medium...50 percent. 2. An area of low pressure associated with a tropical wave is producing a small cluster of showers and thunderstorms over the eastern tropical Atlantic Ocean. Some slow development is possible through the end of the week while this system moves quickly westward to west-northwestward at about 20 mph, likely reaching the Lesser Antilles late Wednesday or Wednesday night. * Formation chance through 48 hours...low...20 percent. * Formation chance through 5 days...low...30 percent.
