1. A low pressure area located about 100 miles off the coast of South Carolina is producing disorganized showers and thunderstorms well to the east of its center of circulation. Strong upper-level winds should prevent any significant tropical or subtropical development during the next few days. By late this weekend, the low is expected to interact with a frontal boundary located to its north, which should end the opportunity for tropical or subtropical formation. Regardless of development, the low is forecast to move slowly east-northeastward at about 5 mph, and it could bring gusty winds and locally heavy rain to eastern portions of the Carolinas through the weekend. * Formation chance through 48 hours...low...20 percent. * Formation chance through 5 days...low...30 percent.
