This system is expected to track northwest tonight into Monday, before reaching the Carolina Coast and shifting inland Monday afternoon. The disturbance is then forecast to track northwest across North Carolina, then north away from the region heading into the middle of the week. Given the expected track, the main impacts associated with this system will be tropical storm force wind gusts, high surf, rip currents and moderate rains, with highest rainfall amounts across far northern portions of Charleston and Berkeley Counties where total rainfall amounts up to 1 to 2 inches are possible tonight into Monday evening. Although life-threatening storm surge is not expected locally with this disturbance, minor coastal flooding is possible along the Charleston and Coastal Colleton Coast with the evening and morning tide cycles through Monday. The combination of elevated tide levels and high surf could also result in minor to moderate levels of beach erosion along much of the Southeast South Carolina Coast.

Potential impacts in this area include: - Damage to porches, awnings, carports, sheds, and unanchored mobile homes. Unsecured lightweight objects blown about. - Large tree limbs broken off.
