A growing low-pressure area off the coast of South Carolina is now producing heavy showers and thunderstorms for both North and South Carolina.
The National Hurricane currently says the system has a 10% chance of developing into Tropical Storm Dolly over the next 5 days.
This morning, the National Weather Service issued the following alert:
1. A non-tropical low pressure area located about 150 miles south-southeast of the North Carolina-South Carolina border is producing disorganized showers and thunderstorms over portions of southeastern and eastern North Carolina, including the Outer Banks, and adjacent Atlantic waters. The low is moving slowly toward the north-northeast, and a gradual turn toward the north is forecast later today. Environmental conditions are expected to remain unfavorable for significant development through tonight when the low should move inland over eastern North Carolina. Regardless of development, heavy rainfall could occur over portions of northeastern South Carolina and southeastern and eastern North Carolina through Wednesday. For additional information, see products from your local National Weather Service office.

Regardless of whether or not the system develops into a named storm, it will be bringing heavy rainfall to most of the Carolinas today and tomorrow.
