A storm system will develop along the Gulf Coast on Saturday and track northeast through Sunday. Abundant moisture could bring 2 to 3 inches of rainfall, while strong onshore winds potentially produce significant coastal flooding, according to the National Weather Service.

Widespread rainfall totals of 2 to 3 inches are expected. Localized amounts in excess of 3 inches are possible across coastal SC. This amount of rainfall can produce flooding of low-lying and poorly drained areas, especially in the heaviest rain bands.

Strong winds along the coast will result in above-normal tide levels. The highest tide appears to be Sunday morning around 9 AM. Tides could approach 8.0 feet MLLW at downtown Charleston and 9.3 feet MLLW at Fort Pulaski, Ga. Rainfall occurring around the time of high tide would only exacerbate the flooding.

Rain will spread across the area from west to east Saturday. Then widespread moderate to locally heavy rainfall will be likely Saturday evening through Sunday morning. The rain will gradually taper off during Sunday afternoon.

The high tide at downtown Charleston is 9:07 AM Sunday. The high tide at Fort Pulaski is 9:12 a.m. Sunday. Saltwater flooding is most likely for a few hours leading up to and following high tide.
