Coastal Flood Advisory for Monday Morning

A coastal flood advisory is in effect for coastal Bryan, coastal Chatham, coastal Liberty, coastal McIntosh, Beaufort, coastal Colleton, Charleston, and coastal Jasper Counties from 5 am to 10 am Monday.

Elevated tides will once again impact the southern South Carolina and southeast Georgia coasts Monday morning. The combination of high astronomical tides and remnant swells from a departing storm well off the coast of the southeast United States...will continue to enhance the tidal departures during the high tide cycle Monday morning. High tide will occur around 7:13 am in Charleston Harbor...7:19 am at the Savannah River entrance...and 8:28 am in Beaufort.

Tide levels are expected to reach between 7.5 and 7.7 feet mean lower low water in the Charleston Harbor...producing moderate coastal flooding along parts of the southern South Carolina coast. Salt water will rise into yards...streets and driveways across parts of downtown Charleston...especially in locations that often experience flooding during the high tide events. Many other coastal locations will also be impacted...including but not limited to Isle of Palms...Sullivans Island...Seabrook Island...Edisto Island...Edisto Beach...Hunting Island and Ladys Island near Beaufort. In addition to the coastal flooding concerns...at least minor beach erosion is expected to occur.

Vehicles that are parked in these flood prone areas should be moved to higher ground. If traveling this morning...pay close attention for water covering the road. Never drive through water of unknown depth.

Tide levels are expected to reach between 9.2 and 9.4 feet mean lower low water at the Savannah River entrance...producing minor coastal flooding along parts of the southeast Georgia coast. Salt water will approach and possibly cover portions of Highway 80 between Savannah and Tybee Island. Other locations that often experience flooding during the high tide events will likely see some impacts from the salt water rise as well. In addition to the coastal flooding concerns...minor beach erosion will also be possible.

A coastal flood advisory indicates that winds and tides will combine to generate some salt water flooding of low-lying areas near the coast. Shallow coastal flooding begins along the southern South Carolina coast when tides in the Charleston Harbor reach 7.0 feet mean lower low water and along the northern Georgia coast when tides reach 9.2 feet mean lower low water at Fort Pulaski.
