Those of you in the Frogmore beach communities (Tybee, Hilton Head, Fripp, etc.) as well as on the tidal creeks along the GA/SC coast should be aware there is another higher than normal tide in the morning, might top 10.5ft at the Fort Pulaski gauge.
The official guidance from NWS says this about what is expected at each water level:
9.5 – At 9.5 ft MLLW, minor coastal flooding occurs. Flooding will begin to impact Shipyard Road to Burnside Island. Parts of Ft Pulaski National Monument will begin to flood, including several trails. Flooding will also begin to impact Tybee Island including Catalina Dr and Lewis Ave. In Bryan County, water could breach docks near Ft McAllister and flooding will impact portions of Mill Hill Rd. In Liberty County, flooding impacts the Halfmoon Landing area and Cattle Hammock Rd near Bermuda Bluff subdivision.
10 – At 10.0 ft MLLW, moderate coastal flooding occurs. Shipyard Rd will be impassable, isolating residents on Burnside Island. Water will start to encroach on HW-80 and as the tide gets closer to 10.5 ft MLLW, could begin to cover portions of the roadway. Flooding will expand on Tybee Island and Catalina Dr and Lewis Ave will be impassable. Flooding will also impact Wilmington Island, the Coffee Bluff community, Ossabaw Island, Sapelo Island, and portions of HW-17 south of Darien.
10.5 – At 10.5 ft MLLW, major coastal flooding occurs. Damaging flooding is expected, expanding along the entire southeast Georgia coast. Flooding will likely cause the closure of HW-80, isolating residents on Tybee Island. Several other island communities will also likely become isolated due to flooded and impassable roadways. On Tybee Island, widespread significant flooding is expected with numerous properties impacted.
That last may sound a bit dire, but remember it’s only expected to just top 10.5 feet. That is about two feet above our average high tide levels, those of you who live in vulnerable areas know what to expect. We get these levels a couple of times a year, so those inland or in places that don’t normally flood with abnormally high tides don’t need to worry.
Looks like the Ogeechee has crested and is starting to drop.
