Coastal flood advisory remains in effect for SC coast Tuesday night

CHARLESTON, SC (WCSC) - A coastal flood advisory remains in effect for all coastal locations in South Carolina from 7 p.m. to midnight on Tuesday.

The NWS has also issued a coastal flood watch from Wednesday morning through Wednesday afternoon for the coast which includes Beaufort and Charleston.

Most rain throughout the Lowcountry Tuesday afternoon has been light to moderate. We are expected to see heavier rain late tonight and into Wednesday morning, and possible thunderstorms.

Authorities have closed a number of streets in the Charleston area due to flooding earlier on Tuesday. 

There is a system out to our west that's bringing a lot of moisture to our area which is going to continue into tonight.

Around the Wednesday morning commute, around 8:30 a.m., you may see some wet weather with widespread rain from Moncks Corner to Georgetown and down towards Charleston.

By 1 p.m., we'll see more breaks in the rain.

Tonight, temperatures will be in the upper 60s with more rain (80% chance) and a possibility of a thunderstorm.

According to forecasters, moderate salt water flooding will happen at the immediate coast within one to two hours before and after the 8:39 p.m. Tuesday high tide at the Charleston Harbor.

Highest tides and moderate salt water flooding will occur near creeks inland from the immediate coast within two to three hours after high tide.

The NWS said flooding is possible with high tide Wednesday morning. Tidal flooding is not expected to be as extensive Tuesday morning, however moderate salt water flooding will still inundate roads, parking lots and beaches.

Some roads could be closed and some properties could be impacted by tidal flooding Tuesday evening.

The NWS is expecting significant beach erosion will continue.

Wednesday's forecast sees us in the lower 80s with scattered showers and thunderstorms possible.
