A far more tranquil and enjoyable weekend is on tap as temperatures will be near normal with a good mix of sun and clouds. No precipitation concerns are apparent and we are shaping up to have a really nice mid-October weekend.

The flood threat lingers

As has been the case since Matthew, flooding will continue to be a concern along rivers and at the coast.

First, the good news

Flood warnings for Dorchester and Charleston counties were allowed to expire earlier today as additional river rises along the Edisto and Ashley have come to an end. (Thank goodness!)

And now, the iffy news

Flooding continues to be an issue for the Edisto River near Givhans Ferry. Forecasts keep the river in moderate flood for the next several days, though it will be gradually falling during this period. With any luck it will fall below flood stage by the end of next week.

Tidal flooding will also remain an issue for the foreseeable future. Tides as high as 8.1 ft are expected tomorrow morning around 7:30am. This may cause some real flooding issues particularly in the hardest-hit areas from Hurricane Matthew such as Edisto Beach. From the NWS Coastal Flood Watch:


It’s already pretty bad on Edisto Beach, as this Facebook post from the South Carolina Department of Natural Resources shows.

Yes, that’s the beach over top of Palmetto Blvd. Four feet of sand. So you can understand why NWS is concerned about this part of the coast in particular.

For the Charleston area, an 8.1' high tide would create many issues along our coast and on downtown Charleston roads. At this height, roads tend to close as they become filled with salt water. Be sure to be prepared to use alternate routes for a few hours tomorrow morning around the 7:34am high tide and again for a couple hours around the 8:05pm high tide. Thank the upcoming full moon, the Earth’s proximity to the moon at its perigee, and northeast winds around high pressure situated in the northeast.

Tidal flooding will continue to be a threat around times of high tide through early next week. Stay tuned for additional coastal flooding alerts.

Besides Tropical Storm Nicole, which is heading rapidly northeastward into the northern Atlantic, all is quiet. 👍

The next seven days

Dry and slightly above average warm weather will continue through the middle of next week before a storm system approaches from the west. Slight rain chances increase Thursday into next Friday. Stay tuned as things can change. For now, though, enjoy the great weather and just be wary of flooded areas.
